Title: Door closers
IPC: E05F3/10
Filed: 1963-11-15
Abstract: 1,044,168. Door closers. JOSIAH PARKES & SONS Ltd., D. S. MAITLAND and G. L. TREDWELL. Feb. 15, 1965 [Nov. 15, 1963], No. 45134/63. Heading E2M. In a door closer for swing doors in which a check device is arranged between an actuating member such as the rotary cam 15 and a spring means such as 26 for loading the actuating member, the check device comprises a pair of piston assemblies each comprising a pair of pistons 12, 13, slidable in an associated bore 11 and urged apart by resilient means 14, each assembly being provided with one-way valves 33 to admit hydraulic fluid to the space between the pistons and restricted passage means 34 to allow the fluid to escape gradually from the said space. The cam 15 is connected by its spindle 17 to a swing door at the rotational axis thereof. A pair of follower arms 18 pivoted about a fixed common pivot 19, have rollers 20, 21 for engaging the cam 15 and the pistons 12. The pistons 13 are engaged by abutments 22, one of which is adjustable and which are carried on a slide member 23 having a tubular stem 24 sliding in a central bore and housing a spring 26 acting between an annular abutment 27 and an abutment 28 adjustable on a tension rod 29 anchored at 19. As the cam 15 is turned clockwise from the door closed position in Fig. 1, the right-hand piston assembly acts as a rigid member on the slide member 23 to load the spring 26, whilst the pistons of the other assembly move apart and fluid enters the space between them. On releasing the door the slide 23 moves upwards tending to close the door, and the left-hand pistons at first move upwards in spaced relation but as the cam approaches the door-closed position the left-hand pistons approach each other and the fluid is gradually expelled from the interspace through the bleed port 34. Grooves 36 on the pistons 12 allow fluid to escape after the lower end of the piston 12 passes the bleed port 34. The cam 15 may be rotated through a further 90 degrees from the 90 degrees open position, such motion being restricted by the pistons of the left-hand assembly being forced together against the action of the fluid present in the interspace. The cam 15 and the arms 18 are arranged so that the door is retained in the 90 degrees and 180 degrees open positions until a closing movement is initiated by hand. Relief ports 37 in the bore 11 prevent overloading if the door is forcibly closed or further opened from the 90 degrees open position.

Title: Improvements in or relating to Bandwidth Compression Systems.
Inventor: FLANAGAN JAMES LOTON
IPC: G10L11/00
Filed: 1967-10-11
Abstract: 1,188,014. Bandwidth compression. WESTERN ELECTRIC CO. Inc. 11 Oct., 1967 [1 Nov., 1966], No. 46392/67. Heading H4R. In a bandwidth compression system the speech signal is split into a number of contiguous frequency bands to provide a subsignal S(t) which is treated as the real part of an analytic signal, # (t) = s(t) + j###S(t) where #S (t) is the Hilbert transform of s (t), and the signal which is transmitted is the real part of the square root of the analytic signal which is shown to be where a (t) is the instantaneous amplitude of the analytic signal # (t), and # (t) = a (t) ej# (t). The signal transmitted is limited in frequency band to half the input frequency band and is a signal from which the original frequency band may be synthesized. As shown in Fig. 1 the input speech band is split into contiguous frequency bands by filters 100, having a bandwidth such that no filter contains more than one formant. The resulting channel signals are applied to Hilbert transform networks 102, comprising appropriately adjusted transversal equalizers, and to a delay 101 of value equal to the delay imposed on the signal in network 102 to produce appropriately synchronous value s (t) and #S (t) from which, by squaring, adding, and square rooting, in 103, 104, 105 and 106 the instantaneous amplitude of the analytic function is derived. The resulting signal, a (t), is added to the original signal, s (t), in 107, multiplied by ¢ in 108, and the square root taken in order to obtain the real part of the square root of the analytic signal. To resolve the ambiguity introduced by the square rooting a switch 111 is arranged to invert the output of 110 every time signal s (t) goes through zero when the signal s (t) is positive using the circuit described with respect to Fig. 3 (not shown). It is shown that the original signal s (t) may be obtained from the transmitted real part of the square root of the analytic function simply by producing the imaginary part of the square root in Hilbert transform network 114, delaying the real part in 113 to synchronize it with the imaginary part, squaring both parts in 115 and 116 and taking the difference in 117. The resulting signals from the similar channels 1 to N are added in 10 and reproduced at 11. In a modification Fig. 4 (not shown) the amplitude of the real part of the analytic signal is restored to its original amplitude, a (t), prior to transmission by multiplying the output of the square root network 110 by the output of a similar square root network connected to the output of square root network 206. At the synthesizer the output of the subtractor 117, which is now a (t) s (t), is divided by a signal, a (t), derived by adding the outputs of networks 115 and 116 and taking the square root. The arrangement is said to produce instantaneous frequency division.

Patent GB-478744-A (GB)
Abstract: 478,744. Echo - sounding apparatus. HUGHES & SON, Ltd., H., and SPROULE, D. O. July 30, 1936, No. 21073. [Class 118 (ii)] In an echo-sounding system in which an oscillatory member, oscillating synchronously with the emitted pulses, is used to enable the instant of receipt of the reflected pulse to be ascertained visually, the oscillating member and the pulse emitter are electrically controlled by mechanically coupled switches. The pulse responsive device may be a flashing lamp but is described as a magnet which co-operates with a number of elastic cantilever elements arranged adjacent the scale. The oscillatory member may be a cantilever or a swinging beam. As shown motor o drives cams n and m which control the emission of the pulses and energization of magnet l respectively. When magnet l is energized the bar a is attracted and spring q is compressed. Cam m opens the circuit of magnet l at or near the moment of emission of a sound pulse so that spring g swings bar a about pivot b against the action of restoring spring r. Bar a carries magnet d close to the array of elastic cantilevers h so that when the echo is received by receiver f, some of the cantilevers h are displaced and their whitened or silvered surfaces h<2> are visible in the slot h<3> so that their positions can be ascertained on scale t. The bar is restored by spring r and is held by magnet l until the next pulse is emitted. Specification 454,569 is referred to.
