Filed: 1971-07-09
Abstract: 1308883 Laminating J R MORRISON 9 July 1971 [3 March 1971] 32314/71 Heading B5N [Also in Division B6] A decorative article is produced by as shown in Fig. 5 (a) providing a base 10 having a surface bearing a pressure-sensitive adhesive coating 15, (b) applying a portion of a narrow strip 11 of flexbile material to the surface so that the strip portion adheres thereto, the remainder of the strip being held away from the surface, (c) pressing a knife-edge 22 against the strip in the region of the strip between the portion adhering to the surface and the remainder of the strip, the knife pressure being in a direction perpendicular to the plane of the base surface to cut the strip to a desired length, and (d) repeating steps (b) and (c) using other strips of flexible material, each successive strip applied to the surface being contiguous with at least one strip preceding it, at least some of the strips having a visible characteristic different from others of the strips, whereby all of the strips together produce a composite decorative effect. The base 10 may be of rigid material, e.g. thick cardboard, or a flexible sheet, e.g. stiff cloth. Preferably the upper surface of the base bears indicia which may be printed on it to guide the user in placement and cutting of the strips 11 on the base and to indicate the type e.g. colour of the strip to be used. Initially the adhesive coated surface of base 10 may be covered by a protective layer which may be in the form of separate sections, each being several times as wide as one of the strips 11, so that the entire adhesive coated surface need not be uncovered at once. The strips may differ in colour or texture and may all be of the same material, e.g. cloth, paper, wool, plastics, or the material of some strips may differ from that of others.

Abstract: 1341934 Vapour generators COMBUSTION ENG Inc 11 July 1972 [13 July 1971 21 April 1972] 32427/72 Heading F4A A vapour generator of the shell and tube type comprises a pressure vessel which defines a vapour generation chamber 30, a bundle of heatexchange tubes 38 enclosed by the vessel, an economizer compartment 64 enclosing a portion of the tubes 38 and dividing the vapour generation chamber into a preheat section and an evaporator section, the economizer compartment being open at opposite ends to discharge preheated liquid into the evaporator section, means 54 for supplying the compartment 64 with vaporizable liquid, and means for directing the flow of liquid through said compartment in separate streams in heat-exchange contact with the tubes 38 to respective ones of the open ends of the compartment. The tubes 38 communicate with inlet and outlet chambers, 44 and 46 respectively, for heating fluid. A baffle 24 surrounds the tubes 38 and defines together with the vessel wall an annular downcomer passage 32 for the recirculation of liquid discharged from separators 62. The economizer compartment 64 is defined by a portion of the baffle 24 and a diametral plate 65 welded thereto, and is provided with a liquid-distribution plenum 68 which communicates with the compartment 64 by means of circumferentially-spaced openings 70. The liquid entering the compartment via the openings 70 splits into two streams, one flowing upwardly and the other downwardly, and flows over baffles 66. In an alternative embodiment, Fig. 3 (not shown), a baffle (182) partitions the compartment into two separate sections (180a, 180b), each section having a supply nozzle (154a, 154b) and control valve (188a, 188b).

PERSON & SON]. 18 Nov., 1966 [18 Nov., 1965; 20 July, 1966], Nos. 49058/65 and 32539/66. Headings G4F, G4N and G4Q. In a vehicle directional indicator circuit in which left and right flashing indicator lamps I are selectively energized via switch S<SP>1</SP> from a current source including power transistor T 3  which is cyclically switched by an astable multivibrator circuit including transistors T 1  and T 2 , the multivibrator circuit is switched on when current flows in the lamp circuit by the field of a coil L 3  operating reed switch S 2  and is maintained on by discharge of a capacitor C 3  through the coil during the "on" periods of the power transistor. A further coil L 1  connected in series with the lamp circuit generates a field which operates a magnetic switch S 1  in the circuit for tell-tale lamp M. The coil L 1  and switch S 1  are positioned such that with all the lamps associated with one direction operating the field is only just sufficient to operate the switch, thus with a defective indicator lamp the lamp M is not energized. A further coil L 2  wound coaxially with but in the opposite direction to coil L 1  is provided to compensate for the increased field generated in coil L 1  when trailer lamps t are connected in parallel with the vehicles lamps I.

Title: Stabilised electric transistor oscillators
Inventor: FROST IAN BARRY VAUGHAN
IPC: H03B5/36
Filed: 1957-10-18
Abstract: 811,095. Transistor oscillators. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1957, No. 32583/57. Class 40 (6). In a, transistor oscillator, amplitude stabilization is effected by means of a " directlyheated " thermistor 16 arranged effectively in parallel with the output of the oscillator and a " block " thermistor 19 arranged in series with a feedback path interconnecting the collector and emitter circuits of the transistor. In the circuit shown comprising a parallel-tuned circuit 10, 12 forming part of the load in the collector circuit of the transistor and a piezoelectric crystal 21 connected in series in the feedback path, the crystal and tuned circuit being resonant at the same frequency, the " directly-heated " thermistor 16, whose resistance depends on the current flowing through it as well as on the ambient temperature, operates to maintain the output of the oscillator constant for a constant ambient temperature. However, the thermistor will not be able to correct for output variations caused by a change in ambient temperature: to correct for these the " block " thermistor 19, whose resistance is substantially independent of current flow through it, is provided so that when, for example, the temperature rises and thermistor 16 tends to stabilize the output at a lower level, the resistance of thermistor 19 falls to increase the positive feedback and hence the output level. A resistance 23 is arranged in parallel with thermistor 19 to match its temperature characteristics with those of thermistor 16. The Specification states that the piezo-electric crystal 21 may be replaced by a conventional series-resonant circuit or by a resistor in which case the circuit 10, 12 would be the sole frequency-determining circuit.

[Classes 7 (ii) and 7 (iii)] In a two - stroke engine cylinder, a ring of tangential piston-controlled inlet ports 1 are arranged above a ring of exhaust ports 2, the scavenging-air being thus caused to follow a helical path up the cylinder bore and to expel the exhaust gas down the cylinder axis. The inlet ports, which are formed as nozzles, are shut off by mechanically or automatically operated valves 5 until the pressure in the cylinder is reduced to that of the scavenging-charge. The cylinder head is formed as shown to facilitate the reversal of flow, fuel issuing radially from an axiallyarranged injection device.
