Abstract: 1264151 Invalid handling devices; endless conveyers; rolling appliance DIAMONDHEAD PROPERTIES Inc 30 Jan 1969 [14 Feb 1968] 5204/69 Index A5X 20 B8B and B8H A device for transferring an object from one location to another comprises a pair of superposed endless belts mounted in a frame and adapted to be inserted between the object and its supporting surface. In the embodiment shown in Fig. 1, the device 22 is mounted on a hospital trolley 20 for transferring a patient to and from a bed 48. Upper and lower endless belts 24, 26 are supported on rollers 28 in a frame 30. A pair of pinions 34 is provided on an extension of a roller shaft of the lower belt, one pinion engaging a rack 32 on the trolley whereby rotation of the pinion, by means of a motor 52 and a chain 36 passing around the other pinion, causes the device to be projected or retracted laterally of the trolley. The upper belt is similarly driven in the opposite direction by a motor at the other end of the trolley, there being no rack associated with the upper belt. As the device is moved into contact with a patient on the bed 48, the leading edge of the upper belt, which is rotating in an upward direction, lifts the patient on to the upper belt, the lower belt rolling over the surface of the bed. The motor for the lower belt is then reversed and that for the upper belt is stopped to retract the device to bring the patient over the trolley. The trolley 20 and device 22 may be adjustable vertically. In a further embodiment, Figs. 5, 6 (not shown), the device is projected and retracted by means of a double-acting hydraulic ram acting through an endless chain, whereby the lower belt is driven. The upper belt is mounted on rollers which are adjustably mounted whereby the leading edge of the upper belt may be lowered to engage a patient, in which position it is driven by frictional engagement with the lower belt, or may be raised to provide a cradle-like support for the patient, in which position it does not engage the lower belt. In the embodiment shown in Fig. 8, the transfer device is manually controlled and consists of a lower endless belt 168, passing around rollers 156, 158, 160, 162 mounted in a frame 152, and an upper belt 166, passing around a roller 154 in the frame and a roller 164 mounted on a bar 172 pivotally supported on the frame. In operation to load an object such as a patient on to the device, the bar 172 is pivoted in the direction of the arrow to tighten the upper belt and to produce frictional engagement between the belts. As the device contacts a patient on the bed, the upwardly moving leading edge 174 of the upper belt causes the patient to be lifted on to the upper belt. The bar 172 is then pivoted in the opposite direction, to slacken the upper belt and disconnect the frictional contact between the belts, so that the device can be moved whilst supporting the patient. The procedure is reversed to unload a patient from the device.

Abstract: 1304188 Data transmission PLESSEY CO Ltd 2 Dec 1970 [9 Dec 1969] 59911/69 Heading H4P A modulator for generating differential phase shift signals in a data transmission system comprises two balanced modulators 10, 12 which are fed with carrier and carrier phase displaced by 90 degrees which are modulated by sine and cosine signals A, B, the resultant output signal Z from the modulators is a signal of constant amplitude but of varying phase which varies in dependence upon the frequency and phase of sine and cosine signals, which in turn is dependent upon the input data signal. The data arrives on line 37 in two-amplitude, two-polarity form and is converted to two parallel polar signals a, b. Signal b determines the frequency of clock pulses from unit 34 fed to a counter 32 and signal a the direction of counting. The clocked counter 32 gates successive amplitudes from resistor chains 24, 26, to build up in steps the sine and cosine signals, which are smoothed by filters 18, 20 before modulation. The output signal Z advances or retards in phase by 45 or 135 degrees according to the four states of the input signal. Further data, on line 44, may be transmitted by varying in modulator 42 the rate at which clock pulses are fed to the counter 22 so varying the rate at which any phase change dictated by the data on line 37 takes place. A counter with fewer stages may replace counter 22 by employing a square wave supply to the resistor chains which changes state as the counter recycles (Fig. 4, not shown).
