Patent DE-2629054-A1 (DE)
Title: Gas blast circuit breaker - is of small overall dimensions and has slot acting as valve between cylinder and piston
Inventor: RAPP GUENTER
IPC: H01H33/915
Filed: 1976-06-29
Abstract: The circuit breaker uses a quenching gas for arc control. It compresses the gas with ring piston of an annular cylinder where the precompression period takes place during the first part of the piston stroke. The arc between the separate contacts is then extinguished by the sudden blast of the quenching gas. During the switching off operation, the movable contact (16) moves down together with the nozzle (17) as well as the annular compression cylinder (3, 4) for the quenching gas. At the same time, the ring piston (2) remains stationary, and the gas held in the pump chamber (1) is gradually compressed. When the bores (10) of the piston (2) align with ring groove (9) of the cylinder, the quenching gas starts flowing two channel (18) of the nozzle via holes (6) to provide the blast for extinguishing the arc between the contacts.

Title: Connector with threaded metal bush for plastic pipes - holding pipe securely by penetration of outer thread turns
Inventor: SCHMALZIGAUG OTTO
IPC: F16L47/20
Filed: 1976-09-23
Abstract: Connector for pipes made of polyethylene, polypropylene or similar plastics comprises a fitting inside the bore of which is a conical metal bush with an internal thread of which the turns are pointed at the larger-dia. end and flattened at the smaller dia. end. The bush is pref. located remotely from the point of entry of the fitting, thus forming a cylindrical shank of a given length which transfers the zone of bending of the pipe relative to the inlet of the thread of the bush.

Title: Metallic resistance layer for explosive primer - has alloy layer on auxiliary carrier produced by physical or chemical process
Inventor: KRAUS HEINZ
IPC: F42B3/198
Filed: 1977-01-14
Abstract: The method serves for producing metallic resistance layer for the manufacture of primers. The method uses either a pliable or rigid auxiliary carrier sheet. The auxiliary carrier sheet (H) is usually a thin chronium steel sheet with one surface polished and chemically treated in such a manner that the layer (W) of metallic resistance alloy does not adhere very much onto the surface. The layer consists of several intermediate layers of different alloys applied by galvanic methods. Subsequently the layer undergoes an after treatment by tempering and doping to ensure the reproducible specific resistance. The carrier together with the treated layer can be transferred onto the insulating body of duroplast with glass fibre reinforcement by a thermoplastic adhesive layer. The other surface of the insulating body is provided with a thin copper coating to provide a conductor surface.

Title: Depositing high purity silicon onto three silicon rods - each heated by one phase of a three phase mains supply
Inventor: BAROWSKI GERHARD ING GRAD
IPC: G05F1/455
Filed: 1977-01-31
Abstract: The parent patent described the deposition of high purity Si(HPS) from a reaction gas onto HPS rod substrates, where e.g. three substrates are each connected to a pair of electrodes in a single common reactor. Each pair of electrodes is connected to the sec. of a transformer; and the prim. winding of each of the three transformers is fed by one phase of a three phase mains supply. In this addn. the output impedance of the three transformers (M1, M2, M3) stabilises the heating current so the three substrates (T1,T2,T3) are between he min. deposition temp. (tmin) and the desired deposition temp. (td). The three transformers pref. have high leakage reactance; and when the sec. is short-circuited, the prim. current is 3-5 times the nominal value; the transformers pref. have an overload factor of 10. The three substrates can be uniformly heated without any switching operations.

The arrangement is such that the two lateral strips engage members (9) of the rear of the distribution element, when the bracket is pressed in, thus the bracket is held in place. The plate has preferably a bolt engaging a bore in the rear member (9).

Title: Buttress wall anchoring for soft ground - using borehole filled with pressurised foam which is delivered through drill rod to support hole walls and flush away cuttings
Inventor: PANZER FERDINAND
IPC: E21B21/08
Filed: 1977-05-13
Abstract: the borehole (3), drilled through the concrete buttress wall (1) into the loose ground (2) by the drill bit (4), is cased over the distance (a) by a tube (12) with packers (14). Liquid foam is pumped through the hollow drill rods and couplings (9) to the borehole bottom (5) through holes (7) and back to a restrictor valve (22). By introducing a pressurised medium (25) through the hose (26), the elastic tube (23) can be compressed to keep the pressure near the outlet (18) to 0.5 - 2 atmosphere gauge. The diameter of the drill rods is brought up to that of the bit shank (8) and couplings (9) by pushed-over tubes (21) so that the lip seals (20) are fully effective.

Title: Operational test of process control computer data channels - involves individual switching of channels during on=line operation
Inventor: KRUEGER AXEL
IPC: G06F19/00
Filed: 1977-07-19
Abstract: A device performs operational tests of data channels between a process computer and the external signal sources and receivers of an operating system controlled by the computer. The system may be used in a cement factory, and is designed to enable on-line testing of individual channels without affecting the remaining channels. The data channels consist of electrical conductors enabling two-way data signal transfer via interface cards. Each data channel can be separately switched from on-line operation and into connection with a simulator signal generator. A test instrument for each conductor enables indication of the signal coming from the operating system on the computer both for on-line and test mode.
Patent DE-2734757-A1 (DE)
Title: Prestressed concrete beam mfr. - uses threaded steel bars inserted into sheaths joined to screwed sleeves to reduce prestress at supports
Inventor: BIRGUER ALEXANDRE DIPL ING
IPC: E04C3/26
Filed: 1977-08-02
Abstract: The prestressed concrete beam manufacturing process uses threaded reinforcing bars, quality 85/105, and of 26.5, 32 and 36 mm diameter. The bars can be anchored by adhesion between steel and concrete, and steel plates can be secured to them by nuts to give increased adhesion. The amount of prestress can be reduced near the supports, by insertion of a section of the threaded bar into a sheath joining onto a screwed sleeve. This section can be unscrewed and withdrawn from the beam. The reinforcing components can be arranged to suit the bending moment diagram, and also used for after-stressing.

Reaction soln. pH 6-9 is maintained up to 5-40% conversion, and is then set to 4.5-8 until condensn. is cut off, so that it lies 1-2 units below pH in 1st reaction phase. Reaction is stopped at 0-10 wt.% HCHO content, by deactivating free catalyst. The catalyst is removed; and carbonyl gps. in prod. are opt. reduced to OH gps. Novelty, according to Patent of Addn., consists in using Gp. IB metal cpds. as catalyst. The catalysts (I) simultaneously act as oxidising agents in co-catalyst prepn. Pref. catalysts are Cu or Ag cpds., esp. the sulphates, nitrates or acetates.

Title: Cut=out circuit for motor operating window or roof in vehicle - pulses motor when overload occurs and disconnects permanently after given number of pulses
Inventor: NOESKE DETLEV
IPC: H02H7/085
