Title: Fixing hook for extendable ladder - comprises two armed lever with spring return and displacement control by holding tooth
Inventor: HYMER ERWIN
IPC: E06C1/12
Filed: 1975-04-28
Abstract: The fixing hook for extendable ladders is shaped like a lever with two arms and is attached to the inside surface of one of the uprights of the ladder section. One arm connects with a rung of the upper section to prevent the lever from rotating and the other transmits the load between the lever axis and a rung of the lower section. A holding tooth (27) is also attached to the upper section and controls the angular displacement of the lever (25). It is linked to the arm (13) which prevents rotation of the lever by a tension spring (18) so that when the tooth swings outwards, it pulls the su ppot surface (11) of the arm (13) against the upper surface of the rung (8) of the upper part of the ladder, while when it swings inwards, it acts on the arm (14) which transmits the load to remove the support surface (11).

Title: Aligning two pipes for butt welding, using expanding mandrel - to obtain smooth bore for pneumatic conveying of fragile goods
Inventor: PRETO NORBERT MAURICE
IPC: B23K37/053
Filed: 1975-10-27
Abstract: Two pies are centred and aligned by an expanding mandrel prior to being joined by butt welding. Process comprises: (a) expansion of the mandrel until it meets the pipe with the smaller dia. and provides pipe with a circular cross-section; (b) conversion of a second pipe to a circular cross-section, and/or expansion of pipe, depending on the ovality of pipe and the diametrical tolerances of pipe; (c) combined expansion of the two pipes is finally efected. The expansion may be carried out via a work cylinder, the expansion being limited by a safety valve on a pump feeding the work cylinder. Alternatively, expansion may be continued until >=1 pipe is forced against an outer reinforcing ring. The pref. mandrel uses expanding segments fitted with Cu pads pressed against the pipes. Method may be used e.g. for welding pipes used as pneumatic conveyors in hospitals etc. for bottles of blood or medicines; or for conveying powders. No surface roughness or weld metal is present in the bore of the pipes at the welded joint, i.e. there is no interference with the travel of conveyed objects.

Title: Stepless variable speed drive for automobile - has secondary disc springs mounted on axial splines to eliminate shock when braking
IPC: F16H13/14
Filed: 1976-04-06
Abstract: The stepless variable speed drive for an automobile has an input shaft (4) provided with coned discs (2) mounted on axial splines (5). The outer edges of the discs (2) are pressed between rings (3) which slide in splines (8) in the housing (7). The output shaft (13) is provided with a flange (12) which is pressed against the disc by springs (14) acting on toothed ring (17). The speed ratio of the drive is changed by shifting the input shaft sideways w.r.t. the axis of the output shaft (13). The smaller disc springs (23), reduce the shock when the engine is used as a brake and the output shaft drives the input shaft (4).

Title: Deep freezing edible liquids or fragmented solids in sachets - by immersed progression through liq. refrigerant as individual sachets or continuous chain of pockets
Inventor: SANDSTROM PER
IPC: B65B63/08
Filed: 1977-04-01
Abstract: The process is of the type in which a measured vol. of prod. is sealed inside a deformable envelope prior to freezing. The deformable envelope is now tubular and is divided by transverse seals into a pocket, each contg. a measured vol. of prod. The filled pockets can be sepd. bny cutting through the transverse seams to produce individual pockets for freezing. Alternatively, the pockets can be left in a continuous chain which is drawn continuously through refrigerant liq. for freezing. Individual pockets are pref. conveyed through a freezing tank by a current of liq. refrigerant. Depending on whether the pockets tend to float or sink in the refrigerant they are advanced along a partly submerged, rising or falling, inclined plane. When the pockets are left in a continuous chain for freezing, they are pref. carried through the liq. refrigerant on the circumference of an immersed, rotary drum. Used for freezing liq., semi-liq. and fragmented solid food prods. e.g. spinach puree, mixed vegetable salad. A single, simple installation handles both liq. and solid prods. in individual portions or bigger packs.

L-amino acids (opt. partly replaced by the corresp. keto and/or hydroxy acids) and/or their salts, and 97- (pref. 5-20) pts. wt. of a neutral-tasting pharmacologically compatible and/or enzymatically metabolisable fat component with a softening point of 30-70 degrees C (pref. 37-56 degrees C). The amino acids pref. include all of the essential amino acids, and opt also non-essential amino acids. The fat component can comprise one or more fatty acids and/or their salts and/or esters, esp. mono-, di- or tri-glycerides, or it can be an enzymatically metabolisable synthetic resin, e.g., a polymethacrylate with pH-dependent solubility. The granules can be used in the treatment of kidney and liver disorders and post-operative uremia and have no unpleasant taste and are less bulky and thus easier to take than tablets.
Patent FR-2389050-A1 (FR)
Title: Rectilinear to rotary motion converter - uses two sliding toothed racks engaging two toothed wheels alternately
IPC: F16H19/04
Filed: 1977-04-25
Abstract: The mechanism for converting rectilinear motion to rotary motion has a shaft (13) which carries two toothed wheels (3, 4) mounted side by side. The teeth on each wheel are divided into two zones consisting of two diametrically opposite arcs of 90 deg. and the teeth of one wheel are staggered wrt the other. The two toothed racks (1, 2) engage the teeth of the wheels. The racks are moved in the one direction by the source of power and are returned by springs (9). The racks move alternately, so that as one rack drives one toothed wheel the other rack is returning with its teeth disengaged. There is less power lost due to friction with this mechanism than with a conventional piston and crankshaft.
