Title: Improvements relating to collapsible tubes for holding extrudable material
IPC: B65D35/28
Filed: 1952-05-09
Abstract: 723,810. Closing collapsible containers. BICKLE, H. M. Aug. 6, 1953 [May 9, 1952], No. 11868/52. Classes 66 and 94 (1). The lower end of a cylindrical collapsible tube filled with an extrudable material is closed by flattening the lower end portion so as to close the lower end and simultaneously shaping that end portion to have a rectangular cross-section increasing in width and decreasing in depth towards the lower end of the tube, the upper portion of the tube gradually changing from a circular cross-section to the rectangular crosssection. The tube may be shaped and closed by means of the apparatus shown in Fig. 10 comprising a die having a, tubular socket 10 from which extend axially opposed arms 11 outwardly curved to the contour of the narrow face of the tube. The die, containing the filled tube 12, is placed in a housing 14 having forming rollers 16 whose spindles are mounted in slots 15 and which are urged towards one another by spring arms 17. By moving the die with the tube axially as shown by the arrow, the rollers gradually flatten the sleeved tube and form the convexly curved wider faces while the arms 11 restrict lateral spread of the lower end portion of the tube and impart a concave curvature to the relatively narrow faces. In another embodiment the wider faces are shaped by jaws pivoted to the housing 14 and moved into operating position. by means of a lever and intermeshing toothed quadrants fixed to the jaws. In a further embodiment, Fig. 12, the wider faces are shaped by members 23 each pivotally secured at its upper end to one end of an arm 24 pivotally carried at its other end by a rotatable disc 25. At the remote ends the members 23 are urged towards each other by rods 26 mounted in slots 27 in a housing 28 and connected by springs 29. The slots are shaped to move the members 23, on rotating the disc 25 into the appropriate forming position. In another alternative embodiment the filled tube is embraced by pivoted jaws to form the narrow faces of the tube and two further opposed jaws are then moved towards each other to form the wider faces, the narrow jaws preventing lateral spread of the tube under the action of the wide jaws. The tube may be enclosed in a sleeve of cardboard or other sheet material having a substantial degree of rigidity and the tube and sleeve together are subjected to the simultaneous flattening and shaping operation.

Title: Process and apparatus for the moulding of concrete articles of all kinds
IPC: B28B13/02
Filed: 1930-04-15
Abstract: 352,968. Moulding pipes, hollowware, &c. by fluid pressure. RUML, B., 32, Pstrossova, Prague, and RUML, F., Plßtenice, both in Czecho-Slovakia. April 15, 1930, No. 11900. [Class 87 (ii).] In the process of moulding hollow articles by forcing concrete into the mould by air-pressure, a system of balancing valves is employed to maintain a standard pressure during the filling of the mould, means also being provided for working at different pressures at different stages of the process. Fig. 1 shows a compresser 13 charging a reservoir 11 which communicates with a holder 15 for fluid concrete connected to the mould 2. At the commencement of the operation the cocks 27, 20 are opened allowing fluid to pass partly along pipe 14 through the balancing valves 17, 17<1>, 17<11> which are set to reduce the pressure but mainly along pipe 25 through the valve 18 to set the concrete in the container 15 in motion. The valve 18 is set to a higher pressure than the valves 17, 17<1>, 17<11>. When the concrete is in motion the cock 20 is closed leaving the pipe 14 to carry the fluid at a lower pressure for completing the charging of the mould. The air passing through pipe 14 is maintained at a constant pressure by the valves 17, 17<1>, 17<11>. When the mould is charged the cock 21 is opened allowing fluid to pass the valve 19 at a much higher pressure to force the material against the walls of the mould. As applied to the moulding of pipes, the mould is made in three segments 1, 2, 3, Figs. 2 and 3, perforated at 10 for the passage of a heating medium. A metal pipe 6 forms a core and surplus liquid escapes through tapered holes 7 in the periphery kept free by means of hand-operated rakes or combs 24. The initiallyset moulded article is dried from the exterior inwards by supplying heating means to the perforations 10. Finally the core is heated and rotated. Reinforcement may be arranged helically within the mould, being threaded on concrete rings to space it from the walls of the mould.

