Title: Improvements in and relating to machines for making concrete pipes by the centrifugal process
Inventor: STONE WALTER LOCKEY
IPC: B28B21/34
Filed: 1959-08-20
Abstract: 853,833. Centrifugal-moulding machines. HUME PIPE & CONCRETE CONSTRUCTION CO. Ltd. Aug. 20, 1959, No. 28465/59. Addition to 841,787. Class 87(2). The invention of the parent Specification, which is essentially a machine for manufacturing concrete pipes by centrifugal casting embodying a U-shaped frame, adapted to receive a mould, rotatable in bearings and embodying means for effecting longitudinal vibration, is modified by the frame being closed to form a cage for the mould and supported at both ends on wheels mounted on freely rotatable runner wheels or rollers. The frame is in the form of a cage comprising axial bars f secured to the end rings a and the mould m has end rings n n<SP>1</SP> which engage rings k k<SP>1</SP> respectively attached to an end ring a and to a thrust ring i, the connection between n<SP>1</SP> and k<SP>1</SP> being tapered. The thrust ring i<SP>1</SP> is slidable on the rods f and is urged towards the mould by springs j which bear against the ring i and against a ring g which is also slidable on the rods f but is held in a selected position by pins h. The cage is therefore adaptable to moulds of various lengths, and of various diameters by changing the rings k k<SP>1</SP>. The rings a rest on rollers b and rotation is applied to one of the rollers by a belt and pulley drive d, c. Vibration is caused by projections i<SP>1</SP> from the ring i striking a roller v. This roller is on the end of an arm t pivoted between its ends, at u, to a lever o and variable in position by a screw device u. Release of the mould is effected by pulling a handle x to the right, as in Fig. 1, whereupon a rack y is engaged by a pawl z and a cable r swings the lever o about, a pivot p in a direction to move the ring i, against the springs j, so as to free the ring k<SP>1</SP> from the end of the mould.

Title: Improvements in or relating to radio transmitting systems
IPC: H03B5/34
Filed: 1928-10-08
Abstract: 298,481. Westinghouse Electric & Manufacturing Co., (Assignees of Trouant, V. E.). Oct. 8, 1927, [Convention date]. Thermionic Modulating systems.-The frequency of the oscillations generated by a crystal-controlled or similar valve oscillator is modulated for the transmission of telephone or like alternating- current signals by means of a controllable impedance connected in shunt to the tuned plate circuit of the oscillating valve, the modulating-valve being connected across a part of said impedance. The invention is a development of that described in Specification 292,469. The grid circuit of the valve 1 includes a piezo-electric crystal 5 or other mechanical resonator for determining the mean frequency of the oscillations. The tuned plate circuit comprises a coil 11 and variable condenser 12, and the valve oscillates by virtue of the inter-electrode capacity coupling. A shunt across the tuned circuit comprises a coil 37 and a blocking-condenser 39, and a part of the coil 37 is included in the plate circuit of the modulating valves 30. As shown these comprise two parallel-connected valves with their grid circuit connected to the secondary coil of a transformer 33, the primary including a microphone 35, which may be at remote point. Signals thus vary the impedance of the shunt network, and so impose slight variations on the frequency of the generated oscillations. The system may be employed in picture transmission and television systems. The output from the tuned circuit 11, 12 may be taken by tappings to an harmonic producer 17, amplifiers 18, 20 and coupling 21 to an aerial 22. These are of usual type, except that the tuned inter-valve couplings may have their damping slightly increased. Other aerials may be energized at the fundamental or harmonic frequency by line wires 100. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the transmission of telegraph signals by a key-controlled resistance connected across part of the coil 37. The oscillator may be of the Hartley type instead of being crystal-controlled. This subject-matter does not appear in the Specification as accepted.

Abstract: 464,687. Filling milk bottles. DAIRY ACCESSORIES CO., Ltd., MARTIN, E. A., and CADMAN, E. A. Oct. 21, 1935, No. 28944. [Class 125 (ii)] In apparatus for filling milk bottles or like receptacles from a container having a valve opened by upward pressure by the. mouth of the receptacle which is lifted by a yoke adapted to embrace the neck or top portion thereof and bear upwardly against a rim at the mouth thereof, the yoke comprises two side ledges over which the rim or tapering portion of the receptacle engages by lateral movement of the receptacle. A milk container A mounted on stand B has valves C comprising an inner shell c forming part of a fitting c<4> in the bottom of the container, and a valve c<1> mounted on a stem c<2> secured to a bridge c<3> also secured to fitting c'. An outer shell c<5> slides over shell c and is urged downwardly by spring c<6>. At its bottom is a seating to engage valve c<1>. A rubber seat around the bottom of shell c<5> receives the mouth of the bottle, which, moving upwardly, lifts the housing from the valve and permits milk to flow from the receptacle. A yoke D has a hole d large enough to receive the mouth of the bottle E, with ledges d<1> at its forward part to bear upwardly against the rim e of the bottle mouth. The yoke forms the forward part of a lever F pivoted at f to a transverse bar G. A rearward extension f of the lever is engaged by cam H on shaft h rotatable by handle h<1>. A pair of valves is provided, so set that when one yoke is lifted to open its valve the other is down. Thus a full bottle is removed and replaced by an empty one while another bottle is filling. In a modification the lever F has a forward extension fitted with a handle passing through a guide slot in a plate secured to the underside of the container A. A notch at the top of the slot permits the handle to be secured in the raised position, while a bottle is being filled. A modified form of yoke is open at one side to permit lateral insertion of the bottle and a plate is provided as a register against which the mouth of the bottle may be held to ensure the engagement of the rim e over the ledges d<1>. Instead of mounting the yokes on levers they may be guided for vertical movement and actuated by a cam. The Provisional Specification describes also a support for bottles not adapted for support by means of a yoke and a slightly modified form of lever for lifting the bottles against the valves.
