Title: Accessory to prevent the crossing over of skis - has universal fixing base with variable clip-on top profile
Inventor: SCHWARZ GUENTER
IPC: A63C5/065
Filed: 1974-08-30
Abstract: The accessory is designed for fitting to all types and widths of ski. It consists of a standard base plate which is attached near the front of the ski. The base has upward projections which match clip-on recesses in the underside of a two part top profile. The upstanding sides of the profile are inclined towards one another and can be varied in width by selecting one of the several recesses for fitting to the base.

Title: Lift limiting aircraft wing - with spring loaded flaps through front part of wing to alleviate large thrusts
Inventor: BRDITSCHKA HEINRICH WENZEL
IPC: B64C3/48
Filed: 1975-07-25
Abstract: The front part of the aircraft wing is fitted with a number of parallel flaps which close off ducts through the wing from the underside, with the flaps closed by spring pressure. The springs are chosen so that they open the flaps when a set wing loading is exceeded. This reduces the lift of the wing and prevents wing damage. The system is especially applicable to gliders in which large wing loadings are experienced when the glider pulls out of a dive. The remaining wing area is still large enough for sufficient lift to support the aircraft. The design enables the wing weight to be reduced by up to 40%.

Title: Liquid crystal display with extra coatings on electrodes - preventing reaction with liquid crystal substance, for long term thermal stability
Inventor: KOBALE MANFRED DR PHIL
IPC: G02F1/1337

Title: Seive for vacuum sorting of rubbish - is formed by adjacent runs of belts of transverse and longitudinal wires
Inventor: FERRERO GIACOMO
IPC: B07B1/10
Filed: 1975-11-06
Abstract: The sieve comprises a set (A) of wires, each forming a closed loop (2) and passing longitudinally over rollers (1); one being motorised. Below or inside this set is another (B), the wires (5) fixed perpendicular, or inclined, to the longitudinal wires and connected to belts (4) around rollers (3), one of which is driven. The adjacent surfaces of these two sets run closely parallel to each other. The unsorted rubbish on a conveyor belt is transported close to the sieve. Here, a vacuum head is positioned, drawing air through the mesh. The light waste clings to the sieve and is transported, dropping into a hopper further on; the heavy waste falls off the belt into another hopper.
Patent DE-2550961-A1 (DE)
Title: Solid state speed controller for AC motor - with logic circuit for switching or tripping motor off
Inventor: BLOCHER REINER
IPC: H02P27/02
Filed: 1975-11-13
Abstract: The speed control circuit is for an a.c. motor incorporating anti-parallel connected thyristors in pairs, and also including in two phases additional anti-parallel pairs cross connected between phases to permit reversal of rotation. Control is extended to trip or switch off the motor using the thyristor triggering pulse generator. Additional circuits provide two functions. The gates of two phases are maintained energised in the event of a protection trip signal. This causes the associated thyristor fuses to operate and thus isolate the machine. The second function is a controlled trip in which the start up delay circuit is re-energised thus suppressing all the triggering impulses thereby removing power from the motor.
Patent DE-2553779-A1 (DE)
Title: Electric power switch for pole blocks - has polar frames on carrier bars between poles
Inventor: HOLLMANN FRITZ
IPC: H02B13/02
Filed: 1975-11-29
Abstract: An electric switch for power circuits has separate polar frames (5) on supports (4) extending from carrier bars (3). Moulded guide strips are used to fix the positions of separating plates between the polar frames and the bars (3). The separating plates, which are inserted in the swtich when the latter is open- circuited, prevent any rotation of insulating plates (9). Blocking segments are also used to prevent any insertion of the separating plates when the switch is closed. The switch has reduced dimensions along its axis.

Title: Feeding fibre bales across a mechanical plucker - withparallel guide ways holding bales in spaces of similar dimension
Inventor: KELLER ALEX JACQUES
IPC: D01G7/00
Filed: 1975-12-23
Abstract: Fibres are fed from bales of fibres to the hopper of a fibre feeding machine, by defining a bale assembly area adjacent and extending longitudinally from the hopper and determining a precise location in the assembly area for each individual bale, which is supported and mechanically confined within its individual space. The location of the confined bales is co-ordinated with the operation of the automatic machine for plucking fibres from them. The plucking machine is repeatedly, automatically and selectively moved above the bales where a given amount of fibre is removed and deposited in the hopper. Process is for uniformly positioning fibre bales within bale assembly area of a mechanical fibre plucker. Each bale is so accurately confined, fibre plucker descends into its central portion.

Title: Centre-less precision grinding machine for round workpieces - has grinding disc with steel control disc and workpiece support
Inventor: MODLER HANS DIPL ING
IPC: B24B5/22
Filed: 1975-12-29
Abstract: The machine is for centre-less precision grinding of round workpieces where there is a grinding disc, a steel central disc, and a workpiece support. The feed adjustment of the grinding disc during its usage wear takes place in a plane parallel to the connecting plane between workpiece axis and grinding spindle axis. The disc feed adjustment to balance wear takes place in a horizontal slide guide. The axis of rotation of the grinding disc is thus vertically at the axis of rotation of the workpiece. Consequently, there is no charge in angular relationships when the grinding disc is worn.

Title: Snowchain with demountable links - uses double slotted opposing coupling links bolted together to form flat rings
Inventor: SCHARFENECKER PETER
IPC: B60C27/08
Filed: 1976-02-17
Abstract: The snow chain is assembled by joining a pattern of vertically positioned grip links by a pattern of interconnecting flat rings. For a simple construction the vertical grip links are made in two halves (20, 21) of similar E shapes and bolted together in inverted setting to form closed links in each side. The flat rings are secured at each end of the double clamped links. No welding is required, with its inherent welding failures and distortions. The chain is easily repaired by unbolting the damaged and worn sections. Any worn grip links are unbolted and reversed so that the life of the chain is doubled.
