This invention is related to a method of making a lead storage battery with a thixotropic gel as electrolyte consisting substantially of a sulphuric acid and a gelling agent. The object is to provide a lead storage battery which is maintenance free, leak-proof and of a long cycle life while permitting filling of the electrolyte independently of the plate dimensions including the superficial extent...

The mixture is driven through a rotor under the combined effect of a drop in pressure between the upstream side and downstream side of this rotor, and the rotation of the latter. According to the invention, the rotor consists of a stack of joined discs (36), each of which is pierced with a set of helical passages (62). Each of these passages (62) is limited by solid walls (64, 66, 68, 70) and open...

PURPOSE:To stabilize creep torque by determining the target idling speed in a running range during an automatic choke being in operation according to the water temp. of engine, and by controlling the transmission capacity of a start clutch on the basis of this target idling speed. CONSTITUTION:This automatic starting clutch is used in combination with a speed changer and an engine equipped with an...

PURPOSE:To reduce the dispersion of responsiveness due to the temperature variation of working oil by settig the gain of a differential means high when the temperature of the working oil in a continuously variable transmission is low, in a PID (proportion, integration, differential) operation means for correcting the deviation for the aimed value such as engine speed. CONSTITUTION:The PID operatio...

PURPOSE:To improve the following performance to an aimed value by adding the output of a means for determining the fundamental operation quantity according to the operation signal, into the output of a PID (proportional, integration, differential) operation means for correcting the deviation for the aimed value such as engine revolution speed, etc. CONSTITUTION:The PID operation means is constitut...

A vehicle control and guidance system in which a desired route for the vehicle is stored in the vehicle in the form of co-ordinates in a ground reference frame. The "vectors" between these junction points are divided by successive reference points into incremental vectors, the reference points being generated ahead of the vehicle at regular intervals. A dead reckoning system predicts the position ...

A borehole logging tool and cryostat therefor to maintain a semiconductor detector at cryogenic temperatures. The cryostat has an elongate single-phase heat sink of solid, thermally conductive material on which the detector is removably mounted. The other end of the heat sink is arranged to receive a liquid cryogen or the cold finger of a helium refrigerator, which is removed before a logging run;...

A water-soluble, low viscosity, single-phase resinous solution useful as an impregnating resin is made by admixing a hydroxy group-containing compound selected from a phenol, a substituted phenol or mixtures thereof; an aldehyde; and an amino-triazine, in a basic reaction medium where the pH of the admixture is over 7, then simultaneously co-reacting the admixture to provide a resinous solution wh...

PURPOSE:To improve the overall efficiency of a load decentralizing method for computer by allocating automatically jobs so that the load is averaged among the computer groups connected to a LAN. CONSTITUTION:A job command received from a LAN via an input medium 1 or a communication control part is given to a job executing part 3 via an input control part 2 and carried out there. The result of this...

1. A dry-shaving apparatus comprising at least one slidable shutter (3) for optionally covering or exposing a shear foil (7) of the dry-shaving apparatus, characterized in that in a dry-shaving apparatus comprising a shavinghead frame (2) which carries the shear foil (7) and which is detachably secured to a basic apparatus (1) by means of at least one resilient latch (12) the shutter (3) is slidab...

In a dry shaver with at least one roll-type cover (4), slidable on the apparatus housing (3) and serving to cover or free a screen shaving foil as desired, the wall face (14) of the roll-type cover facing the apparatus housing extends at a distance from the apparatus housing, at least one slideway (15; 16) being active between the roll- type cover and the apparatus housing, producing a contact pat...

In a dry-shaving apparatus comprising a slidable shutter (3) for optionally covering or exposing a shear foil of the dry-shaving apparatus an arm (15) of a slide (14) for actuating a switch (11) in the motor circuit extends in the path of the shutter end which is remote from the shear foil when the shutter is moved away from the shear foil to expose the shear foil for the purpose of shaving, the f...

1. A dry-shaving apparatus comprising a slidable shutter (3) for optionally covering or exposing a shear foil (9) of the dry-shaving apparatus, by means of which shutter the circuit of the motor for driving the dryshaving apparatus is closed when said shutter (3) is slid away from the shear foil (9) and exposes said shear foil to allow shaving, said position of the shutter (3) being locked by mean...

PURPOSE:To avoid adhesion of liquid substance to an end face part of a piston through reactive curing, by a method wherein an end face part of the piston of a mixing injection machine is provided with a porous body holding a mold release agent. CONSTITUTION:Under a state where a piston 10 takes a forward movement position, a molding tool and a top force 8a of a mixing head 8 are broken. Then a mol...

PURPOSE:To avoid adhesion of an uncured molding material to an end face part of a piston, by a method wherein a curing accelerator is supplied to a liquid substance mixed up with each other within a mixing injection machine in the latter term of a period during which the liquid substance is injected into a molding tool. CONSTITUTION:When a piston 10 takes a backward movement position, an isocyanat...
