Title: Bobbin winding friction drive device - has friction devices operating in one direction to prevent oscillation increases
IPC: B65H54/54
Filed: 1974-05-31
Abstract: A constant speed drive wheel rotates the bobbin which is mounted on bearings. A rod is suspended from one pivot arm and passes between two friction stops on a bar. This bar is pivoted on a support and a spring tends to rotate it in one direction. As the bobbin diameter increases the rod is pulled through the stops. If any oscillations start to develop the friction device tends to prevent reverse movement, so damping the oscillations. A release lever and cable is used to release the friction device for adjustments etc.

Title: Inter row plough with plant stem guard bar - controlled by pneumatic piston cylinder unit and linkage
IPC: A01B13/06
Filed: 1974-11-13
Abstract: The inter-row plough is provided with a guide bar and when the stem guard bar (24) meets a plant stem, triple lever (21, 22, 23) is rotated, acting against a spring (26). By means of a lever linkage, compressed air is admitted into the cylinder (34) of a jack. The movement of the jack causes movement to be transmitted via arms (10, 11) and rod (6) causing the implement to move away to the right. When the plant guard passes away from the stem, the implement resumes its normal travel. The jack is pivotally connected to part (23) of the triple lever, a second jack being pivotally connected to the end of arm (7).

Title: Machine for dismantling oyster spar collectors - has rotating support frame with successive removal stations
Inventor: MANEO GUY
IPC: A01K80/00
Filed: 1975-03-10
Abstract: The dismantling machine holds the collectors in such a way that the strain is taken off the connecting tubes so that they may be quickly and easily withdrawn. As the machine turns about a vertical axis, several work stations can be organised at each of which one or more operations may be performed. The machine consists of a fixed cylindrical tubular frame (1) supporting a rotating head (3). Four supports (6) are arranged around the head (3), each with a horizontal arm (8) and a vertical arm (9). Arm (8) consists of two parallel tubes (10) fitting between two collector grille eyelets (11) thus holding them securely. At the first station, certain attachment fittings are removed, the machine is then turned to the 2nd. station where the connecting tubes are removed falling into passage (21).

Title: Perforated nose pressure pads for spectacle frames - provide nose aeration, enhanced aesthetic appeal and improved grip to prevent wobbling of spectacles
IPC: G02C5/12
Filed: 1975-04-21
Abstract: The nose pressure plates or pads for spectacle frames are perforated with a number of small holes (5) which have a small area.

Title: Toy monorail locomotive with cord track - has cord stretched between anchors with flat strip to prevent rolling on corners
IPC: A63H21/04
Filed: 1975-11-21
Abstract: The locomotive rides on the monorail with about a third of its height overhanging, and is moved by an internal roller running on the top of the monorail. It is stabilised against pitching by U-hoops at each end fitting loosely over the rail, and against rolling by counterweights, for which the electric motor and battery can serve if the drive to the roller is indirect. For straight stretches of monorail no more than a stretched cord is needed. For bends, a plastic strip set on edge is used. Brackets are used to support and join the plastic strip and connectors provide the transition from cord to strip.

Title: Loose intermediate layer between sealing film and substrate - with two sheets having inner slip surfaces loosely stitched together
IPC: B32B7/09
Filed: 1976-02-20
Abstract: A crack-resistant substrate is used, e.g. a building component of concrete, wood or steel lined with heat-insulating panels. The intermediate layer is two separate sheets which are loosely stitched together to allow them to slide loosely relative to each other, and which each have a slip inner surface. The outer surface of one sheet is bonded to the sealing film, and that of the other is bonded to the substrate. The slip surfaces may consist of a heat-fusible film, pref. polyester from which are produced several seam-forming connecting points between the slip surfaces by thermoadhesion. The sealing film is prevented from cracking due to stress on the substrate.

Title: Control of exposure time of photo-sensitive layer - uses series of electro luminescent diodes to indicate quantity of light received by photocell
IPC: G03B27/72
Filed: 1976-05-31
Abstract: The system for controlling the time exposure of a photo-sensitive layer includes a photoelectric cell arranged close to the reproduction field and directed towards the exposure lamp (3). The control circuit of the lamp (3) includes a variable control time switch which operates from energy supplied by the photocell in response to light received from the commencement of time control of the lamp. The photocell controls an integrator circuit which controls the excitation of successive elements (6) which indicate the quantity of light. Each of the light quantity indicating elements (6) is arranged with respect to a graduated scale (46) of time exposures corresponding to the quantity of light displayed by the element. The light elements are electroluminescent diodes.

Title: Thermal processing of high ash, solid carbonate fuel, esp. oil shale - by mixing with solid heat carrier at high temp.
Inventor: GUBERGRITS M Y
IPC: C10B49/20
Filed: 1976-06-28
Abstract: The process causes thermal decompsn. of the fuel at 475-500 degrees C, into a vapour/gas mixt. and a solid residue, by mixing with an ash-contg. heat carrier consisting of the solid residue preheated to 870-950 degrees C. Preheating the carrier increases the decompsn. of carbonates present, with formation of CaO and MgO. These combine with acid gases and vapours (H2S, CO2 and phenols boiling at >=350 degrees C) during the thermal decompsn. and reduce their concn. in the prods. In an example, oil shale of 12 mm size is dried and preheated to 120-150 degrees C with flue gas, and mixed with a solid heat carrier preheated to 870-950 degrees C. 33m3 gas contg. only 1.5 vol.% CO2 and no H2S, 13 kg. gasoline and 150 kg. resin contg. 12% phenols are obtd. per tonne shale.

IPC: A23G3/44
Filed: 1976-07-13
Abstract: Mfr. of sweetmeats based on isolated animal albumin, particularly from fish and/or other marine organisms, is described. The albumin extract, =60 pts. wt. after decongealing is concentrated to 98% solids at is not >56 degrees C followed by grinding to a molecular size of 40-60 u. Up to 50 pts. wt. prod. is opt. hydrolysed with 3.9% oxalic acid or another organic acid at 105 degrees C until >10% of the mixt. consists of long chain peptides. The thus treated albumin is mixed with =35 pts. of a confectionery fat previously heated to 56 degrees C; =35 pts. of sugar or saccharose powder, or fructose in the case of dietetic products; =25 pts. of milk powder; =1% by volume of agar-agar and also flavouring agents. The mass is then homogenised, stabilised at ambient temp. and put into the desired shape e.g. bonbons, blocks or jellies. The products are then covered with chocolate and packaged. Method gives highly nutritional products indistinguishable from sweetness bases on glucides.
