Title: Fractionation of biologically active extracts - obtd. by vacuum vapour extraction of tissue
Inventor: THEURER KARL DR MED
IPC: A61K35/48
Filed: 1975-10-16
Abstract: Process for treating aq. or lipid-soluble extracts obtd. by vacuum vapour extn. of powdered biological tissue (pref. with H2SO4, HOAc, HCOOH or Et2NH), comprises fractionating the extracts by known methods to isolate fractions with different mol. wts., sizes or configurations. The starting material is pref. an extract of the isolated maternal or foetal part of the placenta ndecidua, chorion or trophoblast). Fractionation can be effected by sedimentation, chromatography, electrophoresis, or mol. sieve or ion-exchanger treatment, or a combination thereof. Process can be used to increase the biological and therapeutic activity of the extracts (esp. placental extracts) by eliminating inhibitory factors or enriching the active components.

Title: Reciprocating electric motor with crank drive - has fixed magnet and moving coil with power supplied only on alternate strokes
Inventor: WEINBERGER ALFRED
IPC: H02K7/065
Filed: 1976-01-03
Abstract: The reciprocating electric motor has a crank drive with power supplied only on alternate strokes. The active parts comprise a fixed magnet at one end of the solenoid and a moving coil. The coil is attached to the crank by a connecting rod in suitable bearings in a manner analogous to an internal combustion engine. The coil is energised and reacts against the magnet driving the connecting rod down and turning the crank. At bdc the coil is switched off and inertia carries the crank forward until the attraction of the magnet pulls the coil assembly back to the tdc thus completing the revolution. The sequence is then repeated.

Patent DE-2613157-A1 (DE)
Title: Corrugated roof tile insulating layer applicator - has wheeled carriage applying adhesive, plastics films and foamed plastics
Inventor: HOHLA JOHANNES DIPL ING
IPC: B32B3/28
Filed: 1976-03-27
Abstract: A flat head and sound insulating layer of plastics foam is applied to corrugated sheet made of asbestos cement, plastics, etc. so as to rest across the crests of the corrugations. This is applied by a wheeled carriage travelling on rails (2) positioned each side of a raised area supporting the sheets so as to straddle the sheets. Support members (21) are placed inside the troughs of the corrugations and removed after the application of the layer. The creasts of the corrugations are first adhesive coated, then a plastics film is applied immediately before the foam material is deposited. Finally another plastics film can be added to form a sandwich layer. The rolls of plastics film (18, 20) can be in sets, with support wheels (19) between, travelling on the crests. Viewed in the direction of travel, the foam distributor nozzle (17) can be positioned between two rolls.

Title: Plastics window frame with hollow metal core - is of low density foamed plastic under non-porous thermoplastic skin
Inventor: BRUER MANFRED
IPC: B29C48/12
Filed: 1976-04-07
Abstract: The window frame, of metal cored-foam, uses low-density insulating foam covered by a thin skin of non-porous extrudable thermpolastic. It i made by injecting the foam between the core and the skin, at the time the skin is being extruded. In contrast to known metal-cored frames which use foam as a structural material and have no covering skin, the new frame uses less material and can be made in bright, fadeless colours.

Title: Self adjusting handbrake control for disc brake - has compensating vol. between brake piston and handbrake input piston
Inventor: FARROW MICHAEL
IPC: F16D65/74
Filed: 1976-04-17
Abstract: The handbrake connection (20) for the disc brake has an input piston (16) which presses against the brake activating piston (14). The space between the two pistons is connected to the brake line (11) by a compensating duct which is closed off as soon as the input piston moves. This provides a constant travel for the handbrake linkage with pad wear. No mechanical adjustment is required for the handbrake linkage. The hydraulic compensating control is fully automatic with the duct opened when the handbrake is released, and the input piston is moved back by a spring.

