Title: An electrical cooking device
IPC: A47J29/00
Filed: 1962-02-01
Abstract: 929,858. Egg-cookers. B. G. WEBB, and E. WEBB. Feb. 1, 1962, No. 3960/62. Class 28 (1). [Also in Group XI] Eggs are cooked in their shells, without surrounding them with water, by an electric heating element which extends most of the way round the egg, a holder positioning the egg with respect to the element. A cooker for six eggs, Figs. 2 and 3, has a metal ease formed in two halves, with four heating elements 14 in each half, shaped to form six approximately cylindrical containers 7 in each of which an egg can be centrally held by lugs 9 and members 10, air holes 11 and asbestos insulation 12 being provided above and below. Each element 14 consists of a resistance wire sandwiched in zig-zag formation between thermosetting resin and glass cloth laminate backed by asbestos sheet 13. In a modification (Fig. 6, not shown) the egg rests in a cavity formed, upon closure together of the two halves of the casing, by a pair of opposed hemispheroidal depressions formed in two sheets of good thermal transfer material. Alternatively, the heating elements may themselves be of hemispheroidal shape (Fig. 5, not shown). Reference is also made to: modified constructions of the heating element; the form of flat resistance elements to form oblong egg containers; the provision of separate elements and switches for each egg; the use of infra-red heaters; the provision of a thermostat, timer, and alarm device; the automatic breaking of the energizing circuit upon opening the cooker; and the incorporation of the egg cooker in a general purpose electric cooker.

Title: Improvements in or relating to automatic stop mechanisms for electrically operated record reproducers
IPC: G11B19/14
Filed: 1950-02-17
Abstract: 690,817. Gramophones; starting and stopping. HUTCHINGS, E. L. Feb. 19, 1951 [Feb. 17, 1950]. No. 4072/50. Class 40 (ii). As the tone-arm advances across a record, an arm W on the tone-arm pivot U gradually moves an arm B towards the turntable spindle T. An arm L is slidably. mounted on the arm B by screws K engaging slots O, and a spring N holds the arm L against a projection E on the arm B. A feeler P is so mounted on the arm L that it has a limited longitudinal movement. When the tonearm reaches the "run-off" groove the arm B and therefore the arm L and feeler P are moved quickly towards the spindle T, and a projection S on the spindle strikes the feeler and moves it laterally. This movement frees the arm L from the projection E and allows the spring N to pull the arm L back and thus disengage a switch element M on the arm L from a corresponding switch element J on the arm B, to stop the driving motor. The feeler P is automatically re-set during the opening of the switch by a stud Q on the base plate which engages a lip on the end of the feeler. The switch is re-set by moving the tone-arm to a position beyond its initial position which causes an arm X to engage a lip H on the arm B and move the arm back until. the projection E engages the arm L.

Abstract: 1,212,223. Heating, cooling or drying particulate material. ASHIZAWA IRON WORKS CO. Ltd. 26 Jan., 1968 [30 Jan., 1967], No. 4115/68. Headings F4G and F4U. In a method of heating, cooling or drying a particulate substance, the substance is whirled upwards over the internal wall of a cylindrical chamber and then dropped down the centre of the chamber in a continuous circulatory motion As illustrated, a measured quantity of the substance to be treated is introduced into the chamber 14 through a pipe 22 and is then whirled over the chamber wall 13 by compressed air issuing from nozzles 18. At the top of the chamber the air leaves through a filter 24 and the substance drops down the centre of the chamber for recirculation. The wall 13 is surrounded by a helical chamber 11 through which a heating or cooling medium may be circulated or in which an electric heating element may be located. When a substance is to be dried, the chamber 13 need not be utilized. To aid the treatment, the compressed air supply may be cooled, or heated and/or dehumidified. The chamber 14 has a conical bottom wall 15 leading to an outlet 21 provided with a valve 20 which is opened when the treatment is completed in order to release the substance from the chamber. The compressed air supply may be continued during release. In another embodiment, Figs. 3 and 4 (not shown), the conical bottom wall is replaced by a flat annular bottom wall through which the compressed air nozzles project. The central opening of the bottom wall is covered by a conical cap which directs falling substance towards the nozzles and which may be raised by an hydraulic or pneumatic apparatus in order to release the treated substance through the opening.

Filed: 1973-01-29
Abstract: 1413741 Ion beam apparatus CGR-MEV 29 Jan 1973 [31 Jan 1972] 4460/73 Heading H1D A beam of accelerated particles, e.g. deuterons from a cyclotron, translated in position by electromagnets E 1  or E 2  and deflected by an electromagnet E 3  is brought to a point focus on a target C by suitable selection of the parameters r, R, #, α, #, d, L or l. A triple focus, i.e. a momentum focus in two mutually perpendicular planes can be achieved. Mathematical relationships between the parameters which must be satisfied to achieve a print focus are set out, together with graphs (Fig. 3, not shown) from which suitable values can be selected. It is shown that an accurate point focus cannot be achieved with a parallel incident beam. A slightly convergent beam is necessary, and the form of the incident beam and the angle which it makes with the entry face A1 of the first electromagnet E1 may be adjusted by a known arrangement of three quadripolar lenses. The electromagnets each comprise two parallel plates separated by an air gap. A deuteron beam may be directed on to the target to produce a neutron beam.

Title: Improvements in or relating to variable frequency oscillators
Inventor: GRISDALE GEORGE LAMBERT
IPC: H03L7/185
Filed: 1961-02-07
Abstract: 973,421. Automatic frequency control systems. MARCONI CO. Ltd. Sept. 11, 1961 [Feb. 7, 1961], No. 4537/61. Addition to 839,656. Heading H3A.  A variable frequency channelized oscillator 10 is stabilized at intervals of 1 kc./s. by (1) beating it with a selected harmonic of a stable 1 mc./s. source in a mixer 9 to derive an output from filter 111 of frequency less than 1 mc./s., then (2) dividing the filter output by an integer factor selectable between 500 and 1000 in a frequency divider 13 to derive a 1 kc./s. output which is then compared in a phase discriminator 114 with a 1 kc./s. oscillation obtained by frequency division at 15 from the 1 mc./s. stable oscillator. The phase discriminator output then stabilizes the oscillator 10, through a reactance tube 16, at 1 kc./s. intervals according to the selected division factor. The frequency division range 500-1000 alone suffices (instead of 1-1000) provided a ganged control means GC is used to reverse by a changeover switch S the polarity of the output of the phase discriminator and, in the case of additional frequency fractions selected for the oscillator of less than ¢ mc./s., to conjointly select the next higher of the 1 mc./s. harmonics from which the channelized oscillator frequency is subtracted in the filter 111. The gang control GC may operate a pair of indicator scales, one indicating the actual range of frequency divided, the other the complement to 1 mc./s. of the actual range of frequencies divided to 1 kc./s.
