Title: Analogue-to-digital converters
Inventor: MCNEILLY JOSEPH HOOD
IPC: H03M1/00
Filed: 1966-11-09
Abstract: 1,135,684. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 9 Nov., 1966, No. 50127/66. Heading G4H. In an analogue-to-digital converter of the kind in which the input signal is applied to a plurality of inter-coupled multi-stable devices, each having a different switching level, the devices being caused to set in a pattern representing the input value by a damped oscillatory waveform superimposed on the input, there are provided additional means for controlling the initial amplitude of the damped oscillatory waveform in response to the value of the input signal so that if the range of analogue levels to be coded is divided into octave groups, Fig. 3, the initial amplitude of the oscillatory waveform is similarly related to groups of input signal amplitudes. The converter comprises a coder 1, Fig. 1, an inverter 2, a mixer 3 and the damped oscillator 4. The input is from a multiplexer 5, amplitude samples passing in turn to the coder 1 having the damped oscillation superimposed on it by mixer 3. Coder 1 generates digit outputs on lead 8, as described in Specification 1,046,792, and provides a feedback signal which is inverted at 2 and effectively subtracted from the input by the mixer 2. Only the first four bits are necessary for a companding system, the first of each group of four defining the octave and the others the value within that octave, as shown in Fig. 3. It is desired to have these four bits in the first four time slots of the conversion period. This is achieved by making the amplitude of the damped oscillation constant within each octave, but doubling it at the beginning of the next higher octave (Fig. 4, not shown). The same oscillation amplitude is used for the first two octaves. The first half-cycle of the oscillation is replaced by a prepulse proportional to the amplitude of the input and the resulting output from the coder 1 is used to shock excite the tuned circuit 4. After the first two octaves, i.e. at level 15, the amplitude of the prepulse increases to enable digit 5 of the encoder. The feed-back signal is stored in peak store 11 and gated at 14 by a delayed sampling pulse, to the tuned circuit 4. For values in octaves 1 and 2 the output of the peak store 11 is prevented from reaching the circuit 4 by a slicing diode 13 having a level such that no signal passes to circuit 4 unless the input value exceeds level 15. The prepulse is generated by circuit 9, triggered by the sampling pulse and controlled by the input signal level so that it switches on digit 5 when the input is 16 digit 6 when the input is 32 and so on. Specification 1,039,341 is also referred to.

Abstract: 1464852 Cabinet beds SLUMBERLAND GROUP Ltd 1 Feb 1974 [1 Nov 1972] 50282/72 Heading A4J A foldable bed with a mattress has upper 11 and lower 12 link means pivotally connected to a support 10 the upper means being connected above the lower means and being longer than the lower means. Both means depend from the support 10 when the movable part 3 of the bed is in its storage position and both are pivotally connected to that portion of the movable part that is lowermost when the movable part is in its storage position. When the movable part is moved from its storage to its use position said link means and said movable part portion swing away from the wall 2 and the portion rises. As the movable part is moved between its positions of use and storage the centre of gravity of the movable part rises and falls again so that when the movable part is near either one of those positions gravitational forces urge it towards that position In the embodiment shown, the support 1 comprises a back panel 5, a top panel 9 and side panels 7. Attached to each side panel 7 is a vertical bar 10 to which is pivoted upper and lower links 11, 12 which are pivoted at their other ends to a bar 15 attached to the mattress carrier 3. Each leg 20 is pivoted to the carrier 3 at 22 and has a plate 21 to which is pivoted a bar 24 which, when the bed is stored, causes the leg 20 to swing up against the carrier 3. A latch arrangement Fig. 1 may be provided in which a foot lever 26 is pivoted sideways to draw down a further lever to which are attached rods 39 which disengage the latches.

Filed: 1973-10-30
Abstract: 1435620 Refrigerators F KNOPSMEIER 30 Oct 1973 [30 Oct 1972] 50410/73 Heading F4H A refrigeration system for use with a transport container comprises a compression system and an absorption system having separate closed cooling circuits, the coolant of the compression system being used for cooling the coolant of the absorption system. The compression system operates when there is power available to drive the compressor and, in the absence of such power, the absorption system takes over by drawing coolant from a reservoir, passing it through an evaporator and into an absorber where it remains until it is returned to the reservoir during the next operation of the compression system. As shown, the compression system comprises a compressor 7, a condenser 9, a receiver 13, a throttle 15, an evaporator 5, a heat exchanger 17, and a cooling coil 19 in the insulated reservoir 20 of the absorption system. The absorption system comprises an absorber 21, having a heater 22, a condenser 10, the heat exchanger 17 and the reservoir 20, and employs lithium chloride as the absorbent and methyl amine as the coolant. When the power is on, the compression system operates and the cooling coil 19 maintains the condensate in the reservoir 20 at a desired low temperature. During this time, the heater 22 operates and drives off gaseous coolant from the absorber 21 to the condenser 10 and heat exchanger 17, the resulting condensate passing to the reservoir 20. If the power supply fails or is disconnected, liquid coolant passes from the reservoir 20 to the throttle 28 and evaporator 4 and thence to the absorber 21 where it is absorbed. For rapid storage of coolant in the reservoir 20, or when coolant passing through the heat exchanger 17 from the evaporator 5 has insufficient cooling capacity, condensate is drawn from the line 12 between the condenser 9 and receiver 13 and passed through a throttle 31, controlled by a thermostat 32, to the heat exchanger 17 where it evaporates and cools the coolant of the absorption system and then passes through the coil 19 back to the compressor. The compressor may be switched on and off by a thermostat in the chamber 2 which thermostat may also control valves upstream of the throttles 15 and 28. The compressor may be switched off by level switches in the receiver 13 or reservoir 20. A magnetic valve may be provided in the riser pipe 27 from the reservoir and arranged to be closed when the compressor is operating. In a second embodiment, Fig. 2 (not shown), the absorber is heated by hot coolant passing from the compressor to the condenser. Constructional details of two absorbers are described and illustrated, Figs. 3, 4 (not shown).

The sulphur trioxide produced is absorbed in the dilute sulphuric acid, the elemental sulphur produced is suspended in the acid, the carbon dioxide produced passes into the waste gases and the water produced either passes into the waste gases as vapour or is absorbed by the acid. The peroxydisulphuric acid used is produced by supplying fresh dilute sulphuric acid, free of peroxydisulphuric acid, to an electrolytic process, and the resulting electrolyte acid containing peroxydisulphuric acid, is mixed with the dilute sulphuric acid to provide the acid for treating the gas. The peroxydisulphuric acid and sulphuric acid derived from the sulphur trioxide are withdrawn together with the dilute sulphuric acid after treating the waste gases. The process may be used for removing sulphur dioxide, sulphur trioxide and sulphuric acid mist from the waste gases from a contact process plant for producing sulphuric acid.
