Title: Improvements in and relating to feeding or conveying biscuits or other articles
IPC: A21B5/02
Filed: 1937-12-10
Abstract: 507,222. Conveyers. PATERSON, J. C., and BAKER PERKINS, Ltd. Dec. 10, 1937, No. 34324. [Class 78 (i)] In a system in which biscuits or like articles are conveyed in a continuous column of rows, rows of biscuits are raised temporarily in succession above the conveying surface and restored thereto so that the interval between the rows is diminished and the column split into batches. The conveying surface 9 is composed of parallel spaced apart endless cords, chains or tightly coiled springs, and is supported on guides. Thin slats 12 pass between the cords 9 and are mounted upon spindles 16, 17 which are raised and lowered by mechanism actuated by a rotary cam 18. The upper edges of the slats are inclined to the conveying surface as shown, so that as the slats rise, the biscuits will be raised in succession commencing with the row on the right, and on descent will be redeposited in succession from the left, thus diminishing the interval between the rows. The spindles 17, 16 are connected to pairs of levers 26, 31 mounted on rock shafts 25, 30. Arms 24, 29 on these shafts are connected by links 23, 28 to a bellcrank lever 22 and arm 27, respectively, fast on a shaft 127. The bell-crank lever is rotked by a rotary cam 18 driven from the pan conveyer. If a row of biscuits is so placed that it overhangs the forward ends of the slats as they pass upwards through the conveying surface, light spring tongues 34 maintain it in contact with the slats. The biscuits are stripped from the oven conveyer 5 by a knife 7, and after being formed into batches on the conveyer 9, are discharged by a conveyer 8 into pans.

Title: Radar speed measuring systems
IPC: G01S13/60
Filed: 1974-07-19
Abstract: 1468159 Radar BRITISH RAILWAYS BOARD 19 July 1974 [20 July 1973] 34637/73 Heading H4D In a train- or other vehicle-mounted radar speed measuring system there are included aerial means for directing a radio beam to the ground and for receiving waves reflected therefrom, means for producing an A.C. signal whose frequency band corresponds to the Doppler frequency band, and means for processing the A.C. signal to produce a speed measurement output. A high-pass filter is connected between the A.C. signal producing and processing means and is continuously adjusted via a control circuit in a feedback path from its output so that its cut-off frequency always substantially corresponds to the frequency of the component of the A.C. signal having the maximum amplitude. As shown in Fig. 1, the Doppler input is fed via a filter 1 to a zero crossing detector 2, which produces a rectangular pulse train. This is fed to a line driver 3, which is connected to indicating and counting equipment providing a speed measurement. Output from the detector 2 is also fed to a frequency to voltage converter 4, which may be of diode-transistor pump type, and which provides a control voltage V for the filter 1, via shaping circuits 5. The filter comprises an operational amplifier OA1, Fig. 2, and a matched pair of field effect transistors Q1, Q2 whose resistance is adjusted continuously by the control voltage V so that the cut-off frequency corresponds closely to the frequency of maximum amplitude. Hence, unwanted lower frequency components are largely eliminated.

Title: Improvements in or relating to methods of and apparatus for spectrum analysis
Inventor: MERTZ LAWRENCE NELSON
IPC: G01J3/26
Filed: 1962-09-13
Abstract: 972, 265. Photo-electric spectroscopy BLOCK ENGINEERING Inc. Sept. 13, 1962, No. 34958/62. Heading G1A. The invention relates to an optical method of analysing a spectrum from a source, particularly a rapidly fluctuating source,using an interferometer 20 having a mirror 26 capable of reciprocating motion along an axis normal to its reflecting surface, and having photo-electric detecting means 30 in its light exit path, which comprises the steps of directing light from the source through the interferometer, reciprocating the mirror such that the velocity of the mirror along the said axis is substantially constant for a portion of each reciprocating cycle, and analysing the frequency components of an output signal from the photo-electric device during the period of constant velocity of the mirror, whereby the relative amplitudes of the various frequency components of the signal indicates the distribution of the energy of the light source among its various component light wavelengths. In the embodiment shown light from the source is directed through a lens 10 into a Michelson interferometer 20 where it is divided equally by a beam splitter 22 into two beams one of which is deflected to a fixed mirror 24 and the other of which continues in the same direction as the incident light to strike the reciprocable mirror 26. In known fashion these beams are reflected back to the beam splitter where they interfere and a portion of the total available light is directed on to a photocell 30. As the mirror 26 reciprocates the resultant signal from the photo-cell 30 is fed to a conventional frequency analyser 44 through an amplifier 40 and the amplitude of the component frequencies of the signal analysed, as previously explained, indicates the wavelength distribution of the incident light. The mirror 26 is caused to reciprocate by an electrodynamic motor 27 similar to the coil and magnet structure of a conventional loudspeaker, the motor being supplied from an amplifier 34 controlled by a saw tooth oscillator 36. The high frequencies in the output signal of the photo-cell 30 during the return stroke of the mirror 26 will normally be outside the range of the analyser but if a large optical bandwidth has to be covered the return stroke signal can be blanked off by known apparatus. In a further embodiment (Fig. 2 not shown) a tape recorder is interposed between the photo-cell 30 and the analyser 44 so that analysis of the signals may be performed at leisure and also the range of frequencies presented to the analyser may be expanded or condensed by varying the playback speeds of the recorder.

Title: Improvements in and relating to means for generating electricity by evaporating liquids
IPC: H02N3/00
Filed: 1927-12-29
Abstract: 308,382. Brunner, F. von. Dec. 29, 1927. Hydro-electric and like machines.-Electricity is generated by vaporizing a liquid, such as mercury, water or ammonia, and condensing the vapour in a device having means for leading the desired charge to the point of consumption, either the liquid or vapour or both being initially charged from a separate source of electricity. The condensate is returned to the vaporizer and a stream of air, gas or steam may be used to accelerate the passage of the electrified vapour from. the vaporizer to the condenser. In the form shown, the liquid 3 is evaporated by a flame E in a vessel A which communicates through a pipe 4 with a condenser B immersed in a cooler C, the vessels &c. being preferably made of or lined with badly-conducting materials. Metal plates 1, 1<a> in the two vessels serve respectively to convey the initial charge to the liquid from an electrostatic machine or Leyden jar apparatus D and to convey the desired charges to the consumption circuits, the system of these plates being completed through equalizing pairs of pointed conductors 14, 15 and 16, 17. The condensate flows back into the vessel A through a pipe 18 and funnel 19 with an intervening air-gap. The passage of the vapour through the pipe 4 mav be assisted by a stream of compressed air or the like introduced at 8, the spent accelerating medium being removed by a device not shown on the drawings. The initial charge from the source D may be applied to the vapour by a point-discharge device 7 instead of being given to the liquid at 1. The voltage of the desired charges is controlled by regulating the accelerating medium. the distance between the conductors 14, 15 and the temperature difference between the vaporizer and condenser. The quantity of the charge is determined by the size of the heating and cooling areas.
