Abstract: 1,089,854. Mounting microfilm. ATLANTIC MICROFILM CORPORATION. March 1, 1965 [March 2, 1964], No. 8625/65. Heading G2C. A roll of developed microfilm has a narrow strip of adhesive material applied along each edge of one face, so that when the roll is subsequently cut up into separate lengths, these are adhered side by side to a transparent supporting sheet by being pressed on to it. Fig. 1 shows a machine for carrying out this process. 16 mm microfilm F is wound off a reel 16, guided under a flanged roller 18 (see also Fig. 3, not shown) and a second guide roller 20 (see also Fig. 5, not shown), then between pressure rollers 30, 32 to a take-up reel 50. Two narrow (about 1/16 inch) strips of tape T which is adhesive on both sides in wound off a spool 45, the tapes having a temporary protective covering on one face so that the turns do not stick together. The tapes are guided by a grooved roller 46 (see also Fig. 4, not shown) to roller 20, where they come into contact with the underside of film F. The assembly of tapes and film now passes between rollers 30, 32, upper roller 32 being spring-biased against lower roller 30. Roller 32 is formed with annular collars 32', so that pressure is applied only at the edges of the film, where the tape strips are. The assembled roll of film on reel 50 may then be conveniently cut-up into, say, 5" lengths, and the protective covering stripped off the adhesive tapes. The film length is then placed, adhesive side down, on the support sheet, and pressed into adherence thereto.

Title: Receivers for pulse communication systems
IPC: H03K9/04
Filed: 1944-05-09
Abstract: 593,731. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. May 9, 1944, No. 8847. Convention date, July 3, 1942. [Class 40 (v)] In a time-modulated pulse signalling system of the kind described in Specification 592,414, in which signals are conveyed by variation of the time interval between pairs of short pulses, the received pulses are passed through a shaping circuit to a filter designed to pass a narrow band of frequencies centred around an harmonic of the pulse pair periodicity. The narrow received pulses are shaped into wider pulses which are started by either the leading or trailing edge of the received pulse and last for a constant period depending on the shaping circuit. The shaping circuit comprised a multivibrator valve pair V1, V2 with a common cathode resistance 30 and with the anode of valve V1 coupled to the grid of valve V2 through a condenser 33. The normal condition is such that valve V1 is blocked and valve V2 is passing current due to the positive bias from the source B. When the leading edge of a positive pulse is applied to the grid of the valve V1 that valve conducts, its anode voltage falls and the grid of valve V2 falls in voltage sufficiently to block the valve V2, which remains blocked for a period dependent on the time constant of condenser 33 and resistance 34. The shaped impulses are applied to a filter which passes a band of frequencies around an harmonic of the pulse - pair periodicity. The filter output is thus amplitudemodulated and may bo passed to phones &c. through an amplitude detector. A separate message may be transmitted as an amplitude modulation of the pulses.

Abstract: 474,155. Rectifying alternating current. ENGLISH ELECTRIC CO., Ltd., BALL, R. D., and CALVERLEY, J. E. March 26, 1936, No. 9011. [Class 38 (ii)] In, a grid-regulated arc rectifier the output voltage is regulated in accordance with some other variable such as load current only when the variable lies to one side of a selected valve. In one arrangement a D.C. voltage varying with load current and derived from a shunt on the D.C. side or from a current transformer 9 on the A.C. side and rectfier 10 is opposed to a voltage 6 in a circuit including a field winding 5c of a generator supplying grid potential or a synchronous motor 5 driving a generator or distributer 4 supplying grid potentials. A rectifier 8 is included in the circuit of the winding 5c so that only when the load current exceeds, or alternatively falls below, a selected value is voltage regulation effected by phase shift of the grid potentials due to excitation of the winding 5c. The arrangement may be made to effect either compounding or decompounding, and in a modification an additional field winding may be provided on the motor or generator and continuously excited by a current proportional to the rectifier load current so as to modify the regulation effected by the winding 5c. The rectifier 8 may be of any type, or may be replaced by a relay polarized or otherwise excited so as to close only when the resultant voltage in the circuit of the winding 5c is of one polarity. The invention may also be applied to arrangements in which the rotary apparatus 4, 5 for supplying the grid potentials is replaced by static apparatus.
