Abstract: A multi-element lens system has a central cavity (24) containing a heavy, high index gas such as a haloalkane. The central cavity is defined by two of the lens elements (B,C) and the gas in it acts as a thick positive lens. The pressure of the gas in the cavity is varied in response to magnification changes desired, the pressure change causing a change in the refractive index of the gas thereby altering the focal length of the lens.

Abstract: Aqueous compositions, suitable for printing, are described which have a high volume solids content. They comprise primary polymer particles and a secondary polymer which provides temporary adherence of the particles to a substrate before the primary polymer is fused by a heating step, in a printing process, in order to cause permanent adherence. There are advantages over the use of organic solvent-based and other aqueous compositions, such as easier cleaning, low toxicity/fire hazard and lower cost.

Abstract: An envelope generator (20) used in an electronic musical instrument, such as an electronic organ, includes dual charge pumps to form the attack and decay portions of the envelope. The envelope generator is arranged to be connected to the envelope control input of a keyer (32) and the other input of the keyer is connected to a tone source (34). When the appropriate key of the keyboard (10) is depressed, a source of input voltage is connected to the input of the envelope generator (20) and a first charge pump (54) incrementally transfers the input voltage to a capacitor (74) over a first sequence of discrete time frames. A second charge pump (156) connected serially between the first charge pump and the envelope input of the keyer incrementally transfers the voltage on the capacitor (74) to another capacitor (106) over a second sequence of discrete time frames. This arrangement has the effect of reducing the magnitude of the discrete steps thereby avoiding audible distortion associated with prior envelope generators including only a single charge pump. The second charge pump may be a dual phase (130) charge pump so that the effective frequency ratio between the second and first charge pumps is doubled.

Abstract: A line synchronizing circuit for a picture display device comprising a control loop for controlling a line oscillator. An incoming line synchronizing signal and also a reference signal generated by the oscillator are applied to a phase discriminator. The output signal of the phase discriminator is smoothed to obtain the control voltage for the oscillator. Pull-in of the control loop is established by means of a coincidence detector. Prior to that an edge of the reference signal is compared with the centre instant of a line synchronizing pulse. When the control loop is in the pulled-in state it is changed by the coincidence detector to compare the leading edge of a line synchronizing pulse to the centre instant between the said edge of the reference signal and its first preceding edge.  r

Abstract: A unitary disposable conduit extends from the intravenous reservoir along a gravity-flow path to the patient, and incorporates a valve block containing an externally controlled flow-control valve. An electronic controller monitors the drop rate in a drop chamber which is an integral part of the disposable conduit, compares this rate with an operator-selected rate, and controls the valve by varying the current in a shape-memory actuator element whose movements, caused by the resultant Joule heating, are coupled to the valve to proportionally vary the flow rate in the conduit. The valve block is securely received within a recess in the controller, and is automatically coupled to the controller when inserted within this recess. The shape-memory actuator element may be incorporated within the disposable valve block, or may form a part of the controller, with a simple mechanical coupling to transmit its movements to the valve. The valve may be automatically or manually closed when the valve block is removed from the controller, or if power failure occurs.

Abstract: In an automatic process for the continuous prodn. of quilted fabric, several layers of superposed material are simultaneously withdrawn from supply rolls ranked at one end of the line, and the extended sheets are clamped together transversely on either side of a sewing station where a sewing head, which is freely movable in two dimensions sews them together using a repeated pattern of closed figures. When the sewing of one length is completed, the clamps open and the next length is drawn into the sewing station. Whilst the new length is being sewn the sheets are cut transversely to sever the previously-sewn length, and the jaws which advance the sheet move back to grasp the new cut edge. This is a fast, continuous and fully automated process which replaces slow, expensive and heavily labour-intensive prodn. methods.
