Title: Improvements in and relating to the manufacture of soap bars or cakes having alphabetical or other designs therein
IPC: C11D13/18
Filed: 1942-07-01
Abstract: 567,773. Moulding soap. GARVEY, J., GARVEY, A., and GARVEY, H. M. July 1, 1942, No. 9077. [Class 91] [Also in Group V] A soap bar having a design therein is made by passing design soap 63, Fig. 11, through a die having means for forcing cover soap 62 into the re-entrant spaces thereof to form an intermediate bar and extruding a main body of cover soap 61 around the intermediate bar to form the complete bar. Fig. 1 shows apparatus comprising a die B fed with design soap through a pipe 36 and with cover soap through pipes 33a, the die being disposed within the converging mouth of a casing 15 containing a feed screw 21 for the main body of cover soap. Figs. 5 and 6 show the die B which comprises three separate thin-walled tubes 128, 125, 129 having the shape of the letters NEW. The tubes are mounted in a base 24 connected to the pipe 36, and are surrounded by a casing 30 mounted on a support 26 apertured at 28, the apertures communicating with the pipes 33a. The casing 30 forces cover soap into the re-entrant spaces 130-134. To ensure filling of the relatively inaccessible re-entrant spaces 23 of the letter E, a funnel 38 and partition 37 are provided. To fill the completely enclosed space above the horizontal bar of the letter A with cover soap, a separate supply pipe is connected to the space. As the complete bar emerges from the casing 15 it is cut into lengths by a cutter comprising a wire 46, Fig. 8, stretched diametrically across a circular rim 43 rotatably mounted within a circular frame 44 carried by the casing 15. The rim is rotated by means of a belt 47. The cut lengths drop on to a conveyer which feeds them to the top of a hopper where they descend to a rotary conveyer which presents them to two shaping dies. Fig. 9 illustrates a method of ensuring that a design, e.g. a word, will appear the same from both sides of the finished cake of soap. Two aligned casings 15 feed the soap with the designs reversed to two rotating cutter wires 46 which cut off lengths LL. These lengths fall on to a conveyer belt 50 which carries them to the shaping dies where the two reverse faces are pressed together, the exposed faces of the resulting cake bearing the proper design. The flow of soap through the dies may be made intermittent, so by using a cam-operated shutter, Fig. 10 (not shown), by this means may be produced a cake having a design extending inwardly only part way from one or both surfaces of the cake, or the cake may have the design hidden in the centre thereof.

Title: Improvements in and relating to a method or process for fixing turbine blades or thelike to discs or wheels
Inventor: BANKS JAMES WORLLEDGE
IPC: F01D5/30
Filed: 1947-04-10
Abstract: 643,212. Elastic-fluid turbines. BRUSH ELECTRICAL ENGINEERING CO., Ltd. April 10, 1947, No. 9498. [Class 110(iii)] [Also in Group XXII] A rotor for a turbine or the like comprises a disc, a peripheral ring on it having a peripheral groove in its interior and pierced with holes having the contour of turbine blades, and blades set in the holes. A groove 2, Fig. 5, having a width substantially equal to the width of the blades, is machined in a steel ring 1, and radial holes 3 are drilled. The order of these two steps may be reversed. The holes 3, the radius of which is equal to the radius of curvature of the rear convex face of the blades, are then enlarged to the sectional shape of the blades by broaching in three stages using a three-part broach as shown at a, b, c in Fig. 8. Each broach has a plain face corresponding to the said rear convex face. The turbine blades 6, Fig. 11, are then fitted into the holes 3 and welded to the ring 1 where they protrude into the groove 2. After heat treatment the ring is trued up and a rebate 11 is turned on each side face. The ring is then shrunk on to a disc 12 and secured thereto by welds 17. A peripheral channel 13, oblique holes 14 and, it may be, rebates 15, have previously been formed in the disc. Finally, the whole assembly is heat-treated and trued up. Side faces of the ring and disc may be machined with annular ribs and grooves to form part of a labyrinth packing. In operation, air or other cooling medium enters the hollow blades through the holes 14. The blades may be solid. Specifications 619,107, 625,693 and 643,259 are referred to.

