Title: Improvements in and relating to apparatus for moulding plastic substances
IPC: A21C7/01
Filed: 1927-12-19
Abstract: 291,692. Cowell, H. A. Dec. 19, 1927. Rolling-machines.-In apparatus for moulding doagh in which one or more carrying-belts run between upper and lower fixed surfaces or tables, the acting surface of the upper table is finely grooved or roughened. In the illustrated form, two superposed tables are mounted ad-justably upon screwed standards A. The lower table B is concave in cross section and supports a continuously-running belt M, while the upper one C is roughened slightly and preferably also corrugated on its under surface. The upper table is curved or flat in cross section according to the particular shape of loaf to be produced, and both tables are bevelled to a fine edge at the exit end to prevent deformation during delivery. A recess K at the entering end of the top table allows the dough to be fed to the centre of the belt. The upper table is spring-mounted at F so that it can yield upwards and set itself so as to maintain a constant compression upon doughs of varying stiffness.

Title: Improvements in or relating to ornamental sheeting
IPC: B29C59/04
Filed: 1965-08-11
Abstract: 1,128,722. Ornamental sheet; embossing; printing processes. E. A. MAGID. 11 Aug., 1965 [11 Aug., 1964], No. 34345/65. Headings B6C, B6G and B6J. [Also in Division B5] Ornamental sheeting in which the appearance of valley printing is simulated comprises a multi-ply web of material, at least the outer ply of which is light-permeable, said outer ply having portions of its normally exposed side depressed to emboss corresponding portions of its normally concealed side which confronts a backing ply to which it is bonded, and a decorative coating on the embossed portions which is visible through the outer ply from the exposed side thereof. At least the light-permeable layer may be of plastics material. In another embodiment, ornamental plastics sheeting comprises a light-permeable thermoplastic preprinted sheet, having portions of its normally exposed side depressed in an ornamental pattern to emboss corresponding portions of its normally concealed side which bears the printing, and a decorative coating on the embossed portions which is at least partially visible through the sheet from the exposed side to provide a protected printing effect. In Fig. 1, a web of light-permeable thermoplastic material 11 passes over heating rollers 12, 13 and then between the nip of tangential rollers 15 and 16, the former being a relatively hard, engraved steel roller and the latter being of rubber. The raised portions in the engraved roller form depressions on one side of the sheet which can be considered as embossing on the other side. These embossed portions are then coated with ink or adhesive by transfer roller 24. A web of backing sheet material 31 passes through a series of heating rollers and then into the nip between engraved roller 15 and another back-up roller 42 together with the web 20 to form laminate 45. An intermediate sheet such as netting, fabric, foam or lace may be interposed between the backing sheet and outer ply. The backing layer may be impressed into conforming relation with the embossed outer layer, or may be flat and secured only to the depressions of the outer layer leaving spaces occupied by atmospheric air between the backing sheet and outer layer affording a cushioning effect.

Title: Improvements relating to electron discharge apparatus
IPC: H01J1/32
Filed: 1928-11-22
Abstract: 302,307. British Thomson-Houston Co., Ltd., (Assignees of Thompson, H. C.). Dec. 14, 1927, [Convention date]. Vacuum tubes. - An electron discharge device comprises an electronemitting cathode and at least two other electrodes one of which is provided with a coating of a compound of a metal having alkaline properties, e.g. borates of potassium, lithium, sodium, barium, and magnesium, and oxides of barium, strontium, and calcium, to increase its efficiency as an emitter of impact electrons. A bead of the compound may be formed on a grid support and evaporated off into a plate by electron bombardment of the grid, or the compound may be mixed with a thin varnish and applied to the electrode and heated during evacuation of the device. If a coating of barium oxide is required the peroxide may be applied and converted by heat. The impact emission is improved by supplying to the space adjacent the coated surface a metal vapour having alkaline properties, e.g. magnesium or calcium. This may be done by applying a quantity 9 of metal in paste form to a grid support and heating during evacuation. The device shown comprises a filament cathode 1, surrounded by a control grid 2., which is surrounded in turn by a screening grid 3, an anode 4, and another screening grid 5, the grids 3, 5 being electrically connected together. The screening grids being operated at a fixed positive potential absorb a part of the electron stream that should proceed to the anode, but the coating causes them to yield an equal number of secondary electrons. The coatings may be used in negative-resistance devices such as described in Specifications 15555/15 and 150,359.

