Title: Detachable fixing for disc brake linings - has threaded bolt fixed to pad and held to carrier by nut
Inventor: BARONNET PIERRE
IPC: F16D65/092
Filed: 1974-11-25
Abstract: The design is for disc brakes on heavy vehicles. The brake pad has at least one threaded bolt on its reverse side. This projects through a hole in the support plate and is secured by a nut. The advantage claimed is speedy removal of an old lining even after prolonged use. The bore in the support carrier (4) has greater diameter than the fixing nut (9) but there is a support disc (10) between the pad and the carrier which has greater diameter than the bore. The disc has radial slots (11); two opposed wedge shaped notches and is made of two half shells or two V shaped plates. The stud is fixed to the brake lining by a small raised section (18) that has the same diameter as the hole.

Title: Electronic wrist watch - has miniature battery charged via gravity weight driving generator
Inventor: LENNARTZ ALOIS PROF DIPL ING
IPC: G04C10/00
Filed: 1975-01-17
Abstract: The electronic wrist watch includes a gravity weight (S) which drives a generator (G), used for charging the miniature battery (B) via a forming circuit (F), the latter preferably incorporating dual rectifying means. The weight (S) oscillates so that the generator (G) is driven in both directions, thus providing an alternating voltage, rectified via the forming circuit, which pref. provides an output voltage with a higher working gradient and also prevents the reverse flow of charge to stop any battery discharge. Pref. a mechanical energy store, e.g. a spring system is positioned between the weight (S) and the generator (G).

Title: Three-phase inverter assembly continuous switching - uses monitors between each inverter and its magnetic voltage stabiliser and output monitors
Inventor: FELDMAIR LEONHARD
IPC: H02J9/06
Filed: 1975-02-01
Abstract: The inverter assembly consists of three inverters and each of the three inverters is followed by a magnetic voltage stabiliser. A first type of monitoring circuit is inserted between each inverter and its corresponding voltage stabiliser, and a second type of monitoring circuit is inserted in each phase at the three-phase inverter output. All monitoring circuits are connected to a control circuit which holds a contactor closed in absence of an alarm signal from one of the six monitoring circuits. When the alarm signal from one of these circuits appears, it opens the contactor and at the same time closes electronic switches connecting the load to the three-phase mains.

Title: Failsafe monitor network for railway use - monitors two logically inverse channels with failure signal if fault in channel state detector
Inventor: LOTZ ALFRED ING GRAD
IPC: H03K19/21
Filed: 1975-10-02
Abstract: The network monitors two logically inverse channels. A voltage divider followed by a diode bridge circuit controls a blocking oscillator with feedback loop which produces an AC signal in a secondary feedback loop if the channel signals are inverse. An additional circuit ensures the continuation of the AC signal of the inverse condition is not disturbed for longer than a preset time. The circuit is composed of failsafe elements. An external condenser determines the time delay of a circuit with adjustable signal, decay time and minimum switch-on time. The signal decay resets a store and blocks and AND-gate for transmission of the monitor network input passed through a threshold circuit. The store must be set at the beginning of the monitor cycle.

Title: Walking beam furnace - esp. for heating small dia. rods, bars etc. without distortion
Inventor: HATZENBICHLER ERNST
IPC: F27D3/02
Filed: 1975-12-17
Abstract: A walking-beam furnace esp. of the type which is charged and unloaded from the side is described. The refractory load support, which extends over the entire length of the furnace, consists of fixed and moving beams. The furnace is heated from above and below by burners. The load support consists of integrated components of the beams of refractory materials. The furnace is heated from below only in the preheat zone. In the high temp. part of the furnace the load-supporting faces of the beams have such a width that the space between the beams is only sufficient to permit the movement of the beam. The absence of water cooled beams made possible by placing the beams closer together leads to high thermal efficiency. Small dia. bars can be heated without distortion since they are uniformly supported over their entire length.

Title: Coal gasification plant - having radiant tube flue with hydraulic and thermal cleaning preceding waste heat recovery
IPC: C10J3/84
Filed: 1976-03-20
Abstract: In a coal gasification plant, operating at >900 degrees C the synthesis gas is cooled down in a waste heat recovery plant. The latter is preceded by a radiant tube flue with a hydraulic and thermal cleaning system which ca be lifted in and out of a water bath. This solidifies the slog in the radiant tube flue and prevents clogging of the following convection heating surfaces. The continuous cleaning of the flue prevents any undue rise of the upstream gas temp.

Title: Clamp for aligning and holding two pipe sections - positions pipes for internal welding by rotating laser beam
Inventor: QUARTLEY CJARLES PENRUDDOCKE
IPC: B23K26/282
Filed: 1977-02-24
Abstract: An internal clamp for holding securely the adjacent ends of two pipe sections or similar hollow details which are to be welded together, is applicable on land or on pipe-laying ships with laser welding devices. It has two supporting cylinders, each of which can be inserted in one of the pipe ends. Each supporting cylinder has outwardly expandable clamps. A hollow arbor carries the supporting cylinders, which are spaced some distance apart. The arbor is free to rotate relatively to the cylinders and has a window in line with the space between he clamp support cylinders, so that a laser beam can be projected through it and form a complete internal joint whilst the arbor turns through 360 degrees. The clamp can hold two adjacent pipe sections and if necessary bring them into contact. At the same time it has sufficient power to expand both sections to the same dimension and alignment so that a good welded joint can be made.

Title: Screw extruder for mfr. of mouldings with marble-like pattern - having a short screw in inlet zone to prevent thorough mixing of the dissimilarly coloured components
Inventor: HAEDRICH FRIEDHELM
IPC: B29C48/03
Filed: 1977-04-01
Abstract: Extruder comprises a heated barrel with a short, single-zone screw in the inlet section for the moulding cpd. Adjacent there is, in the heated zone of the barrel, a displacement body over which the plasticised moulding cpd. is conveyed to the die orifice. The screw, being short and located only in the inlet zone serves only as a plasticising screw so that thorough mixing of the dissimilarly coloured moulding cpds., which would destroy formation of a marble pattern, is prevented. This is further facilitated by the displacement body which also reduces mixing action of the screw.
