Abstract: 783,271. Beverage preparing apparatus. STOTT & CO (ENGINEERS), Ltd., J. Dec. 23, 1954 [Dec. 24, 1953], No. 35849/53. Class 129. [Also in Groups XIII and XXIX] Beverage preparing apparatus comprises a boiler with cold and hot water inlet and outlet pipes 34A, 34D, one pipe jacketing the other, the hot water being pressure-fed from the boiler to a coffee percolator 62 from which the beverage is led to at least one transparent storage urn 77. The boiler consists of a cylindrical water container 42, whose lower part is formed with tubes 42B, mounted concentrically inside a container 40 within the bottom of which is a gas heater 50 and a combustion chamber from which heated gases pass round tubes 42B to the flue pipe 45. The gas for the heater is controlled automatically in response to the steam pressure in the upper part of container 42 (see Group XXIX), by a control device 8 which is operated by main and pilot hand levers 4, 3. The boiler has a safety valve 71 and a pressure gauge 6 and is fitted underneath a counter which supports a platform 28 and a column 26 to house flue pipe 45. Two or more urns 77 of heat-resisting glass fitted on rubber bases and surrounded by outer cylindrical bodies 84 are supported on platform 28, the junction 80 between each urn 77 and body 84 being sealed. Each urn is heated by steam from the boiler which enters the space between body 84 and urn 77 through pipe 91 controlled by valve 58, condensed water being drained by tube 93 through outlet 95. Each coffee infuser 62 comprises a cylindrical body 62A removably fitted between two circular covers 62E and 62D, sealing rings 62F being provided. Water is led through inlet valve 60 and a central opening in cover 62D on to a perforated plate 62G which sprays it on to coffee resting on a strainer 62C beneath which is a filter paper 62B resting on a perforated plate 62J. In operation, water is supplied from the mains through a regulator 10 and passes up through tube 34A to a valve 9 (see Group XXIX), controlled by a float in the boiler so that the level in the boiler is maintained constant. Boiling water from the boiler passes down through tube 34D and thence to the manually controlled inlet valve 60 of one of the infusers 62. Valve 98 directs the infused coffee to one of the urns 77 and has an outlet 101 through which the infuser may be emptied into a drip tray 28. Steam may be drawn off from the boiler by delivery tube 74 controlled by valve 5 to a swivel pipe 52 with one or more small bore holes at the end for use in heating small quantities of milk or the like quickly or heating tea or coffee pots. Boiling water may be drawn off from boiler 42 through tube 68 controlled by valve 7 and delivered through an anti-splash nozzle 70 (see Group XXIX). Valves 5, 7 and 60 are all constructed similarly.

Filed: 1920-12-21
Abstract: 176,551. Canda, F. M. Dec. 21, 1920. Rolling balls; axial rolling.-In an apparatus for making spherical or ellipsoidal balls, a bar of material is forced by a presser between grooved rolls rotating in the same direction. The apparatus is primarily intended for making wrought iron or steel balls for crusher mills &c., but is applicable also for making lead shrapnel balls or lead shot. A bar of material fed down a slide 10 is forced between grooved rolls 1, 2 by discs 12, the journals of which are carried by brackets secured to a bar 5. The discs 12 are narrower than the grooves in the rolls, and are preferably cylindrical with rounded edges. The bar 5 is fed forward and retracted by hydraulic cylinders 7, or otherwise. The balls do not pass completely between the rolls, and are discharged at the side at which they enter. The roll 1 may be of less diameter than the roll 2, in which case the path of the presser is oblique to the roll pass. In another modification the rolls are arranged side by side, and the balls are forced completely through the pass by a presser arranged above the rolls. In order to allow for irregularities in the stock, each presser disc 12, Fig. 10, may be journaled in a separate piece 14<a>, sliding in the cross-bar 5<a>, and acted on by a separate ram 17. In this and in other arrangements each disc 12 may be supported by side discs 16.

Title: Cycloconvertors
IPC: H02M5/27
Filed: 1972-07-12
Abstract: 1359048 Frequency changing DEFENCE SECRETARY OF STATE FOR 12 July 1972 [3 Aug 1971] 36403/71 Heading H2F A forced-commutation cycloconverter includes control apparatus for generating a regular stream of switching pulses for controlling the conduction of the main converter elements, a feedback circuit for deriving a control signal from selected harmonic components of the cycloconverter waveform and causing said control signal to be amplified or attenuated by a factor varying substantially in accordance with the instantaneous value of the rate of change of the fundamental component of the output waveform and a control circuit for causing the timing of individual switching pulses to be perturbed by amounts depending on the instantaneous values of the control signal. The feedback circuit thus has the effect of minimizing harmonic content and reducing the size of output filter necessary. As shown in Fig. 1, a P-phase input at frequency fg is fed into a forced commutation cycloconverter 4 utilizing gate-turn-off switches connected in inverse parallel. The gateturn-off switches are controlled by firing circuits 2 in dependence on a triangular signal of frequency P (fg+fo) where fo is the required output frequency. Selected harmonics are derived by a filter 6 and divided at 3 by a cosine wave formed by integrating at 7 the fundamental frequency from the cycloconverter 4. The output from divider 3 is used to modify the signals from the firing control circuit 2 so as to minimize harmonics in the output of the cycloconverter 4. Fig. 2 relates to a block diagram of the divider 3; the harmonics from block 6 are fed into the in-phase input of a differential amplifier the output of which is fed into one input of an analogue multiplier, the other input of which is received from a Miller integrator 7. The output of the multiplier is fed to the anti-phase input of the differential amplifier. Fig. 3 (not shown) relates to a block diagram of the control signal generator 1 which comprises a mixer for producing (fg+fo) from which is filtered the Pth harmonic which is squared and integrated to provide the required triangular wave which, in turn, is fed into a comparator together with the output of divider 3. The comparator output is distributed by means of a ring counter to the various rectifiers of the cycloconverter. A phase-locked oscillator, arranged to oscillate in phase quadrature with the fundamental frequency of the output, may be used to replace the circuit 7.
