Title: Timedivision switching networks
IPC: H04Q11/04
Filed: 1972-10-06
Abstract: 1366255 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 6 Oct 1972 [12 Oct 1971] 46114/72 Heading H4K A network for channel switching between incoming and outgoing T.D.M. highways comprises a plurality of independent parallel connected time division network portions connected to the same space division portion, groups of one or more time division portions being served by corresponding control and speech memories the number of storage compartments normally accessed in the control and speech memories being respectively equal to twice the number and the number of channels switched by that group. The object of the invention is to reduce blocking conditions. In the embodiments the space division network is expanded to make the system non-blocking. In the P.C.M. system shown a three stage space division network is located between two time division switching stages. The space division network is divided into two separately controlled parallel sections 39, 40 and the time division stages are each divided as indicated at 53 and 54 into two or more normally independent parallel sections for security purposes. Each incoming section 53 serves a group of 4 incoming highways, each with 32 time channels, i.e. it serves 128 channels. The speech store 24 of an incoming section has 128 storage locations in a first portion 24a to provide intermediate storage for the 128 channels. An additional storage portion 24b provides an additional 128 storage locations not normally used but provided so that a section can take on in addition the work of an adjacent section under fault conditions. The control store 20 has 256 locations cyclically accessed by a clock 22, and under normal conditions only 128 of the locations stored addresses of locations in section 24a of the random access store 24, the particular locations involved being dependent of the connections required at that time. The output sections 54 operates in similar fashion to the input sections 53. Under fault conditions in which a section takes over the service of an adjacent defective section, all 256 locations in store 20 store addresses of locations in store 24, the system then functioning as a conventional system with higher blocking risk.

Title: Improvements in or relating to personal calling radio receivers
Inventor: WARDEN CHARLES ALEXANDER
IPC: H03F1/02
Filed: 1961-12-28
Abstract: 960,654. Personal signalling receivers. MINISTER OF AVIATION. Dec. 18, 1962 [Dec. 28, 1961], No. 46396/61. Heading H4L. A personal signalling receiver including an R.F. amplifier, a demodulator and an A.F. amplifier has a selector means responsive to a personal call signal and switching means which control part of the A.F. amplifier so that either it is caused to act as an oscillator on receipt of the call signal by the selector or it amplifies the signal from the demodulator. The transmitted carrier frequency is picked up by a coupled ferriter rod aerial 1 and is fed to R.F. amplifier 2, consisting of an oscillator mixer stage Q1, two I.F. amplifier stages Q2 and Q3, and at its output a detector stage D1 The output of detector stage D1 is applied to selector device 3 with two tone amplifier stages Q4 and Q5 driving a reed unit 8, 9 and 10 whose reeds 9 and. 10 are tuned to a single tone frequency or two separate tone frequencies comprising the characteristic call signal. When these reeds resonate together H.T. is applied to energize a double relay T/1 resulting in the closure of contact T1. The relay is locked by switch S1(b) in the position illustrated. The A.F. amplifier 5 has an amplifier stage Q6 and a push pull output stage Q7, Q8 whose output is applied to loud-speaker 6. A positive feedback connection 7 is taken from the output to a switch S1(a) which in the position shown applies positive feedback to the amplifier input converting 5 into an oscillator. Operation of stage 5 as an oscillator occurs on closure of relay T1 since H.T. is then applied to the relevant parts of circuit 5. On hearing the alarm signal at loud-speaker 6 the called person manually changes the switches S1(a) and S1(b) (normally ganged together) to their second positions. Changeover of switch S1(b) releases the relay T/1 and applies H.T. direct to stage 5. The movement of switch S1(a) to its second position, however, breaks the feedback line 7 and connects the output of detector stage D1 to the input of stage 5 which now functions as an A.F. amplifier to provide the operator with transmitted speech intelligence. A modification of the circuit is described, Fig. 3 (not shown), in which the unit 4 responds only to the sequential alternate reception of two different tones. A volume control is also provided.

