Title: Improvements relating to compensatory spring suspensions in motor vehicles
IPC: B60G11/27
Filed: 1959-09-16
Abstract: 857,039. Preventing lateral canting. DAIMLER-BENZ A.G. Sept. 16, 1959 [Sept. 26, 1958], No. 31568/59. Class 108(2). A compensating pneumatic suspension for motor vehicles comprises compensating pneumatic springs 7 which act as dampers for pneumatic main springs 5 during straight-ahead travel, having a control device 8 adapted to supply compressed air to the compensating springs on the inside of a curve and to connect those on the outside to atmosphere. The control device 8 consists of a bore 20 containing a control slide valve 22 with end piston parts 21 abutting against disc valves 23 which are disposed in valve chambers 23a and normally close the bore 20. Each chamber 23a is connected to a compensating spring by pipes 9, 10, and also to atmosphere through a valve 25 and port 28. The valve 25 has a small central aperture which lies opposite a small disc valve 24. A compressed air supply pipe 11 and ducts 30 lead from a reservoir chamber to the bore 20. When the vehicle is set for straight-ahead travel, the control valve device is as shown in Fig. 3. Springing movements cause air to be drawn in from, and expelled out to the atmosphere with damping action through the port 28. When the vehicle goes round a curve, e.g. to the left, a pendulum 26 swings sideways in the direction of the arrow due to the centrifugal force, moving the valve 22 to the right. The right hand piston part 21 opens valve 23 and closes valve 24, and on further deflection uncovers the supply duct 30 so that compressed air flows to the compensating spring 7 on the inside of the curve. The expansion of the spring 7 causes the vehicle chassis to move towards the axle and the centre of gravity of the vehicle is lowered. When the vehicle has rounded the curve the pendulum 26 swings back to its original position and the control device resumes its position shown in Fig. 3. The pneumatic springs 5 may be replaced by helical springs.
Patent GB-1019571-A (GB)
Title: Preparation of 2-dehydroemetine derivatives
Inventor: RITCHIE ALEXANDER CRAWFORD
IPC: A61K31/47
Filed: 1961-09-01
Abstract: The invention comprises compounds of the formula <FORM:1019571/C2/1> and their acid addition salts, wherein R1 is an aliphatic, araliphatic or aromatic hydrocarbon group, R1 is an aliphatic, araliphatic or aromatic hydrocarbon group which may have hydroxy or acyloxy substituents and R3 is hydrogen or an acyl group, and wherein the benzene rings optionally bear one or more aliphatic, araliphatic or aromatic hydrocarbon or ether (including methylenedioxy) groups as substituents; and the process for the production of the corresponding derivatives having a group R1.CH2- in place of R1.CH(OR3)- in the 3-position by reducing compounds of the above formula wherein R3 is an acyl group by means of a metal/ammonia or metal/primary amine reducing system, e.g. lithium or calcium in liquid ammonia.  The compounds of Formula II are prepared by reducing a corresponding ketone (having a group R1CO in the 3-position and in which R1 may also bear oxo substituents) with a reagent serving to reduce an oxo group to a hydroxyl group, e.g. a metal hydride reducing agent such as an alkali or alkaline earth metal borohydride or aluminium hydride, and acylating the product, e.g. by reaction with an acid anhydride such as acetic anhydride.  When the starting material contains a group R2CO.CH2-CH2- as the substituent R1 in the 21-position (R2 being an aliphatic or araliphatic hydrocarbon group, e.g. CH3), reduction converts this to the corresponding 3-hydroxy radical and, on esterification to the 3-acyloxy radical, which remain unreduced by the subsequent metal/ammonia or metal/primary amine reaction. The resulting product containing a 21-(3-hydroxyalkyl)-side chain may be oxidized to the corresponding 3-oxo-alkyl derivative and the side chain may then be removed by oxidation and treatment with hydrazine or a base, or in one step by Oppenhauer oxidation with an alkali-metal alkoxide and a ketone.  Preferably the ring system contains methoxy substituents in the 61, 71, 9 and 10 positions giving products of the emetine series.  In examples 3-acetyl - 1,4,6,7 - tetrahydro - 9,10 - dimethoxy - 2 - [11,21,31,41 - tetrahydro - 61,71 - dimethoxy - 21 - (311 - oxobutyl isoquinol - 11 - yl] - methyl - 11b[H]-benzo-[a]-quinolizine is reduced with sodium borohydride to give the corresponding 3 - a  - hydroxyethyl - 21 - (311 - hydroxybutyl) - compound, treated with acetic anhydride to form the diacetate, reduced with lithium aluminium hydride in liquid ammonia to give N-(3-hydroxybutyl) dehydroemetine and treated with potassium t.-butoxide and benzophenone to give dehydroemetine (hydrogen chloride); similarly the reduction is also effected with sodium and calcium in liquid ammonia in place of lithium.

[Also in Division C7] A film resistor is formed by applying metal layers to an insulating substrate 3, each layer being oxidized separately and substantially completely. The metal may be nickel chrome alloy (possibly with iron) or chromium, tantalum or molybdenum. It may be applied by sputtering or by vapour deposition from a source 5 arranged in a box shaped space in a bell jar 1 exhausted through a tube 8. The substrate 3 and a monitor substrate 3a are heated by an infra-red source 7 to 350 C., heating current is passed through source 5, the rotor carrying substrates 3 and 3a (glass) is set in motion and shutter 4 is moved so that metal layers are formed on 3 and 3a. When monitor 3a shows a resistance of 200 K# per square, shutter 4 is moved back to stop vapour deposition. Air is then admitted at 6 to a pressure of 6 x 10<SP>-4</SP> Torr and the metal layers are oxidized until their resistances cease to increase. Further layers (e.g. two) are then applied in the same way. The layers may be partly oxidized during deposition. The resistors may be formed on an oxide layer on a semiconductor as part of an integrated circuit or on an insulating substrate also carrying thin film resistors and capacitors.

Filed: 1958-10-15
Abstract: 838,144. Detecting radioactivity. BARCROSS Ltd. Oct. 15, 1958 [Oct. 15, 1957], No. 32210/57. Class 40 (3). A rise in radioactivity in dust particles in a gas is detected by passing the gas through a filter at a constant rate and detecting the radiation from particles trapped in the filter. Under steady conditions the increase in radiation due to new particles being trapped is balanced by the decrease due to natural decay of activity from the old particles, and the detector output is constant. A rise in output therefore denotes an increased number of radioactive particles being trapped. In the Figure a constant-speed displacement pump 13 sucks air into a chamber 15 via a filter paper 16. A Geiger counter 20 detects the beta radiation from the paper, and a further counter 23 measures the background radiation. Signals from the two counters are combined in a rate meter 22 and their difference operates a recording chart and audible alarm in a unit 25. A further warning is given if the pressure in the chamber 15 rises due to rupture of the filter paper. The Geiger counter can be replaced or supplemented by a scintillation counter and photomultiplier for detecting alpha radiation.
