Title: A continuous and automatic moulding machine suitable for making sweetmeats, biscuits and the like
IPC: A23G3/02
Filed: 1931-02-26
Abstract: 365,382. Endless - chain moulding- machines. ETABLISSEMENTS J. DAMOY, 31, Boulevard Sebastopol, Paris. Feb. 26, 1931, No. 6061. Convention date, March 5, 1930. [Class 87 (ii).] An endless-chain moulding-machine is formed with moulding elements which are situated clear of the running chains or sprockets, and are carried by pivots arranged below the plane of their lower surfaces.. In the illustrated form shown in inverted plan in Fig. 1, and in detail in Figs. 3 and 6, the mould elements 2 are formed in the edges of co-operating slats 1 which are pivoted to the sprocket chains C on outwardly projecting pins 54 screwed into the links 55 and passing through downwardly projecting bosses 50 on the slats. These offset pivots ensure that both tops and bottoms of the moulds are separated as shown at Fig. 7 when the chains pass over the sprocket wheels, thus facilitating cleaning by brushes. The rear sides of the slats are cut away underneath the moulds as shown at 58, Fig. 6, to collect excess material squeezed out of the mould and deliver it by gravity when next the chain is travelling with the moulds in an upright position.

Title: Improvements in revolution counters for controlling the operation of associated machines
IPC: G06M3/02
Filed: 1948-02-27
Abstract: 665,608. Counting apparatus. SANSONE, C. Feb. 27, 1948 [May 4, 1943], No. 6163/48. Class 106 (i) A counter adapted to stop a loom, or other associated machine, after a preset number of revolutions incorporates a number-setting dial as used in automatic telephones for presetting in turn the digits of the number required. The dial 5 is connected through spur gears 23, 22, 4 and 6 with a shaft 2 on which are freely mounted a series of wheels 1 meshing with the numeral wheels 3 of the counter. Secured to the shaft 2 is a yoke 7 carrying a series of driving pawls 8 for the wheels 1. The pawls 8 are released in turn for engagement with their respective wheels 1 by step-wise rotation of a controlling cam-shaft 9 which occurs when a ratchet wheel 10 on the camshaft strikes a fixed pawl 11 as the yoke 7 returns to home position after release of the dial 5. Thus, as each digit is dialled, the yoke 7 is rocked clockwise an amount commensurate with the digit and a pawl 8 turns its wheel 1 and numeral wheel 3 correspondingly. When the dial is released the yoke returns and the pawl 8 ratchets idly over the wheel 1, finally passing out of engagement with the wheel and on to an abutment 15. Towards the end of this movement the ratchet wheel 10 strikes the pawl 11 and the cam-shaft 9 is turned one step to bring the next lower order pawl 8 into action ready to register the next digit. When " 0 " is dialled, the pawl 8 does not leave the abutment 15 to actuate its wheel 1 but the shaft 9 is stepped to prepare the next pawl. " 00 " is dialled in one operation, the higher order numeral wheel being given a complete turn and the ratchet wheel 10 being stepped twice by the provision of a second pawl 12 which it then strikes in addition to the pawl 11. A handle 17 is turned to release the counter transfer pinions 16 before setting a number, this also setting nines on the counter wheels, one unit being added in when the handle is again operated to restore the transfer pinions after setting. When the counter has returned to zero, a cam 18 actuates contacts 19, 20 to stop the machine driving it.

Title: Improvements in or relating to electric wave transmission systems
IPC: H01J25/12
Filed: 1941-05-16
Abstract: 564,890. Electron-oscillators dielectric wave - guides. ELECTRICAL RESEARCH PRODUCTS, Inc. May 14, 1941, No. 6217. Convention date, May 17, 1940. [Classes 39 (i) and 40 (v)] A tubular wave-guide 1, Fig. 1, is doubled back and forth across the path of an electron stream 4 through a straight tubular chamber 6 intercepting the guide at a number of points a, b, c at which the electrons are exposed to interaction with the field associated with an electromagnetic wave propagated along the guide, the wave transmission through the guide and the electron transit time between interaction points being so related that the interaction is cumulative. The interaction produces velocity modulation and bunching in the stream which, after. passing through drift tube 39, may deliver energy at points d, e, f to maintain an amplified wave in a second guide 2. The guides are terminated by conducting closures 36 spaced an odd quarter wave from the last interaction points c, d, or terminating impedances equal to the surge impedance may be employed. Output and input may be transmitted by coaxial lines, or by extending the wave-guides, or the input and output may be coupled together by a guide to generate oscillations which are taken off by a coupling loop. In Fig. 1, the folds of the guides are spaced apart so that the electrons spend only a fraction of their time in the guide, the remainder being spent in tubes 37, 38 ; for H1 waves the time from a to b should be a whole cycle for the electrons and a half cycle for the waves. If the folds are close together, the electrons spend the whole period in a guide, and to screen off undesired parts of the cycle screens 40, Fig. 5, may extend into the guide. Screens 37 ... 40 are made of radius too-small to propagate waves. In Fig. 7, the bends in the guide are not rectangular but curved, and to compensate for the variation in average electron velocity along the beam, the distances bc, de are made greater than ab, ef, while the lengths agb, bhc remain equal ; alternatively, agb may be made greater than bhc, while distances ab, bc, de, ef remain equal. The electron velocity may also be reduced in the centre by inserting midway between gun accelerating electrode 15 and collector anode 5 an electrode which is at a lower potential than either. The cross-section of the guides may be rectangular.

