Abstract: 723,297. Mounting detachable wheels. FLEISCHANDERL, R. Dec. 29, 1952 [Jan. 4, 1952; Oct. 28, 1952]. No. 32896/52. Class 144 (1). A tool for facilitating mounting of a detachable wheel on a wheel hub comprises a rod, to pass through one of the bolt holes in the wheel, having articulated at its end a sleeve to fit over one of the fixing studs on the hub, the rod providing for lifting of the wheel and guiding thereof onto the sleeve. Figs. 3 and 4 show two rods 25 each having a ballend 26 universally coupled to a protective sleeve 24 which fits over a wheel-fixing stud 23. The rods are shown in use during mounting of the outer wheel 11 of a twin-wheel assembly, additional support of the wheel being provided by a stay bar 12 engaging under the wheel rim and detachably connected to the wheel by a hook-ended spring 13. The bar 12 prevents undue tilting of the wheel as the bars 25 are raised to slide the wheel onto the sleeves 24 thereby passing the bolt holes in the wheel over the aligned wheel-fixing studs. The stay bar 12 may be hollow to accommodate its securing spring 13, a line extension of which passes through a transverse hole in the bar. To hold the inner wheel 16 of the twin assembly against tilting during the mounting of wheel 11 a detachable stop rod 15 is engaged in a transverse hole 17 in the wheel hub to extend vertically downwards. For bolt-less or stud-less wheel hubs the sleeves 24 of the rods 25 may have fixed or detachable studs therein to engage in the tapped holes in the wheel hub and allow the wheel to be aligned and bolted on the hub.

Filed: 1967-07-18
Abstract: 1,162,279. Machinery safety devices. AMETEK Inc. 18 July, 1967, No. 32972/67. Heading F2J. [Also in Division D1] In a garment pressing machine, a combined exhaust and safety device comprises a hood 32 which is substantially the same shape as a pressing head 20 on which it is resiliently mounted, and control means are responsive to sensing of an obstruction by the lower edge of the hood 32 so that the pressing cycle is then interrupted and the pressing head 20 restored to its open position by springs 30. The control means includes ball valves 50 mounted on the hood 32 and adapted to be engaged by corresponding actuator pins 52, mounted on the head 20, on tilting of the hood 32 with respect to the head 20, thereby venting a compressed air supply to an actuating piston 28 and cylinder 26. To start the machine, an operating lever 62g is actuated to displace a valve 62f and allow compressed air from a supply line 58 to pass via conduits 64, 66 to a diaphragmoperated control valve 56, thereby causing movements of plunger 56d, rocker 56e and plunger 56f and putting line 58 in communication with a conduit 60 to supply compressed air to cylinder 26. Compressed air from supply line 58 is also supplied via conduit 58b, valve 76 and conduit 70 to a release valve 72. If movement of the hood 32 is obstructed, tilting thereof occurs and one of the valves 50 is opened to vent the conduit 70 to atmosphere whereby release valve 72 vents conduit 66 to atmosphere and valve 56 shuts off the supply of compressed air to cylinder 26. In a modification, the lower edge of a press hood 32, Fig. 8, comprises a tubular sensing element 80, containing a fluid F, which is in communication with a valve 88 and a diaphragm-actuated switch 92 which controls a switch 94 in the supply circuit 96 of a solenoid valve 98. When the sensing element 80 meets an obstruction, there is a flow of fluid into valve 88 which actuates valve 92 to open switch 94 and cause valve 98 to vent the compressed air supply to atmosphere.

Title: Improvements in or relating to television systems
Inventor: BASS PATRICK
IPC: H04N7/16
Filed: 1962-08-30
Abstract: 1,028,025. Television. R. & R. RESEARCH Ltd. Aug. 26, 1963 [Aug. 30, 1962], No. 33385/62. Heading H4F. In a transmitter for a subscription television system, Fig. 2, the signals are rendered secret by the generation of additional line synchronizing D.C. pulses not having video synchronization significance when the level of the video signals is representative of black and by the conversion of the line synchronizing pulses of the standard waveform into bursts of alternating current. A standard television signal, Fig. 4a, is applied to terminals 10, 11 and fed to picture/ synchronizing signal separator 12 in which the video signals and the synchronizing signals are separated on to lines 13 and 14 respectively. When the depth of the picture signal is representative of black, i.e. areas 34, 35, circuit 19 triggers pulse generator 17 to produce D.C. pulses 44, 45, Fig. 4b, and when each synchronizing pulse 30 is applied to burst modulator 21 a burst 40 of alternating current is produced. The signals are then combined by device 15 and made available for transmission between terminals 22, 23. The receiver for this system is arranged first to receive by wire or radio the modulated carrier-wave, amplify and demodulate the same to provide a signal having a waveform of the kind shown in Fig. 4b for application between terminals 50, 51 of Fig. 3. The video signals are separated from the D.C. pulses and A.C. bursts on to lines 53 and 54 respectively by device 52 and filter 55 passes only the A.C. bursts to demodulator 57 so that they appear on line 58 as D.C. pulses. The reestablished line synchronizing pulses and the video signals are combined in device 59 to produce a waveform of the kind shown in Fig. 4a and applied to a conventional television display. The additional D.C. pulses may be analogous to the frame synchronizing pulses of a normal television transmission, the frame synchronizing pulses being transmitted as A.C. bursts. The A.C. synchronizing pulses 40 may extend into the grey level instead of lying wholly within the blacker than black level. To increase the unintelligibility of the pictures reproduced before payment the video signals may be modified to indicate black level at additional instants not determined by the picture transmission preferably towards the side edges of the pictures. The frequency of the A.C. bursts may be modulated with programme announcements and price.
