Title: Hydraulic vehicle disc brake - tubular piston formed by two ring elements each with square sealing ring
Inventor: KLAUE HERMANN DR ING
IPC: B60T1/06
Filed: 1974-08-28
Abstract: The brake lining housing (4, 5) is bolted to the wheel hub (6). Between the two lining faces the brake piston carrier (12) is fitted with brake rings (11) sliding on the linings during braking. The tubular piston (14), fitted in a circular groove of the piston carrier is sealed from outside by square section sealing rings (15, 16). The piston carrier floats axially, so that when the piston emerges from the ring cylinder, the pressure on one side of the piston on the brake ring and the lining results in equal reaction pressure on the opposite side of the piston carrier. Pressurised brake fluid is supplied through the hose (19) and channel (20) to the rear face of the ring piston.

Title: Switch operated through secondary clock line - used e.g. for delivery of time break signal in school
Inventor: SCHILLINGER MAX
IPC: G04C21/30
Filed: 1974-09-06
Abstract: The switch comprises a signal switching device controlled by pulses on the secondary clock line and a locally excited switching device timer. A capacitor (C1) can be connected to the clock line by the signal switching device. A bistable store (R) operating as the signal switch, is controlled by the capacitor (C1) charging current, and can be operated without supply voltage. A timing circuit controlled by this capacitor (C1) operates a discharge switch (S) for the capacitor, thus resetting the bistable store (R). The capacitor (C1) is charged via the rectifier bridge (B) and the pre-resistor (W1). This causes a current to flow through the polarised relay (R) to bring it from the rest to the working state where it remains until released.

Title: Indictive element for film ccts. with low stray field - has two flat coils coupled in series opposition
Inventor: RABL HELMUT DIPL ING
IPC: H01F27/34
Filed: 1974-09-30
Abstract: The functioning element is intended as a concentrated inductance for both thick and thin-film circuits has a low stray field and a slight parasitic parallel capacitance. It is preferably in the form of a flat coil with spiral conductive paths. Typically it is formed by two identical flat coils connected in series opposition. The two flat coils preferably meet specified relations based on each coil outer diameter, and number of turns in each flat coil. The low parasitic parallel capacitance is especially suitable for choke coils. The bearing of the flat coils, however, makes the arrangement also suitable for oscillator circuit coils.

Title: Continuous jointless concrete floor laying - using permanent concrete-bonding alignment battens joined to base anchored supports
Inventor: ZEITLER OTTO
IPC: E04F15/14
Filed: 1974-10-12
Abstract: The process is designed for laying continuous concrete floors, with no joint seams showing, in spite of precautions taken for expansion in hardening and due to temperature effects, which can lead to fissure formation. The alignment battens (6) inserted at intervals, for the vibrator mechanism (4) or other device led over them, for a bonded seal with the floor surface, and are firmly joined to vertical supports (5) anchored in the substructure (1). The battens may be made of metal, with a corrosion-resistant coating at least in the area of their open surface. This can be in the form of a plastic matching the colour of the hard-set concrete; and the battens may be galvanised. They may be welded to the vertical supports. There may be reinforcing battens running across them.

Title: Drawing off and cooling a synthetic extrusion - esp. a calibrated flat film, through water with laminar flow
Inventor: RAHLFS HERBERT
IPC: B29C48/08
Filed: 1974-12-04
Abstract: An installation for drawing off and cooling a synthetic extrusion, has the slot nozzle laid out for a flat film, and the breadth of the cooling shaft corresponds to that of the slot nozzle. The depth of the cooling shaft and the pitch of its walls together with the feed of the cooling water, are arranged so that in funnel shaped inlet of the shaft, a wedge of cooling water builds up, and a laminar flow takes place in the shaft. Below, the guide roller around which the film turns to be drawn away, is positioned so that the point of impact of the film is central to the plane of the cooling shaft. Makes it possible to draw calibrated films with a high degree of accuracy at fast speeds from a slot nozzle.

Title: Fully automatic sorting device for cable sheath or metallic article - has field coil through which article passes, linked to oscillator and signal circuitry to determine article destination
Inventor: KAEFERLEIN CHRISTIAN
IPC: B07C5/344
Filed: 1974-12-23
Abstract: A system for fully automatic sorting of cable outer jackets or metallic small articles is constructed such that a field coil through which a sample piece passes alters the frequency of an oscillator. The transmittance frequency passes a filter stage attached behind the oscillator and produces a trigger impulse which controls a sorting device. This sorting device can then prepare the path along which the test piece passes by means of electronic signals to ensure that the sample or test piece arrives at its appropriate destination.
Patent DE-2461966-A1 (DE)
Title: Casting concrete in tubular offshore construction supporting legs - water expelled by compressed air before filling
Inventor: BASSETT MAX
IPC: E02B17/00
Filed: 1974-12-31
Abstract: A concrete reinforcement is cast into an offshore construction support leg standing vertically, and comprising a tubular mantle with >=1 stiffening pile, the o.d. of which is smaller than the i.d. of the mantle, so that a cavity is formed, sealed at the top and open at the bottom where it rests on the sea bed. At the start of the operation, the bottom zone contains mud which is washed out by pumping, before the water itself is expelled by compressed air. Whilst a pressure of air sufficient to keep out the water is maintained, the fluid concrete is pumped in and allowed to set. Depending upon the nature of the terrain, some of the concrete may be allowed to spread around the foot of the support, as to form an anchorage block. Or the first charge may be hardened under air pressure so that the bottom end of the cavity is plugged. Top loading dispenses with the need for divers. Water and sludge are expelled from the tube so that thinning down of the concrete causing hardening difficulties, and losses of material through the bottom end of the tube are avoided.

Title: Conversion of gaseous hydrocarbons and gas oil into aromatics - and isobutane with a faujasite catalyst in a single riser reactor
Inventor: OWEN HARTLEY
IPC: C10G11/05
Filed: 1975-01-24
Abstract: The conversion of C3/C4 hydrocarbons and higher-boiling hydrocarbon fractions into aromatics-rich products and isobutane is carried out by (a) passing a suspension of a hot regenerated faujasite catalyst in a C3/C4 gaseous hydrocarbon stream at ca. 1250 degrees F through a lower annular portion of a riser reactor for a residence time of 0.1-2 sec.; (b) introducing a higher-boiling hydrocarbon fraction (gas oil or higher) into the suspension at one or more points downstream from the annular zone; (c) passing the suspension through the riser reactor at 900-1000 degrees F for a residence time of =10 sec.; (d) separating the suspension into a hydrocarbon phase and a catalyst phase; and (e) sequentially stripping and regenerating the sepd. catalyst phase. Significant amts. of aromatics and isobutane are produced by cyclisation and H-transfer of the C3/C4 hydrocarbons introduced and those formed by cracking of the heavy hydrocarbon.

Title: Extractor ion source with cylindrical anode cage - has grid between wire cathode and anode cage to give linear profile
Inventor: POLASCHEGG HANS-DIETRICH DR
IPC: H01J27/02
Filed: 1975-03-07
Abstract: The extractor ion source consists of a cylindrical anode cage open at one side to admit injected electrons, and a wire, tape or helical cathode.
