Title: Television display of musical notation - by binary signals on magnetic tape and shift register memory
Inventor: MERMET JEAN
IPC: H04N7/18
Filed: 1974-07-15
Abstract: The display system is for all forms of notation, but particularly musical notation, on some form of television screen. When the application is to a musical score it is intended that the display could run in synchronism with the music itself. The score or display required is recorded on magnetic tape in binary form, picked up by one or more 'read' heads and fed to a shift register auxiliary memory which then provides a parallel output to the main memory. Serial reading of the tape and the parallel output to the display circuits increases the speed of information displayed on the tube.

Title: Flat multicore cable looms with woven insulation - with an undulating thickness profile to preserve conductor alignment
Inventor: ROLLET M
IPC: H01B7/08
Filed: 1975-03-10
Abstract: Flat cables incorporating a linear array of conductors between sheets of insulating matl. presenting an undulating surface are described. The, undulations are caused by the profiles of internal layer(s) of insulating film woven amongst the conductors. The height of the undulations is indicative of the number of layers of insulating film between the surface and successive underlying core conductors. Esp. used for the mfr. of flat cable looms for wiring harnesses to be installed by automatic or semi-automatic equipment. The alignment of the core conductors is not disturbed by the application of the insulation. The ends of the conductors are therefore reproducibly and reliably positioned for subsequent terminal connections. Looms with analogous insulation moulded between flat platens usually feature mono- or bi-lateral displacement of individual conductors from the array plane. The height of the undulations indicates the appropriate setting for insulation stripping tools for baring conductor ends without damage.

Title: Gamma activity measurement samples transportation - involves use of pincer to lift container for movement in given track
IPC: G01T7/08
Filed: 1975-04-11
Abstract: Samples contained in bottles or test tubes for which gamma activity counts are required are moved from a transfer area to a measurement area by automatically controlled pincers which lift the sample container from one location to move it to another location. Different size containers are accepted without modification. Samples for measurement are contained in test tubes (60) in load carriers (10) which hold a number of tubes of different sizes. The number of tubes is counted by an optical circuit. The load carriers are moved in the required direction (f), by push rods in a step by step action. The sample containers are removed from the carriers by the jaws of a pincer (24) which moves in a predetermined track (30) to a well (27) where the container is released.

Title: One piece permanently fitted stopper for tubular container - is opened by rotating cap to line up holes in cap and extension of container
IPC: B65D47/26
Filed: 1975-04-17
Abstract: The permanently fitted stopper is for a metallic tube container, for use with viscous liquids. The device is in the form of a one piece moulded plastic cap fitted over an extension of the metal tube. The plastic cap has a reduced thickness section and an extension by which the reduced thickness part can be torn off. There is a hole in the metal tube extension, and the liquid is poured through the two holes. The plastic cap is fixed permanently on the tube by internal circumferential ridges which engage in corresponding grooves on the tube. The cap can be rotated, so that the holes in the cap and the tube are misaligned, sealing the container. The holes can be rectangular, circular, etc. depending on the liquid contents.

Title: Acoustic vibration generator for liquid current - has cylindrical rotor with closed ends and inlet for liquid
IPC: F15B21/12
Filed: 1975-05-13
Abstract: A hollow cylindrical stator in the working chamber has a series of orifices in its side, and accommodates a coaxial rotor coupled to the drive and with orifices in its side one whole number more than those in the stator. Whenever the two sets of orifices coincide, liquid arriving in the rotor passes into the chamber. The rotor is a cylinder with closed ends, one having an opening for the passage of liquid to its interior. The size of the orifices in rotor and stator is determined by a formula taking account of rotor angular velocity and external radius, and the speed of propagation of sound into the liquid.

Title: Acylation of amines and alcohols - for use in pharmaceutical analysis, using a lyophilised carboxylic anhydride
IPC: G01N33/531
Filed: 1976-02-05
Abstract: Acylated derivs. of prim. or sec. amines or of alcohols, suitable for analytical purposes, are pred. using carboxylic acid anhydrides in stabilised form prepd. by lyophilisation of a soln. of a cyclic anhydride, esp. succinic anhydride, i a lyophilisable solvent such as dioxan or THF. The lyophilisation process allows small quantities of the anhydride to be measured precisely. The anhydride is in a more reactive form than conventional crystals. The acylation process is cheaper to carry out and gives better yields than conventional acylations. In an example, the 2'-o-succinyl deriv. of adenosine 3',5'-cyclic monophosphate was prepd. in 100% yield from 10 mg of adenosine 3',5'-cyclic monophosphate and 45 mg lyophilised succinic anhydride in water.
