Abstract: 404,464. Coin-freed apparatus for delivering electricity, gas, &c. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Jan. 25, 1933, No. 2435. Convention date, Jan. 25, 1932. [Class 27.] Time-controlled apparatus.-In prepayment devices wherein the quantity of commodity supplied e.g. electricity, gas, or water, is controlled solely by a time actuated mechanism governed by the insertion of coins, the time actuated mechanism with its reduction gear drive is constructed as an independent unit adapted to be coupled to a second unit comprising the coin and quantity mechanism, the arrangement being such that either unit may be removed for repairs &c. without disturbing the other. The time mechanism comprises a small self-starting synchronous motor 2 having an excitation winding 3 and a stator embracing a reduction gear the driving shaft of which is shown at 5, the motor and reduction gear being an independent unit mounted on a base-plate 1. The second unit comprises a coin and quantity mechanism 6, the delivery or quantity mechanism of which is coupled to the drive 5 through transmission wheels 7, 8. The wheel 7 has pins 70 meshing with the teeth of wheel 8, and the position and number of these pins may be adjusted to various charging rates. When the pins are being changed, the wheel 8 is held by a yieldingly controlled roller. The current to the motor 2 may be cut off at the same time as the supply of commodity, or the motor may move the quantity mechanism to a limiting position beyond its zero position. For this purpose, the quantity mechanism may have a control member which in the limiting position opens a switch in the excitation winding 3, or a friction clutch may be interposed in the transmission gear, one part of which is locked by a control member operated by the quantity mechanism in the limiting position.

Abstract: 706,108. Fluid-actuated valves. MONITOR ENGINEERING & OIL APPLIANCES, Ltd. Jan. 30, 1952 [Feb. 3, 1951], No. 2733/51. Class 135. [Also in Group XI] An oil burning apparatus in which a pressure regulator admits gas from a compressor gas source to maintain a predetermined constant pressure in the fuel tank has a valve operated by a diaphragm biased towards the open position by a spring and exposed on the spring side to atmospheric pressure and on the other side to the fuel tank pressure and the diaphragm is connected to a valve operating plunger by means of a flat strip lever pivotally mounted by means of a transverse part cylindrical portion thereon. The fuel tank 18 is connected through a pipe 30 to a chamber 25 formed at the bottom of a vessel 20 in which air is maintained at a pressure of about 100 pounds per square inch by means of a hand pump 23. A flexible diaphragm 27, Fig. 3, forming the lower wall of a chamber 25 and having one side open to atmospheric pressure through a hole 31 is deflected upwards by a spring 36 when the air pressure within the chamber 25 and hence tank 18 falls below a predetermined pressure to open, through a lever 33 and rod 29, a valve 28 in the bottom of the vessel 20. The diaphragm 27 is deflected downwards by the air entering the chamber 25 from the tank 18 to close the valve 28 as soon as the pressure in the chamber 25 reaches the predetermined value. The pressure exerted by the spring 36 on the diaphragm 27 may be adjusted by a screw 77. The lever 33 is pivotally mounted on a trunnion formed on the pipe union 62 to which the pipe 30 is connected. In the arrangement shown in Fig. 8 an air release valve 66 is opened by an extension 65 formed on the lever 33 should the pressure in the tank 18 rise above the predetermined value when the tank 18 is heated by the burner (see Group XI). The spring pressure on the diaphragm 27, Fig. 8, may be varied to suit different heat outputs of the burner by means of a leaf spring pivotally mounted at 68 and doubled over to form a loop 69 against which a stepped or " snail cam 70 is pressed on rotation of a spindle 71 of a hand operated heat regulator or stop valve 39 controlling the amount of fuel supplied to the burner. The initial pressure on the diaphragm 27 may be adjusted by a screw 75.

Title: Radio transmission and reception system
IPC: H03D9/06
Filed: 1941-03-05
Abstract: 585,207. Locating objects by reflected waves; velocity - modulated tubes. SAYERS, J., OLIPHANT, M. L. E., and WRIGHT, C. S. March 5, 1941, No. 2988. [Classes 39 (i) and 40 (v)] In a " radar " system the transmitting oscillator 8, Fig. 3, has two periods of natural oscillation, one is fed to the transmitting aerial 12, and the other to a mixer 15 for heterodyning the echo pulses received by the aerial 12<1>, the resultant intermediate frequency being amplified at 17 and fed to a C.R.T. oscillograph 18. Any disturbances, such as temperature changes, affect both frequencies generated by oscillator 8 in the same manner and thus have little or no effect on the I.F output from the mixer 15. The two periods of oscillation are obtained by tightly coupling two oscillatory circuits, each having by itself the same period, and causing them to oscillate either in phase or 180 degrees out of phase. As shown in Fig. 2, the oscillator is of the velocity modulated type, the. " buncher " and " collector " circuits 5, 6 being tightly coupled by the loop 7. The phase relation of the circuits is controlled by the transit time of the electrons, that is by the anode voltage. A pulsing circuit 9 provides pulses of 1 microsec. at a frequency of 1000 p.p.s. to cause 10,000 volts to be applied to the oscillator, which then emits a frequency of 4.5 x 10<3> Mc. per sec. with a power output of 500 watts. Between the pulses 6,000 volts is applied to the oscillator which then emits a frequency approximately 45 Mc. per sec. less than before and at a power output of 20 watts. The pulsing circuit 9 also controls the time-base of the oscillograph 18. The mixer 15 may be of the catswhisker-crystal type, embedded in wax.