Abstract: 1,165,962. Assembling force fits. A. G. BODINE. 19 Oct., 1966, No. 46798/66. Heading B3U. [Also in Division F2] An apparatus for inserting a bushing 135 into a cylindrical casting or other machine part 131 with a bore 134 comprises an hydraulic ram 126 which forces the bushing into the bore and means to subject one of the parts to continuous and sustained vibration. The vibration of the bushing 135 is attained by a horizontal steel beam 140 which is set to vibrate in a vertical plane and is supported from a beam 148 at the nodes. At each end of the beam 140 is an air-driven oscillator 158 which comprises a sleeve (160), Fig. 5 (not shown), on which an inertia ring (165) is mounted and made to rotate about the pin in a vertical plane to set up the vibrations (see Division F2). The vibrations are transmitted from the beam to the bushing 135 by an adapter 141 mounted on the beam at a point spaced from the antinode. The casting 131 is clamped between an adjustable pad 180 and an adapter 185 associated with a beam 188 which is made to vibrate by oscillators at each end in a similar manner to the beam 140. An hydraulic ram 210 extends from the side 125 of the press 120 so that force fits can be performed horizontally. With the above apparatus the bushing is made to vibrate longitudinally whereas the casting vibrates in an elliptic mode. The apparatus may be used with only one beam in sonic vibration or the beams may be vibrated simultaneously at the same frequency or different frequency and in phase or out of phase. The vibration frequency is stated as being sonic but is not limited to the human audible range. Reference has been directed by the Comptroller to Specification 1,030,448.

Abstract: 992, 522. Hydraulic balances. H. STOFFLER. Dec. 13, 1962 [Dec. 18, 1961], No. 47058/62. Heading G1W. An hydraulic balance in which a load to be measured is applied to liquid in a space a to displace a first piston f in a first cylinder c and thus cause a second piston e to be displaced in a second cylinder e<SP>1</SP> against a further load e.g. a spring, pendulum, or beam balance to an extent depending on the relative values of the loads the first piston f is arranged to control the supply to the second piston of liquid from a source h<SP>1</SP> under a pressure which always exceeds that in the space a, so that the amount of liquid supplied to the second piston e exceeds that displaced by the load to be measured, the first piston being arranged to ensure that liquid from the source h<SP>1</SP> is continuously supplied to the second cylinder during measurement at a rate depending on the position of the piston f relative to the first cylinder. In use the load to be measured is applied acting through a diaphragm to move the piston f to the right in Fig. 1. Liquid from the source h<SP>1</SP> is fed to the cylinder c via an inlet h, and leaves by way of a channel i to the second cylinder e<SP>1</SP>. The channel i also communicates, with a channel d, so that liquid passing therethrough also acts in the piston f, subsequently leaving via a discharge channel K. As the piston f moves to the right under the influence of the pressure in the space a, the channel k closes increasing the pressure in the channel d until it equals that in the space a. This pressure is communicated to the piston e the movement of which is arranged to indicate the load to be measured.

Abstract: 1,061,828. Hydraulic brakes. KELSEYHAYES CO. Nov. 15, 1965 [Nov. 27. 1964], No. 48446/65. Heading F2F. In a pressure proportioning device adapted to be interposed between the master cylinder 10 and the rear wheel brake cylinders 28 of the hydraulic system of a vehicle, a housing 20 comprises first (46) and second (56) pistons adapted to move concurrently to displace fluid to the rear wheel brake cylinders, the first piston 46 being arranged for actuation by fluid pressure from the master cylinder 10 via connection 18 and inlet opening 22, variable force transmitting means in the form of a multiplicity of levers 68 connected between the first and second pistons to move the second piston 56 in a direction displacing fluid to the rear wheel brake cylinders 28 in response to movement of the first piston 46, the variable force transmitting means being automatically variable to change the mechanical advantage when the first piston continues to move under the influence of increasing master cylinder pressure. A by-pass means 84, 94 is provided to supply fluid directly via passageway 110, the space between a valve member 94 and a bore 84 in the by-pass device and via open valve 98 into passageway 112 to the outlet connection 24 of the pressure proportioning device and via connection 26 to the rear wheel brake cylinders to provide direct fluid communication from the master cylinder 10 to the rear wheel brake cylinders during the predetermined initial brake application. After the initial brake application the by-pass connection closes and the first piston 46 of the pressure proportioning device is exposed to the master cylinder pressure and moves to the right which results in the integral flange 50 moving also to the right in the bore 34 to actuate the levers 68 allowing them to fulcrum against a convex surface 72 of a pivot block 64 which bears against an inner face of a flange 40 forming the end member of the pressure proportioning device 20. The movement of the inner ends of the lever 68 moves a piston rod 60 to the left; thus, fluid from master cylinder 10 acting only on piston 46 produces movement of both pistons 46 and 56. The arrangement is such that a gradual lowering of the ratio of rear wheel brake pressure to the front wheel brake pressure occurs as the master cylinder pressure is increased since as the fulcrum point of the levers 68 with the curved pivot block 64 moves radially outwardly, an increased movement of the piston 56 for a given movement of the piston 46 will result and a decreased mechanical advantage is achieved due to the fact that a greater force acting against the outer ends of the lever 68 is required to deliver a given force to the piston 56 for use in pressurizing the fluid in the bores 34 and 38.
