Title: Fuel injector for IC engine - has plate type closing spring to reduce weight of moving parts
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/08
Filed: 1979-06-29
Abstract: The injector has a body (1) with a fuel passage (13) through it. It is closed by an end plate (2) with an outlet orifice (3) in it. A needle (8) with a cone (10) on its end acts as a valve in the orifice. The inner end of the needle has a mushroom head (9) which holds it to a plate spring (4). The spring is a rectangular strip bent into a bracket with its ends supported on the inside of the end plate. Fuel pressure on the underside of the spring opens the valve. The absence of a spring collet reduces the moving weight and increases the natural frequency.

Title: Additional anode grid gas discharge display - has sequentially activated cathode strips running parallel to line conductors
Inventor: GEFFCKEN WALTER DIPL ING
IPC: H01J17/49
Filed: 1979-06-29
Abstract: Reduced interference between the line and column conductors of the gas discharge display is ensured by an additional anode grid located in the discharge space before the control plate. The spacing of the anode grid from the conductors is 0.5-10 mm while the width of cathode strips is 20-50 mm. The anode grid is made either from wires or by etching a metal sheet. To prevent a gas discharge in the whole space the cathode strips are sequentially activated while the line conductors of the control plate carry out only the function of electron line control. The cathode strips (1) run parallel to the line matrix line conductors (4) of the control plate (2).

Patent DE-2931123-A1 (DE)
Title: Parity check for data transmission - accepts data without parity bit if authorised and inserts locally generated parity bit
Inventor: RICHTER OTTO DIPL ING
IPC: G06F11/10
Filed: 1979-07-31
Abstract: Data transmission over a busbar, with one line for a parity bit, is checked at an interface by regenerating the parity bit and comparing it with the received bit in an Exclusive-OR gate. Disagreement produces an error alarm output. This system is modified to accept data without parity bits, provided each word is accompanied by an authorising bit (A) on another line. Either the received parity bit (P) or the locally generated bit (G) is passed on (X) by two AND-gates (U1,U2), controlled by the authorisation bit (A), and feeding an OR-gate (O). The error alarm is suppressed by feeding the authorisation bit to two OR-gates, one in each input to the Exclusive-OR gate.

