Title: Analogue-digital converter using operational amplifier - for pulse code modulation telephone signals
IPC: H03M1/14
Filed: 1973-09-06
Abstract: The operational amplifier (5) has a gain factor greater than one and receives a pulse whose amplitude is converted and integrated in a negative feedback loop, including comparators (15-21) with fixed threshold values and a current injector (23). An odd number of comparators, (15-21), connected in parallel are used, each having a different threshold value in accordance with a linear equation. The current injector (23) is controlled by the outputs of the comparators (15-21), with means (12, 13) for feeding the amplifier output signal back to a positive input of the amplifier (5) in synchronism with signals from a clock source (24). The amplifier gain factor is an integer, one greater than the number of comparators employed. A logic network (22) between the comparators (15-21) and the current injector (23) transforms the comparator output signals into a binary code.

Title: Turbocharger for automobile diesel engine - has bypass from compressor discharge to turbine inlet to control output
IPC: F02B37/12
Filed: 1974-04-17
Abstract: Fresh air enters the inlet (7) of the compressor (6) which discharges through a pipe (4) into the engine inlet manifold (2).

Inventor: SUPRIN JEAN
IPC: C10C3/00
Filed: 1974-06-24
Abstract: Bituminous binders, for making water-tight matls., are prepd. by (a) oxidising a bitumen, (b) diluting the oxidised bitumen with an aromatic extract, and (c) regulating the degree of oxidn. and the amt. of diluent so as to adjust the penetration and the softening point of the final binder.

More esp. the substrate is impregnated with a road-type bitumen binder, of relatively high penetration, and surfaces with a hard bitumen binder, of low penetration. The properties of the binder are easily adjusted. Matls. of low softening point, which are easily compatible with prods. of high softening point and low thermal sensitivity, can be obtd. Sweating of the diluent from prods. of low penetration and high softening point is much reduced.

Title: Pressure die casting metals with high m. pt. - involves altering shape of die cavity to avoid hot tears
IPC: B22D17/22
Filed: 1975-02-27
Abstract: A process for the pressure die casting of metals with a high m.pt. (e.g. iron metals) using a two-part permanent mould where the casting produced has a central section with a longitudinal axis plus at least two transverse sections so that the central section is subjected to stresses during cooling (i.e. constraint). The mould cavity is provided with 'anchors', so arranged that when stress arises during solidification and cooling, due to the constraint created by the transverse sections, the central section of the casting is not free to move along axis, thereby preventing or reducing hot tears and/or die-wear. The pref. method consists of using a die provided with subsidiary cavities and/or projections, which break up a long straight section or permit stress-redistribution.

Title: Application of spiral reinforcement to the outside of a plastic tube - keeping the windings under tension to prevent compression of the tube
IPC: B29C48/09
Filed: 1976-01-21
Abstract: In the continuous application of a spiral reinforcement to the outer surface of a plastic tubular substrate, using monofilaments, strips, wires etc., wound on bobbins as reinforcing members, the reinforcement is applied continuously to a stationary tension-unloading element via a revolving reinforcement take-off member coupled with the bobbin dirve and rotating at a speed, which in conjunction with the speed of advance of the tubular substrate determines the pitch of the winding, the reinforcement then being transferred continuously the tubular substrate which passes through the tension-unloading element and wound there on free from tension and distortion at the pre-selected winding pitch. Advantageously, the reinforcing material is heated prior to its application on the tube to relieve its internal stresses. Used particularly for thin-walled tubes. The tension in the reinforcing windings is prevented from compressing the tube and altering its internal dia.
