Title: Vehicle acceleration measurement device - records time elapsed during which velocity variation changes by fixed amount
IPC: G06G7/184
Filed: 1974-01-11
Abstract: A memory (C1) records the initial value of the velocity (Vo) at the commencement of the time measurement. A comparator (A2) provides the velocity variation (DELTA V) by subtracting the initial value (Vo) from the current value (V). A differential comparator (A3) determines the sign of the variation (DELTA V). A system (R) conveys the absolute value of the velocity variation (DELTA V) to a second comparator (A4) which compares this with a fixed reference value and initiates, via a bistable circuit (Bi), the stopping of the time measurement by counter (CH) when the two values are equal. A memory records the time measured in order to feed it to control and regulation equipment during the subsequent measurement operation. There is also a system of sequential command for the reading operations.

Title: Projection photolithographic process for producing LSI circuits - involves step and repeat exposure for minimum distortion
IPC: G03F7/20
Filed: 1974-03-25
Abstract: The master and prepared sample are held in a special equipment which exposes only part of the sample at any one time. After exposure master and sample are moved in a step and repeat manner so that all parts of the sample are exposed. The process eliminates the field distortion at the edges of the projection process and enables the fine detail required for LSI circuits to be accurately reproduced. The optic system has a beam splitter so that part of the beam is taken to a monitor which ensures that every part of the sample is exposed with the same intensity. The process enables the advantages of projection exposure to be applied to high resolution repeated patterns.

Title: Truncated pyramid stackable storage bin - has bars mounted across top, to pivot for stacking or fitting
IPC: B65D21/06
Filed: 1975-06-20
Abstract: Storage bins with a truncated pyramid shape, can either be fitted one inside the other or can be built into a pile when full. The bins have two long and two short sides, and two cross-bars (11) are mounted across the top of the bin. The bars are in the form of a U, and are mounted so as to pivot (13, 14) about an axis parallel to the short sides. If it is wished to fit bins inside each other, the bars are pivoted outwards. This removes all obstruction from the opening. The bars and pivots are arranged so that in this position they do not project significantly beyond the sides of the bin. When pivoted to the inner position, the bars act as supports for a super-imposed bin. In this position the bars have a horizontal support strip and a vertical strip which guides the feet of the upper bin.

Title: Digestible protein from proteinaceous materials, e.g. raw fish - by partial hydrolysis with organic acids after comminution (NO280676)
IPC: A23L17/10
Filed: 1976-01-08
Abstract: Proteinaceous raw materials of animal or vegetable origin are treated for the recovery of >=93% of the digestable material by (a) breaking up the hard fibres or bones into particles of 1 mm dia. and (b) hydrolysing the comminuted material with an aq. soln. of >=1 organic acid to such an extent that the hydrolysate after filtration through a 40 mesh sieve comprises >=70% of the raw material broken down to molecular size or converted to an aggregated molar suspension and that is not>10 wt.% of the raw protein is present in the hydrolysate as free amino acids. Previous processes of this type resulted in hydrolysis to individual amino acids and also led to large amts. of ash in the prd. Use of enzymes as an alternative method of hydrolysis also led to individual amino acids alone or in admixt. with chain-crosslinked amino acids. The invention enables digestable protein to be obtd. directly.
