Title: Fail-safe ignition key lock - with cam controlled ring to hold ignition on until key fully withdrawn
Inventor: SCHWAB DITTMAR
IPC: B60R25/021
Filed: 1974-03-07
Abstract: The keyhole is fitted with a control ring which rotates relative to the lock cylinder and which has to be rotated by the key to line up its slot with that of the cylinder before the key can be inserted. The ring acts in conjunction with a fixed cam so that when the key is turned the interaction of the ring and cam move the ring and cylinder axially before the key is fully inserted. This acts as a fail-safe mechanism in that the key has to be fully withdrawn before the ring can return to its axial setting and before the steering wheel lock can function. The system is simple and fool-proof, and requires only the ring and cam parts.

Title: Knitting loop pile fabric on circular knitting machine - having hook needles which are used to form a pile yarn into loops
Inventor: SCHMIDT WALTER RICHARD
IPC: D04B9/12
Filed: 1974-03-25
Abstract: A circular knitting machine includes an upper needle bed supporting radially extending pref. latch needles to effect a base knit from a base yarn and a number of hook needles arranged in a cylindrical needle bed and used for forming a pile yarn (introduced into the base knir) into loops to form a loop pile. During knitting the hook needles are raised to the position in which they can gather the pile yarn as the latch needles are retracted after knitting a stitch and then raised to the knitting position before the latch needles are extended to the knitting position to prevent the base knit from moving with and being distorted by the latch needles. Unselected hook needles are lowered to an inactive position before the pile yarn is fed to the hook needles. The base knit is prevented from being distorted by the latch needles. A stitch of the base knit and a loop are formed simultaneously allowing a long, uniform loop to be produced.

Title: Store with optically read ferromagnetic elements - uses a polarized light wave reader and possible use of filters
Inventor: II LAWRENCE BURTON
IPC: G11C11/56
Filed: 1974-05-02
Abstract: A storage element is formed using ferromagnetic components, which are read by light waves acting on photo-electric sensors. The light waves are arranged to travel through polarisers before they impinge on the sensors, and consequently addressing takes place, since the route taken by the light waves is dependent on the configuration of the polarisers at the time. Filters may be interposed in the light path to increase the selection range of the addressing. The arrangement is extremely small compared to conventional systems.

Title: Accelerating composting of waste prods. - by adding aerobically thermophilically treated sewage
Inventor: LOLL ULRICH DR ING
IPC: C05F17/00
Filed: 1974-10-09
Abstract: The composting of solid waste prods. is initiated and accelerated and odour is prevented by the admixt. of aerobically-thermophilically pretreated waste-water or sewage slugde. Aerobically-thermophilically treated highly conc. waste water or sewage sludge is very rich in active rotting organisms suitable for the odourless composting of solid waste prods., and can be stored for long peridos without loss of quality. Composting times can be shortened by days or even weeks, on account of the ease with which the inoculum can be intimately mixed with the solid waste prods. The odourless nature of the composting process leads to a redn. in costs because of the reduced need for special odour-reduction measures. The process offers a means of using up highly conc. waste waters or sewage sludge while at the same time speeding up the composting of solid waste.

Title: Handshaking addressing over bus lines in data processors - removes errors caused by addressing failures preliminary transmission of call:up and answer addresses
Inventor: BIZER WERNER DIPL ING
IPC: G06F11/16
Filed: 1975-10-22
Abstract: The method of address handshaking is protected from errors caused by addressing failures. Typically, a highway, or bus line (1) in a central processor is connected to a store (3), processor (2), and other such networks (3,4). In this method before a unit transfers data to another unit, it first generates a call up address on the bus lines, and this is decoded and accepted by the receiving unit. This then generates an answer address on the lines, which may or may not be the same as the call up address and this is recognized by the sending unit. Only then is the data transmitted. The data itself may also, in certain cases, be retransmitted from the receiving unit to the sending unit, where it can be checked against the original data.
