Title: Improvements in or relating to apparatus for playing games and for amusement purposes
IPC: A63H18/10
Filed: 1943-11-12
Abstract: 574,024. Games ; toys; amusement apparatus. SEARLE, G. R. Nov. 12, 1943, No. 18838. [Classes 132 (i), 132 (ii) and 132 (iii)] [Also in Group XXXV] An apparatus for a toy or for playing a game or for amusement purposes comprises a travel- ;ling member, a track for the travelling member having alternate sections oppositely inclined or having sections inclined in the same direction alternating with horizontal sections, the horizontal sections having means for retarding the travelling member, together with means under the control of an operator for imparting impulses to the travelling member when it is on sections of similar inclination or on a horizontal member. The sectional track 11 carrying rails 12 is supported by brackets 13 adjustably connected to supports 14 by slots 15 and bolts 16. Hollow rectangular formers 25-27 wound with coils 28 connected in circuit with a source of direct current surround the rails 12 on the sections 21-23. The vehicle 29 is adapted to travel on the track 11 through the formers 25-27 and may take the form of a motor car with wheels 30 carried on two axles 31 from which is suspended the soft iron core 32 by bolts 34, or may be a ball travelling in a groove or channel. The sections 17-20 of the track are adjusted so that when the vehicle 29 is placed at the upper end of one of these sections the action of gravity is just sufficient to overcome static friction and cause the vehicle to descend that section but insufficient to cause it to traverse the oppositely inclined or horizontal sections 21-23. Manipulation of the switch at the correct moment energizes the coil 28 and the electric field set up transmits an impulse to the core 32 so that it travels at an uninterrupted speed round the track 11. Alternating current and a non-magnetic core may be used or electromagnets or permanent magnets with electrically or mechanically withdrawn keepers may be substituted for the coils 28. The apparatus may be adapted for use as a race game or associated with coin-freed mechanism or constructed so that passengers may be carried in the vehicle, the passenger having control of the vehicle.

Title: Centrifugal separating machines
IPC: B04B11/08
Filed: 1936-07-08
Abstract: 474,534. Centrifugal machines. PECKER, J. S. July 8, 1936, No. 18966. [Class 23] A centrifugal separator has horizontally swinging scrapers to clear material deposited in the bowl; each scraper has cutting and shredding teeth at its outer end and a cleaning element automatically operable at the end of the clearing operation for cleaning the teeth. The bowl 2 is mounted on the vertical shaft 4 and is provided with a rubber lining 8<1> to increase the frictional grip of the deposited solids while the scrapers are operating. The rubber is brushed or sprayed on the wall of the bowl, or applied as a sheet and pins 9<1> assist in holding it in place. A seepage plate 8 is arranged at the top of the bowl as described in Specification 453,651. The hollow scrapers 1 are supported on vertical shafts 10, and a blade 15 is arranged so that it can slide through an opening at the free end of each scraper. A link 37 is connected by pivots to a lug 35 on the blade and to a crank arm 39 fixed to the spindle 40. A spring 45 is secured to one end of the link 37 and to a lug 47 on the outer wall 18 of the scraper. The upper end of the spindle 40 carries an arm 42, and as the scraper is rotated to its inoperative position, shown in Fig. 1, this arm 42 is brought into engagement with a fixed stud 43. This causes a partial rotation of the spindle 40, so that the blade 15 slides within the scraper and its teeth 16 are cleaned by the scraper edges. When the scraper is moved outwards to its operative position the arm 42 is carried beyond the stud 43 and the blade 15 is projected from the scraper by the spring 45. The teeth 16 of the blade 15 may have bevelled side faces as well as a cutting end, or they may have convex bevels at their rear faces. In the modification shown in Figs. 10, 12 the scraper 52 consists of a solid plate with a toothed blade 58 attached to it by screws. A cleaning plate 63 is attached to the scraper by pin and slot connections 65, 64 so that the slotted end 66 can pass over the teeth 60 to clean them. The cleaning plate is actuated by means of a lever 67 operated by a fixed cam 73 on the casing.

