Title: Improvements in or relating to the moulding of concrete products
IPC: B29C51/22
Filed: 1919-12-22
Abstract: 160,551. Hume, W. R. Dec. 22, 1919. Centrifugal machines; moulds; moulding pipes and tubes.-In a machine comprising a cylindrical or like casing formed of longitudinal sections with retaining-rings at either end resting on rollers, by frictional contact with which the casing is rotated, the cylindrical recesses 8<a> of the retaining rings 9, Fig. 3, are provided with flared mouths 8 to facilitate the assembling of the sections 6. The sections are bolted together by means of angle-irons 13, Fig. 4, and the casing is strengthened by an encircling frame formed of circumferential and longitudinal bars 14, 15. The bars 15 are provided with projections 16 which serve as trunnions so that the casing can be handled by a crane. Concrete from a mixer 25 is deposited in the rotating mould by an endlessband conveyer 23 running on a frame suspended on links 21, so that it can be moved in and out. A second conveyer may enter the other end of the mould casing. The rings 9 have flanges 18 of a depth corresponding to the thickness of the concrete. The depth of the flanges is increased by detachable rings 19. The mould is rotated slowly while the concrete is supplied, then more rapidly to expel the surplus water, after which the rings 19 are removed, the water run off, and the speed again increased for the purpose of finishing the interior surface. In forming cylindrical sections for wells, caissons, &c., arrangement may be made for exposing reinforcement attachment means, such as eyes or hooks, by which one section is connected to the next. As shown in Figs. 8 and 9 this is done by core-pieces 34 placed on either side of the eye 33 and held against the casing by a screw 35. Two-part cores may be similarly used to form apertures with stepped or rabbeted edges in the moulded article. Core-pieces to form recesses on the inner side of the concrete shell or tapered apertures may be fastened to bars inside the casing secured at their ends to the rings 9. When longitudinal sections are to be formed plates 26, Fig. 6, may be inserted to project inwardly at the longitudinal joints of the casing. To form longitudinal interlocking sections channel-shaped members 38, Fig. 11, may be detachably connected to the flanges of the retaining- rings 9. For moulding short cylinders the casing is divided by annular rings kept in position by contact with reinforcing members. To provide parts of wells or caissons with a reinforced penetrating edge, a bevelled metal band 29, Fig. 7, may be attached to the reinforcement 30, and the edge 31 of the concrete may be chamfered by means of a bevelled moulding surface attached to the flange of the retaining-ring 9. Reinforcing bars 41, Fig. 13, may be held in position by spring clips with ends 44 which contact with the inner surface of the mould casing. Specifications 21626/13 and 21627/13, [Class 99 (ii), Pipes, tubes, &c.], are referred to.

Title: Improvements in or connected with sound reproducing
IPC: G05B19/06
Filed: 1927-12-02
Abstract: 309,208. Wilson, S. K., and De Forest Phonofilms, Ltd. Dec. 2, 1927. Optical records and apparatus.-Sound photographically recorded on a strip is selectively reproduced or emitted in any desired locality and its volume or other characteristics varied by means controlled from the record which means may comprise notches or projections co-operating with electrical or mechanical devices. The reproduction may be effected in conjunction with a kinematograph and appear to issue from the audience or any desired position, for example the roof in the case of a scene depicting aeroplanes &c. In Fig. 1 the record film 1 is notched or cut away along the sides to control spring contacts 4 so as to actuate a relay 9 whereby the sound reproduced by a photo electric cell 11 and amplifier 10 is reproduced by speakers 7 and 8 or the speaker 6 as desired. The speakers may be disposed in any desired position in relation to the picture screen, and the film may have perforations instead of edge notches and move between clip contacts. In a modification the selection or control may be effected by markings 26, Fig. 9, on the strip record, for example at the opposite side of the pictures 24 from the sound record, and light is projected through such markings by a lamp 28, Fig. 8, on to a cell 30 controlling a relay 32 acting as in Fig. 1. The two lamps 28, 27 may be replaced by a single lamp and two refracting prisms which direct the light through slits on to the sound record and selecting markings respectively. Alternatively, the selecting means may operate to bring another sound record into operation, and may also control resistances to vary the volume or control different emission orifices from one reproducer.

Filed: 1935-11-25
Abstract: 466,491. Dispensing pastes. SHARP, P., and POTTER, W. G. Nov. 25, 1935, No. 32612. [Class 102 (i)] [Also in Group XVII] The contents of a collapsable tube are extracted by a suction pump and in addition the tube is subjected to a squeezing action. As shown in Fig. 3, the neck of the tube is inserted in a flexible sleeve 17 carried by a piston 14 which is movable in a cylinder 8. Side plates carried by the piston 14 are formed with racks 21, which are engaged by pinions 22 on a bifurcated operating lever 24 pivoted at 25. The suction stroke is effected by springs and fills the cylinder 8 through a flap valve 16. Depression of the piston by means of the lever 24 discharges the paste through a flap valve 10 and a spout 12. The upward stroke of the piston 14 forces the tube between rollers 32, 32<1> carried by a carriage 30, upward movement of which is prevented by means of pawls engaging side racks 28. In a modification, Fig. 10, a cylinder 68, provided with a valve 66 and a spout 67, moves on a fixed piston 63, provided with a valve 65.

Title: Improvements in frequency-dividing and like circuits
Inventor: ROZNER FELIX
IPC: H03K5/00
Filed: 1955-11-15
Abstract: 814,741. Multistable-state circuits employing thermionic valves and transistors. FERGUSON RADIO CORPORATION Ltd. Dec. 4, 1956 [Nov. 15, 1955], No. 32674/55. Class 40 (6). A multistable-state circuit designed to operaate as a pulse-frequency divider comprises two valves or transistors which are reciprocally coupled by direct-current connections from the anode or collector of each to the control grid or base of the other, there being further provided a capacitive connection between the cathodes or emitters and an input circuit for applying pulses in parallel to the two control grids or bases. In the circuit shown employing NPN type transistors, negative-going pulses, having a recurrence frequency within predetermined limits, are applied to the terminal T. Assuming a steady state has been reached the effect is to cut-off whichever transistor is conducting and cause the other to conduct; however, provided the pulserecurrence frequency exceeds a predetermined minimum the next pulse to be applied will not restore the original condition since, owing to the capacitor C3 interconnecting the emitter electrodes, a positive bias will remain upon the emitter of the non-conducting transistor. Thus it will not be until the capacitor C3 has sufficiently discharged and re-charged in the opposite direction that the circuit will again be capable of changing over on the application of a negative pulse to the terminal T, and consequently the number of output pulses derived from a suitable point, such as one collector electrode, will be a sub-multiple of the number of input pulses applied. A diode D3 in parallel with a variable resistor R7 is arranged in series with the capacitor C3; this permits the discharging and charging time-constants in the two directions to be different and hence permits adjustment of the division ratio and selection, if desired, of one having an odd value. It is stated that alternatively PNP junction type transistors or unipolar transistors may be used, while the circuit may be modified to use thermionic valves instead of transistors.
