Title: Improvements in or relating to antifriction bearing surfaces
IPC: F16C33/28
Filed: 1928-10-08
Abstract: 298,485. Kozlowski, J. de. Oct. 8, 1927, [Convention date]. By solid lubricants.-A bearing lining has a reinforcement consisting of a number of superposed grates or grids of antifriction metal cast together, the spaces between the rods of the grates being filled in with antifriction metal of a different composition which forms a continuous mass in the whole element. As shown, a grid formed of parallel bars 1 has superposed on it a grid the bars of which form the sides 3 and diagonals 4 of a rectangle. The diagonal rods 4 are divided into two to form channels 5 for lubricant. Holes 6 containing graphite pass through the grates so as to leave a thin coating 7 of metal adjacent the closed end. When the second antifriction metal is cast round the grates, the graphite is closed in, and when the bearing surface is trued, the thickness 7 is removed to expose the graphite.

[Class 37.] A heating element for an electric heater more particularly applicable to tubular heaters in which the heating element or elements are arranged within a tubular casing, comprises spaced strips b of insulating material, such as mica, carried transversely between parallel longitudinal conductors a, the coiled heating wire k being supported in slots or notches d in these strips b, the slots d being closed by complementary strips f of insulating material co-operating with the supporting strips b. The supporting and retaining strips b, f are stamped from sheet mica and are threaded through holes c on to the stout copper conductors a, spacing being effected by insulating beads e also threaded on the conductors a. The resistance wire is laid into the notches d and the retaining strips f closed over so that the corresponding notches h, j in these strips coact with the resistance wire and one of the conductors a. End pressure, preventing movement of the retaining strips, is applied by means of clamping blocks l slidable on the conductors a and each provided with two screws m of which one clamps the block to the conductor a and the other serves as a terminal connection to the resistance wire which may be divided into sections connected in series or parallel to the bus-bars a. When the element fits into a tubular casing n the insulating strips are made to fit easily into the casing and no further support is necessary. The retaining strips f may be slotted to fit both conductors a in which case they are fitted after assembly of the supporting strips and the resistance wire.

Title: Improvements in or relating to the manufacture of self-supporting flexible films
Inventor: FOX BERNARD VICTOR
IPC: B29C48/10
Filed: 1960-08-23
Abstract: <PICT:0920805/IV(a)/1> Self-supporting flexible film is produced by extruding a liquid film-forming material through a die having an annular orifice formed between two die lip members, continuously dividing the stream of film-forming material at one or more spaced points within or adjacent to the annular orifice to produce a longitudinally split tubular stream of film-forming material while rotating or reciprocating at least one of the die lip members about its longitudinal axis relative to the point or points of division of the stream and converting the longitudinally split tubular stream of film-forming material into selfsupporting film. A preferred apparatus for producing the film comprises a die 1, mounted by bearings 2 in a housing 3, the die being capable of rotation by an electric motor 4 through a gear ring 5.  The die 1 has an annular orifice 6 formed between an outer lip member 7 and an inner lip member 8.  A passage 12 of annular cross-section is formed between the member 8 and a body member 9 which tapers upwardly to meet a feed channel 13.  A flange 10 is drilled with holes 15 to provide communication between the orifice 6 and the feed channel 13 which is connected to a feed pipe 14 through a rotary union 16.  Fingers 17 mounted at diametrically opposite points on the housing 3 are of such a size that they slide freely in the mouth of the orifice 6 when die 1 is rotated.  The process may be used for the manufacture of films of regenerated cellulose, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cellulose acetate, polyacrylonitrile, vinyl resins, casein, alginates, polyethylene, polypropylene, polyamides and polyesters. Reference has been directed by the Comptroller to Specification 744,977.

Filed: 1939-11-01
Abstract: 533,394. Gas turbines. MASCHINENFABRIK OERLIKON. Nov. 1, 1939, No. 29162. Convention date, Nov. 7, 1938. Drawings to Specification. [Class 110 (iii)] In a gas turbine installation, in which gases are heated at constant volume, the heating is arranged to produce a temperature stratification of the gases in the containing chambers and the cooler gases are expanded in the turbine. The residual gases in the chambers, being the gases which were initially at the highest temperatures, are subsequently expelled by a pipe byepassing the turbine The temperature stratification may be secured by differential heating of the gases and the last gas to enter the chamber may be heated most. If the gases are uniformly heated, the temperature of the gas the first to be heated is raised by adiabatic compression of gas due to the heating of the following gas. In this case, the last gas to enter the chamber is the coolest and the discharge to the turbine is in contrary direction to the entry of the heated gases. The operation of the process is described, inter alia, in connection with a plant similar in arrangement to that described in Specification 530,336.

Title: Improvements in or relating to Control Apparatus
Inventor: GRIFFITHS PETER THOMAS
IPC: G05D23/24
Filed: 1966-03-16
Abstract: 1,169,212. Control systems for heating resistors. SATCHWELL CONTROLS Ltd. 6 March, 1967 [16 March, 1966; 30 June, 1966]. Nos. 11573/66 and 29435/66. Heading H2H. [Also in Divisions G3 and H3] Apparatus for controlling a physical parameter comprises an electronic switch controlled by a two state circuit having an astable condition, the electronic switch being arranged to be conductive in only one of the two states thereof. The parameter may be temperature and the control may be automatic or manual. In an automatic temperature control system a thermistor 25 is situated to sense the temperature being controlled the value of which is settable by a potentiometer 29, which together with the thermistor 25 and other resistors forms a bridge circuit having a transistor 33 connected across its output diagonal. The transistor 33 controls the state of a two state trigger circuit which includes transistors 37, 39. When transistor 33 is turned off transistor 39 is continuously conductive and transistor 37 is turned off. The voltage developed across resistor 44. when transistor 39 is conductive is used to render a thyristor 56 conductive so as to provide a signal causing a bi-directional controlled rectifier 49 to become conductive thereby allowing current to pass through the heating coil 50. When the condition of the transistor 33 is fully conductive the transistor 39 is turned off and the transistor 37 continuously turned on, no current then passing through the heating resistor 50. When however, the temperature is such that the condition of the thermistor 25 is such as to cause partial conduction only of the transistor 33 the two state circuit is controlled to function in an astable state so that the transistors 37, 39 conduct alternately with a mark-space ratio determined by the condition of the transistor 33. The alternate conduction of transistors 37, 39 is caused by the charging and discharging of a capacitor 41 and a resistor 42. In a second embodiment the element controlling the flow of current through the heating resistor 50 may be a thyristor diagonally connected across a diode bridge. In further embodiments (Figs. 5, 6, not shown) the bridge circuit including transistor 33 is replaced by a variable resistor thus providing a manually controlled apparatus. The controlled apparatus may be a cooking utensil or an oven and the temperature sensing thermistor may be placed adjacent the cooking utensil inside the utensil and in the case of an oven inside the oven. The apparatus may also be arranged to control a refrigeration plant.
