Title: Hygienic washable perspiration absorbing pillow - comprises inner water-repellant resilient body covered by absorbent layer and cover
IPC: A61F13/15
Filed: 1974-10-21
Abstract: The perspiration-absorbing pillow comprises a combination of a suitably shaped resilient water-repellant material (4) such as synthetic cotton wool and a coarser water-absorbent material (2) such as cheese-cloth which is provided on one or both sides of the resilient substance. A fine-meshed water-repellant material such as a knitted fabric is then provided on top of the water-absorbent material. In this way a pillow is produced which absorbs the perspiration from the head and allows it to dry out by means of the head or body heat. The pillow is also fully washable and quick to dry. It is suitable for bedridden people and babies and for the latter the pillow can be designed in a suitable shape, such as the face of a panda.

Title: Artificial tooth crown - made of sprayed and sintered aluminium oxide powder for better strength and wear
Inventor: NIEL BERNARD
IPC: A61C5/77
Filed: 1974-11-21
Abstract: Artificial teeth or crowns are prepared from a powder mixture with an average particle size of 25 mu and >95% Al2O3. The fused mixture is sprayed on a carrier to form a shell which is fired until the particles become agglomerated. The final shape can be given by small grinding wheels set with diamonds. This material has a higher strength than conventional materials used for dentures. It can be given any desired shape without difficulty. The white colour is compatible with denture ceramics and its great hardness results in little wear.

Title: Automatic verification system for documents - involves random scan of number of points and comparison of measured values with standard values
Inventor: TOURRET JEAN
IPC: G07D7/12
Filed: 1974-12-11
Abstract: The document verification method is used especially for banknotes, by comparing measured parameters, with ideal values of these parameters at a large number of randomly chosen points. The number of points chosen by greater than a given number to give sufficiently thorough coverage of the document, and a comparator system checks the detected valves against the correct valves for these points. The numbers of measured valves exceeding and falling below these correct values are rotated, and there are means for determining whether these valves fall within acceptable valves. The acceptable valves form a band which covers a mean valve or ideal value. Typical test parameters used may be optical transparency or reflectance.

Title: Sawtooth waveform generating cct. - consists of common emitter transistor miller integrator cct. with altered base cct. configuration
IPC: H03K4/56
Filed: 1974-12-27
Abstract: The input is a square wave of some kind and the ideal output consists of a repeated ramp waveform with very fast flyback. The capacitance is discharged through a diode rather than through a transistor base as in the Miller integrator. The effect of this is to allow the transistor to cut off immediately, giving a better flyback with a time constant dependent on the collector resistance and feedback capacitance. Two circuits are presented. In one, a single transistor is used and the feedback capacitance is connected to the junction of two diodes in series to earth from the transistor base. In the other version, three diodes in series used with a two transistor amplifier.

The apparatus contains an interrupter device and the operating cycle may be started and stopped by pushing buttons. The automatic system is designed to make a minimum demand on the technical skill of operating personnel.
Patent FR-2308833-A1 (FR)
Title: Forming hooks on ends of flat coiled springs - by using tool to cut small dia. spring turns and bend cut ends about central spring axis
IPC: F16F1/04
Filed: 1975-04-22
Abstract: A method of forming a hook on the end of a flat spring uses a machine with a solid base having a longitudinal passage which is slightly wider than the spring which is passed through the passage. In a vertical passage slides a tool which cuts the spring and then bends the ends over to form hooks. The spring is of coiled wire and has small dia. turns along one side extending into large dia. turns along the other side. The tool cuts the spring at the midpoints of two adjacent small dia. turns and bends a free end of each turn perpendicular to the plane of the spring and about the central spring axis.
Patent FR-2311732-A1 (FR)
Title: Drain plug for tank contg. liqs. which must be heated to flow - has central heating coil with valve plate opening for flow through outer annular passage
IPC: B65D90/62
Filed: 1975-05-21
Abstract: The tank has a central heating coil which reduces the viscosity of the liquid in that area. Pressure on the valve rod (F1) allows the valve (3) to open at the earliest possible moment. The hot liquid then flows down the outside of the valve through the passage (f). This flow of hot liquid causes the liquid outside the valve to heat up. Where the viscosity of the liquid in the bottom of the tank has fallen to a sufficiently low figure, the spring (22) will force the inner valve to lift thus closing the valve (3) and opening the bottom valve (2).

Title: Membrane liner retaining whey in cheese-making trough - until pulled out to permit gentle, hygienic drainage of cut curds
Inventor: GABRIEL-ROBEZ ROLAND
IPC: A01J25/00
Filed: 1975-12-08
Abstract: A membrane impermeable to liqs, e.g. rubber or plastic sheeting, is used to line the trough before milk, etc. is put in. The membrane is pulled out when the time comes to drain off the whey. Whey is pref. channelled to flow underneath the membrane on its way to the trough drain outlet. A sliding roller is pref. used to pull out the membrane. The trough is pref. fitted with horizontal and/or vertical curds cutters. The device is esp. used for mfr. of Greek Feta, Camembert, Italian Casseri, etc. Extn. of whey is accomplished as gently as by hand. Elimination of manual draining reduces labour costs, improves hygiene control, avoids loss of fats from the cut curds and prevents disintegration of the cheese mass.