Title: Device for controlling the flow of a fluid by means of an auxiliary flow
Inventor: GELIN PAUL
IPC: F02K1/28
Filed: 1953-12-10
Abstract: 749,560. Jet-propelled aircraft. SOC. NATIONALS D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 10, 1953 [Dec. 12, 1952], No. 34439/53. Class 4. [Also in Group XXVI] The jet of a jet-propulsion unit is controlled by means of auxiliary gaseous jets formed by auxiliary nozzles opening transversely into the main jet and located at the periphery of the propulsive nozzle in a transverse plane thereof, the auxiliary nozzles extending along a small fraction of the length of the said periphery, and means being provided for allowing ambient air to enter a zone adjacent to and downstream of said auxiliary nozzles. As shown in Fig. 1 the discharge nozzle of a reaction propulsion unit is fitted with two tubes 5, 5<SP>1</SP>, diametrically opposed, the flow therethrough of fluid from a source at a suitable pressure being controlled by valves 6, 6<SP>1</SP>. The source may be a compressor or combustion chamber. The orifices 4, 4<SP>1</SP> are elongated in the sense perpendicular to the nozzle axis, and the nozzle is cut away downstream of the orifices to prevent the jet from re-adhering to the nozzle wall. In the modification of Fig. 4, a grid of blades 10 is placed downstream of the nozzle, outside of the normal jet stream, so that on injecting fluid through tubes 5, 5<SP>1</SP> the jet is constricted in the plane containing these tubes, and expands in the plane at right angles thereto, to be deflected rearwardly by the grid. In this embodiment holes 12a are made to fill the wake behind the injected fluid. In Fig. 7, a part cylindrical member 18 is slidable by a hydraulic servomotor operated by the compressor controlled by valve 23, to cover grid 10 internally when the jet is uninterrupted, and to expose the grid when fluid is injected into the main stream. One only of valves 6, 6<SP>1</SP> may be operated to give the jet a transverse component, and a plurality of pairs of tubes 5, 5<SP>1</SP> employed, so that conventional aircraft control may be dispensed with, especially at low speeds. Specifications 691,302, 691,948 and 696,088 are referred to.

Title: Improvements in or relating to electronic switching means
IPC: H03K17/54
Filed: 1954-11-29
Abstract: 783,895. Electric analogie calculating apparatus. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Nov. 29,1954 [Nov. 28, 2953; Nov. 28, 1953], No. 34588/54. Class 37. [Also in Group XL (c)] Fig. 2 shows a switching circuit in which a signal E is applied to the input 1 of a resistive attenuator 3, 14, 4 and to a negative feedback amplifier 10, 11. The diodes 6, 16 may have their cathodes switched to either a bias voltage U2 when both are non-conducting or to voltages U1 and V1respectively when both conduct. As will be seen from Fig. 3 where the characteristics of the diodes 6 and 16 are shown respectively by curves d1 and d2, if the input voltage E has a variation between Em and EM then when diode 6 conducts an undesired residual voltage will appear at point 5 which varies over a range of #U. This residual voltage is attenuated through resistor 14 and appears at point 15 as a residual voltage #V, which is of a sufficiently reduced value that it may be cancelled out by a compensating voltage of mean value #V and of opposite polarity introduced into the circuit. Fig. 7 shows an analogue multiplier comprising two electronic switches of the type shown in Fig. 2, the amplifiers 10<SP>1</SP>, 10<SP>2</SP> having either capacitive negative feedback so that they function to give an output proportional to the integral of the input voltage or resistive feedback. One of the variable voltages X to be multiplied is applied at input 51, a constant reference voltage - E o  is applied at 58 and a reference voltage 2E o  at input 1<SP>1</SP> the three arms 50, 59 and 31, 141, 41 being of equal impedance. The input terminals 52, 54, 56, 1<SP>2</SP> and 1<SP>3</SP> of the second resistive network have applied to them the voltages - E o , - K1.X, - ¢Y, 2E o  and the second variable voltage Y to be multiplied respectively. Two stable-state trigger circuit 25 is switched by the output of amplifier 101 and itself switches diodes 6<SP>1</SP>, 6<SP>2</SP> between their conductive and non-conductive states via cathodefollower stage 21, so that the voltage at point 21 switches from a value X + E o  to a second value X - E o  repeatedly. The input 2<SP>2</SP> to amplifier 10<SP>2</SP> is switched from a value 2E 0   Y to O. It is shown that the voltage at the output 12<SP>2</SP> of amplifier 10<SP>2</SP> is proportional to the product of the two variables X and Y. As will be seen, the corresponding voltages for balancing out the residual signals at points 15<SP>1</SP> and 15<SP>2</SP> are fed to the input of the amplifiers 101 and 102 respectively.

