Title: Motor vehicle sliding door with swivel links - uses four bar linkage actuator with cam for moving door
Inventor: HEGR KAREL
IPC: E05F15/646
Filed: 1977-11-18
Abstract: Sliding door has guide drive by means of which the door is supported on the vehicles. This mechanism is a four bar linkage with the door and the crank arm acts as support between the door and vehicle. The second crank enables the door to swivel relative to the support arm. This sliding door swings out of its initial position on opening as a normal swivelling door. Swivelling movement continues until the other door edge has moved out of the door frame. The effective crank length of the guide is swivelled during the initial swivelling movement of the support arm (3) at least on opening the door (1). It can be rotated by means of an actuating cam (20, 21) acting on the guide element when the door is swivelled. The actuating cam (32) is fitted between the swivelling and of the guide. The cam ensures that the guide is moved outwards across the line connecting the pivoting ends.
Patent DE-2802885-A1 (DE)
Title: Fixing solar reflectors - using bonded discs on rear and elastic pads joining support structure elements
Inventor: WILDENROTTER KARL DIPL ING
IPC: F24S23/70
Filed: 1978-01-24
Abstract: Reflectors for use in solar heat collector installations are joined to a mechanical support structure by several independent fastening element at their rear. These elements are so spaced that the deflection of the reflectors remains within acceptable limits. Each element consists of a disc which is bonded to the reflector rear and is separated by an elastic pad from a member of the support structure. The deformation of the reflector by wind load, its own weight, thermal stresses etc. is thus kept to a min. and the focussing quality of the reflectors is not detrimentally affected.

Title: Premix forming dental filler when amalgamated with mercury - where premix contains reinforcing bodies coated with silver to prevent corrosion during storage of premix
Inventor: EURICH KLAUS
IPC: A61K6/847
Filed: 1978-02-03
Abstract: DT 2658785 described a premix contg. filings and mixed with mercury to obtain a dental filler which hardens at the temp. of the human body. The premix also contained skeleton- or reinforcing bodies (2) made of an Ag-Sn-Cu alloy and coated with a layer (3) of copper formed by chemical- or electroplating. The novelty in the present invention is that the Cu coating (3) is covered by a protective layer (4) of metal, which pref. forms an amalgam and has superior oxidn.- and corrosion-resistance to Cu (3) when the premix is stored prior to use. Metal (4) is pref. a noble metal, esp. silver, which is also present in the premix, and layer (4) is pref. 1 mu thick so it allows the Cu to participate in reactions when Hg is added to make the dental filler. With the original invention, the Cu coating (3) on skeletons (2) oxidised and interfered with the desired amalgamation. The Ag (4) prevents oxidn. of the Cu (3).

Title: Inspection system for semiconductor chips - marks defective chips with fluorescent dye visible under ultraviolet light
Inventor: MARTIN JOHN ELMSLIE
IPC: B07C5/34
Filed: 1978-02-17
Abstract: Fluorescent dye is used to mark the defective chips. The defective chips can be readily distinguished with the naked eye when they are viewed under ultra-violet light. It is also possible to distinguish those chips which have been accidentally marked and which need not be rejected. The use of ultraviolet light with a fluorescent dye eliminates the need for a microscope and reduces inspection time.

Title: Signal propagation time reducing PCM TDM telephone exchanges - has delay line which reduces interval necessary for PCM word retransmission
Inventor: REITZ ERHARD DIPL ING
IPC: H04Q11/04
Filed: 1978-05-17
Abstract: Coders and decoders are allocated to individual speech channels or subscriber lines, which convert analogue speech signals into PCM words. They reconvert incoming PCM words into analogue speech signals. A transmitter clock signal (T1) cyclically appearing and determining the beginning of transmission of a PCM word is applied through a delay circuit (VZ) to a switch taking over the analogue form into a PCM word, so that only a signal propagation time reduced by the delay time replaces the interval between the taking over of the speech signal by the switch and following sending out of the corresponding PCM word.

Title: Digital stabiliser suitable for testing communication lines - converts into AC output voltage of constant amplitude and of same frequency using comparator
Inventor: PEUSER WOLFGANG DIPL PHYS DR I
IPC: H03G3/20
Filed: 1978-07-21
Abstract: The amplitude stabiliser has two or more m-stage counters receiving clock pulses from a clock generator. A comparator compares the contents of the counters with the contents of a third m-stage counter. The third counter counts pulses of 2n times the frequency. Each time the comparator's inputs are equal, a counter with n+1 stages moves on and has its output converted into analog form. The advantage lies in using purely digital means to stabilise an a.c. input.

Title: Building element and surface seal elastic connection - has non-bonding area round sealing substance to accommodate movement of adjacent surfaces
Inventor: HAAGE KARL DIPL ING
IPC: E02D31/02
Filed: 1978-08-03
Abstract: A permanently elastic sealing substance is used for joining a structural element to a surface sealing unit, in building. The connecting zones (10, 11) between the sealing mass (6) and surface sealing (1), and between sealing mass and structural element (2) are separated by a defined nonbinding area (9), for absorption of increased movements. The connecting zones may extend at least roughly in the direction (A) of movement to be absorbed. The mass may be connected to the surface sealing by profile bars (3) force-locked to the latter with a watertight effect. This combines highly effective sealing with facility for considerable movement between structural element and seal, without excessive stress on connections.

Title: Dialysis membrane comprising hollow cellulose fibre - with improved exchange surface, extruded from cuprammonium soln. of cellulose
Inventor: BANDEL WERNER DIPL CHEM DR
IPC: B01D69/02
Filed: 1978-10-02
Abstract: A dialysis membrane of cellulose regenerated from cuprammonium solns. is in the form of a hollow fibre with a continuous empty space and a closed lateral surface. In a cross-section perpendicular to the fibre axis the difference of the distances of the lateral surface and of the boundary of the aperture varies each time from the centre of the fibre, over the circumference of the lateral surface. The membrane is mfd. by extrusion of a cuprammonium soln. of cellulose into an aq. caustic soda soln. through the annular slit of a hollow fibre die immersed in the aq. caustic soda soln. A liq. which will shape the empty space is extruded through the inner passage of the die. The ratio of the speed of drawing of the hollow fibre over the first drawing roller to the speed of extrusion of the cuprammonium soln. of cellulose from the annular slit is 1-1.05. The direction the fibre follows from the die to the first drawing roller forms an acute angle, pref. 15-70 degrees, with the axis of the die apertures. Subsequent treatment of the fibre is conventional. The membrane is used partic. in hemodialysis. The efficiency of dialysis is increased owing to an improved exchange surface.

The appts. is used for to effect cooling or preheating of gases or liqs. and the moistening of a gas. It is partic. useful for concn. by evaporation and for distn. of materials sensitive to high temps. aliphatic acids, polyatomic alcohols, ethanolamines, oils, food and pharmaceutical products. The atomiser produces an intense degree of atonisation which renders more efficient the exchange process in the appts.
