Title: Improvements in devices for fastening the edges of flexible material
IPC: A44B19/38
Filed: 1931-08-10
Abstract: 383,319. Sliding - clasp fasteners. FREY, S., 11, Am Park, Schoneberg, Berlin. Aug. 10, 1931, No. 22583. Convention date, Aug. 12, 1930. [Class 44.] To minimize friction in a sliding-clasp fastener, each member 1 on one stringer has a projection on one face and is smooth on the other, and each member 2 on the other stringer has a recess in one face, and is smooth on the other face, so that each member interlocks with only one adjacent member. This construction allows a slider with more acute angle than usual to be employed. The internal wedge member p in the slider is formed by stamping external V-recesses in the upper and lower plates. The slider may have an ornament which hides its identitv as a slider when applied to a dress &c. The stringers are separable, a split pin 8, Fig. 5, or spring hook 16, Fig. 10, on a terminal member 11 on one stringer engaging a countersunk or shouldered aperture in a terminal member on the other stringer. These terminal members have extended rigid plates 6, 7 with finger depressions V to facilitate handling in separating and assembling the stringers. To aid in guiding the stringers to correct position a pointed member 5 on one stringer engages under a shoulder on a member 3 on the other stringer, member 3 having a projection r which supports the adjacent fastener member 1.

Title: Improvements relating to speed-responsive devices
IPC: G01P3/20
Filed: 1938-03-30
Abstract: 504,270. Revolving radial - cylinder pumps ; speedometers ; servomotor - control systems. WELLS, R. G., EVANS, A. F., and HIGH-PRESSURE AIRSCREWS, Ltd. March 30, 1938, No. 22779/37. [Class 102 (i)] [Also in Groups XIX and XXIX] Radial cylinders 34 are carried by a casing 26 rotated by a pinion 13 about fixed eccentrics 18. Pistons 33 are secured to cross-heads 30 within which are slidably mounted members 29 connected by rods to the eccentrics IS. Liquid is drawn from the casing 26 through suction valves 36 and delivered through valves 43, the pipe 51, to the cylinder 53 having a piston 54 loaded by the spring 59 and weight 65, and connected to the rod 69. When the pressure in the system rises, until the centrifugal force acting on the pistons is unable to overcome the liquid pressure, then the pistons take up a position so that the port 57 is uncovered and the member 29 moves idly in the cross-head 30. If the speed increases, the pistons resume pumping, but if it decreases, the piston is moved back until a groove 66 connects the ports 67, 68 to relieve the pressure. The pressure is thus proportional to the speed and the position of the rod 69 may be used to indicate speed, or the apparatus may be used as a governing device. The spring- loaded piston 70 is connected to the rod 69 and acts as an emergency device to move the rod 69 in case of undue leakage.

Title: Waveform generator, particularly for television
IPC: H03B23/00
Filed: 1948-08-31
Abstract: 687,712. Television. HOLLAND, E. O., SMITH, J. B., and PYE, Ltd. Aug. 26, 1949 [Aug. 31, 1948]. No. 22895/48. Class 40 (iii). In an arrangement for generating line and frame synchronizing signals, a train of master pulses for controlling the production of line signals is fed to a divider in the form of a plurality of series-connected binary electronic counting devices and the output pulses from the divider are used to control the frame-signal generator. The divider 3 in the embodiment described comprises nine binary counting devices with pulses fed back to the first, second, fourth, sixth and seventh units so that the count is advanced by 107 and the divisionfactor is 405. A trigger circuit 4 comprises a resistance - coupled multivibrator circuit arranged for asymmetric operation, master pulses from generator 1 being fed directly (in negative form) to the anode of one valve and the pulses from divider 3 (also negatively) to the anode of the other valve. With this arrangement the multivibrator is held in one condition by the master pulses, is changed to the other condition by a divider pulse and is then changed back to the first condition by the next master pulse following the divider pulse. This last change-over produces an output pulse from the second valve and the trailing edge of this pulse triggers the frame generator 5. The triggering of generator 5 is thus directly related to the timing of the master pulses and is independent of any delay occurring in divider 3. This feature forms the subject-matter of a divided Specification 687,769. The duration of the frame pulse is controlled by an arrangement comprising a gating circuit 6 which is opened by the leading edge of the frame pulse to allow master pulses to pass through a further divider 7 with a divisionfactor of eight, the output pulse from this divider being differentiated at 8 and fed to generator 5 to terminate the frame pulse. The dividers 3, 7 and the trigger circuit 4 may all use circuits of the kind described in Specification 654,731, [Group XL (c)]. Specification 687,713, also is referred to.

