Title: Ball cartridge for sporting and hunting - fires spherical projectile and can be used in standard calibre guns
IPC: F42B7/10
Filed: 1974-07-10
Abstract: The projectile, being spherical in shape, has minimum deviation and gives high precision results in the hunting of large and medium game. Its form offers little resistance to air flow, giving it speed and power. The ball is fitted into a case or sleeve, this forming the wad, guiding the ball up the bore of a gun barrel. Different thicknesses permit several calibres to be used in the same gun. The ball is not deformed and the sleeve can be used in choke bores or parallel bores. Friction is reduced during the passage of the ball, leading to reduced wear of the bore.

Title: Mercury removal from liqs - by amalgamation with solid reducing agents e.g. iron and copper
Inventor: PORTES PIERRE JACQUES
IPC: C02F1/70
Filed: 1974-11-18
Abstract: Mercury is eliminated from liqs. by passing the latter over a solid metallic reducing agent e.g., Fe or Cu for a contact time sufficient for all the mercury to accumulate on the reducer. The amalgam adheres to the reducer and the mercury is extracted by the usual methods. Contact with the mercurial liq. is maintained for two mins. to three hrs.; some 99.5% of the mercury is eliminated. In another method contact between the reducing agent and the liq. is effected either in a tank or trough or in a column with the inlet for the liq. at the top, so that the reducing metal is constantly immersed in the liq. Such an arrangement can continue to work for at least three months. The method is simple and gives a high yield of mercury; no filtration is required and both the mercury and the reducing metal can be recovered by distn.

Title: Interface circuit for motor vehicles - blocks spurious effects on input signals to digital cct. using filters flip flop and oscillator
IPC: H03K3/013
Filed: 1974-12-30
Abstract: The inferface circuit, for motor vehicles, avoids spurious effects in an input signal from reaching digital circuits. The input signal is passed via an RC low pass filter to a high input impedance amplifier (6). The amplifier output is differentiated (7, 8) amplified (9) and applied to a bistable circuit (10). The bistable circuit output is low pass filtered (14, 15) and used to control an oscillator (12). The oscillator output is fed back (11) to the bistable circuit and over an amplifier (13) to the output (16). The input to the oscillator consists of a voltage that is proportional to the phase difference between the two inputs to the bistable circuit.

Title: Sprag or raking strut for shutter panels - has horizontal brace to support both back and front
IPC: E04G19/00
Filed: 1975-01-09
Abstract: The sprag or raking strut is for use with shutter panels, and has at least one leg (6) and a brace (7) which links the base of the leg (5) to the base of the shutter (1) panel to prevent it from falling over. The brace (7) has a cross-piece (12), the front end of which fits exactly into a hole (13) in the shutter panel so that the brace can be slid forward through the hole to rest on the ground in front of the shutter to prevent the panel falling forwards during erection. Only one sprag is needed to support both the back and front of the shutter wall and the fact that the cross-piece can be drawn back flush with a shutter wall means that no marks will be left in the concrete once the shuttering is removed.

Title: Digital error rate measurement using auxiliary channels - has each channel with regenerator and signal generator with related error rates
Inventor: MAUREL VINCENT
IPC: H04L1/24
Filed: 1975-07-09
Abstract: The error measuring system, for digital transmissions, uses auxiliary channels each provided with an auxiliary regenerator associated with a signal generator. The last signal generator output is such that the output of the last regenerator has an error rate that is a function of the error rate of the output of the first regenerator and of a parameter associated with the last signal generator. A comparator compares the output of adjacent regenerators. The advantage of this method lies in its being independent of transmitted signal and in being quicker than existing methods using test signals or redundant signals.

Title: Press for making slots in armature lamellae - has program controlled actuating drive for curved path
IPC: B21D28/22
Filed: 1975-07-10
Abstract: The press is used for making slots into armature lamellae of electrodynamic machines. These lamellae are in the form of circular segments for large size armatures. The machine has a slide which is moved step by step on a curved guide, which is actuated by programmed step motors so that the drive does not need adjustment when changing over to different lamella sizes. The driving spindle of the curved slide is powered by at least two electronically controlled step motors (24, 29) with sufficiently small step size. The first motor (24) rotates the spindle directly and the second motor (29) superposes a longitudinal movement on the spindle for obtaining curved and indexing movement.
