Title: Ketones from Grignard reagents and nitriles contg. alpha hydrogen atom - in presence of lithium or quaternary ammonium perchlorate
Inventor: CHASTRETTE MAURICE
IPC: C07C45/00
Filed: 1974-11-29
Abstract: Ketones are prepd. by adding an organic nitrile of formula (R1)(R2)CH-CN or CN-(CH2)n-CN to a soln. of an organo-Mg cpd. of formula RMgX together with lithium perchlorate or a quat. ammonium salt of formula +N(R1)4ClO4- where R' is alkyl, R is aliphatic provided the C atom bearing Mg is not quaternary nor substd. by an aromatic ring and if R is 2C the gp. is satd. and if R is 3C or above the first 3C atoms are satd., X is Cl, Br or I, R1 and R2 independently are H, straight chain aliphatic or aromatic or R1 and R2 form an alicyclic or heterocyclic ring and n is at least 3; after reaction the product is hydrolysed with an aq. acid phase followed by extraction of the ketone. Previously the reaction has found only limited application because of the low yields obtd. when an alpha H atom is present. As a result of the presence of the salt the yield is increased by >=50%.

Title: Transistorised differential amplifier - has two transistors to whose bases input signals are applied
IPC: H03F1/08
Filed: 1974-12-12
Abstract: These two transistors amplify the difference between the two input signals. An active load is in series with the second transistor collector which delivers the output signal. The active load consists of a bipolar transistor amplifier so connected, that the second transistor collector current flows through it. A frequency stabilising capacitor is inserted between the load transistor collector and base. A second load transistor has its base terminal connected through a resistor to the collector terminal, and through another resistor with the base terminal of the first load transistor.

Title: Self-lifting shutters for pouring concrete - has pole anchored below to raise panels hand over hand
Inventor: BLONDE GUY
IPC: E04G11/28
Filed: 1975-01-27
Abstract: The self-lifting shuttering allows concrete to be poured in continuous layers and consists of units pushed together. Each unit comprises a shutter panel(1) and a control mechanism(2) which is temporarily anchored in the layer below already cast. This mechanism has a vertical pole(7), positioned towards the outside in the middle part of the shutter-panel some distance from the wall(8) being cast. This pole acts as a runner for a cursor(13) attached to the panel. The cursor is in contact with the pole and also by being adjustably linked to uprights supporting the panel, controls both the front and back slope of the panel in relation to the wall, as well as its bending in both directions. The pole is adjustably anchored to the wall so that it can be moved nearer to or further from it.

Title: Fluid developer stage for photocopier - uses overlapping array of jets and drainage ducts for even application of fluid
IPC: G03G15/10
Filed: 1975-03-12
Abstract: The developing station of the photocopier has a special container to hold the fluid developer whose upper end is covered with an array of tubes.

Title: Hydraulically controlled head lamp alignment - with automatic master cylinder refilling from reservoir and with safety stops on slave cylinders
IPC: B60Q1/064
Filed: 1975-06-04
Abstract: The two headlamps are aligned using two hydraulic cylinders which are connected to a common master cylinder (16, 17) which has two pistons (18, 19) operated by a single adjustment screw (35). The master cylinder is connected to a reservoir which ensures that any fluid loss is compensated for. The two alignment cylinders are fitted with stops which limit the maximum delfection of the headlamps as a safety measure. The system not only compensates for fluid loss but also for variations in the volume of the flexible hydraulic lines due to age etc. Valves (30, 31) in the adjustment pistons allow entry of more fluid when the screw is backed off past the stops on the slave cylinders.

Title: Building tile for walls or floors - has decorative design on visible surface, with grooves and hollowed areas interconnecting with those of adjacent tiles
IPC: E04F15/08
Filed: 1975-07-25
Abstract: The building tile for covering wall or ground surfaces has four sides (2-5) but may have other shapes. The tile may be of stone, moulded or injection-moulded material, such as concrete, ceramic, glass and any other suitable material. The visible surface (6) of the tile bears a design which is formed partly of an area which is lower than the flat surface (6) and is positioned so that it connects with similar areas on adjacent tiles (1a-1h). The design can incorporate a number of grooves (7-9) which cut the circumference of the tile, for instance on two consecutive sides (2, 3), dividing each of these sides into four equal lengths. The arrangement of the grooves on the tiles enables the tiles to be placed in two different relative positions, while still preserving continuity between the grooves from one tile to the next.

Patent FR-2301044-A1 (FR)
IPC: G04G5/00
Filed: 1976-02-12
Abstract: A one button-switch time display set and adjustment apparatus for an electronic timepiece having a digital electro-optic display. The (time) information being displayed is set or adjusted by depressing and holding depressed the buttonswitch which causes the display indicia, i.e. digit (s) and other time display intervals, each to flash or flicker separately in a predetermined order. If the button-switch is released while the segment to be adjusted is being interrogated, indicated by the flickering or flashing of that indicia, the interrogation operation or sequence is interrupted and that indicia continues to flicker. Depressing and holding depressed the button-switch again, for a predetermined time, causes updating of the interrogated indicia at a 1 HZ rate. Releasing the button-switch stops the updating of the selected display indicia and causes the timepiece to return to the normal running mode or operation.

Title: Bimetallic catalyst including silver - formed by displacing second metal from solution by first metal
IPC: B01J23/48
Filed: 1976-02-16
Abstract: A bimetallic catalyst is produced by contacting silver, either as a powder of surface area 0.01-100 m2/g or on a refractory metal oxide support, with an aqueous solution of a salt of gold, iridium or platinum. In a preferred embodiment a solution of chloro auric acid contains 1 x 10-5 to 1 x 10-3 g. of gold per 1 m2 of available silver surface. As the catalyst is formed only on the surface of the silver the image of the expensive second metal is minimised. Furthermore the process provided control of surface composition and thus of catalytic activity.