Title: Improvements in or relating to loading or unloading mechanism
Inventor: BROOKS ROBERT JOHN
IPC: B65G47/61
Filed: 1951-02-07
Abstract: 711,217. Conveyers. KING, Ltd., G. W. Jan 25. 1952 [Feb. 7, 1951], No. 3024/51. Class 78 (1) Loading and unloading mechanism for transferring articles to and from overhead conveyers comprises at least two bars adapted to be moved in an endless path, one bar having associated therewith a carrier member adapted to engage and transfer an article from an upper to a lower position while the other bar has associated therewith a carrier member adapted to transfer an article from the lower position to an upper position, the bars being rotatable about their longitudinal axes by actuating means disposed at predetermined intervals to cause the carrier members to perform their appropriate . function. As shown, a pair of endless chains is provided, travelling in parallel paths indicated by the chain line and travelling in the direction of arrows A. Bars 16 and 17 are journalled in bearings carried by the chains so as to extend between them and be capable of rotation about their longitudinal axes. One of each of the bars 16, 17, which alternate along the length of the chains, are shown. Each bar 16 carries centrally a pair of hooks 18 and near each end a fixed arm 19 provided with a roller 20, and a free arm 21, provided with a roller 22 and restricted in the clockwise direction by a stop on bar 16 (not shown). Each bar 17 carries centrally a pair of hooks 24, which may have rollers 24a to assist in their transferring action, and near each end a pair of fixed arms 25 carrying rollers 26a, 26b. The arms 19, 21 and 25 operate in different planes, respectively, so as to be actuated by separate cam tracks 32, 27 and 28, and 29-31, respectively through the rollers 20, 22, 26a and 26b. In operation, as each bar 16 passes along the rising stretch of the chains rollers 22 engage tracks 27 which causes arms 21 to be pressed against their stops and so rotate bar 16, causing hooks 18 to detach a crankshaft from an overhead conveyer 10. Arms 21 are held in a raised position on the falling stretch of the chains by tracks 28 to keep them to the aide of conveyer 10 and an underlying conveyer 11 also of the overhead type, and near the bottom of this stretch rollers 20 are engaged by tracks 32 to cause hooks 18 to deposit the crankshaft on a grinding machine 12 .after which the cycle is repeated. As bar 17 approaches the bottom of the falling stretch rollers 26b engage tracks 30 to cause hooks 24 to pick up a ground crankshaft from the machine 12, rollers 26b passing to tracks 31 during the picking up operation which operate to steady the return of the hooks 24 to depending position. After proceeding around the cycle rollers 26a on their next passage along the falling stretch engage tracks 29 which cause hooks 24 to deposit the ground crankshaft on the underlying conveyer 11 for removal.

Title: Improvements in process and apparatus for detecting, controlling and analysing gases, mixtures of gases, smokes and dusts suspended in said gases
IPC: G01N27/66
Filed: 1933-02-01
Abstract: Gases or mixtures of gases, or impurities such as smoke and dust in gaseous fluids are analysed or detected by subjecting them to the ionizing action of particles emitted by a radioactive substance in an electric field, the electric charges resulting from the dissociation of the gaseous molecules forming an electric current which is amplified and measured or operates controlling, signalling, ventilating, or other apparatus.  The gaseous fluid is contained in or circulated through a chamber 3 within which is a cylinder 1 supporting a film 2 of radioactive material connected to the negative pole of a source of electricity 7.  An electrode 6 is connected to the positive pole through a potentiometer 10 and resistance 11, and also <PICT:0398722/III/1> <PICT:0398722/III/2> <PICT:0398722/III/3> to the grid 12 of an electron tube 8, in the plate filament circuit of which is inserted a measuring instrument such as a milliammeter 9, a recording device 9a, or a relay 9b controlling the circuit 15 of a control, alarm, or ventilating device.  The control instrument 9 may be inserted in a Wheatstone bridge circuit, the intensity of the current flowing being regulated by means of a rheostat.  The electrodes may comprise parallel plates, radioactive coated plates alternating with the uncoated ones, all of one kind being connected electrically.  Again, the electrode 6 may be bell-shaped and surround the cylindrical electrode 1.  A number of detecting elements may be disposed at different parts of an enclosure, the atmospheric conditions of which are to be tested.  In a modification, Fig. 7, the relay 9b operates by means of a battery 23 a source of light such as a neon lamp 24.  The rays pass through total reflection prisms 25 to a photo-electric cell 26, the current produced being amplified by the electron tube 27 and operating acoustic signal devices 28, 29.  The lamp may be inserted directly in the plate circuit of the electron tube. Ultra-violet, infra-red, mercury vapour, or other light may be used if the photo-electric cell is replaced by other suitable apparatus for conversion to electricity.  Fig. 9 shows a portable apparatus especially adapted for detecting deleterious or explosive gases in a gallery.  A casing 29 contains the amplifier and batteries, and carries the electrodes 1, 6, milliammeter 9, p  sound alarm 30, and coloured lamp 31.  The cylinder 1 is placed in the direction of the air current, the passage of air being improved by the provision of nozzles 33 and advantageously elements 34, 35 producing an injector effect.  In detecting fire-damp, the reading of the milliammeter varies with the percentage of methane present, and the alarm is arranged to operate when this reaches the danger point. The electrodes are fed with direct or alternating current.