Title: Improvements in variable speed gearing
IPC: F16H29/04
Filed: 1936-04-27
Abstract: 469,268. Variable - speed gearing. SEIDEL, R. April 27, 1936, No. 11926. Convention date, May 3, 1935. [Class 80 (ii)] A variable-speed gear comprises an adjustable eccentric 53 on a driving shaft 20 which oscillates a guide ring 60 and a number of levers 73 arranged in a circle around the axis of the gear, the amplitude of this oscillation depending upon the eccentricity of the eccentric 53. The oscillatory movement of the levers 73 is transmitted by shafts 72 to a set of pinions 83 through one-way clutches 78, 82, in one direction and to another set of pinions 84 through oppositely disposed one-way clutches in the other direction. The pinions 83 are geared directly to a pinion 13 on the driven shaft 4 and the reverse drive of the pinions 84, which all mesh with a loose pinion 15 on the shaft 4, is taken through idler pinions 88, 89 to the other set of pinions so that the oscillatory movement of the levers 73 is utilized in both directions. The eccentric 53 is adjusted by means of a shaft 36, gearing 35, 34, pinions 30, 26, and a pinion 25 which is threaded onto a stationary sleeve 7. Rotary movement of this pinion thus also produces axial movement which is transmitted to a rack 69 which, through a pinion 67 on a plate 50 secured to the driving shaft 20, actuates a rack 68 on the eccentric 53 which is radially displaced along suitable guides on the plate 50. The pinion 67 also actuates another rack 66 which displaces a disc 64 radially but in the opposite direction to the eccentric 53 automatically to balance the centrifugal forces.

Title: Control devices for ovens or burners
IPC: G04C23/16
Filed: 1963-03-26
Abstract: 986,942. Timing apparatus for controlling cooking. ROBERTSHAW CONTROLS CO. March 26, 1963 [April 12, 1962], No. 11957/63. Heading A4D. [Also in Division H2] A timer for a gas or electric oven institutes the cooking period as soon as it is set and, thereafter, reduces the oven temperature to keep the cooked food warm until it is required. The oven temperature is varied by a thermostatic control operated by temperature setting knob 50 on control shaft 51. The operation of a time setting knob 52 is linked with that of the temperature setting knob 50 so that the former is inoperable when an untimed cooking operation is taking place. To set the timer, the knob 50 must first be positioned at a temperature setting below the food warming temperature and, in such a position, pawl 115 can be moved into the patch of notch 82 by rod 118 or lever 108. Subsequent movement of the time setting knob 52 pivots the lever 108 and brings both pawls 114 and 115 into operating positions. Simultaneously, the drive to continuously running timer 42 is broken by displacement of pinion 98 against the force of tension spring 105. When the knob 52 has been turned through an angle corresponding to the desired cooking period, spring 105 re-establishes the drive between timer 42 and wheel 95. The latter is subsequently driven back by timer 42 to its original position in which the mutilated portion 97 is opposite pinion 98. Knob 50 drives only one, 85, of discs 78, 85 and 86 directly. The movement of shaft 51 is transmitted to disc 86 by pin 89 engaging slot 90 and to disc 78 through tension spring 91. At the food warming temperature setting, disc 78 is brought to rest by the engagement of notch 82 with pawl 115. Subsequent movement of knob 50 to higher temperature settings, together with discs 85 and 86, winds up spring 91. On release of knob 50, pawl 114 retains disc 86 against the torsion of spring 91. However, if the temperature setting is inadvertently adjusted beyond the intended value, a pawl-unlocking mechanism can be used to enable knob 50 to be rotated back again. The unlocking is produced by using the lost-motion between discs 85 and 86 to cause pawl 114 to ride up on teeth 88 out of engagement with teeth 87. As the cooking period ends and lever 108 falls back into notch 107 under spring 134, pawl 114 is retracted by means of pin 120. Discs 85 and 86 are thus released and rotate, together with shaft 51, under the action of spring 91 until rod 89 comes into contact with roller 83a. The temperature is accordingly adjusted to the food warming setting and roller 83a is retained in notch 133 of lever 125 until the action of lever 125 is overcome by turning knob 50 to the off position. The apparatus may be modified (Figs. 23-28, not shown) to allow variation or adjustment of the food warming temperature. Specification 938,800 is referred to.

Title: Improvements in or relating to devices embodying cavity resonators
IPC: H01P7/06
Filed: 1954-04-26
Abstract: 758,966. Cavity resonators. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 26, 1954 [April 29, 1953], No. 11988/54. Class 40 (8). [Also in Group XL (c)] An axially symmetrical cavity 1 resonating in a transverse-electric mode contains a discshaped or cylindrical ferromagnetic, e.g. ferrite, body 4 or 4<SP>1</SP> polarized by a solenoid 5. The cavity is excited to oscillate in the TE 111  mode by e.g. a loop 2. Owing to the presence of the ferrite body the cavity has two different resonance frequencies corresponding to the resonances of the two circularly polarized components of the transverse oscillation. By increasing the magnetic field the difference between the two resonance frequencies and hence the band-width of the cavity can be increased and the response curves shown in Fig. 4 are obtained. The magnetic field may be produced by a solenoid 5 or by a disc of permanently magnetized material, e.g. ferroxdure, adjacent the body 4. When the magnetic field is zero the response of the cavity corresponds to that of a simple tuned circuit. The cavity may be modified by combining the bodies 4 and 41 in such a manner that the curved sides and one end are lined with magnetic material. Specification 674,874 is referred to.
