Title: Refrigerator construction process - uses wall components with steps formed in plastic foam along lengthwise edges
IPC: F25D23/06
Filed: 1973-12-07
Abstract: The walls of the refrigerator are thermally insulated by a thickness of plastics foam formed in situ.

Title: Trigger for underwater harpoon gun - has pivot rod retaining harpoon, holding elastic band and held by safety catch
IPC: F41B7/04
Filed: 1974-04-11
Abstract: A tube (1) houses the harpoon. A strong elastic band (17) which fires the harpoon is held stretched at the rear of the tube, with a finger loop attached to it at that end, and is retained at the other end by the trigger (6). This trigger has a step in the middle to hold the elastic band, and immediately behind is a pivot rod about which the trigger swings. In the loaded position, a downturned flange on the front end of the trigger engages a notch (11) in the harpoon, while an upturned flange at the other end protrudes through a slot (16) in the tube, and is held up by a safety catch (14). This safety catch is a bent wire which, when released, allows the trigger to swing down and release the harpoon.

Title: Linear motor vehicle - inductor guided each side of vertical track permitting sway
IPC: H02K41/025
Filed: 1974-06-20
Abstract: A linear induction motor (10) has a vertical inductor with two faces acting on a vertical plate on a track, with guide rollers (30) running free on vertical axes, positively located relative to the vertical plate. The vehicle is guided independently and can move without affecting alignment of the inductor.

Title: Bottle cap printing process - transfers pigment in hot process from evenly impregnated strip
IPC: B41F17/16
Filed: 1975-02-19
Abstract: The process is for printing a mark, such as an excise stamp, on a bottle cap. A pigment is transferred hot from an evenly-impregnated strip. The equipment can include means for cheking that a cap is present, and the pressure and temperature of the transferring element, after which the latter is thrust downwards to press the strip against the cap. It can typically be in the form of a moving punch with an embossed die (37) acting against the cap (4) on the bottle. The presence of the cap can be detected by a device not reacting to the presence of glass, and the strip tension can be picked up by an arm actuating a microswitch. A pressure gauge can be used to check the punch pressure, and a thermostat for the temperature checking.

Title: Simplified equations for logical automation - are investigated by series of inputs for determined variable and connection method to source and summation unit
Inventor: MATROT PIERRE
IPC: H03K19/173
Filed: 1975-04-01
Abstract: For each control element or each operation the prohibited combinatory possibilities are determined. The apparatus has a supply source, a series of inputs and switches and logic calculating means. The inputs are each associated with a variable determined from the problem in a determined state. The switching circuits are used selectively to connect one or several inputs to the source. The logic circuits are each associated with a determined combinatory possibility and connected to the inputs, each corresponding to a variable in a state complementary to that of the variable in the combinatory possibility. The logic permits one to ensure that for each prohibited combinatory possibility, the logic sum of signals presented to the inputs is equal to 1.

Title: Curing system for aminoplast adhesives - consisting of aq. soln. contg. group I-II-ammonium salt and different metal salt
IPC: C08K3/00
Filed: 1975-04-17
Abstract: Curing system for adhesives based on aminoplast resins e.g. for laminates, consists of an aq. soln. contg. (I) a water soluble ammonium salt, or sulphate or phosphate of a group I or II metal, and (II) a hydrolysable, water soluble salt of a metal that is different from the metal in (I), the wt. ratio of (I)/(II) being 5/95-97.5/2.5, esp. 20/80-90/10. By correct choice of the proportions of (I) and (II) the pot life of the adhesive can be controlled over a wide temp. range. (I) and (II) have a synergistic curing action, and can be added to the resin immediately before use, i.e. to provide a very short pot life.

Title: Speed control for electric traction - with mechanical linkage to belt or disc transmission and electric speed control
IPC: B60L11/18
Filed: 1975-06-17
Abstract: The output shaft of the electric motor (1) has a pair of discs (8, 9) mounted on it with the outer disc (9) moved axially by a sleeve. This alters the point at which a belt drive (11) rides between the discs. The sleeve is moved by a linkage to the accelerator pedal (5) while another linkage from the pedal operates on a speed control (4) for the motor. The belt drive is transmitted to the wheels via several spring loaded sets of discs and belts. The system provides a simple control for the electric traction without complicated electronics.

Title: Removing mono- and/or di-isocyanates from gases - by washing with water, dilute alkali or dilute acid
IPC: B01D53/54
Filed: 1975-07-18
Abstract: Mono- and/or diisocyanates (e.g. hexamethylene diisocyanate) are removed by hydrolysis from gases or vapours contg. them by washing the gases or vapours with water, dilute aqs. alkali or dilute aqs. mineral acid in the presence of active charcoal and/or active alumina. Removal of toxic-mono- and diisocyanates (used e.g. in the prodn. of polyurethanes and in the textile, rubber, detergent and pesticide industries) from gases and vapours contg. them by hydrolysing to the corresponding mono- and diamines. Hydrolysis in the presence of active charcoal or alumina prevents the deposn. of polyureas or ureas, so that the process can be operated continuously for long periods of time. With isocyanate concns of up to 20g/Nm3, a single wash can reduce the concn to 0.02 ppm to the limit of detection. With gases and vapours contg. more than 20g isocyanate/Nm3, a single wash can reduce the level to ca 0.05 mg/Nm3.

These forwarding mechanisms for the wood-chipping machine are mounted adjoining the exit from the bark-stripping machine. The bark-stripper may be mounted movably lengthways and crossways, so as not to exceed the prescribed vehicle max. dimensions. The forwarding mechanisms may not exceed 60 or 70% of the length of the longest tree-trunks.

Title: Two-way stretch fabric comprising gauze with inverted binding - for moulded foundation garments providing support without excessive pressure
IPC: D03D17/00
Filed: 1976-05-25
Abstract: A woven fabric which can be stretched along two axes at right angles to each other, is produced from weft, at least one thread of which is inextensible, and warp threads which are extensible. The fabric is in a gauze construction with inverted binding. Whilst at least one thread of the weft is unstretchable, a number of warp threads are extensible. These elastic threads may have a core of an elastomer, and the elastomer core may be sheathed in a winding thread or threads. The inextensible thread may be of cotton or of a synthetic such as a polyester. When removed from the loom, the fabric retracts to two-thirds of its loom size, whilst after boiling it is reduced to only fifty percent of its loom size and has a coefficient of elasticity of practically 100%. The fabric obtd. is shaped in three-dimensional moulds to form the foundation garment sections.

Title: Shaft seal for underwater machinery - uses annular screen formed by jet of fluid delivered via toroidal chambers
Inventor: POUPEL PIERRE
IPC: B63B59/10
Filed: 1976-09-07
Abstract: The rotating shaft (36) passes through the chamber (35) which is immersed in water (32) and contains air under pressure. To prevent the leakage of air a screen of fluid is produced around each outlet (14). High pressure fluid is supplied by the pipes (31A, 31B) to the tor. (19e. The fluid flows out through holes (24) into annular chambers (23) and then through a narrow annular gap (21) between the tubular ring (18) and the edge of the hole (14). The fluid issues from the gap (21) in the form of a circular screen which prevents the outward flow of air from the chamber (35). At the same time the shaft (36) can move laterally or axially or it can rotate without being restricted by friction.