Title: Polyether poly:amine(s) useful as dispersants and in oil-fields - as demulsifiers, corrosion inhibitors and acid retarding agents
Inventor: DIERY HELMUT DIPL CHEM DR
IPC: C09K23/42
Filed: 1979-09-25
Abstract: Polyether polyamines of formula (I) are new: (where R1 and R2 are the same or different, and are C8-C30-alkyl, -2hydroxyalkyl, or-alkenyl, or C8-C24 alkoxypropyl; m and n are 2 or 3; R3 is CH3 or H; and (o+p+q+r) is 4-600). Also claimed are their prepn. by the reaction of R1-NH-(CH2)m-NH-(CH2)2-NH-(CH2)n-R2 (II) with ethylene oxide or propylene oxide, and their uses as dispersing agents and in gas- and oilfield applications.. Where (o+p+q+r) is 60-450, the cpds. are useful in low concns. as dispersing agents for organic and inorganic pigments, dyestuffs, and colour brighteners. The dispersions can be used in dyeing with dispersion colours, pigment printing of textiles, and in flexo- or gravure printing. When (o+p+q+r) is 4-150, the cpds. and their salts are useful in oilfields as corrosion inhibitors, demulsifiers, and acid retarding agents (these moderating the attack of e.g. limestone by pumped-in acids).
Patent DE-2943685-A1 (DE)
Title: Centrifugal coupling suitable for electric motor brake - has tapered or barrel shaped weights or balls locking between braking members
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: B60K17/02
Filed: 1979-10-30
Abstract: The centrifugal coupling which can be used for an inertial braking system, and which can be directly mounted on the drive shaft of an electric motor, has sets of weights carried by a plate attached to the drive shaft as in the main patent. The sides of the set of weights can slope so that they act as wedges against the sides of two plates mounted on the shaft. These weights protrude through openings in the plate, and can slide along a spindle inside each opening. Another design uses one weight with a convex surface, instead of a set of disc shaped weights. Another design uses balls which lock between sloping surfaces.
Patent DE-2943999-A1 (DE)
Title: Concrete formwork panel with facing sheet - has reinforcing inlay of textile or glass fibres for bending strength
Inventor: ESPE ROLF
IPC: B32B21/08
Filed: 1979-10-31
Abstract: A concrete formwork panel coated on one face at least with a facing sheet contg. hardened synthetic resin possesses, on one or both faces, a layer of textile fibres or glass fibres spaced at 0.5-4 filaments per cm in both warp and weft directions; these layers are adjacent to the surface of the panel cross-section more, specifically at the surface or at up to 2.5mm beneath it. Pref. filaments are of polyester, polyamide or viscose fibres. Used esp. for concrete formwork panels in which the surface coating has been applied to produce a good finish to the concrete and permit easy stripping of the formwork. Moisture penetrates easily into the panel and, esp. after repeated use e.g. in precasting works, the panel can become highly satd. Sunshine can also cause drying out. These properties cause deterioration in the bending strength of the panel. Incorporation of reinforcing layers as described on one or both faces, improves the bending strength of the panel considerably.
Patent DE-2952387-A1 (DE)
Title: Transfer marking film - comprising light sensitive cpd., reflective pigment and thermoplastic polymer, useful esp. as universal product code labels
Inventor: DESSAUER ROLF
IPC: G03C5/56
Filed: 1979-12-24
Abstract: Transfer marking film comprises a support with a marking layer comprising (a) a radiation-sensitive compsn. (I) which when exposed to radiation forms a coloured substance capable of absorbing light in the visible spectrum so as to cause a detectable difference in diffused reflection density between the exposed and unexposed areas; (b) a pigment capable of reflecting in diffuse fashion light of the wave length absorbed by the coloured substance, and present in an amt. of nearly equals 0.54-3.66 g/m2; and (c) a colourless film-forming thermoplastic binder which allows radiation to pass through. The transfer sheets are esp. useful for applying 'Universal Product Code' (UPC) markings to packaged prods. for supermarket stock control purposes. These markings are a series of bars and spaces which are read by diffused reflection. The transfer sheets gives the required contrast and accuracy to the markings and can be applied to a wide range of substrates.

Title: X=ray film cassette unloader and reloader - has four stage sliding transport and unload to processor plug size format gauging, etc.
Inventor: AZZARONI CESARE
IPC: G03B42/04
Filed: 1980-01-10
Abstract: The machine comprises a series of chambers through which the cassette is moved so that exposed film can be unloaded, and transported to the processor, and the cassette can be refilled with the correct size film. A slide mode of transport is used for cassette and for the film charges taken from and reloaded. When not in use the machine is totally closed and light tight. The machine has a first entry section to accept the cassette and move it into the second section where its size and format is determined and where a transport mechanism opens the cassette, takes out the film and transports it to the processor. A third section is the transport stage to the fourth reload section. The second, third and fourth stages are light-tight. The second and fourth sections are side by side alongside the transport and cassette opening appts. All cassette and film movement is by using slides and by sensing movement or travel distance using microswitches.

Filed: 1980-02-28
Abstract: The adjusting mechanism for a pair of dividers or compasses, includes a central adjusting wheel with its rim rotated inside a slot in a forked yoke between the tops of the two legs. Right hand and left hand screws (10) project respectively from each side of the wheel, to pass through internally threaded members (16) mounted on each leg. For fast adjustment, the threaded members are disconnected from the screws so that the legs can be swung inwards or outwards. Each threaded member consists of two halves (14,15) each with a half round stem projecting from a head, inserted through a hole through a leg, from opposite sides. Each stem has an elongated hole (18) for the screw, with half threads (20) at one end. When the two members are pushed inwards (23) against the force of a spring (21) the elongated holes enable both half threaded zones to be released from the threads of the screw.
