Title: Timing valve for IC warm up control - has electronic control unit providing variable length pulses dependent on engine measurement data
Inventor: ABTHOFF JOERG DR ING
IPC: F02D41/06
Filed: 1977-10-15
Abstract: Warm control for i/c engines, partic. for oxygen sensor governed engines, involves a feed unit for input of the correct fuel amount in relation to the combustion air, a fuel feed pump, and a control throttle. The latter automatically sets a constant feed pressure for input fuel. Parallel to the control throttle (4) is at least one timing valve (3) which is closed in the rest position, and which, during the warm up phase of the engine, opens on a time basis. An electronic control unit, activated by engine measurement data, is provided to produce time impulses of variable length. The time valve (3) cycle is such that it is switched on for longer periods at the commencement of the warm up phase than at the end.

Title: Electrical vehicle traction system - has motor which is regulated by flywheel generator which stores energy
Inventor: SUGIYAMA SHUICHI DIPL ING
IPC: B60L50/30
Filed: 1977-11-16
Abstract: The main traction motor (1) is wired in series with a fly wheel generator (3) a control switch (4) and the current collector (6), to a positive poled direct current source. The traction motor feed is varied from nil to maximum by altering the flywheel generator voltage. At low speed, the flywheel generator works as a motor to store energy. The stored energy is returned to the traction effort in the higher speed ranges. It is possible to store energy in the flywheel before the vehicle is started to improve the acceleration rate. A block diode (5) is parallel with the generator and traction motor enables the traction motor to be fed from the generator when the switch (4) is open. For braking purposes the main feed is switched off and the two traction motors are connected parallel to the generator.

Patent DE-2905796-A1 (DE)
Inventor: NOACK FRITZ DIPL ING
IPC: E01C5/00
Filed: 1979-02-15
Abstract: A ground covering element adapted for positioning adjacent another ground covering element. The outer contour of the ground covering element forms projections and recesses about its entire periphery, has corner projections which form the vertices of a rectangle and line portions all of which are oblique to the sides of the rectangle connecting the corner projections. At least two of the line portions connecting each of the vertices are of equal length and the remaining line portions have lengths which are integer multiples of the lengths of the at least two line portions of equal length. A plurality of irregular spaced polygons project from the top surface to form raised portions, the majority of the polygons differing in shape from each other. The edges of the raised portions are straight and separated from each other by dummy gaps having widths which vary linearly along the entire length thereof and from the periphery of the ground covering element by marginal dummy gaps. The edge of each raised portion adjacent the periphery of the element substantially follows the contour thereof and has a distance therefrom such that the average distance between the edge of the raised portion adjacent the periphery and the contour is approximately equal to the average width of the dummy gaps between the raised portions. Sand is used to fill the space between the adjacent ground covering elements thereby effectively concealing this space from view.

Title: Lead accumulator electrode sheath - is bag of very finely woven filaments e.g. of polyethylene, polyester and opt. glass to increase stability
Inventor: METZLER OTTO
IPC: H01M50/414
Filed: 1979-03-15
Abstract: Accumulator electrode consists of lead with a bag-shaped sheath of very finely woven filaments of O2- and acid-resistant plastics, e.g. polyethylene and/or polyester and opt. glass fibres, having a porosity of over 65 (70-75)% at a pore size of max. 01 mm. Fabric is woven in one or more plies and is coated with colloidal graphite (to increase the capacity yield). These bags give very long stable periods with positive and negative plates, the capacity and stability increasing with the porosity and fineness of the pores. They reduce the sludge from positive plates and hence the danger of short circuits and increase the lifetime of negative plates considerably.

Title: Sun lounger with wind and radiation protection - comprises cloth-covered U-form frames with bracing longerons secured at pivot points
Inventor: SCHUPPERT HEINZ
IPC: A47C17/72
Filed: 1979-07-05
Abstract: The sun lounger (10) includes two frame shaped members (11.1, 11.2) comprising the lower crosspiece (11.3) and the two side members which extend to the pivot axis (12). These side members (11.4, 11.5) extend also past the pivot (12) and are kinked to improve the folding capability, ending at a longeron (11.8). At the seating level, longerons (13.1) and (13.2) are firmly fixed to the side members. Between this, the supporting cloth (14) is stretched, which hangs loosely when the framework is in the folded position. As the axis (12) lies considerably higher than the support cloth (14), a stable frame results.
Patent DE-2932011-A1 (DE)
Title: Plastic brush base - with hard core for bristle tufts fixing and elastic polyurethane shell
IPC: A46B5/00
Filed: 1979-08-07
Abstract: The Parent Patent No. 2917878 described a brush with tufts of bristles, fitted into a base of varying specific density in different cross-sections. It is now suggested to use an inner hard core to enclose the roots of the bristle tufts and to surround it by a soft polyurethane shell, pref. with a skin of higher density. The core can consist of rigid polyurethane foam, a thermoplastic foam with a hardness and density pref. rising towards the surface, or of wood. A barrier coating can be applied to the outside. The result is a better chemical resistance. When used in the fish or meat trade, decomposable substances cannot penetrate into the base.

Title: Sliding front seat mounting for rear seat access - has pivoted support rectangle to swing seat forwards on backrest tilting
Inventor: STOLPER RICHARD
IPC: B60N2/12
Filed: 1979-11-28
Abstract: The sliding front seat mounting for a car has the seat back linked to the mounting by a parallelogram formed by a front pivot lever (16) and a rear pivot (28,29) as well as the seat base and the squab. As the seat back is pivoted forward, the seat swings forward on the levers to improve access to the rear seats. The seat back pivot (13) is on an extension arm (27) to one side of the parallelogram so that an enhanced forward swing is obtained. When the seat back is lifted again the seat assumes its original setting, with a security lock to hold it.
