Title: Sorting machine for spindle shaped fish, e.g. herrings or sprats - for use on land or aboard ship has single multiple eccentric drive shaft and shock absorbent transmission
Inventor: SWITALA RYSZARD DIPL ING
IPC: A22C25/04
Filed: 1976-07-01
Abstract: Sorting machine is for spindle-shaped fish e.g., herrings, sprats, mackerel, of the type having a supporting stand, two sorting grids, a fish-feed device, discharge equipment and drive equipment. In the appts. (a) a sorting block is fixed by shock absorbers to a stand of any construction and height and consists of two long walls connected on the underside by profiled plates contg. similarly shaped square discharge outlets, as well as a transverse wall for fixing the drive and the upper and lower grids. (b) The individual fish guides of the upper grid are constructed as two separate halves of identical shape which when joined together approximate to flattened falling drop. (c) The fish sorting guides of the upper grid are arranged in a row above parallel transverse columns and are joined together by two connecting pieces, the front ends of which are coupled by flange clamps via two bars, two brackets as well as two jibs with bearing housings mounted rotatably on the central eccentrics of a main drive shaft; the rear ends of the two connecting pieces are connected to eccentrics mounted in fixed bearings attached to the long walls. (d) The connecting members of the lower grid are coupled with the front ends with end eccentrics on the main drive shaft, while their rear ends - analogously with those of the connecting pieces of the upper grid - are connected to the long walls. (e) The main drive shaft is common to both sorting grids and is driven via a shock-absorbing gear transmission unit from a DC or AC motor. The fish-sorting machine has a simple compact structure and a simpler drive e.g., a single main shaft with an absence of belt or chain transmission as well as possessing improved sorting elements in the upper grid not only with respect to its shape but also its method of suspension.

Title: Flexible soil auger suspension - has compression springs and adjustable stops for spatial freedom of motion
Inventor: KRIEGLMEIER EDUARD
IPC: E21B7/02
Filed: 1977-01-07
Abstract: The suspension for a mechanically driven soil auger on a drill rig frame with adjustable height is designed elastic instead of rigid so that the longitudinal axis of the auger has a certain freedom of motion in three planes. The auger is bolted to the output flange of a bevel gear which is held in a frame. Four long bolts attach the latter to the drill rig frame and stops. An elastic suspension is achieved by four compression springs, their elasticity being adjustable. The lateral freedom of motion can be varied by a set of holes for the bolts. Adjustable stops govern the clearance in the second plane. Two angle iron stops absorb the torque of the auger relative to the drill rig frame.

Filed: 1977-03-08
Abstract: The adjustable chair, especially swivel office chairs, comprises a leg frame connected to a seat support structure (2) by a support (6) which is designed as a conveyor means to raise and lower the support structure. A telescopic length-adjustable column (8) which runs parallel to the support (6) is fastened at one end (10) to the support structure (2) and near its other end (9) to the support (6) so that it can be axially displaced. At this end (9) the column (8) has a crossbeam (12) on which is mounted the adjustable foot rest (7) which tilts round an axis which runs in the direction of the crossbar. This foot rest which can be fitted to existing swivel chairs can thus be adjusted axially as well as vertically to meet the requirements of a person of any height. Since the foot rest is held stable it can act as a step to reach the seat.

Title: Film projector with manual and automatic rewind - has central switching unit with return control operating by film tension or film end detection
Inventor: EITING HELMUT
IPC: G03B21/43
Filed: 1977-05-10
