Title: Cross country ski binding converter - contains pivoted adjusting bracket with three positions for descent, ascent and cross country travel
Inventor: WILLBERG HANS-WOLFRAM
IPC: A63C9/00
Filed: 1976-05-13
Abstract: The converter makes it possible for a cross country ski binding to be used also for down hill or climbing. A vertically pivoted adjusting bracket (2) may be locked in three positions in the rear binding area. One position (A) fixes the binding (1) on the ski for downhill skiing while the cross-country position (8) frees the binding for the complete pivot range. In the climbing position (C) the bracket serves as a contact for the rear binding end at an angle of about 15 deg. above the ski, to avoid non-essential upward movement. The remaining pivot area is kept for the climbing movement of the foot.

Title: Microsoldering of hybrid thin film circuits - using stream of hot nitrogen as the heat source
Inventor: BRILL KLAUS DR
IPC: B23K1/012
Filed: 1976-05-18
Abstract: A wire is soldered onto a small assembly, esp. onto a hybrid thin film circuit. A pre-tinned solder point is heated by a stream of hot gas, and a cold solder wire is fed from a spool through a guide tube onto the solder point; after cooling of the soldered joint, the same guide tube is employed to break off the wire. The hot gas is pref. N2; and a cold stream of N2 is pref. used to cool the soldered joint. In the pref. appts, friction is used in the guide tube to convey the solder wire to the joint, after making the joint, a retractable mandrel is used to bend the wire downwards while the substrate is moved so the wire can then be soldered to a second pre-tinned joint. The guide tube is then raised and transversely oscillated to imposed bending stresses which fracture the wire above the second joint. Simple and reliable soldering involving the min. number of operations so the process only requires the min. amt. of time.

Title: Radioactivity monitor - with integration of semiconductor detector signals of different spectral sensitivity operating threshold trigger
Inventor: LECUYER PIERRE LEON DENIS
IPC: G01T1/24
Filed: 1976-11-26
Abstract: A radioactive radiation monitor consists of several solid state detectors which are simultaneously exposed to the radiation and are so interconnected that their individual spectral sensitivities are compensated. The resulting response signal is thus independent of the spectrum of the incident radiation. After integration in a charge pre-amplifier the resulting signal is used to act directly on the threshold trigger circuit. This monitor combines a uniform accuracy and constant sensitivity with an extremely small volume.

Title: Compression ignition engine with controlled compression - in which only part of air is compressed to achieve combustion temp.
Inventor: GROW HARLOW BOVIER
IPC: F02M59/36
Filed: 1977-05-05
Abstract: The compression ignition engine (10) has a piston (14) operating in a cylinder (12) which communicates with an air storage chamber (X) through ports (16). When the piston (14) passes the ports (16) only the air trapped in the combustion chamber (Y) is compressed to the pressure necessary to ignite the fuel supplied from the fuel injection system (Z). With this type of compression-ignition engine only about 10% of the charge air is compressed to the maximum pressure. This reduces the forces in the engine structure and enables it to be made lighter. It also allows the engine to work more closely to the constant pressure cycle than is the case with a Diesel engine.

Title: Pressure controller for encapsulated gas insulated HV ducting - is used for equalising pressure between duct sections and provides alarm facilities
Inventor: PERST GERHARD ING GRAD
IPC: H02G15/28
Filed: 1977-05-12
Abstract: The application is to metal encapsulated gas insulated HV ducts in which the kduct sections are subdivided by hermetically sealed bulkheads. A pressure monitor is provided for each section which passes a signal to a controller. Each section is connected by a valve to an equalising duct the valve position being regulated by the controller. Should a pressure difference arise the controller opens all the valves to restore pressure equilibrium. The valves close again at equal section pressure. The valves also remain closed if the differential pressure exceeds a preset value. The controller can be connected with an alarm system to give warning of valve operation, number of operations, and excessive pressure difference.

Title: Fully reclining chair with easy adjustment - uses weight displacement of occupant to adjust support members and arms
Inventor: FUSS RAINER
IPC: A47C1/035
Filed: 1977-05-26
Abstract: The seat (27) and backrest (35) of the chair are held supported on two transverse displacement supports (25, 26). These are connected together by longitudinally aligned positioning runners (24) which in turn rest on two transverse frame supports (22, 23) so that they can be displaced as required. The footrest (16) of the chair is connected to the framework (10) by two positioning arms (15) hinged to the slide runners (24) by a positioning lever (20). The chair can be adjusted solely by shifting the weight of the occupant causing the runners to move easily in guides in the frame. The point of rotation of these runners lies roughly in the centre of gravity of the person resting on the seat and backrest. The footrest moves rapidly in association with the other movements.
