Abstract: 1521821 Continuously moulding foamed articles UPJOHN CO 5 Jan 1976 [28 Jan 1975] 00230/76 Heading B5A A double belt type moulding apparatus for the continuous production of tube parts of foamed material which are interconnected by relatively thin material providing one or more hinges, includes mould segments 3, 4 attached to conveying means 1 which are brought together to provide a mould cavity therebetween into which a foam material is fed. After foaming and removal of the moulding, the tube parts may be swung about their hinge or hinges to enclose a pipe and act as a heat insulator. The tube parts, Fig. 5, may comprise two different foamed layers 12a, 12b using apparatus in which the lower mould half conveyer belt is associated with two separate upper mould half conveyer belts allowing the second foam to be supplied to a larger mould cavity after the first foam has been delivered. The parting surfaces of the mould segments may be contoured to provide interengagement between the tube parts when they are swung together. Shell type inserts may be positioned in each tube part cavity and held therein during the foaming process.

A self-propelled welding device which can move along and inside a pipe and weld the pipe to another pipe has a transformer which can be moved close to the weld. The device which is supported at the left-hand end by spring- pressed idler wheels 13 and at the other by driven spring-pressed wheels 15 comprises a central tube 1 to the left-hand end of which is fixed a cylinder 2<SP>1</SP> containing a piston 3<SP>1</SP> carrying a frusto-conical wedge 4<SP>1</SP> for engagement with frusto-conical shoes 5<SP>1</SP> supported on the cylinder 2<SP>1</SP> by springs 17<SP>1</SP>. A further cylinder 2 carrying by springs 17 frusto-conical shoes 5<SP>1</SP> for engagement with a frusto-conical wedge 4 carried on a piston 3 within the cylinder, is arranged about the tube 1 and is secured to a cylinder 7 within which is a piston 8 fixed to the tube 1. Also secured to the cylinder 7 is a casing 9 which contains an electric motor 10, electromagnetic clutches 11, 11<SP>1</SP>, an oil pump 12 and a gear-box 14 through which the wheels 15 are driven. A transformer 6 carried on the cylinder 2<SP>1</SP> is connected to shoes 5 and 5<SP>1</SP> and a burr cutter 16 is provided on the cylinder 2. In operation with a supply cable connected to a plug 18 the device is placed in a pipe A and is propelled by wheels 15 into the tube until the shoes 5 are positioned adjacent the end of the pipe. The pump 12 is then driven to supply the cylinder 2 and move the piston 3 to clamp the shoes 5 against the end of pipe A. The supply cable is disconnected and a pipe B is moved over the device, the cable is reconnected and the oil pump is operated to move the piston 3<SP>1</SP> by the right thus causing shoes 5<SP>1</SP> to grip the pipe B. With current supplied from the transformer 6, oil is supplied to the cylinder 7 to move the pipe B towards and away from pipe A to make a flash butt weld between the pipes. The device is subsequently driven to the left and with shoes 5<SP>1</SP> clamped the cylinder 7 is supplied with oil to move the burr cutter 16 across the weld. The Provisional Specification describes a similar but slightly different machine.

Title: Improvements in or relating to parametric amplifiers
IPC: H03F7/04
Filed: 1966-01-05
Abstract: 1,114,093. Parametric amplifiers. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 5 Jan., 1966 [19 Jan., 1965], No. 477/66. Heading H3B. [Also in Division H1] In a variable capacitance semi-conductor diode parametric amplifier the diode is positioned so as to be subjected to substantially circularly polarized waves and is arranged to exhibit Helicon effect. A lamina of InSb on which is made a junction, Fig. 1 (not shown), is reverse biased and its housing 1 mounted inside waveguide 8 which connects the input signal source G(10) with a load C(11). The dimensions of the waveguide are such that propagation in the E mode is assured and the diode in its housing 1 is positioned with its plane parallel to the direction of wave propagation and perpendicular to the cross-sectional plane of the guide and in a region where the electric polarization of the wave is circular. If a magnetic field is now applied from magnet 9 as shown the semiconductor will exhibit Helicon effect and when an input electromagnetic wave of suitable polarization is propagated from the source G(10) the semi-conductor acts like a substantially perfect dielectric for the wave. The equivalent circuit of the arrangement includes two capacities in series, a variable capacity presented by the reverse biased junction and pumped by pump signal from Klystron K(12) via guide 13 and a fixed capacity due to the dielectric which the semi-conductor presents when exhibiting Helicon effect, thus preventing losses which would have occurred if the equivalent circuit had included a resistance. The Helicon effect also prevents passage of the high frequency back from the load C(11) to signal source G(10) since the direction of polarization of the forward going wave is reversed by the load and the diode acts as regards propagation in the reverse direction as an open circuit and no amplification takes place in the reverse direction. Isolation between pump circuit and load circuit is done by means of tuning stubs or screws 18.

Title: Improvements in or relating to animal feeding apparatus
IPC: A01K5/02
Filed: 1929-01-05
Abstract: 322,122. Oldman, H. W., and Briscoe, W. A. Jan. 5, 1929. Feeding-appliances for animals.-In feeding- apparatus for animals, of the type in which a limited supply of food to a trough is permitted by means controlled by a pivoted member or door operated by the animal's head, the operation of the door causes a discharge opening in the food hopper to be opened to allow some food to pass to the trough, further movement of the door causing the discharge opening to be closed so long as the animal's head: remains in position. The door C, which normally covers the trough B, is pivoted at C' and is connected at its inner end by a link E and universal joints E<1>, E<2> to a shutter D formed with opening D<2>which during the movement of the door C registers with an opening A<2> in the floor hopper A. The latter part of the upper movement of the door C carries the opening D<2> beyond the opening A<2>. While the openings are in register, a limited amount of food passes out of the hopper A, assisted by a stirrer H moving with the shutter, to the trough B. The fall of the door C on the withdrawal of the animal's head may cause a further quantity of food to pass to the, trough. The size of the opening D<2> may be adjustable.

Filed: 1976-01-07
Abstract: 1519401 Temperature control J M PALMIERI and A M ESPOSITO 7 Jan 1976 00506/76 Heading G3R A digital electronic thermostat compares binarycoded decimal representations of an actual and a desired temperature and furnishes an 'operate' signal when the temperature error has a given sense. A thermistor 20 controlling an oscillator 18 feeds a temperature-dependent frequency to two counters 24, 28 which respectively register the tens and units digits of the number of cycles of oscillation occurring in a time interval determined by a clock 34. The tens and units are compared, by devices 72 and 70, with values set by devices 62 and 54. With the switches 86 and 94 set as shown, an output is obtained at 110 of the sensed temperature is too  low. By reversing these switches, the output may be given if the sensed temperature is too high. Thus either heating or cooling may be controlled. Modifications, Figs. 2 and 3 (not shown), provide for a "dead zone" (errors of the relevant sense but less than a predetermined magnitude ignored) and for switching of the input from one to another of several temperature sensors (e.g. from a living-room to a bed-room at night).
