Filed: 1937-11-30
Abstract: 500,899. Moulding pipes &c. by centrifugal machines. PORTER, W. A, Nov. 30, 1937. No. 33062. [Class 37 (ii)] Pipes &c. are moulded centrifugally bv feeding relatively dry cementitious material into a horizontal mould rotating about its axis, reciprocating the mould in a horizontal plane transversely to the axis, each reciprocation being terminated suddenly to jolt the mould, and applying a positive radial pressure to the interior surface of the material. A carriage, Fig. 1, comprising a central section 3 and end girders 4 is mounted to reciprocate on rollers 5 on the bed frame of the machine. Wheels 7 on transverse shafts 6<1> are adapted to support' a mould 11, one shaft being driven by. a belt 23 from a motor 22. A tie-rod 16 connected to the girders 4 passes through an upright 16<3> on the bed frame and carries adjustable lock nuts 161, a spring being provided between the nuts 16<1> and the upright 16<3>. A slide block 17 on the bed frame carries a cam cylinder 14 driven by a belt 24a which engages a roller 25 on the carriage to reciprocate it against the action of the spring. A wedge block 19, Fig. 4, operated by a hand screw 21 adjusts the position of the block. 17 relative to the upright 16<3>. A tie-rod 15<1> on the other end of the carriage carries an adjustable buffer 15a which contacts with a fixed block 15c to jolt the carriage at the end of its reciprocation. Rollers are provided on the fixed uprights to guide the girders 4. A roller 33 disposed in the interior of the mould 11 is supported in bearings 34 which may either grip the roller or leave it free to rotate in contact with the material. The bearings 34 are vertically adjustable by hand screws 38 to adjust the pressure on the roller. In a modification, one set of jolting mechanism is disposed centrally and two moulds may be mounted on one carriage. The jolting cam is mounted on the carriage and contacts with a roller carried by two shafts connected te a cross-bar 31, Fig. 11. A spring is provided between the roller and a cross-bar 26 .on the carriage. The cross-bar 26 also carries a stud 29a which contacts with a shaft 29, adjustable in the bar 31, to produce the jolting. In this modification, the adjustments for the rollers 33 may be geared together to operate in unison. In operation, the material is fed into the slowly rotating mould,. the roller 33 being fixed to act as a screeding bar. The speed of the mould is then increased and the jolting is started, the roller 33 being released. The mould may finally be rotated at an increased speed while the inner surface is trowelled. The roller 33 may be rotated by power if desired.

IPC: C21D9/52
Filed: 1967-07-21
Abstract: 1,173,037. Cooling metal rod. TEMPLE BOROUGH ROLLING MILLS Ltd. and BRITISH ROPES Ltd. July 16, 1968 [July 21, 1967], No.33712/67. Headings C7A and C7N. Steel rod from a rolling mill is, without the positive application of intermediate cooling, formed into non-concentric overlapping rings on a conveyer, and is then cooled forcibly by the application of a coolant which is generally air but may be another gas or a liquid at an average rate of at least 700 C. per minute through the range 750C. to 500C., but not so rapidly that bainite is formed. The rate of cooling through the range in which ferrite or cementite is formed is preferably greater than that through the range in which pearlite is formed and may be at least 1000C. per minute. Cooling may be effected by a series of fans, the first of which creates a greater flow of air than do subsequent ones. As shown in Fig. 3, rod leaving the final stand 1 of the mill passes without positive cooling to reeler 4, which causes it to fall in the form of overlapping rings 7 on to conveyer 6, by means of which it is carried through chamber 9 to cooler 20. The conveyer is preferably a roller conveyer, the rollers being tapered to effect relative movement between them and the rings. Chamber 9 is divided by partitions 19 into four sections, each of which has its own fan.

Title: Arrangement for connection of at least two conductors
IPC: H03K17/70
Filed: 1965-08-06
Abstract: 1,120,434. Semi-conductor gating circuits; telephone exchanges. TELEFONAKTIEBOLAGET L.M. ERICSSON. 6 Aug., 1965 [7 Aug., 1964], No. 33892/65. Headings H3T and H4K. A switching circuit comprises a memory device M connecting the two lines 2, 3 and connected at each side to a pulse source Ex, Ey through a respective switching device 4, 5, one at least of the switching devices being connected to a further voltage source E. The memory device is of the type which is set to a high or low resistance state depending upon whether a setting current decays rapidly or slowly, for example, as described in Specification, by restoring to a low resistance crystalline or high resistance amorphous state depending upon whether the setting current decays rapidly or slowly. The switching devices are of the type which break down when the applied voltage exceeds a threshold value and restore when the current is below a minimum sustaining value. To connect lines 2 and 3 pulses are applied at Ex and Ey and relay contact 12 is made. The resulting voltage exceeds the combined threshold of the memory and switching devices 1, 4 and 5 which therefore become highly conducting. The relay contact is then opened allowing a slow decay of voltage across a capacitor thus setting the memory device to its low resistance state and also eventually causing the switching devices to extinguish. The connection between 1 and 2 may be broken by applying pulses Ex and Ey alone. The combined voltage exceeds the breakdown voltage of the switching devices and the abrupt trailing edge re-sets the memory to its high voltage state and extinguishes the switching devices. In Fig. 7 a twowire line X, X<SP>1</SP> is connectable to a two-wire line Y, Y<SP>1</SP> through memory devices M1 and M1<SP>1</SP>. Single sources of pulses Ex and Ey supply the pair of circuits and a single additional voltage source E is connected in series with one arm of the circuit. A coordinate matrix switch may be formed from an array of circuits of Fig. 3 (Fig. 6, not shown), wires such as 2 forming the row wires and 3 the column wires with a memory 1 being provided at each crossing point. Individual pulse sources Ex and Ey are provided for each memory element but a common E source 11, 12 is used. An array of circuits such as 12 may be used to form a coordinate matrix for connecting two wire lines in a similar manner (Fig. 8, not shown).
