Title: Silicon deposition appts. - with coolant bore in base plate near quartz bell sealing ring groove for perfect tightness
Inventor: DIETZE WOLFGANG DIPL CHEM DR
IPC: C23C16/44
Filed: 1978-06-19
Abstract: An appts. for the deposition of semiconductor material (silicon) on a heated carrier from the gaseous phase includes a baseplate, made of metal (steel) with a pore-tight coating of silver on the reaction chamber side.

Patent DE-2845800-A1 (DE)
Title: Locking system for pressure cookers - automatically operates when temp. and pressure rises
Inventor: KUEHL HANS DIPL ING
IPC: A47J27/08
Filed: 1978-10-20
Abstract: The lid is locked on the edge of the cooker pan by a mechanism(105) which can be operated by an actuating element(109) which becomes distorted in dependence on the temperature. The actuating element is preferably made of a temperature responsive material which is mounted in a chamber(108) having at least one opening. Thus it expands as the temperature increases, thereby filling the opening to cause the lid to lock automatically when the temperature rises. The pressure cooker cannot be opened whilst there is still too much pressure. No special safety features are required.

Title: Thermally conducting insulating discs for electronic components - comprise ceramic inserts in plastics insulating plate, extending from surface to surface
Inventor: JESTER ALFRED DIPL ING
IPC: H01L23/373
Filed: 1978-12-22
Abstract: The object of the composite disc is to reduce the danger of damage to the semiconductor assembly, for example an integrated or printed circuit, due to differential expansion between the same and the disc. A disc or plate made of plastics insulation material is pierced by holes which are filled with a ceramic material. The regions of high differential thermal expansion at the ceramic-semiconductor interface are thereby confined to discrete small areas, thus giving low forces tending to rupture the semiconductor. The proportion of ceramic filling of the plate is pref. no less than 80%. The ceramic fillings are with advantage hexagonal in cross section. The ceramic material is typically beryllium oxide, but aluminium oxide may also be employed.

Title: Fabrics in rope form are jet-dyed in closed cycle - by using kinetic energy of fluid issuing from nozzles to feed fabrics into or through dyeing plant
Inventor: ELTZ HANS-ULRICH VON DER DIPL
IPC: D06B3/28
Filed: 1979-03-30
Abstract: Natural or synthetic fibre fabrics are jet-dyed in a closed cycle in a high pressure vessel by using the kinetic energy of fluid issuing from a nozzle or bank of nozzles to convey the fabrics in rope form into or through the dyeing plant. Energy is derived by tangential impinging of the fluid jet onto fabric relative to its direction of movement. Displacement of fabrics into or through plants which devoid of dyeing liquor or only partially filled with the liquor is possible. Dyeing periods are reduced.

Title: Multiple position monitoring system using flat cable - passes one cable of current-carrying three core cable through magnetic circuit to obtain monitoring signal
Inventor: DROSTE WERNER PROF DR ING
IPC: H04B3/54
Filed: 1979-09-08
Abstract: The monitoring system using a number of monitoring devices along a three cored flat cable, through which current is passed from a remote station, uses the two outer conductors (4.1) to form a loop through which energy is supplied from the remote station. These two conductors can be connected to the ends of a secondary coil of a transformer (11) at the remote station, and the third conductor is connected between a lapping (10) between the ends of the secondary and the loop, to obtain an output monitoring signal. The third, or middle conductor is incorporated in a magnetic circuit to obtain the monitoring signal. This forms a symmetrical circuit which can be affected by mechanical or electrical factors along the line to give an interference signal. The cable is positioned in the air gap between the poles of a magnet (1), with a second magnetic circuit (5) for each monitoring point. The tapping point on the secondary coil at the remote station is selected to give the required balanced condition of the symmetrical circuit.

Title: Terminal connecting coaxial cable to printed circuit card - holds inner conductor between tongue and terminal bore by screw
Inventor: BAACKMANN DIRK ING GRAD
IPC: H01R13/646
Filed: 1979-10-10
Abstract: The proposed connector comprises a clamp shell (18) with a clamping screw (20) in a tapped hole at right angles to the shell bore. The shell is attached to a conductor strip (21) which also forms a tongue (25) projecting through the bore of the clamp. The inner conductor (14) of the coaxial cable enters the clamp between tongue and bore. The screw (20) is then tightened onto the tongue to trap the conductor. The screw thus causes no cutting action on the conductor (14) which could ultimately lead to a failure of the latter in service. The conductor strip (21) is mechanically attached to the circuit card (15), for example by a rivet (23). An extension of the strip can pass through a hole in the card for connection to the appropriate printed conductor.

Title: Pressure control for vacuum servo pump - has pressure limiter on suction line to allow pump to idle when servo not used
Inventor: RUF MAX
IPC: F04B49/02
Filed: 1979-11-16
Abstract: The vacuum servo line pressure control has a valve (9) which vents the line above a set vacuum level to allow the vacuum pump to idle. This relieves the pump (1) of drag and wear and provides a consistent servo level. The vacuum servo drives ancillary gear while the control valve has a single membrane (10) which lifts the venting valve element (18) against a return soring (19). One side of the membrane is subjected to the vacuum-level in the ancillary line (4) and when this reaches a set value the pump is vented.
