Patent DE-2844180-A1 (DE)
Title: Automatic fire extinguishing equipment - uses chemical action liquid inhibitor in thermoplastic capsules released by heat from igniter elements
Inventor: KLIMENKO ALEKSANDR SERGEEVITSC
IPC: A62C35/08
Filed: 1978-10-10
Abstract: The fire extinguishing equipment consists of a vessel filled with fire-stifling material. The material consists of liquid Freon (RTM) enclosed in microcapsules of a thermoplastic material, such as gelatine. The vessel is firmly closed by a cover, while the rest of the vessel surface is provided with a great number of perforations. The vessel is mounted with the lid parallel either with the room wall, or the room ceiling, the perforation pointing into the room. The vessel surface has an extended spherical part fitted with several igniters consisting of a pyrotechnical mixture which ignites at a certain temp. in the room. The igniter sets off a charge contained in a perforated cartridge which developes the heat necessary to melt the gelatine cover of the liquid Freon, which then evaporates and enters the room via perforations.

Title: Flexible laser beam guide for medical use - has fibre fitted copper or brass block with polished reflective outer surface
Inventor: FRANK FRANK DIPL PHYS
IPC: B23K26/02
Filed: 1978-12-12
Abstract: The flexible light guide for a laser beam is suitable for medical use. The light guide fibre is enclosed by a sleeve which terminates short of its end. This end is enclosed by a centering sleeve of copper or brass, having a high heat conductivity. Mounted on the outside surface at this end is a reflective layer. This sleeve and the enclosed fibre are in turn enclosed by an outer sleeve of e.g. aluminium. The inner sleeve tapers down to a section of reduced diameter. This leaves a clearance space inside the outer sleeve, leaving room for a ring clamping the reduced diameter part onto the fibre. The end of the fibre and the reflective layer are polished.

Title: Vibration damping for vehicle gear lever linkage - has angled coupling plates with sandwiched elastic layers separating sections of gear selector shaft
Inventor: PAUSE ROLAND ING GRAD
IPC: F16H59/04
Filed: 1978-12-20

Title: Adsorption vessel for sepg. gases and vapours - where vessel wall consists of polymer reinforced by glass fibres and provided with polymer lining resisting corrosion
Inventor: BECK ROLF
IPC: B01D53/04
Filed: 1979-10-04
Abstract: Parent patent described a plant contg. a stationary adsorbent, esp. active carbon, employed to remove the vapour of a volatile solvent from air, followed by using steam to regenerate the adsorbent. The plant consisted of a vessel contg. an inlet chamber (2); an adsorbent chamber (1); and an exit chamber (3).

Title: Hydrolysis of starch in farm produce - using process water preheated under pressure
IPC: C13K1/06
Filed: 1979-10-13
Abstract: Hydrolytic degradation of starch in form produce (A) comprises mixing individual batches of (A), as a mash, in a hydrolysis vessel with warm process water, heating the mash to 135-170 deg.C and maintaining this temp. for the required time. The water is 0.8-1.6 times the wt. of (A) and is heated under pressure to about process temp. (A) is first filled into the vessel then, while maintaining a vortex, the water introduced sufficiently quickly to (practically) prevent glutinisation of (A). Pref. (A) is (nearly) dry and the water is heated to above the process temp., esp. about 190 deg.C. The heat demands of the process are reduced since only about half as much water (compared with the usual process) needs to be used. The hydrolysis prod. is 'thin' enough to be transported through pipes.

Title: Decoration of ceramic mouldings such as tiles - where flat spirals of wire are used to transfer glaze films onto mouldings
IPC: C04B41/81
Filed: 1980-02-08
Abstract: A flat wire pattern or spiral (15) is lowered into a tank contg. a decoration liq. (2), and is then lifted so a film of liq. (2) remains on the spiral (15). The spiral is next lowered so it touches the surface of a ceramic moulding (5) and is then raised, leaving the film of liq. (2) on moulding (5). Liq. (2) is pref. a pigment soln.; a glaze; or a glue onto which a decorative powder can be sprayed. The pref. plant consists of a carrier (8) which can be driven vertically, and contains several plungers (13), which each carry a spiral (15). After being dipped in liq.

Patent DE-3007729-A1 (DE)
Title: Current operated stimulator for medical use - with bifilar wound transducer and feedback signal from primary winding
Inventor: JOCHEMCZYK CLAUS
IPC: H01F27/42
Filed: 1980-02-29
Abstract: Current operated stimulators require approximately constant current in the output electrode (Z) which is susceptible to large variations in resistance. These may be caused for example by contact resistance, method of electrode mounting or attachment and similar effects. Feedback signals from the electrode circuit can be phase sensitive, and can change from negative to positive. The transducer (11) between the controlling amplifier (10) and electrode (Z) has bifilar wound primary and secondary windings. The resulting inductance balance and low leakage allows the use of a current measuring resistor (12) in the primary circuit to provide the stabilising feedback to the amplifier for regulating the primary loop current. The primary and secondary windings have the same effective wire length. After a set number of turns the primary wire is looped out to form a series of subwindings which are then connected in parallel to the amplifier. The secondary winding has all conductors in series. The arrangement reduces the leakage flux and thus the phase shift between the windings.

Title: Voltage supply circuit for TV receiver picture tube - has voltage divider producing variable focussing volts and screen-grid volts
Inventor: PETRICK PAUL DR
IPC: H03H7/24
Filed: 1980-03-10
Abstract: The voltage divider is connected to the output of the high- voltage cascade comprising diodes and capacitors. The voltage divider (2) consists of a series chain of resistors, two of which are variable potentiometers.

The number of resistors -- both variable and fixed -- in the voltage divider may vary according to requirements. The voltage divider is simple and cheap- (The screen-grid voltage does not need to be derived from the secondary side of the line transformer).

Title: Warp-tension compensating device for hand-loom - moves backrest towards breast-beam as shed opens
Inventor: LUKOW KOITSCHO
IPC: D03D29/00
Filed: 1980-04-08
Abstract: A loom, partic. a hand-loom with a roller-suspension system for counter-moving heald shafts producing plain weave, has eccentrics on either end of the suspension roller which are so connected to the warp back-rest that when the shed opends the back-rest is drawn towards the breast-beam sufficiently to counteract the increase in warp tension due to the deflection of the yarns. This reduces the shedding force for wide shed openings, and enables the distance between breast-beam and back-rest to be reduced, giving a very compact loom construction.
