Title: An improvement in or relating to hobbing machines
Inventor: LEE BRIAN
IPC: B23F5/22
Filed: 1964-02-07
Abstract: 1,030,532. Gear-cutting. CHURCHILL GEAR MACHINES Ltd. March 3, 1965 [Feb. 7, 1964], No. 5222/64. Heading B3K. A gear hobbing machine for spur gears or worm wheels comprises an hydraulic pump which can either supply a motor 22 driving the hob and the work or a motor 33 for a rapid return of the hob-slide, and a pump to supply a third motor 40 for a slow feed of the slide. The pumps are driven by a common electric motor. The cutter head 105 can be fed to a depth gauged by a stop 107, which acts jointly with a switch 108 on the head engaging a dog in the bed. A further dog 111 actuates a switch 110 before full depth is reached and a dog 113 actuates a switch 112 when the head is moved away. The manually controlled variable-speed motor 22 drives the hob through gears 133, 137, 143 and 145 and the work through differential gear 147, gears 150, index change gears 155 and worm gearing 161. The reversible motor 33 drives a screw 116 through a shaft 162, worm gearing 163, a sleeve 165, a dog-clutch 166 and a spindle 167. A tangential-feed screw 123 is rotated from the sleeve 165 by gears 168, 169, 170, a dog clutch 171, worm gearing 173, a sleeve 175 and gears 176. For hobbing helical gears, the rotation of the work is modified by a drive from the shaft 162 through bevel gears 179, change gears 182 and the differential 147. The reversible motor 40 drives the shaft 162 through an electromagnetic clutch 189 for upward or downward feed of the hob-slide at a speed set by a hand valve. The pump supplying the motor 40 also supplies pistons for feeding the head 105 and for setting a hob shift device 130 before each new cycle. It also supplies a spring-loaded piston for clamping and unclamping the work and an axially-movable centre. When worm-wheels are to be cut, the clutch 166 is disengaged and the clutch 171 engaged. The hob-shift device 130 is disengaged and the hobslide moved tangentially of the workpiece. The tangential slide, however, may be omitted.

Title: Method of weft knitting tow
Inventor: PARR WILLIAM GEOFFREY
IPC: D04B1/00
Filed: 1965-02-06
Abstract: A web of filaments or fibres is fed towards a row of hooked knitting needles (1) Figs. 1 to 5, not shown and as the web is advanced the edge portion containing a bundle of filaments or fibres is partially separated from the remainder and taken by the advanced needles by being pushed down on to the needle shanks by sinkers (7) so as to be received in the hooks of the needles as they are withdrawn.  The needles can be devoid of means to close the books so that by their continuous reciprocation to receive the marginal portions of the advancing web the hooks become overloaded and eventually cast off a previous drawn bundle of filaments or fibres thereby forming a knitted mat of filamentary or fibrous material.  The web is fed in an undulating manner formed by feeding it over parallel slots (5) the front edge of which may be recessed to permit the separation of the marginal bundle of filaments or fibres by co-operating sinker action. Alternatively a separator (6), Fig. 1, not shown, may be provided which cooperates with the sinkers to divide the marginal portion. A claw arrangement (8) serves to advance the web.

[Also in Division G3] Thermal quantities are measured or regulated by an arrangement in which an ice-water mixture is contained between the walls of a double walled vessel surrounding the heat space for which the measurement is to be made, and in which at least a part of the mixture is introduced as a dielectric between the plates of a capacitor, the impedance of the capacitor, or an electrical quantity representing the impedance, being measured at a frequency of which the cycle period is shorter than the dielectric relaxation time of ice and longer than the dielectric relaxation time of water. Walls (2) (5), Fig. 1 (not shown) are insulated from one another and serve as the capacitor the output from which is applied to control a Peltier effect cooling element (1) through a regulator (6) and thus the temperature within the space (2). A double walled chamber which may be used as a calorimeter is described with reference to Fig. 2 (not shown), and an arrangement for measuring microwave energy in a waveguide (18) Fig. 3 (not shown) by measuring the heat developed in an absorber (11), comprises a double walled capacitor (12), (13) containing ice and water, the capacitance of which may be measured.

Patent GB-435258-A (GB)
Title: A method of preparing a food product
IPC: A23L29/281
Filed: 1934-02-17
Abstract: A gelatine food product is prepared by absorbing a palatable ingredient in a gelatine substance while the palatable ingredient is in the form of a foam.  The palatable ingredient may be a liquid flavour for example fruit juices or flavour concentrates, or an edible acid or sugar.  In practice, a solution is formed of the palatable ingredient, and a foam formed therein by passing an inert gaseous material such as air, carbon dioxide or nitrogen therethrough or by addition of a carbonate such as carbonate or bicarbonate of sodium or potassium to the solution which has been acidulated.  With fruit juices, the normal acidity may be relied on or citric, tartaric or malic acid or acid salts thereof may be added.  The gelatine substance is then mixed with the foam which keeps the particles thereof dispersed and prevents formation of lumps.  A relatively low temperature may be maintained during the foam-forming or mixing operation or both.  Thus heat of absorption may be removed by chilling to about 0-20 DEG  F. during the mixing. Excess moisture may be removed from the resultant product, for example, where a free-flowing granular product is desired, by passing a stream of relatively dry warm gas such as carbon dioxide or air, e.g. at 100 DEG  F., and having a relative humidity of 10 per cent, over the mass.  The product may be used in a gelatine dessert as the flavour and gelatine ingredients.

The pinions have left and right hand helical teeth respectively and are a running fit in their cavities. When torque is transmitted through the differential a frictional torque resistance is set up, at the outside diameter of the pinions, at the end thereof due to the axial thrust caused by the helical teeth and by a cocking couple due to the helix angle.

Title: Improvements in or relating to electro-optical image producing systems

Filed: 1929-02-18
Abstract: 306,542. Electrical Research Products, Inc., (Assignees of Manderfeld, E. C.). Feb. 24, 1928, [Convention date]. Television; synchronous movements.-In a television apparatus the current resulting from scanning the object is used to control the production of the image and to maintain the scanning apparatus in synchronism. The dimension, in the direction of the scanning lines, of the opening 11 in a screen 12, which defines the field of view, is made less than the distance between the centres of adjacent apertures 16 in a scanning-disc 14 (Fig. 2A, not shown), so that the light-beam is periodically reduced to a. low value at a rate determined bv the number of apertures multiplied by the speed of rotation of the disc. Alternatively this frequency component is introduced into the image current by making the width of the opening in the screen such that the last element of one line and the first element of the succeeding line are scanned simultaneously (Fig. 2B, not shown). At a receiver B the synchronizing component is selected from the image currents by a filter 33, 34 and impressed on the grid circuit of a thermionic valve 38. A generator 41, which is driven by the driving-motor 40 of a scanning-disc 26 and produces a current of the same frequency as the synchronizing-current, supplies current to the plate circuit of the valve. The amplitude of the plate current varies in accordance with the phasedifference between the locally generated current and the synchronizing current, and an electromotive force, which varies in accordance with the variations of the plate current, is impressed on a control winding 47 of the motor to maintain the scanning-discs 26, 14 in synchronism. According to modifications, a harmonic of the frequency determined by the number of apertures multiplied by the speed of rotation is used; the synchronizing-frequency energizes a motor at the receiver; or a mechanical damping-device 49, 50, 51, described in Specification 295,325, [Class 80 (ii), Gearing, Variable-speed &c.], between the motor and the scanning-disc is replaced by an electric damping-apparatus.
