Title: A method and means of preparing designs on surfaces
IPC: B44D2/00
Filed: 1958-12-16
Abstract: 945,468. Ornamenting. F. PAYNE. March 15, 1960 [Dec.16, 1958], No. 40524/58. Heading B6G. A design is produced on a glazed (e.g. white) base by applying to the whole or part of the surface a paint constituted by a synthetic detergent, which may be burnt either before or after application or during the working up of the design to a black colour, and working up the design by a rubbing tool. Dry detergent may be heated over a flame until black, and water and optionally liquid detergent may be added. The paint may be removed and re-applied or replaced by fresh paint, and the design may be finally coated with varnish or shellac. A carbon deposit from a flame may be applied. The paint may also be made by mixing equal volumes of powdered and liquid detergent and adding either a mixture of vinegar and sugar or a mixture of tea and water. The glazed surface may be preheated and a carbon deposit applied from a flame, excess being removed by a brush. A second deposit of carbon may be applied, and colour pigments or paints applied in selected areas. Colour pigments may be washed off by lighter fuel, leaving the carbon deposit. A second application of the paint may be made to the transparent coating over the design.

Abstract: 982,160. Valves. H. VAILLANT, [trading as JOH VAILLANT K.G.]. Nov. 5, 1962 [Nov. 10, 1961; March 31, 1962], No. 41791/62. Heading F2V. A moving closure member 5, Fig. 2, which is urged to its seat by a spring 4 and the inlet water pressure, is opened by a stem 13 through a " click-stop " device. The stem 13 which abuts the member 5 embodies a cylindrical head 13<SP>1</SP> rotatably supported in an element 11 which is axially slidable but prevented from rotation by a fork 25 engaging a pin 26. A stud 14 on the stem 13 is disposed between two body parts 18, 18<SP>1</SP>, Fig. 3, the opposed faces of which have cam surfaces. The element is pushed to open the valve and the stud 14 leaves a point 15 on part 18, traverses an edge 17 and moves along an edge 19 of part 18<SP>1</SP> at the point 20 of which it is urged by the spring 4 to a point 22 of part 18. Subsequent pushing on the element 11 causes the stud 14 to follow a similar path and finish at a point 23 on part 18 wherein the valve is closed. Such movement of the valve is accompanied by rotation of the stem 13 which through a cutout portion of the element 11 and pair of marks on the head 13<SP>1</SP> enables the valve position to be determined. If the indicator is located away from the element 11 it is driven by gearing from the stem 13. Two such valves may be used with a water heater for supplying cold water thereto and removing hot water therefrom.

Abstract: 1523015 Blood pressure measurement PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Oct 1976 [17 Oct 1975]  42733/76 Heading G1N(E). In a blood pressure measuring device the relative magnitude of the A.C. and the D.C. components of the electrical output signal of a blood pressure transducer are altered so that the A.C.'s signal relative magnitude is increased. In Fig. 1 two separate identical signals are provided at the output of a blood pressure transducer to form two signal path 3 and 5. The first signal path 3 comprises a network consisting of a series capacitor 7 and an earthed resistor 9 which passes only A.C. components, while the second signal path 5 comprises a network consisting of a series resistor 11  and an earthed capacitor 13 which forms the average value of the presented voltage and hence pass only D.C. components. The second signal path also comprises an attenuating network of resistors 15 and 17. The signal paths supply a summing device 19 and an amplifier 21 whose output 23 may be connected to an oscillograph or a recorder. The component values are preferably chosen such that the attenuating factor N produced by the resistors 15 and 17 is equal to the amplifying factor N of the amplifier 21. Thus the D.C. signal is effectively unaltered in magnitude but the A.C. signal is amplified "N" times.

Abstract: 1,083,860. Phase detection circuits. HUGHES AIRCRAFT CO. Oct. 11, 1965 [Feb. 8, 1965], No. 42968/65. Heading H3A. In a system for receiving data signals having one of a plurality of distinct phases, the local oscillator is maintained phase locked despite the phase changes in the received signal. A system for receiving a signal having four possible equally spaced phases, Fig. 4, comprises phase detectors 50 . . . 55 fed from the local oscillator 58 with phase shifted reference signals. The two detectors 50, 51 produce four possible output combinations #A.#B, #A.#B, #A.#B, A.#B depending in which quadrant the data signal lies. For example with an input signal having a phase # 1  an output A.B is produced and is selected by the logic circuits 74 . . . 77 to produce an output at 78 which sets the switch 87 to connect detector 52 to the oscillator control circuit. The phasing of the reference signal to this detector is such that any deviation of the oscillator phase results in an appropriately phased oscillator control signal. Similarly with an input # 2 , the detector 53 produces the correct control and is accordingly selected by the switch 87. Arrangements for two phase and three phase signals are also described, Figs. 1, 6 (not shown).

Abstract: 1431253 Conveyers for garment storage and retrieval systems I WILLIS 4 Oct 1974 43079/74 Heading B8A Garments are stored on hangers on an endless conveyer and means are provided for preventing access to the remaining garments when feeding a garment to, or retrieving a garment from, the conveyer through an access opening. A system is described embodying three different types of conveyers with the portion of each conveyer at the access opening being shown in Fig. 1 in enlarged scale. At the left of Fig. 1 the garments are transported by wire mesh containers 101 (Fig. 2) carried by an endless chain 61 suspended from an overhead rail 62. The garment is suspended by a hanger in a container 114 which is mounted on rollers 116 within the container 101. This enables the container 114 to slide into and through an access chamber 124, when a door 45 of the latter is unlocked and pulled open. A cam surface 129 (Fig. 3) causes a member 133 connected to the door 45, to be flexed upwardly into engagement with the container 114. In a modification (middle conveyer of Fig. 1), a retrieval control means (Fig. 6, not shown) causes doors 105, 106, to be moved from the broken line, to the full line positions, when the required container 101 arrives and stops at the access opening. In the arrangement shown at the right hand side of Fig. 1, the rotating doors of the last embodiment are replaced by a wire mesh member 78. The latter is moved by an endless belt conveyer (86) (Fig. 5, not shown) into a full line protective position when the desired load is stopped at the access opening. The conveyer may be operated by the insertion of a magnetic code card (92) (Fig. 6, not shown) in a receptor 71 (Fig. 1). Alternatively, the conveyer may be controlled by means of coins fed to receptors 68, 69, or 71.

By switching the adder or the subtractor in dependence on the level of the input phase difference between the modulated and the local carrier signals, the demodulated output is maintained at a fairly constant level. Figs. 2, 3 (not shown) relate to the arrangements of blocks 50, 60 respectively.
