Title: Instant supply circuit for TV receiver - has voltage divider reducing supply to non:operating level but adequate to preheat tube
Inventor: OHE WILFRIED VON DER
IPC: H02M3/338
Filed: 1976-06-03
Abstract: The instant-ON supply circuit, for a television receiver, does not require the viewer to switch off the normal power supply. An isolation transformer has its primary supplied with current pulses from a switch and its secondary coupled via a rectifier to the receiver circuitry. For instant switch-on, two low-ohmic resistors (17, 18) are connected to the secondary so that the working voltage (160, 19, 12V) are reduced to levels that are no longer adequate for the receiver to function. The resistors are used to obtain voltages sufficient for the functioning of the remote control and for preheating the tube.

Title: Multilayer ceramic capacitors - having metal layer on each foil with dielectric border so stacks are flat after sintering
Inventor: HOEFFGEN DIETRICH DR RER NAT
IPC: H01G4/30
Filed: 1976-12-21
Abstract: A multilayer ceramic capacitor is made using a stack of thin, self-supporting, unbaked ceramic foils. Each foil is coated, at least on one side, with a layer of metal which only reaches one edge of the foil, leaving a border along the other edges. The foils are stacked so the metal on the edges of alternate foils reaches one of two opposite sides of the stack, which is then sintered; and the adjacent metal layers on each of the two sides are connected together by a solderable metal. The bare borders of each foil are pref. coated with a dielectric layer of the same thickness as the metal layer. The dielectric layer pref. uses a material (a) with the same dielectric constant and the same temp. coefft. as the ceramic foil, the dielectric layer being applied by screen printing, esp. using a material (a) with a slightly lower sintering temp. than the ceramic foil. The dielectric layer has the same thickness as the metal layer on each foil, so there is no air gap or cavities between the edges of the foils and a densely sintered, flat stack can be obtd.

Title: Moulding curved plastics printing plates - between cooperating moulds adapted to release the plates first at their edges then at their centres
Inventor: DARNALL JUN JOHN CORREN
IPC: B41D3/04
Filed: 1977-04-18
Abstract: Apparatus for moulding curved plastics printing plates comprises an outer female mould half and an inner male mould half comprising a centre section having diverging lateral surfaces and a pair of side sections which cooperate with the lateral surfaces of the centre section. Each side section is provided at its edge with a bar defining a hooked end of the plate. Means are provided to first withdraw the centre section of the male mould relative to its side sections to cause the side sections to move inwardly and pull the edges of the plate inwardly away from the female mould and then to withdraw all sections as a unit to pull the central section of the plate away from the female mould. Continued movement of the centre section causes the bars to release the hooked ends and finally the hooked ends to be pushed from the side sections to completely release the plate. The partial release followed by full release avoids subjecting the surfaces of shear forces and thus the surfaces remain undistorted.
Patent DE-2717583-A1 (DE)
Title: Rotary dryer for solids - with rate of bed transport easily modified, independent of slope, cylinder speed and air-speed
Inventor: SAEMAN WALTER CARL
IPC: F26B11/04
Filed: 1977-04-20
Abstract: Rotary dryer incorporates a cylindrical shell with feed at one end and discharge at the other. Inside the shell there are sets of flights, each set being associated with a dam ring. The flights are spaced peripherally. The ring is spaced downstream of the flights, giving a zone free from flights. Adjustable scoops carry the material from this zone over the ring to the down-stream side, permitting variation in the amt. of material held upstream of the ring. In addn. there is a spiral conveyor carrying the material from the flight-free zone to a point near the upstream end of the flights. The shell has a cooling section with flights. There is an inlet for co-current flow of drying air at the feed end and an inlet for countercurrent flow of cooling air at the discharge end. The rate of transport of the bed is independent of the rate of air flow, the rate of rotation of the drier and its slope, and can be readily changed; the distribution of the bed upstream of the ring is equalised, equalising the coefficient of heat transfer.

Title: Fluid flow velocity meter using thermal injection - has heating coil for heat pulses and thermoelectric sensor with digital timer
Inventor: JUFFA RICHARD
IPC: G01F1/704
Filed: 1977-05-26
Abstract: The fluid flow velocity meter consists of an insulated pipe in which is fixed a platinum heating coil energised by capacitive discharge, to provide a pulse of heat for the medium flowing in the tube. Some distance along the pipe is located a thermoelectric sensor in the form of a highly-sensitive differential detector. The output is connected to an amplifier which responds to the leading edge of the incoming pulse. A multivibrator is triggered by the heating pulse to the coil and reset by reception of the delayed pulse at the detector. The transit time of the thermal pulse along the pipe is inversely proportional to the flow velocity. This is determined digitally by measurement of the reset time of the multivibrator.
