Patent DE-2749112-A1 (DE)
Title: Plastics toy mast prodn. method - by injection moulding over cross form leaving grid and groove for lamp and conductors
Inventor: ROETHER HELMUT
IPC: A63H33/04
Filed: 1977-11-03
Abstract: The toy mast is made by injection moulding. The mast cross section has cruciform arranged flash ribs which are removed for producing conductors carrying electricity to the incandescent bulbs at the mast top. The injection moulded component is relieved of moulding flash diametrically. Subsequently this mast is metal coated and finally its profile is moothed and flash is removed in two further operations. The flash ribs are removed on rounding the mast profile so that the metal deposits are separated from each other. Thus with four flashes four separated metallic coating areas are provided for conducting electricity to the lamp.

Title: Plastics cup stack advancing mechanism - has advancing members travelling above guides compressing stacks into closer formation
Inventor: LAUERMANN WALTER
IPC: B65B35/40
Filed: 1977-11-21
Abstract: The advancing mechanism at the discharge end of a moulding machine for plastics cups, is used with two side guides (2) each with a sloping portion which helps to guide a set of stacks (5) of cups so that they are moved closer together. For the earlier part of their travel, the stacks pass between parallel guides (4). These stacks are pushed forwards by cross members (7) which slide along side guide rods (6) and moved by actuator cylinders (18). Each cross member has a drive element (9), one for each stack. Each drive element is attached to an adjusting bar (13), and an adjusting spring (12) and screw (11) for each element is between the bar and the cross member.

Title: Clamping of foils between panes, esp. in double glazing - where foils have a coating reflecting infrared rays but transmitting light
Inventor: WEINLICH TILMAN LUDWIG DIPL IN
IPC: E06B3/677
Filed: 1977-11-29
Abstract: The foils are fixed to individual frames (a) each possessing a profile which clamps the foils when the frames (a) are pressed together. The outer surfaces (a1) of the frames (a) which will be in contact with glass panes in double glazing, are pref. bonded to the panes before the frames (a) are pressed together to clamp the foils. Several foils may be clamped between one pair of panes; and an adhesive may fix the foils in their final position. The frames may form a spacer between two glass panes, the result being a sealed internal cavity which may be filled with a gas improving thermal insulation; and/or a desiccant may be included in the frames. The foils pref. have a coating reflecting infrared but so thin that the colour of transmitted light is not changed; and the spacer may contain sound absorbing material. Used for the inexpensive mfr. of multipane insulation glazing or covers for absorber plates used in solar energy collectors.

Title: Oxygen sensor for industrial air-fuel control - incorporating a protected solid electrolyte disc in a simple ceramic tube mounting to give accurate and consistent results
Inventor: SHUM MING SHUNG
IPC: G01N27/407
Filed: 1978-04-20
Abstract: An oxygen sensor particularly adapted for use in industrial air/fuel control systems incorporates a disc of solid electrolyte sealed into a recess in one end of a ceramic tube. The tube is sealed and mounted inside a holder assembly which can be screwed into an opening in the wall of a stack so that one face of the disc is exposed to the stack gas while the other is exposed to the ambient air. The electrodes are formed by painting the surfaces of the disc with a platinum paste while stripes of the paste, one on the inside of the tube and the other in a groove on the outside connect the electrodes to separate terminals outside the stack. Ceramic fibre discs are bonded to the disc surfaces and chloroplatinic acid is deposited on the electrode surfaces through the fibre discs. The sensor is simple and uses very few parts and only a small amt. of platinum. Dissimilar material junctions have been eliminated and the sensor is accurate and reproducible. The sensor has a lower operating temp. than other industrial sensors.

Title: Alarm monitoring system using change in impedance for trigger signal - incorporates reference impedance in emitter circuit of transistorised circuitry
Inventor: HIRRLINGER KLAUS DIPL ING
IPC: G08B13/22
Filed: 1978-12-05
Abstract: In the monitoring circuit an actual impedance is compared with a reference impedance. This is a measure of the state of the alarm equipment. It will make it difficult to sabotage the alarm system as the voltage will be kept constant and any change in current will trigger the alarm. The reference impedance has only one possible effective value and any change will therefore trigger the alarm. This reference impedance is incorporated in the emitter circuit of two transistors, with the bases joined and collectors connected to the bases of two other transistors. Operational resistors of complementary transistors are chosen in accordance with the ratio of rated and reference impedances, that the collectors of the first transistor pair have identical voltages, while the collectors of the other pair transmit a digital signal, corresponding to the monitored impedance.
