Title: Improvements in or relating to pulse generating apparatus
Inventor: BRIGGS PETER GEORGE
IPC: H03K3/45
Filed: 1957-07-19
Abstract: 833,376. Circuits employing bi-stable magnetic elements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. May 19, 1958 [July 19, 1957], No. 22928/57. Class 40 (9). In a circuit utilizing magnetic cores with rectangular hysteresis loops, the Switching current applied to an arrangement of cores 1, 7 for the purpose of applying a reading pulse to a selected row winding of a magnetic storage matrix 6 is limited in amplitude by reversing the saturation remanent state of a further core 9. This current amplitude limitation is stated to be necessary to avoid overcoming an inhibiting bias applied to a winding 4 on the core 1, 7 associated with an unselected row. In operation, the switching current pulse is applied to cores 1, 7 and 9 by way of a triode or pentode valve 8. The pulse is of such amplitude and duration that it terminates before core 9 completely reverses its magnetic state, and a writing pulse is established in the output winding 5 of an unhibited core 1, 7. A valve 14 is then made conductive so that core 9 is reset to its initial magnetic state. A valve 15 controls the application of a switching pulse to windings 3 on cores 1 and 7 so that writing pulses are induced in windings 5, the recording of information being effected in the usual manner by coincidence of currents in row and column windings (not shown). The amplitude of each row writing pulse is restricted by limiting the potential across windings 3, and a limiting circuit comprising a rectifier 18 biased by an adjustable low-impedance source comprising a cathode follower 19 and an adjustable potentiometer 20 is provided for this purpose

Title: Improvements in or relating to suspension systems for motor vehicles
IPC: F16F9/02
Filed: 1956-07-25
Abstract: 812,395. Pneumatic shock absorbers. DEVILLERS, R. July 25,1956, No. 23000/56. Class 108(3) A motor vehicle suspension system includes a pneumatic telescopic suspension and shock damping device which comprises an elastic suspension member 38 precompressed to a value greater than the minimum static load of the vehicle, in series with a suspension and damping system comprising at least two separate damping stages in which damping is effected by throttling the passage of a gas which is under pressure. As shown, the spring 38 comprises two concentrically disposed coil springs 37, 38, acting between an abutment rigid with a piston rod 25, and an abutment 13, rigid with the lower end of a tubular member 11 which is slidable with respect to a rod 10 rigid with a main cylinder 1 of the device. The upper abutment of the springs 37, 38, is rigid with a cylinder 40, which by virtue of a seal ring 39 and a spacer ring 41, functions as a piston within the cylinder 42. Damping results from restricted air flow, resulting from relative movement between the sleeve 11 and the rod 10, and between the abutment 13 and the wall of the cylinder 40. There is a one-way valve at the upper end of the sleeve 11. Alternatively, the sleeve 11 may be closed at its top and the one-way valve may be formed in the plug 48 closing the upper end of the rod 10. The latter may be solid however, and may be of conical form so as to result in a damping action which progressively varies. The springs 37, 38, may be replaced by the action of pneumatic pressure which may be charged via a valve 20 in the piston rod 25. In this case, a seal ring is provided between the foot of the sleeve 11 and the inner wall of the cylinder 40. The sealing ring may however be replaced by machined surfaces if the air connection 20 is coupled to a source of external air pressure. The spacer'ring 41 may be replaced by a packing ring. A one-way valve may be mounted at the base of the cylinder 40 in order to promote the transfer of air between the abutment 13 and the annular head 14 at the base of the cylinder 2. The plug 48 in the rod 10 may be of rubber. Sound deadening is promoted by the provision of suitable material 45 for the mounting of the rod 10, and a disc 49 resting on the head 14 of the cylinder 2. The pressure in the main cylinder 42 may also be maintained by a connection via a reducing valve 9 to a source of external pressure. A valve may be provided in the upper head 42a of the cylinder 42 to enable the space above the seal ring 39 to be charged with a counter-acting pneumatic pressure. This may be effected by allowing this space to be open to atmospheric-pressure when the shock absorber is fully compressed.

Title: Manufacture of azo dyes on the fibre
IPC: C09B29/20
Filed: 1934-08-15
Abstract: Azo dyes are made on the fibre by coupling the diazo compound of an amine of the formula <FORM:0442873/IV/1> (in which Z = a furyl or substituted furyl group, X = H or OR and R = alkyl) with an arylide of 2 : 3-oxynaphthoic acid, both components being free from solubilizing groups such as SO3H or COOH.  The diazo compound may be applied in the form of a diazoimino compound, e.g. in a printing paste, the colour being developed by acid treatment.  Violet and blue shades are obtained. In examples, the following dyes are produced on cotton: (1) 2-furoylamino-5-aminoanisole --> the b -naphthylamide; (2) 4 - furoylamino - 2 : 5 - diethoxyaniline --> the o-toluidide; (3) chlorofuroyl - 4 - amino - 2 : 5-dimethoxyaniline --> the o-toluidide; (4) a paste containing the o-toluidide and the diazoimino compound from diazotized 4-furoylamino-2 : 5-diethoxyaniline and piperidine-a -carboxylic acid is printed on cotton and developed with steam containing acetic acid. Specifications 303,838 and 313,865, [both in Class 15 (ii)], are referred to.  Chlorofuroyl-4-amino - 2 : 5 - dimethoxyaniline is made by refluxing furoic acid with sulphuryl chloride, condensing the chloro-furoyl chloride thus obtained with 4-nitro-2 : 5-dimethoxyaniline in presence of benzene and potassium carbonate and the product reduced by hydrogenation at 100 DEG  C. in methyl alcohol using a reduced nickel catalyst.  The Specification as open to inspection under Sect. 91 comprises the production of azo dyes in substance or on the fibre by coupling the diazo compound of an amine of the formula <FORM:0442873/IV/2> (Z and R as above) with an arylide of 2 : 3-oxynaphthoic acid or an acyl-acetyl derivative of an aromatic mono- or diamine.
