Title: Engine speed governor for fuel injector pumps - has additional leaf spring to give fuel overload for start purposes
Inventor: EHEIM FRANZ
IPC: F02M41/12
Filed: 1974-01-23
Abstract: Engine speed governor in which revolving centrifugal weights allw an over load fuel regulator annular slide position for start purposes, and then regulate the slides position via a sleeve moved axially by the governor weights outwards motion. Patent 449859 is further improved by providing a connecting lever which pivots on a fixed axis in the pump housing, one free end having a head to fit inside a recess in the fuel regulator collar whilst the other end meshes with the centrifugal weight sleeve. A drag link is independently pivoted to the same axis as the connecting lever and runs parallel to the connecting lever to its anchor point with the main regulator spring. A leaf spring is rivetted to the drag link near the main spring, lays between the two levers, and is so formed that a force is exerted between the two levers to keep them apart. The leaf spring is preferably of bi metal to give a stronger tension under cold conditions.

Title: Hot tops of metallurgical casting moulds - from granular and fibrous materials with binder contg. resin, starch and alum
Inventor: HEIMBACH KARL-FRIEDRICH DIPL C
IPC: B22D7/10
Filed: 1974-07-22
Abstract: Fireproof heat-insulating compsns. for hot tops of metallurgical castings moulds prepd. from pulverulent or granular inorganic materials, and inorganic or organic fibres, with addition of about 10% of a binder, are improved in that the binder consists of a mixt. of 20-90% of a thermosetting synthetic resin based on a phenol- and urea-formaldehyde condensate(s), 60-9% of a starch product and 20-1% of an alum having the formula Me1. Al(SO4)2. 12H2O (in which Me1 is a monovalent cation such as K+ (pref.), Na+ or NH4+). The addition of an alum stabilises the compsn. so that it can be stored for a prolonged period of time without losing its mechanical strength when used as a hot-top. The hot-top shell can be easily detached from the ingot. The binder is much cheaper than the conventional all-resin binders, and yet the mechanical strength of the product is improved. The moisture absorption during the storage is low.

Title: Door with frame and covering panels - is stabilised by foam plastics filling and internal support strips
Inventor: BAUER JOSEF DR
IPC: E06B5/20
Filed: 1974-10-01

Title: Matrix addressing system for fluidic-crystal display panel - has perpendicular coordinate conductors dividing panel into discrete segmental areas
Inventor: SHERR SOLOMON
IPC: G09G3/36
Filed: 1974-10-10
Abstract: The two sets of conductors are perpendicular, so as to define X and Y co-ordinates, with the panel surface divided into segmental areas by the conductors. The latter are connected to a control circuit for applying a potential to selected conductors of each set, with the state of the fluidic crystal material in each segmental area dependent on the voltage between conductors defining the area. The conductors may alternatively be arranged along radial and angular co-ordinates of a circular display panel, e.g. used to provide an analogue time display, with the control circuit supplied via a counter circuit.

Title: Flash-lamp for photography - has capacitor charged and discharged through light emitting gas discharge lamp
Inventor: SAUER ARMIN
IPC: H05B41/32
Filed: 1974-11-02
Abstract: The lamp is ignited by an ignition pulse released by the flash-lamp contact. An integrator is supplied by a photoreceiver and, after a presettable quantity of light is received, delivers a control pulse to a switch which breaks the flash-lamp circuit. The camera flash-lamp contact controls a switching device which prepares the photoreceiver and/or the integrator and trips the lamp ignition. A delay circuit is inserted between the switch and ignition circuit. An exact exposure is achieved since shutter inertia effects do not arise, the opening of the shutter lasting longer than the flash light timing.

Title: Laminating sheets esp fabric, with several coatings - which are applied wet using temporary transfer strip and then all dried
Inventor: WEBER KARL-ARNOLD DR
IPC: D06N3/14
Filed: 1974-11-22
Abstract: Two or mroe coatings are applied to a sheet, e.g., of textile (woven, knitted, non-woven) leather, rubber, foam, and contacting the coatings before drying. The still wet coatings are joined together without shear forces occurring between them. A (final) coating is pref. applied to a temporary support, while a bonding (under) coating is applied, simultaneously but separately, to the permanent substrate; the two sheets are then brought together, before their coatings dry, by converging, at an almost tangential approach angle, to produce a laminated structure; this laminate is dried, then the temporary support is tripped off.

Title: Embossing process for credit cards using heated tools - to heat thermoplastic card to viscoelastic region enabling old data to be erased
Inventor: ROESER WILHELM DIPL ING
IPC: G06K1/12
Filed: 1975-03-05
Abstract: A thermoplastic credit card with embossed characters is produced in such a way that information may be erased at the same time that new information is substituted. The single layer thermoplastic card (1) is fed between embossing rollers, one containing male versions of the symbols to be produced (5) and the other the female counterparts (6). The two rollers are geared together to ensure synchronous motion. A UHF generator coupled to the rollers raises the temperature of the card and the process occurs in the viscoelastic region. In this way previous data is eliminated and new data entered. An alternative version uses a linear motion embossing tool.

Title: Remote volume control for radio receivers - brackets important broadcasts by frequency modulation of basic tone in order to give high volume
Inventor: THEVENIN CLAUDE GABRIEL JEAN
IPC: H04H1/00
Filed: 1975-04-23
Abstract: The remote volume control, for radio receivers, allows certain transmissions (e.g. traffic information warnings etc.,) to be broadcast in such a way that they are reproduced at the receiver with a volume greater than normal -- thereby attracting the attention of the listener (and also receiving hind of the tiresome effort of listening to programmers for which he has no interest just to hear e.g. traffic information). The traffic broadcast is bracketed between two signals represented by alternate jumps in the frequency of a basic tone and at a rate less than the basic tone frequency. The start and stop bracket signals differ in frequency sweepby double demodulation. The last demodulator causes changes in the receiver volume.

Title: Electric machine winding head taping and forming method - uses slidable tape to be wound around winding head
Inventor: RIST OTTO
IPC: H02K15/00
Filed: 1975-05-23
Abstract: To secure the windings on the coil of a dynamo-electric machine, a two-pronged fork (12) is passed over the adjacent, projecting outward loop ends and then rotated about its axis. The double tape forms then a roll, so that the loop tightens over the winding head and pulls it to the required size. The roll is subsequently secured against unwinding by an adhesive strip across the ends of the binding tape. Two U-shaped spring members may also be used as spaces with the flattened base of the U in contact with the inner face of the former.