Title: Improved system of blind approach and landing for aircraft
IPC: H03G3/20
Filed: 1949-09-07
Abstract: 675,110. Radio navigation; automatic gain control. PYE, Ltd., and WEIGHTON, D. Aug. 30, 1950 [Sept. 7, 1949], No. 23143/49. Classes 40 (v) and 40 (vii). In a system for guiding aircraft during landing the aircraft comprises a receiver which co-operates with a ground transmitter and includes automatic-gain-control circuits, the action of which is interrupted during landing by the reception of the signal radiated from a marker beacon, the gain of the receiver thereafter being maintained at the value it had at the moment of interruption. In the arrangement illustrated in Fig. 1, a transmitter 3, which may also be the transmitter radiating overlapping-beam signals for guidance in azimuth and comprises an aerial fixed at a height of not more than two wavelengths above the ground, is located beyond the end of the runway and transmits horizontally polarized signals having lines of constant field strength 6, 7, 8. An aircraft approaches the airfield at a constant height as determined by a barometric altimeter until it passes over marker beacon 5 when a signal is received which interrupts the action of the A.G.C. circuits and maintains the gain of the receiver, which may be the receiver for receiving the localizer signals, at the value it had when the A.G.C. was interrupted. Simultaneously a condenser which is charged to a potential corresponding to the second detector output at the instant that the A.G.C. was interrupted commences to discharge and the potential across the condenser is balanced against the output from the receiver by means, as described for example in Specification 568,566, [Group XXXVI], so that by maintaining the two potentials equal at all times the aircraft follows a landing-path crossing the lines 6, 7, 8 as indicated. Alternatively the output from the second detector 13, Fig. 3, may be made to decrease at such a rate that the discharge of condenser 16 balances the current flowing through resistor 18, and meter 17 consequently gives a null indication. In the arrangement illustrated in Fig. 2, reception of a signal from the marker beacon 9 interrupts the A.G.C., whereafter the aircraft follows a constant-field-strength line by comparison of the receiver output with a constant reference potential. Reception of a signal by a second marker beacon 5 disconnects the constant reference potential and connects circuits for providing a landing path as illustrated in Fig. 1.

Title: Improvements in or relating to electromagnetic couplings
IPC: H04N1/36
Filed: 1927-09-06
Abstract: 307,365. Fulton, O. Sept. 6, 1927, synchronous movements.- In a copying. telegraph receiver, in which a revolving drum supporting the received picture is brought to rest for synchronization at the conclusion of each revolution and is restarted by a signal from the transmitter, an electromagnetic clutch couples the drum to the drive, a switch operated by a received signal completes an energizing circuit of the clutch, and the clutch is automatically disengaged to stop the drum when it is to be at rest. As shown, the magnetic clutch connects a gear wheel D, which drives the drum, to a spindle A driven by a motor. When a magnet M1 is energized by the action of a relay A it attracts its armature B which releases a stop Z and closes a contact K. This closes the circuit of the winding of a magnet M which attracts and holds an armature An which is fixed to the spindle by a tappet N. The driving gear wheel and associated parts therefore begin to rotate and during rotation the contact K is short circuited through a slip ring S2 until, immediately before the completion of a full revolution, a brush E reaches an insulating part I on the slip ring. The magnetic clutch then disengages and the apparatus ceases to revolve. The apparatus is locked in the position of rest by connecting to the rotatable parts of the apparatus a disc which is provided at one point with a recess into which fits a projection on the armature of an electromagnet operated as described above (Fig. 2, not shown). Specification 199,349 is referred to.
