Title: Semi-conductor device internal connection equipment - has inductance connected to collector and switch to produce pulse at base
Inventor: PARMENTIER PAUL
IPC: H01L23/525
Filed: 1975-09-18
Abstract: Internal connections are made at selected points of semi-conductor elements. The process used avoids non-negligible impedance at the point of connection. The connections are direct and do not require high intensity current and consequential dimensioning of the circuit. The internal connection can be between two points (24,25) of an element, of an integrated circuit. An inductance (21) is placed in series with the collector of the transistor (20). The inductance (21) is supplied by a positive voltage (+V). The base of the transistor (20) is excited by pulse which takes from a base polarisation voltage (e1) to a blocking voltage (e2). An induced voltage is produced at the terminals of the transistor (20) and it results in secondary breakdown. A short-circuit (23) is then produced between emitter and collector connected to the two points (24,25).

Title: Explosive shear for borehole tubes of boring bars - uses two liquids not explosive until mixed and easily obtainable
IPC: F42B3/00
Filed: 1976-01-26
Abstract: An explosive device, esp. for cutting borehole pipes and boring bars, has, inside a housing, a piston which delimits a sealed chamber for an explosive. The piston is of a floating type and divides the housing into the explosive chamber and a compensation chamber which is filled with gas under pressure. A cone is provided in the explosion chamber as an integral part of the floating piston. Explosive devices of this type are used to cut tubes and other items when they become locked in the hole. Owing to the great heat and high press. encountered, it is often dangerous and sometimes impossible to use explosives in deep holes. The explosive used at present is in the 'A' class which has to be stocked and transported according to strict rules. This often makes it impossible to convey an explosive to a site and to carry out a task within a limited period of time. The difficulty is remedied by an explosive liq. which is transportable by air, since its two constituents, cannot be detonated until they are mixed.

Title: Safety glass made by bending two panes - simultaneously cut to their respective sizes before assembly and bending
Inventor: SCHREYER HEINZ
IPC: C03B33/04
Filed: 1977-01-25
Abstract: Panes employed in mfg. bent multilayer safety glass are cut to their different peripheral shapes prior to assembly and bending to form one pane. The novelty is that the panes (e.g. two) are simultaneously cut to their respective sizes using separate cutting tools. The pref. cutting plant uses only one template scanned by an x-y coordinate controller driving two slides, each fitted with a cutter. The first slide cuts one pane to the size of the template, but the second slide is fitted with two servomotors programmed so the second pane is cut to a larger size. The second pane has a larger bending radius so that after assembly and bending both are the same length and form one pane of safety glass.
