Title: Thermochemical treatment of metal with ion bombardment - using a sealed discharge chamber, an electrode support and an arc detecting generator
Inventor: GANTOIS MICHEL GASTON
IPC: H01J37/32
Filed: 1975-01-17
Abstract: Superficial thermochemical treatment of metallic pieces is effected by ionic bombardment, the pieces being arranged in a sealed metallic chamber contg. a reactive atmosphere of predetermined compsn. and pressure, and at a cathodic potential of predetermined value w.r.t. the vessel, the process being effected in two consecutive steps, heating the pierces and then treatment, the heating being effected under a pressure considerably lower than that in the second step, and under an electric tension considerably greater than that in the second step. The process, the apparatus, the reactor, the current input lead and the generator for the process are all independently claimed. A system can be set up in which the probability of sparking is suppressed to a lower level than in prior art while a higher energetic yield is obtd. while ensuring thermal conditions favourable to the stability of the discharge. The metal pieces treated can be quenched without contact with air immediately after treatment.

Title: Fuel economiser for gas fuel burners - supplies steam to flame in measured quantities
IPC: F23L7/00
Filed: 1975-03-17
Abstract: An economiser operates on gaseous fuels or on atomised liquid fuels furnished with a flame burner, by supplying steam to the system. Steam is defined as vapourised water as opposed to an atomised water supply. The steam is injected directly to the hottest point of the flame to ensure effective dissociation of the constituents. The steam jets are supplied in members around a burner, the steam jet making an angle of steam 25 deg. and 65 deg. with the centre line of the flame. The steam is controlled so as to remain proportional to the quantity of fuel or the load on the heater.

Title: Light-sensitive transducer - as exposure meter for photographic equipment
Inventor: ZINCHUK MICHAEL
IPC: H01L31/08
Filed: 1975-06-27
Abstract: Light-sensitive transducer of high radiation transparency, particularly for direct photographic illumination measurement in the path of the image rays, comprising a series of layers of high radiation transparency consisting of a substrate supporting a first electrically conducting layer or which separate photo-conducting layer is deposited and which in turn is covered by a separate second electrically conducting layer. The transducer is simple and cheap to produce and can provide an automatic exposure control system for a camera which responds directly to the same light proportions as picked up by the camera objective. It not only has a linear response photopotential, but its photo-conducting response sensitivity is approximately inversely proportional to the logarithm of the light intensity to which it is exposed.

Title: Surface hardening the bores of pipe elbows - using burner segments mounted on adjustable carriers so burner dia. can be varied
IPC: C21D9/08
Filed: 1975-09-16
Abstract: The parent patents describe a device for surface hardening by local heating to the hardening temp. o f the inner surface of pipe elbows, using gas-oxygen burners, with or without alteration of the core properties, and where either the elbow or the burner is moved to carry out the hardening operation. In the present invention, the burner consists of several segments, arranged in a circle on two semi-circular carrier arms of equal length; one end of each arm is mounted on a pivot on the middle burner segment which is located on an axial carrier, and the other ends of the arms can be moved towards or away each other so the burner segments can be adjusted to suit the dia. of the elbow being treated. The burner segments can be adjusted to cater for any out-of-roundness and/or variation in wall-thickness of the pipe elbow, to ensure uniform surface hardening.

Title: Vehicle fuel economising system - has parallel switches controlled by slider and brake and accelerator pedals for energising solenoid of clutch operating valve
IPC: B60K26/00
Filed: 1975-09-26
Abstract: The hydraulic slide valve (1) actuates the clutch of the engine transmission and is itself actuated by a solenoid. The solenoid is connected to a circuit (5) controlled by the engine ignition switch (7) and two switches (8,9) arranged in parallel. The switch (8) is actuated by a slider (10) so that the switch is closed only when the gear box is in neutral. The switch (9) is normally closed and is opened only when either the accelerator (11) or brake pedal (12) is operated. When the driver removes his foot from the accelerator pedal without applying the brake, the solenoid is energised and the clutch is consequently disengaged, so that the engine cannot act as a brake.

Title: Partially functional semiconductor memory cells - used by grouping byte orientated modules into sectors with no or simple corrigible defects (NL020377)
IPC: G11C29/00
Filed: 1976-08-18
Abstract: The amount of scrap can be considerably lessened and the costs can be reduced if even partially functioning semiconductor memory cells can be utilized in a working store. This has been achieved by arranging the individual byte-orientated modules, depending on the distribution of the double or multiple defects in the memory cells, optionally and flexibly in sectors. This is done in such a way that the defect correction device detects no defects or simple defects which can be corrected. A reconfiguration register in the memory module is used to store the control code for the grouping of the individual modules.

Title: Vibration damped mounting for tractor rollover frame - with elastic pads and limited play bolts to absorb running vibrations
IPC: B60R21/13
Filed: 1976-12-01
Abstract: The roll over frame of the tractor has mounting brackets for supporting the rear mudguards, with the lower ends of the mudguard walls coupled to the cab floor by elastic mountings.
