Title: Alarm system with programme facility - has sensor inputs coupled to comparison stages operating over programme controlled relays
Inventor: BEIGEL HELMUT
IPC: G08B29/08
Filed: 1978-10-07
Abstract: An alarm system provides for multichannel monitoring of a range of sensors. The sensors are used for fire smoke or intruder detection. The system allows for cycle variations to be programmed. Each of the channels (51, 52) are optically isolated from each other and have alarm and sabotage output lines (70, 71). Input lines (57, 58) are coupled to a frequency divider (59) connected to voltage comparators (60, 61). Coupled logic stages (75, 76, 67, 64, 66, 65, 69) process the generated outputs over relays that are programme controlled.

Title: Test card selection and checking system - uses slot along edge of card container, permitting insertion of checking member
Inventor: WENDT RUEDIGER
IPC: G09B3/08
Filed: 1978-11-18
Abstract: The correcting or checking device for test cards is used for the multiple choice question and answer system. It has a test card support plate (1) which rests on top of a rectangular tray (2), leaving a gap (3) along one edge. One long side of the tray is open. The tops of the cards are thus visible through the gap before checking. After checking the cards can be removed through the open side. The selector clip consists of a flat strip with two side plates near one end, this latter end thus having a V-section. These two side plates are inserted through the gap to contact the cards below. There is an alternative design with a raised portion forming the gap for insertion of the selector.

Title: Express test for alpha-amylase - by gel diffusion in plates contg. amylopectin coupled with dye
Inventor: TAUSCHEL HORST
IPC: C12Q1/40
Filed: 1978-12-21
Abstract: A test for rapid determn. of alpha-amylase in liq. samples is claimed. The test is carried out using a diffusion plate in which the diffusion layer has one or more cutouts for applying the sample. The diffusion layer contains an alpha-amylase substrate comprising amylopectin coupled with a reactive dye. Also claimed is a process for preserving diffusion plates of the above type, in which the diffusion layer is covered with a water-permeable cellulose foil and the plate is dried. The test can be used for diagnosis of pancreatitis, renal insufficiency, biliary disorders, viral hepatitis, tumours, etc. The plates give a linear response over a wide range of alpha-amylase concns. (e.g. 0.001-1000 mu/ml.), even with short incubation times (e.g. 5 min.). Using the new process, the developed plates can be preserved without damage and without alteration of optical properties.

IPC: E04F11/18
Filed: 1978-04-22
Abstract: The handrail (8) which may be oval in section, is supported by vertical tubes (1) each with a fitting inside the top to form a joint. A cross strap (2) is welded inside the top of the tube. This has two holes (2c) through it for the two arms of a connecting rod (3) bent into a U shape, to pass through. The ends of these arms are screw threaded and are fitted with bulbous shaped dowels (5), each with a sleeve (6) around it, slotted at the outer end. These bulbous heads are fitted into corresponding holes through the handrail (8).

Title: DC load voltage stabilising circuit - has protective switch controlled by voltage of DC converter and positioned between switch-over contact and auxiliary rectifier
Inventor: FELDMAIR LEONHARD
IPC: H02J7/34
Filed: 1979-06-28
Abstract: The circuitry stabilises the load voltage in d.c. supply installations. Battery cells are automatically switched on if the mains fails so that it can serve as an emergency stand-by source. Main and auxiliary rectifiers are used for charging main and switching cells of a lead-acid battery in a buffer circuit. The auxiliary rectifier is in parallel to the switching cells. The main rectifier is directly parallel to the main cells. The latter can be connected to the load via the contacts of the switch-over arrangement. The input of a d.c. converter lies parallel to the main battery. One output terminal of the converter is connected to one pole of the main battery, while its other output terminal is coupled to the switch-over contact. Between the latter and a pole of the auxiliary rectifier lies the switching path of a simple protective switch controlled by the output voltage of the power converter.

Title: HV cable junction with insulation filled equipment - prevents egress of insulating material using shaped sleeve with annular wall clamped between two end plates
Inventor: GERAEDTS DIETER
IPC: H02G15/013
Filed: 1979-09-11
Abstract: The junction is for HV synthetic insulated cable entering some form of equipment such as junction box filled with an insulating material. The junction prevents egress of such material along the cable. The cable (1) enters the equipment (6) complete with its outer insulation which is stripped off a short way in to expose the outer conducting sheath (2) and then the inner insulation (3). Sealing is achieved by a sleeve (5) fitting over the outer conductor and inner insulation section and then increasing its diameter to cover the outer insulation. The sleeve then folds outward through 90 deg. to form an annular wall terminated in a thickening of the material. This is clamped between two end plates to provide the seal. Where a cable is required to enter the equipment more deeply inner and outer clamping rings secure the sleeve.

Title: Anti-fly device for wave-shed looms - creates outward air current through weaving elements preventing fly deposition
Inventor: LINKA ADOLF
IPC: D03D47/26
Filed: 1979-09-27
Abstract: Wave-shed loom has an air tube extending across the full width of the loom below the beat-up lamellae, with apertures from which issue multiple air-jets forming an air curtain in front of the weaving elements which prevents the ingress of dust and fly. The air tube is pref. divided into several sections, each being independently connected to a common compressed air supply, to maintain a uniform air curtain across the loom width. The device prevents the accumulation of foreign material, which could reduce the loom efficiency, on the poorly-accessible moving parts in the region of the fell.

Title: Spark plug electrode assembly - has long reach for high heat conductivity and heat dissipation of electrode
Inventor: LATSCH REINHARD DIPL ING DR
IPC: H01T13/20
Filed: 1980-03-08
Abstract: The spark plug has long reach electrodes to prevent them heating up to cause pre-ignition or 'running on'. The long reach extends into the centre of the combustion area and permits use with high engines of compression ratios. The centre electrode and the outer electrodes of both designs are made of corrosion resistant metal. A conventional long 'L' shaped outer electrode is used and in the second a ring of outers are used. The centre (29') and outer electrodes (33',39) extend by between 5 and 30 mm out of the coaxial type plug casing (11). The outer electrode (33') uses Natrium on its inside surface to aid heat dissipation. The outer electrode (33',39) may be a ring assembly around the centre (29') electrode. The plug casing (11) is a coaxial body sealed with insulating material which separates the centre and outer electrode connections.