Title: Pipelines reinforced by wrapping with steel strips - has wrapping tension equalised to avoid pipe distortion by simultaneous winding of two spaced sections
IPC: B65H81/08
Filed: 1976-10-11
Abstract: Several strips, or wires, are wrapped round a long cylindrical body, such as, a pipe. The winding is simultaneously undertaken in opposite directions in two spaced zones. Thus, at least two strips or wires, are wrapped in each zone, so that the resulting tension forces are zero. In each zone, the strips, or wires, are pref. applied in pairs at diametrically opposed locations, the two wires in each pair being exposed to the same tension. The wrapping can be carried out on site, e.g. immersed pipes can be butt welded together on a pontoon and then wrapped continuously. Due to the balanced tension forces, the risk of pipe distortion during wrapping is eliminated and it is no longer necessary to hold the pipes in a jig.

Title: Vehicle wheel fitting acting as snow chains - has arms fitting over tyre tread and tensioned by screw on mounting hub
Inventor: MONTEIL YVES PHILLIPE EMILE
IPC: B60C27/02
Filed: 1976-10-14
Abstract: A device having the same purpose as snow chains for the wheel of a vehicle, but which is easily and quickly fitted, has a set of e.g. three arms which hook over the tread of the tyre. These arms are attached to a cross shaped member which fits against the wheel hub. At the centre of the cross shaped member is a locking screw which engages a locking nut connected to the attachments of the arms. Each arm has a hinge so that it can be swung over the tyre, and at the hinge point is secured a rod with a block at the end. This block has a sloping surface which engages a sloping slot on the nut, so that when the screw through the nut is rotated, the sliding action tensions the arms and locks them.

Title: Water-tight communication cable prodn. - involves application of sealing material to cable core in pressure chamber fed by pump
Inventor: KLEBL WOLFRAM DIPL ING
IPC: H01B13/22
Filed: 1977-05-20
Abstract: Cables have plastics insulated wires, with hollows in the cable core filled with a sealing material well adhering to the wire insulation and to the sheath surrounding the core. A pressure chamber is used for application of the sealing material to the finished cable core, with the material pressed into and around it. The material is held in a vessel in a highly viscous state and under pressure by a pressure plate, so that it is pressed out from the vessel. The sealing material (2) is extracted from the vessel (1) by a pressure generating pump (5) driven by a speed controlled electric motor (6) and mounted in a hole of the pressure plate (3). Pressure inside the pressure chamber (8) is continuously measured by a device (11) delivering a pressure dependent voltage compared in a controller with a normal value. In case of a difference the speed of the motor connected to the controller is corrected.

Title: Liq. premix for slurry explosive - made by reacting formaldehyde and ammonium nitrate in presence of reducing salt
Inventor: VARADACHAR KUPPAM SRINIVASA
IPC: C06B21/00
Filed: 1977-05-27
Abstract: A lig.-phase premix of oxidiser, sensitiser and fuel is made by first warming together NH4NO3, HCHO and reducing salts (e.g. formates or sulphites so as to increase the formation of a mixt. of amine nitrate sensitiser and fuel without producing hexamethylenetetramine. The mixt. is kept at 95-105 degrees C. for 2-3 hr. and the water content after neutralisation is reduced to is approx. 12%. The premix can then be processed to a slurry explosive by blending with NaClO4, S, graphite, water, vegetable gum and cross-linking agent and passing air through until the density is reduced to 1.05-1.10 g/cc. The reducing salt suppresses formation of formic acid (so reduces amt. of alkali needed for neutralisation) and increases yield of amine nitrate mixt.

Abstract: The staircase step incorporates a load bearing piece in the form of a metal frame with a core of cement-bonded material filling its interior: a covering is attachable at least to one side face and/or to a top surface and there are also media for joining several step pieces to a staircases as in 2713480. These media comprise one or more metal fishplates (19). One end of these is attachable to a lengthways side (4, 5) of the metal frame (1) running in the direction of step depth, and the other end to the corresponding lengthways side of the metal frame on an adjacent step, pref. on the outside, by means of a protruding bolt (20). The bolt may serve to hold a side cladding. This provides a simple method of joining adjacent steps together to form a partially or wholly free-standing staircase.
