An automatic injector is provided having at least two chambers (27 and 28) containing different ingredients of a medicament separated by an impermeable membrane (29). A lance (34) is movable independently of a plunger (33) to cut or pierce the membrane (29) before a spring-loaded drive member (37) for the plunger (33) is released to drive a needle (30) out of the body (1) of the injector and disch...

A separation preventive pipe joint comprises a socket and a spigot inserted into the socket with an annular packing interposed therebetween. An annular gland connected to the socket has an axial packing presser projection and is internally provided wtih an annular receptacle groove. Arcuate engaging segments are incliningly disposed in a circular arrangement within the receptacle groove and retain...

A method for raising flattened tubular blanks by rolling them out, or folding them by nearly 180 DEG and reforming them to a square-shaped cross section uses the device comprising at least two discharging rollers (1, 1') for rolling out flattened tubular blanks (C) on a rolling line, and a pusher moving mechanism (4) for pushing the blanks (C) on said rolling line first into an overfolded positio...

In the induction heating of thin (e.g. 0.5 to 3 mm diameter) steel wires (W) in continuous heating processes, relatively low field strengths of e.g. up to 20,000 Am-1 are employed but are chosen so as to set the relative magnetic permeability mu r at 40 or more. The wire are passed through coil blocks (1), which are wound flat around a row of ceramic tubes (3) to guide and insulate the wires. The...

Fault currents in the phases of a three-phase supply are detected by transformers 28 in respective phase links 14 and are counted by associated circuits 24 when any one of the circuits 24 reaches a predetermined count level, or when there is a fault condition, a low VA trip coil 42 is energized so as to release latches which hold the phase links 14 in their operative positions and thereby cause al...

An optical sensor probe (100) for emitting light into blood and detecting light reflected by the blood, having one end of a first light transmitting member (105) brought into contact with blood flowing through a conduit (101), and capable of emitting light into the blood in the conduit by introducing the light into the first light transmitting member (105) from the other end thereof. Part of the l...

Car protection intended firstly for covering a vehicle and secondly for covering a ground space. The cover sheet 4,8 of the car protection is dividable. The cover sheet 4,8 is rolled up in a folded-together manner on a reel 5,6,7 which is supported and mounted on the vehicle round about the rod 3 of a load holder 1,2.

A frame saw, which operates at high speed and is simple in its construction, comprises a set of blades which can be fitted outside the machine and which is fixed in a light frame 40 provided with a to-and-fro motion by means of a drive mechanism. The frame 40 has a guide system 10,20,5c which gives the blades an expedient motional path avoiding blade-stressing peak forces, this being ensured in th...

The invention concerns a telescopic mast comprising a number of telescopically displaceable sections 1 - 5 and means for creating such displacement, preferably consisting of a cable system 6 and members 7 for operating this system, the sections being provided with complementary internal and external control members and slide members 13, 15. The novel feature lies in the fact that, in order to allo...

A prepn. of monotertiary butyl toluenediamine from 2,6-and/or 2,4- toluenediamine and isobutylene or precursor is catalyzed by an acidic zeolite catalyst with pores of about 6-8 Angstroms. The reaction is effected pref. at 150-225oC and 50-2000 psig. The zeolite is pref. H or rare earth ion exchange.
