Title: Hospital bed mattress to prevent bedsores - having deep foam mattress partially cut in sections and loose cover
Inventor: BLAIR EDGAR ALLAN
IPC: A61G7/057
Filed: 1975-07-07
Abstract: The mattress to prevent bedsores has a one piece body of elastic foam material which is thicker than the average patient and to compress it by 50% requires a pressure equal to the body weight of the patient divided by the surface area of the body in contact with the mattress. The mattress is divided into several individual weight bearing elements and covered by a flexible, waterproof, soft but durable material. The cover (24) is loose enough not to pull tight when the patient sinks deep into the mattress. The mattress can be made rigid enough to move the patient about on by tightening up the cover using side straps (26, 28) on two edges buckling (30) together below the mattress. A shaft is provided beneath the mattress around which the straps are wound and a handle used to turn the shaft for mutual adjustment of all the straps at once. Prefan electromotor turns the shaft.

Title: Automatic roller shutter operating mechanism - uses heating system with thermostatic time switch control for day and night operation
Inventor: GAUSEPOHL THEODOR
IPC: E06B9/70
Filed: 1975-07-25
Abstract: The purpose is to provide a window-darkening and protective lowering mechanism for roller shutters, enabling this movement to be controlled even during the absence on holiday of the householder. The shutter is opened by day and closed by night, but without recourse to additional expensive time-switches or sensors. The roller shutter (4) is controlled by the time-switch of the thermostat circuit in a heating system. This may be effected by turning over from day to night operation at the same time as the timeswitch, or vice-versa. Where there are several shutters, some may be operated on a delayed timing setting. The control may also be carried out independently of the heating system.

Title: Reducing hair damage on bleaching and dyeing - by adding azacycloalkane-(2,2)-diphosphonic acids, salts or esters
Inventor: REESE GUENTER DIPL CHEM DR
IPC: A61K8/55
Filed: 1975-11-04
Abstract: Hair damage on bleaching and dyeing with active O-releasing cpds. is reduced by using a compsn. contg. azacycloalkane-2,2-diphosphonic acids having formula (I). (where is no. 3-5. R is H or 1-3C alkyl), or their water soluble salts or esters (I) may be admixed to a vehicle, soln., gel, cream or powder, or used in combination with oxidising agents, or added to a rinsing- or washing compsn. Pref. (I) used are azacycloheptane-2,2-diphosphonic acid and its water-soluble salts, esp. the Na-, K-, NH4- or ethanolamine salts. Hair treated has high gloss, better hand and good elasticity. Hair damage is prevented more effectively than when using 1-hydroxyethane-1,1-diphosphonic acid (II) as active material for reducing damage to hair, E.g. with addn. of 0.1% azacycloheptane-2,2-diphosphonic acid, alkali solubility of hair on bleaching is increased by only 3.8% compared with 6.2% on using 0.1% (II), and with 10. 2% without an additive.
Patent DE-2550348-A1 (DE)
Title: curing system for continuous wire lacquer or plastics coatings - has max. heat transfer encouraged by deflection system for hot gas flow
Inventor: PUEHSE WOLFGANG DIPL ING
IPC: B05D3/02
Filed: 1975-11-10
Abstract: The convectional heating system used is constructed such that to raise the heat transfer from the hardening or baking of gas flow to the surface to be dried, the gas or exhaust air flow is deflected by a right angle to the original flow direction. The hot air then flows over the surface to be dried and is eventually deflated away down an exit pipe. The arrangement enables the curing time to be relatively short and the length of the curing oven also to be relatively short, so that high throughputs can be achieved.
Patent DE-2554604-A1 (DE)
Title: Trailer for transporting containers - has U shaped frame with holding pins at corners and open rear for fork lift access

Title: Thrust deflecting flaps for STOL aircraft - with secondary flap extending upwards to deflect engine thrust downward for extra lift
Inventor: SADOWSKI HERBERT
IPC: B64C9/20
Filed: 1975-12-06
Abstract: The trailing edge of the wing has a compound flap with a main flap which is tipped downwards and rearwards by a servo motor and a thrust strut acting on four linked levers. The flap has a support brace on which a secondary flap slides longitudinally upwards above the level of the wing to deflect the thrust from the engine above the wing. The system provides added vertical thrust for STOL aircraft. If the engine fails then the main flap can be set in a greater droop setting for the extra vertical thrust, with the other engines powering the aircraft.

Title: Chassis fitting vehicle lifting jack - has boss fitting closely inside swing arm and slightly smaller than opening in chassis
Inventor: HAFNER FRANZ
IPC: B66F3/08
Filed: 1975-12-22
Abstract: The vehicle jack has a supporting column on a foot and containing a crank-operated screwed spindle, actuating via a nut a swing arm with a boss at the free end fitting in the underside of the vehicle coachwork. A stop is provided on the underside of the arm to limit the amount for which the boss is inserted. The boss fits closely inside the arm as far as a point level with the end face of the stop. The distance between two parallel tangents, one at the bottom of the forward end of the boss, and the other at the top of the boss where it is enclosed by the forward end of the arm, is slightly less than between the tangents to the top and bottom half-shells (70) in the chassis which between them form the opening for the boss. These are offset in relation to each other in the lengthwise direction.

Title: Drum winch with self locking worm drive for boat transporter - has worm on manual crank axially movable to engage gear
IPC: B66D1/14
Filed: 1976-02-27
Abstract: The drum winch with a self-locking worm drive for a boat transporter comprises a worm which moves axially between positions engaging with and disengaged from the worm gear of which the engaged position is fixed by an axial stop. The direction winding of the cable on the drum is such that the circumferential force of the worm gear caused by the load moment biasses the worm when in the engaged position against the axial stop. The axial stop consists of a bearing for the worm shaft which is axially displaceable, which bears a hand crank lever and on which the worm is mounted rigidly.

Title: Low sulphur fuel gas prodn. from fossil fuels - with addn. of iron oxide before, during or after gasification
Inventor: WEISS WOLFGANG DR
IPC: C10J3/08
Filed: 1976-05-03
Abstract: Prodn. of low-sulphur fuel gas comprises gasification of fossil fuels in which iron oxide is added before, during or immediately after gasification. Contact between gas and iron oxide is pref. at >600 (900 degrees)C up to gasification temp. Amount of oxide used is pref. 10-100% in excess of the stoichiometric quantity for complete reaction of sulphur present. Atmospheric pollution is reduced by a simple process using existing gasification plant, needing only the addition of equipment for feeding the iron oxide. The iron sulphide formed can be removed in molten form with the usual slag, and can be regenerated for further use by roasting in air. The gas does not require cooling, allowing use of its full heat content. Well over 90% of the S is removed.