Filed: 1932-12-07
Abstract: 398,065. Inductance and capacitance measurements. ANDERSEN, J. U. F., 33, Vestergade, Copenhagen. Dec. 7, 1932, No. 34739. [Class 37.] Apparatus for controlling or indicating the level of material in a container comprises a condenser, the capacity of which is caused to vary with changes in the level of the material, and which is so connected through the medium of a thermionic valve with electrically controlled indicating or control means that variations in the capacity of the condenser cause corresponding variations in the indicating or control means. Two condenser plates 3 are supported from insulators 2 in the top of a container 1 and are connected between the secondary winding of a transformer 10 and the grid 6 of a thermionic valve 4, a grid leak 9 being connected between the grid 6 and cathode 7. In circuit with the anode.5 is the winding 12 of a relay arranged to control an indicator or valve. Increase in the capacity of the condenser due to rise in the level of the material between the plates 3 causes a decrease of the anode current, eventually causing the contact 14 of the relay to open. If the material in the container is a conducting liquid, the surface of the liquid may form one plate of the condenser, the other plate being arranged above the surface of the liquid and parallel thereto. If the apparatus shown is employed with conducting material, the plates 3 are insulated. In a modification, the condenser plates are omitted and a variable inductance is arranged to approach or recede from another coil as the level in the container rises.

Title: Improvements in or relating to measuring devices, dispensers and the like
Inventor: FROST JAMES
IPC: B65B1/36
Filed: 1958-10-30
Abstract: 942,861. Delivering measured quantities of liquid and other flowable materials; filling containers. PICKERING & WEST Ltd. Jan. 8, 1960 [Oct. 30, 1958], No. 34778/58. Headings B8N and B8T. In a machine for feeding solids, liquids, or semi-solids such as fruit, into containers, a dispenser comprises a measuring chamber 26 inside a cylindrical head 20 which is reciprocated through the bottom of a supply reservoir from which material to be supplied enters the chamber when its top is below the level of the material, the chamber having a flap closure 28a in its base which is opened to discharge the material when the top of the chamber is raised above the level of the material in the reservoir. To remove excess material from the top of the chamber as it is propelled above the level of the material in the reservoir, two sets of oppositely placed jets 57a, 57b are fed with compressed air to produce a vortex in the neck of the container which expels the excess back into the reservoir. Wipers may be employed to move across the top of the chamber. The chamber 26 is defined by a flat helix 30 telescopic between a lower cylinder 21 on which the closure flap is mounted and the cylindrical head 20. Cylinder 21 slides within the head 20 to adjust the volume of the chamber 26. Such adjustment being effected by altering the spacing between carriage rails 73, 74, Fig. 5, engaging wheels 85 and reciprocating each dispenser of the circular array rotating in the filling machine. Cylinder 21 joins a lower cylinder 22 which slides in screen 23 into which the container to be filled is introduced from underneath. The closure flap 28a is opened automatically by a cam rail which engages and raises a wheel 47 and push rod 42a on the dispenser. The leading portion of this cam rail may have a normally deflected position and be placed in a position to engage the wheel 47 only if a linkage is displaced by the entry of a container into screen 23, see Figs. 6 and 7 (not shown). To accommodate the flap operating mechanism the chamber 26 is eccentrically disposed in the head 20 to be in register with the eccentrically disposed passageway provided by cylinder 21. To prevent the insinuation of material between the turns of the flat helix 30, compressed air is supplied to the space 60 between the head 20 and the helix. The vortex jets 57a, 57b and the space 60 may be connected to a water supply to clean the dispenser.
