Title: A device for limiting relative rotation of two coaxial bodies
IPC: B66C23/94
Filed: 1979-02-27
Abstract: A first body 7 which may be part of a crane is driven in rotation relative to a body 1 through a lost motion device and, for example, by a pinion 3 engaging with a toothed rim 2 attached to the body 7. The lost motion device may comprise lugs 10 and 11 fixed to the bodies 7 and 1 respectively, and a freely rotatable arm 9 mounted coaxially of the two bodies.

Patent GB-2045854-A (GB)
Title: Cylinder locks
IPC: E05B21/06
Filed: 1980-03-14
Abstract: A cylinder lock includes two barrels (23, 37), a first (23) carrying tumblers (30) that abut internal shoulders (36) of the lock casing (2) to obstruct clockwise 'unlocking' rotation only, and the second (37) carrying a single tumbler (43) which obstructs only counter- clockwise 'locking' rotation by abutment with a shoulder (48) of a rear-end casing-cover (8). A key (5) inserted through a keyhole-defining assembly (11, 16, 21) withdraws the first-barrel tumblers (30) during initial clockwise turning from the insertion position, and the second-barrel tumble (43) during initial counter-clockwise turning. Lost- motion coupling between the barrels (23, 37), provided by lug-in-slot (38, 39) interengagement, enables clockwise turning of the second barrel (37) with the key (5) relative to the first barrel (23) during withdrawal of the first-barrel tumblers (30), and corresponding counter- clockwise turning of the first barrel (23) relative to the second (37) during withdrawal of the second-barrel tumbler (43). Lug-in-slot coupling (22, 24) between the keyhole-defining assembly (11, 16, 21) and the first barrel (23) similarly allows initial slip for clockwise key-turning. A coiled spring (42) opposes resiliently second-barrel turning in both directions. <IMAGE>

Title: Method of Producing Fibre Ribbon From Fibre Crops and a Machine for Carrying Same into Effect
IPC: D01B1/14
Filed: 1980-04-02
Abstract: A single layer of longitudinally arranged stems of fibre crops is formed, whereupon said layer performs continuous movement during which the stems are dried, broken and stripped of scutch. The process of stripping the stems of scutch incorporates the operations of scutch crushing, separation from the stem fibre and scutch disposal, scutch crushing and separation being carried out by longitudinally compressing the stems in the layer. In the machine for carrying out this method the device 4 for scutch crushing and separation from the stem fibre comprises the straight-through chamber 14 having its cross-sectional area narrowing towards the direction of movement of the layer of stems. Provided at the inlet opening 15 of the chamber 14 are the feed rolls 16. Thus, the yield of long fibre is increased and the amount of scutcher waste is reduced. <IMAGE>

Pillars (24) provide a guide for the edges of the plies and are disposed parallel to the direction of feed. Instead of regions of rubber and P.T.F.E. the plates (13, 15) may have suction or pressure air applied thereto to force the plies into pressured contact with the plates in the regions of greater feed resistance. <IMAGE>

Title: Fibre-reinforced composite shaft with metallic connector sleeves
IPC: F16C3/02
Filed: 1980-05-28
Abstract: A tubular fibre reinforced composite shaft integrally incorporates a metal sleeve or connection at the end. Initially a metal sleeve 14 having knurls on its outer surface is positioned upon a segment of a mandrel. Fibrous material bearing a non-solidified resinous material is applied around the mandrel and around the knurls and is locked between spaced knurl projections. Additional fibrous material bearing the non-solidified resinous material is applied to the previously applied material. The resinous material next is solidified to form a tubular composite shaft whereby a secure torsion- transmitting connection is made with the sleeve, and the mandrel is removed. Alternatively, an outer sleeve can be inserted after the additional fibrous material has been applied to the first-named sleeve. The outer sleeve has knurls on an inner surface thereof and is pressed against the fibrous material as by swagging. Cuter ends of the inner and outer sleeves are welded together after the resinous material is solidified. <IMAGE>

Title: Radio receiver with search tuning
IPC: H03J1/00
Filed: 1980-11-17
Abstract: A ratio receiver, in particular a car radio receiver with automatic switching between different stations transmitting the same program. This receiver is tuned to a reference station transmitting the desired program and being located in a predetermined receiving range. This receiving range is furthermore scanned for looking for relay stations transmitting a signal having the same program contents as the reference station. The tuning data for both the reference station and the thus found relay stations are stored in a memory. From these stored tuning data those data are selected in a search tuning operation which correspond to the station causing the highest field strength at the receiver input. When this field strength decreases to below a selected level, another tuning data is selected in the search tuning operation, which then corresponds to the station having the strongest field strength at the receiver input.