Abstract: 1,062,861. Making plastics containers; seaming non-metallic sheet materials. BROWN MACHINE CO. March 6, 1964 [March 13, 1963], No. 9574/64. Headings B5D and B5K. [Also in Division B8] A method of making a container from plastics sheets comprises applying pressure to two mouldable sheets to form first and second container sections, severing the sections from the sheets and forming openings in one of the sections, and joining together the severed ends of the first and second sections. Conventional moulding heads extrude two sheets of thermoplastic material to supply vacuum forming machines which produce by differential pressure bottom sections 26 and top sections 27. The top sections proceed to a trimming machine where dies sever the sections from the sheet and punches form openings in the endwall of the sections, while a similar trimming severs the bottom sections 27 without punching holes. The top and bottom sections are then blown through tubes on to a conveyer 38, the top sections being inverted while in the tubes. From here the top and bottom sections pass via accumulator tables and single file conveyers 45, 46 to be " paired up " by a star-shaped wheel 50 and positioned on a rotatable carrier 55 of an assembly machine 49, the top sections 27 being supported on rotatable sleeves 65 and the bottom sections 26 being supported in fixed sleeves 84 such that the severed openings overlap. As the carrier 55 rotates the sleeves 65 are given a rotation by a belt 122 so that the top sections 27 are turned against the unrotated bottom sections 26, the heat developed by the friction serving to weld the two together. Once the sleeve 65 is given its rotation it is disconnected from the belt 122 so that when the top and bottom sections are properly joined the rotation can stop without damaging the weld. The completed container is blown on to the conveyer 46 for labelling, filling and cap application.

Abstract: 1,029,695. Raising steam in once-through boilers. A. S. GRIMES, R. S. HUNTER, and J. A. TILLINGHAST. March 6, 1964 [March 7, 1963], No. 9611/64. Heading F4A. In a forced flow, once through boiler means are provided for use during the starting operation for reducing the pressure of the working fluid to a value such that it may be discharged into the condenser of the turbine supplied by the boiler, the means consisting of at least one elongated tube wherein the pressure reduction is effected by friction of the fluid in the course of its flow therethrough. In the apparatus shown, a feed pump drawing water from a condenser 10 forces the water through an evaporating section 2, the steam flowing through a shut-off valve 4 to and through a superheater 3 whence it passes to a turbine 8 through a stop valve 7, the turbine exhausting on to the condenser. A pipe branches from the tube system between the evaporator outlet and the valve 4 and leads to a header 14 through a valve 15. From the header 14 a number of small bore tubes 20 each with a control valve 4 and a pipe 22 with a reducing valve 23 lead to a header 17 connected by a pipe having a valve 18 to a separator 19. Steam and water flow from the separator to the condenser through liner 24, 26 respectively. A similar pressure reduction apparatus 28 is provided branching from the tube system between the superheater outlet and the valve 7. At the initial phase of the start-up operation the valve 4 is closed and water pumped through the evaporator flows through one or more of the tubes 20 entering the separator at reduced pressure. The boiler is fired and when the flow at the branch point 16 consists essentially of steam the pressure reducing valve 23 is opened and one or more shut-off valves 20 closed. As the steam reaches its desired operating pressure valve 4 is opened and steam flows through the superheater and is reduced in pressure in the apparatus 28 which at this stage may be used alone or with the first pressure reducing apparatus. Finally, the valve 7 is opened and the valves 15, 15<SP>1</SP> closed and steam at working pressure and temperature passes to the turbine.

[Class 105] A magnet core member 3 on the track has polepieces 3<a> of a length to bridge simultaneously the poles 1<a>, 2<a> of two magnet cores 1, 2 on the locomotive one of which is energized by a generator d and the other of which has a winding connected to a relay r and according as the track core winding q is open or closed so the relay r is energized to one or other of two different extents at the passage of the train over the track core. Two series relays may be used separately responding to these currents. The circuit of the track core winding may be closed at a distant point to signal to the train and to receive a signal therefrom or may be controlled by a semaphore signal. The circuit may be controlled by a level crossing signal so that a notification is given that the crossing signal is in order or has failed. A level crossing signal released to go to the warning position by gravity and returned by a solenoid, both these actions being effected by ordinary track core windings energized from the train, is described. Fig. 4 shows an automatic system in which the circuit of the long polepiece track core 3 is opened and closed by core members 3<1>, 16 at the entrance and a core member 13 at the exit of a section which respectively effect the energization of windings 12, 14 to move the switch 11. The exit core 13 may also energize a bell winding 15 to notify a stopped following train that the section is again clear. The semaphore signal which is manually controlled opens the circuit of the core 3 when set at danger.
