Title: Mechanism for selecting index cards
IPC: G06K21/02
Filed: 1971-12-15
Abstract: 1356869 Selecting cards from a stack DATAGRAPH AG 15 Dec 1971 [23 Dec 1970] 58343/71 Heading G4M  A selector for cards secured at a top edge to a connector 27 having removable coding tags 31, 32 has individually movable selector bars 21 in slots in a cross-bar 16 and a reciprocable engager bar 68 withdrawing selected cards. The cards are supported on L-shaped bars 11, 12 and held by reciprocable bars 22, 23. To select a card one or more of bars 21 are lowered and bars 22, 23 are raised. Bar 68 is moved to engage in slots 34 in one edge of the cards and is withdrawn. The required cards have a tag missing adjacent the lowered selector bar or bars and are moved to the left by engager bar 68. To aid removal of the cards bar 69 is moved at an angle to the cards and is received in a slot in the non-selected cards and aids ejection of the selected cards. When the cards have been withdrawn such that upstanding portion 58 of the connector engages L- shaped bar 12 then bar 68 which may be tilted is released from the slot and bars 22, 23 are lowered to depress the selected cards until a tab 63 on belt 64 engages a hole 62 in the card and fully withdraws the card. Bar 68 is tapered to allow easy entry into the slot and the lips 42, 43 of the connector may deform.

Abstract: 1,187,320. Biochemical isolation of i-menthol. TAKASAGO PERFUMERY CO. Ltd. 11 Dec., 1968, No. 58850/68. Heading C2C. A process for the biochemical isolation of lmethol comprises asymmetrically hydrolysing an organic carboxylic ester of dl-menthol or a mixture of organic carboxylic esters of dlmenthol isomers containing dl-menthol, wherein the organic carboxylic acid utilized to form said ester is of the formula R.COOH wherein R represents a hydrogen atom or an alkyl C 1-21  or alkenyl C 2-21  radical, said asymmetric hydrolysis being performed by carboxylic ester hydrolase, which has been produced by the action of microorganisms belonging to the genera Penicillium, Gliocladium, Trichoderma, Geotrichum, Aspergillus, Pullularia, Fusarium, Absidia, Cunning- hamella, Rhizopus, Actinomucor, Chlamydomucor, Mucor, Gibberella, Streptomyces and Bacillus; and separating optically active lmenthol from the enzyme reaction mixture. When esters of dl-menthol isomers are used the hydrolysis results in the formation of l-menthol and l-isomenthol only and l-menthol may then be obtained by rectification, derivative formation, recrystallization or chromatography.

Patent GB-1224330-A (GB)
Title: Load-responsive pressure-reducing or limiting valve for hydraulic brakes
Inventor: CERVENKA JIRI
IPC: B60T8/18
Filed: 1968-12-20
Abstract: 1,224,330. Load-responsive pressure-varying brake valves. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. 20 Dec., 1968 [21 Dec., 1967], No. 60709/68. Heading F2F. In a load-responsive pressure-reducing or -limiting valve for hydraulic brakes comprising a differential piston arranged in a differential bore in a valve body, there is provided, in the valve body, an auxiliary differential piston in a differential bore; the smaller end of the auxliary bore communicates with the larger end of the main bore, and vice versa, and the smaller end of the main bore also communicates with the brake cylinder. As shown, a differential regulating piston 2 is located in a differential bore in a body 1, clearances being provided so that when piston 2 is in its upper position a chamber A above it is in communication with a smaller chamber B below it. Chamber A is connected by duct 8 with small chamber C on the left of an auxiliary differential piston 7, while chamber B is connected by duct 6 with large chamber D on the right of the auxiliary piston 7. Chamber B is also connected by duct 5 with the wheel cylinder (e.g. of the rear axle). A force P directly proportional to the resultant axle load acts on the piston 2. The master cylinder output (not shown) is connected to an apertured plug 3. In operation, when the brake pedal is depressed, hydraulic fluid at pressure p1 is delivered through apertured plug 3 to chamber A, and hence to chamber C. The piston 2 is in an upper position at this stage, so the fluid is conveyed to chamber B and connected chamber D and to the wheel cylinder, all at pressure p1. When the pressure multiplied by the net surface area of piston 2 exceeds the load regulated force P, piston 2 moved downwards, and by its packing 4 shuts off the connection between chambers A and B. The moment of closure marks the onset of pressure regulation for the system. Until the closure, the pressure in the wheel cylinder is equal to the pressure at the apertured plug 3. As the driver increases the mastercylinder pressure after the closure, the pressure medium flows only along duct 8 into chamber C, where it acts on the smaller end of auxiliary piston 7; the original pressure at which the main piston 2 closed still acts on the larger end of auxiliary piston 7. A spring 11 urges piston 7 towards the left. When the total fluid force on the left of piston 7 exceeds the combined fluid and spring force on the right of it, the piston moves to the right until equilibrium is established. The resulting volume reduction in the region between piston 7 and the wheel cylinder effects an increase in the pressure in the latter. The magnitude of this pressure increase may be varied by varying the relative diameters of the parts of the auxiliary piston 7.

Title: Process for Producing Fuel Gas and Fluidised Bed Reactor for Carrying out the Process
Inventor: LINNEBORN H
IPC: C10J3/56
Filed: 1978-09-27
Abstract: Fine-grained to coarse-grained or fibrous fuels of organic origin are processed with omnidirectional relative movements of the fuel particles and gasifying agent in a fluidised bed under such conditions that the fuel gas product is entirely, or substantially, free from contents of heavy hydrocarbon, hydrocarbon compounds, substances which form tarlike condensates when cooled below their dew point temperature, as well as phenols and phenol compounds. These conditions can be adjusted such that the height of the fluidised bed is maintained below an upper limit at which the fluidised bed is torn open more than locally, and such that the height of the fluidised bed is maintained above a lower limit at which the fuel gas still contains the abovementioned substances.
Patent GB-2036476-A (GB)
Title: Improvements in or Relating to Earth Leakage Circuit Breakers
IPC: H02H3/33
Filed: 1978-12-07
Abstract: A device for increasing the sensitivity of an earth leakage circuit breaker comprising a resistor R1 connected in the earth lead to detect earth leakage current. The potential difference which occurs across the resistor in the event of an earth leakage is amplified by an amplifier A and used to close a switch 6. When switch 6 is closed the live lead is connected through a resistor R2 to the earth lead, thus causing current to flow from the live lead into the earth lead and hence through the coil 2 of the circuit breaker to cause positive operation of the circuit breaker. Resistor R1 may be replaced by the coil 2 or by a current transformer embracing the live and neutral leads. <IMAGE>