Title: Sensing device for flocculent precipitates
Inventor: PRIESTLEY PHILIP THORPE
IPC: G01N31/02
Filed: 1968-02-09
Abstract: 1,235,123. Photo-electric investigation of precipitates in liquids. KODAK Ltd. Feb.6, 1969 [Feb.9, 1968], No.6447/68. Heading G1A. The flocculation of a precipitate is investigated by a differential arrangement of photo-cells sensing the movement of the flocculent precipitate through a predetermined distance. Depending on whether the precipitate is aerated or settling, the upward or downward speed of movement is measured. In the recovery of silver from photographic waste material, an aerated precipitate is formed and a measure of the progress of flocculation is of interest. The apparatus of Figs.1 and 2 may be used for determining the rise-time of the flocculent precipitate over the distance between the two photocells 20, 21, which measure light transmitted through sample chamber 1 from sources 23, 24. A liquid sample containing a flocculent precipitate is passed, via bore 3 and gasket 5, into the chamber, the pneumatically-controlled plunger at this time blocking the outlet of bore 3. The incoming liquid forces the piston 17, fitted with sealing rings 19, and which was intitially positioned at the bottom of the chamber, upwards until it abuts contacts 16, thereby closing a circuit to relieve the air-pressure on plunger 7 and open the bore 3. Measurement of the movement of the precipitates now takes place. Initially it is evenly dispersed through the liquid and the outputs of cells 20, 23 are balances so that differential amplifier 33 produces no output. Once the precipitate starts to rise, however, an unbalance signal is produced to operate relay 34 close contact 35 and cause capacitor to start charging. Only when the precipitate has all collected on the liquid surface above the photo-cell 21, are the cell outputs once again balanced and capacitor 37 stops charging, the voltage attained measured by voltmeter 38 indicating the rise-time. After this measurement, the clarity of the sample may be determined from the ratio of transmitted (measured by cell 20) to scattered light (measured by cell 22 mounted at right angles to the direct beam from source 23). The cells 22 is in the feedback loop of an amplifie 39 whose output is indicated by motor 41. The closing of contacts 16 actuated a delay mechanism to allow measurement to proceed before air, introduced through pipe 15 causes the plunger move downwards to eject the sample simultaneously cleaning the inner walls of the chamber.

In a drive for an aircraft alternator an inner shaft 7 carrying a drive sprocket 9 has a splined connection 6 with the main alternator shaft 5 and is movable axially to disconnect the sprocket from the main drive, disconnection being effected by projecting a pin 39 radially inwards to hold stationary a nut member 15 which is normally rotated with the shaft. The nut member 15 is coupled to the drive shaft 7 by an intermediate screwed sleeve 12 with internal and external threads of opposite hand and the members are normally secured together by a radial shear pin 23. To disconnect the drive a solenoid-operated stop, Fig. 2 (not shown), is retracted to allow the pin 39 to be projected inwards by a spring 26 and engage one of a pair of lugs projecting from the member 15, which is thus held stationary, and the pin 23 shears at the inner or outer surface of the sleeve 12, according to the direction of drive, to effect displacement of the shaft 7. The movement of pin 39 cuts off the supply of lubricant to the bearings 3, 4 through passages 43, 44, 45, 47. For a one-way drive arrangement the intermediate sleeve 12 may be omitted.

Title: Improvements in or relating to circuits for inverting the sense of variations of a voltage
IPC: G05F1/52
Filed: 1950-03-17
Abstract: 698,241. Automatic voltage control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 17, 1950 [March 22, 1949], No. 6727/50. Class 38 (iv). [Also in Group XL (c)] The D.C. voltage derived from a pulse source is maintained constant by feeding a fraction of the voltage over a sense or phase-inverting circuit (see Group XL (c)) to vary the bias on the valve generating the pulses. The circuit is particularly applicable to the generation of E.H.T. voltage in a television receiver. A sawtooth wave causes a valve 1 to generate pulses in inductor 3 which are rectified by diode 4 to produce a high D.C. voltage at terminal 6. A D.C. voltage is taken from the join of resistors 10, 27 and fed to the sense-inverting device 12, together with the pulse voltage. As the load is increased, the negative D.C. potential on line 11 increases, causing an increasing positive potential to be fed from the device 12 to lower the bias on valve 1 so that it passes a greater current to give a larger pulse. In a modification, Fig. 2 (not shown), the controlling voltage is derived from a potential divider across the D.C. output, and an auxiliary source of alternating voltage may be used.

The anode/cathode current of a cavity magnetron (represented as Z) is maintained substantially constant by connecting a pentode 6 in series with the negative line of the supply, the potential of the control grid of the pentode being controlled by the voltage drop across the cathode resistor R due both to the load current and to the current in the circuit comprising resistor R, neon lamp 13 and resistor X. This additional current provides a compensation for changes in input voltage. The neon lamp 13 maintains the cathode/screen voltage constant. The resistor X has a value of m times the value of the resistor R, where m is the amplification factor of the valve.
