IPC: F16K31/08
Filed: 1957-09-20
Abstract: 862,506. Valves. MINISTER OF AVIATION, and ADAMS Ltd., L. Nov. 13, 1958 [Sept. 20, 1957], No. 29703/57. Class 135. A valve for an aircraft pressure breathing system has a gas inlet 2 and two outlets, one 3 permanently communicating with the inlet and the user's face mask, and the second 4, for inflating the user's clothing, being controlled by a valve 7 snapped open by a predetermined value of the fluid pressure on the inlet side and automatically closed by magnetic force, assisted if necessary by a light spring 24, when pressure in the clothing falls below that of the gas passing to the mask. Valve 7 is held closed by an armature 21, adjustable on the valve stem, being attracted by a permanent magnet 19. Above a certain altitude a predetermined high inlet pressure, after passing a barometric regulator and a pulsating flow-sensitive visual indicator, acts beneath a diaphragm 15 attached to the valve stem and overcomes ambient pressure acting above the diaphragm via a casing part and the magnetic attraction so that the valve snaps open. On fall of pressure in the inflatable clothing a differential pressure within the valve casing causes the valve to reseat. The valve 7 is provided with bleed holes 8.

Title: Apparatus for monitoring material thickness
IPC: G01B5/06
Filed: 1973-06-22
Abstract: 1383716 Detecting thickness variations J M ALPERIN 22 June 1973 29763/73 Heading G1M Continuous strip material, Fig. 1 moving along on a conveyer 46 passes beneath a thickness detector 41 or a cutter 48, any imperfect cut length being captured by a hinged door 57 operated by a signal transmitted from 41. In place of the cutter a dye marker may be utilized to indicate the detected points of thickness variation. The detector 41 comprises a vertically telescopic sprung leg 60, Fig. 2, to which is pivoted at 62 an L-shaped leg 61 integrally supporting an L-shaped arm 64 carrying at its upper end a cam 65 operating either micro-switch 101 or micro-switch 102 according to displacement of the arm 64 and the leg 61 which is held against the material by spring 85, any vertical displacement of roller 45 producing a lateral displacement of cam 65 to operate one of the switches. The detector 41 may be adjusted in several ways to detect any predetermined differential thickness or variation, and detect maximum and minimum thicknesses if a third micro-switch is fixed above 65. A solenoid 78 is actuated under normal conditions to swing an arm 77 and cause the legs to be locked against vertical movement in a sliding block holder 66, but pivoting movement of the leg 61 about the screw 62 due to thickness variation de-energizes the solenoid and allows the two legs to again move upwardly together and the height of the pivot screw 62 to re-adjust. Thus the combined operation of stationary leg 60 and movable leg 61 achieves the dual result of detecting thickness variations and adjusting to a new uniform thickness within the adjusted limits so that once a new thickness is detected to have existed throughout at least a predetermined length, the reference or datum thickness is adjusted so that thereafter no indication of thickness variation is given. An electric circuit Fig. 5 (not shown), controls the operation of the various devices including a counter. (For Figures see next page)

IPC: D06P5/10
Filed: 1949-11-22
Abstract: The fastness properties of dyeing or prints with direct dyestuffs which are water-soluble owing to the presence of sulphonic acid or carboxyl groups are improved by treatment with an aqueous solution containing a condensation product of an aldehyde with a nitrogen compound containing at least once the grouping <FORM:0673711/IV (c)/1> which condensation product has been produced in the presence of acid in an amount of 0.1-0.9 equivalent for 1 mol. of nitrogen compound.  Particularly suitable condensation products, which are advantageously employed in solutions of 0.05-0.4 per cent strength, are those of 1 mol. of dicyandiamide with 2-4 mols. of formaldehyde in the presence of 1/10 -\ba1/2 mol. of a lower fatty acid, preferably with 2-3 mols. of formaldehyde in the presence of 1/6 -\ba1/2 mol. of acetic acid.  Formic acid or inorganic acids (e.g. sulphuric or hydrochloric acid) dicyandiamidine, guanidine, acetoguanidine, biguanide, alkyl- and aryl-biguanides, and di- or other poly-biguanides, and acetaldehyde, may also be used.  The treatment, which may be carried out at room temperature or at elevated temperature, e.g. 70-75 DEG  C., is applicable to dyeings and prints on animal fibres (e.g. wool or silk) or especially cellulosic fibres (e.g. cotton, linen, or artificial silk or staple fibre of regenerated cellulose), including after-coppered dyeings and prints with azo dyestuffs from o-hydroxy- or o-carboxy-diazo compounds and coupling components coupled in a position vicinal to a hydroxy group.  Examples describe the treatment of dyeings on cotton with Brilliant Purpurine 10B, Chlorantine Red 8BN (Registered Trade Mark), or Direct Sky Blue green shade with various condensation products of dicyandiamide with formaldehyde in the presence of acetic acid and with a condensation product prepared similarly from a mixture of biguanide nitrate and guanidine nitrate obtained by heating dicyandiamide with ammonium nitrate, and the similar treatment of cotton dyed with Melantherine BH (Registered Trade Mark), the after-treated dyeing being subsequently discharge printed.

Title: Improvements relating to content addressed memories
Inventor: TOWELL ROGER PERCIVAL

Filed: 1964-07-29
Abstract: 1,111,051. Digital memory device. ELECTRIC & MUSICAL INDUSTRIES Ltd. 29 July, 1965 [29 July, 1964]. No. 30074/64. Heading G4C. A content addressed memory, e.g. a matrix of transfluxors, on reading produces from each storage location individual successions of pulses, the numbers represent an identification tag, means being provided for comparing the said tag with a particular tag to be selected. As shown, data can be entered into rows W1-WP of the memory and can be read out on lines S1-SP by means of reading lines RO-RN. An interrogating frequency 2F is applied to a set of flip-flops 1-(N+1) connected in series such that the frequency of pulses leaving each flip-flop is half the frequency applied thereto. One output of each flip-flop is applied to the read line and if " 1 " is stored in a transfluxor threaded by the line then a number of pulses proportional to the numerical value of the particular digit appears on the appropriate line S1- SP. The pulses are arranged such that there is no overlap of pulses from each element on a read-out line so that a series of pulses proportional to the number stored appears on each line. To identify a particular number the number required is entered into register 2<SP>o</SP>-2<SP>N</SP> so that gates 2 are opened and the series of pulses are passed, for each bit position storing a " 1." The series of pulses on line IS passes via a delay D1 to a counter where it is compared with the series on lines S1-SP, each of the lines having a separate counter. The input to each counter comprises a flip-flop, two delays and two AND gates connected as shown. If the pulses on lines IS and S1 are identical then, due to delay D1, the pulse on S1 sets FF1, which previously enabled gate B 1.1. Due to delay D3.1 gate B2.1 is inhibited for the duration of the first pulse and so the counter is unaltered. When the first pulse from IS enters FF1 is reset but because of the delay gate B1.1 is not enabled in time to pass the pulse so again the counter is unaltered. This repeats for all the pulse chain. If the two pulse chains do not coincide then one of the lines will have more pulses than the other, the increase being representative of the different bit position. Thus if information identified by tags having a number within a particular range is required, then the counter can be arranged to select these e.g. by being connected to a digital to analogue converter the analogue signal being applied to a pre-set threshold device. Alternatively an integrating circuit may be used instead of the counter. FF1 may be replaced by an AND gate and gates B1.1 and B2.1 by inhibit gates receiving pulses from the AND gate. The delays D1, D2.1, D3.1 would then be unnecessary. It is stated that other radices than 2 may be used.
