PURPOSE:To increase the performance of a lead storage battery by improving the flow of electrolyte between the positive and the negative electrode by causing each mat body to be penetrated by the convex areas of a synthetic resin base body before they are squashed so as to fix the mat body to the plate body. CONSTITUTION:Concave and convex areas 9 are formed on the front and the back surfaces of a...

Between 0.001 and 0.5% by weight of polytetrafluoroethylene powder is incorporated in the composite electrochemically active mass carried on the lead plates of a lead-acid storage battery. In the case of the positive electrodes, the result is to lengthen the service life in terms of cycles of charging and discharging. In the case of the negative electrodes, the effect is to raise the low-current y...

In a preferred embodiment, for a method of extracting crab meat from the under-shell once the top shell is removed and after washing, the meat-containing under-shell is fed into the bite of pincher rolls after first adjusting the parallel axes of the pincher rolls to an angle of about 75 degrees as measured from a horizontal, and as the meat is thereby squeezed-out in a direction forward of the pi...

An automatic guidance device for a self-powered cargo-moving vehicle operated by a vehicle-borne sensor which follows a buried, energized wire path and which includes sensor means mounted either between the fixed and steerable axles or in the front of the fixed axle of the vehicle for guiding the vehicle when it travels in a direction such that the fixed axle precedes the sensor by effectively gen...

PURPOSE:To find eecution of wrong instruction by writing a specific code in a specific address of a memory chip and by executing interruption processing when the specific code is read out at the time of runaway of a program. CONSTITUTION:When a memory chip 5 is reset and initialized, a specific code is written in a specific address of respective memory chips 51-5n from a fixed data writing circuit...

PURPOSE:To detect a transfer control error at every unit of the minimum number of issues of transfer demands by dividing continuous transfer demand strings, by issuing a signal by certain number unit ancillary to the demand, and comparing the signal with a signal generated separately. CONSTITUTION:A data transfer controller 1 is composed of a transfer demand issue part 5 issuing a transfer demand ...

PURPOSE:To reduce a load of a CPU at the time of repeating and to modify a transfer system without changing contents of a main memory by providing a message repeating part, a data repeating part, etc. in a connecting device between computers. CONSTITUTION:When messages and data are transfered between computers in terms of a computer system consisting of plural computers, a message repeating part 1...

PURPOSE:To enable appropriate detection of abnormality and make it unnecessary to provide an abnormality detection circuit in each unit by programed monitoring of all microcomputer units on a common bus connection each other. CONSTITUTION:Respective microcomputer units 2 and 3 reset monitoring flags FL1, FL2 and FL3 assigned on the units themselves at the prescribed period, for instance, at a peri...

Hinged to a mounting are, on the one hand, a lever pivoting about a first axis and, on the other hand, a boot-removing lever pivoting about a second axis. The lever carries a roller cooperating with a ramp on the jaw, for the purpose of keeping the jaw in the closed position. A resilient element, applying traction, is located between two points of attachment on the lever and the jaw. The present b...

TIRE AND METHOD OF APPLYING SEALANT A continuous strip (30) of puncture sealing material is applied to an inside surface of a tire (10) by laying and adhering a plurality of side-by-side turns of the strip (30) with the different turns (32,42,54,70) connected by angular crossing portions (38,48,58) in the area of a first circumferential position (36) of the tire (10). The first crossing portion (3...

A carboxylic acid or carboxylate is reacted with an isocyanate to produce gas which is used to give a blowing action in the manufacture of a foam plastics material, especially foam polyurethane. Preferably formic acid or a formate is used.

In a process for producing fiber-reinforced hydraulically setting extruding materials, the process which comprises, not adding the reinforcing fiber in the form of single fibers to the starting materials, but employing it as collected yarns by collecting the single fibers with a collecting agent, uniformly dispersing them in the starting materials, then releasing the collected condition of said di...

A process for the manufacture of glass fiber-reinforced polyester products is disclosed. A ready-to-mold resin and reinforcement composite is prepared using an initiator which has been microencapsulated in order to prevent initiator-induced cross-linking of the resin reactants. The initiator is released during the molding of the composite by rupture of the microcapsules due to internal vapor press...