Title: Improvements in or relating to Apparatus for Measuring the Voltage of a D.C. Component in an Electrical Voltage
Inventor: MCDONNELL DENNIS
IPC: H03M1/00
Filed: 1966-04-30
Abstract: 1,153,201. Digital voltmeters. FENLOW ELECTRONICS Ltd. 24 April, 1967 [30 April, 1966], No. 19109/66. Heading G4H. [Also in Division H3] For measuring the value of the D.C. component of a signal which may also contain A.C., the signal is integrated for a period equal to one or more cycles of the A.C. supply so that the measurement is independent of the A.C. component having a frequency equal to, or an integral multiple of the A.C. supply. The signal to be measured is applied through a switch 55, Fig. 2, which may be a gate, to the integrator which comprises feed-back amplifier 60 and capacitor 61. Switch 55 is preceded by an adjustable-gain amplifier so that a suitable measuring range can be selected. The mains A.C. 160 is applied to a Schmitt trigger 161 which turns on during positive half-cycles and off during negative half-cycles. The trigger outputs control an oscillator 140 so that it runs at exactly 20,000 cycles for each cycle of the mains. Counter 180, fed from the oscillator through frequency halver E has a capacity of 10,000 when and it reaches this value it causes switch 55 to open. The integrator output is as shown in Fig. 4. At the end of the 10,000 pulse period, a voltage is applied for a small offset period to increase the value in the integrator. This is to avoid errors when measuring small D.C. components, the value added being compensated for in the measuring of the reference period. This the time taken to return the integrator output to zero by a reference signal of opposite polarity, applied via switch 114, 115. From the instant the reference signal is applied, pulses are gated to a binary counter until zero detector 70 responds. The value in the counter, representing the D.C. component in the input, is transferred to a store and thence to a printer. The period between read-outs can be adjusted. Oscillator frequency control.-Pulses 135, 136, Fig. 4 are derived from the Schmitt trigger output, one ending, and the other beginning at the end of the mains cycle. The pulses enable gates to which is also applied a pulse 134 derived from the counter 180 which should overlap each of pulses 135, 136 equally. The signals through the gates are subtracted and the difference signal, if any, is applied to control the oscillator frequency.

Title: Improvements in or relating to the breaking down of cartridges, rockets and the like
IPC: F42B33/06
Filed: 1924-08-12
Abstract: 242,011. Vautin, C. T. J., and Orchard, E. H. Aug. 12, 1924. Explosives, apparatus for treating; pyrotechnic devices. -A wet process for breaking down cartridges, rockets, and fireworks having paper or cardboard cases, and also applicable to wetting the contents of other classes of ammunition, consists in immersing the articles in water which is subjected to variations of pressure from atmospheric pressure to below or above atmospheric pressure, the treatment being continued until the contents are thoroughly wetted and the paper or cardboard has become pulped. The apparatus shown is applicable to breaking-down Verey cartridges to recover the metallic parts and the constituents of the " star " mixture. The tank A, filled with the cartridges and water, is exhausted to a vacuum of about 20 inches of mercury by an airpump B through a pipe fitted with a three-way cock C which can be turned to release the vacuum slowly. The application and removal of the vacuum may be repeated, hot water being employed if necessary to hasten the process of pulping. Hydraulic pressure up to 60 pounds per square inch may be employed instead of the vacuum, or pressure alternating with vacuum may be used. A propelling-charge escapes into solution, and, when a gate A<2> is opened, the solution and pulp pass through a sieve E into a tank F, the metallic parts passing to a receptacle G. The brass percussion-pap ends are removed as they emerge from the sieve and the metal containers for the " star " mixture pass between spiked rollers H, H<1>, which tear the containers open and drop them into an agitating chamber K where the mixture is dispersed in suspension in the water. The water passes to a filter-press M through a screen L which retains the metal parts. The mixture from the filterpress is washed and boiled to dissolve out the barium nitrate and is then dried and treated with a solvent of sulphur. The barium nitrate is recovered from its solution by crystallization.

Abstract: 395,872. Equalizing load on generator; automatic regulation. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Stoller, H. M. ; 63, Pollard Road, Mountain Lakes, New Jersey, U.S.A.) July 7, 1932, No. 19290. Convention date, Jan. 7. [Class 38 (iv).] The frequency of an alternator driven by an internal-combustion engine and supplying current to a variable number of synchronous motors is maintained constant by connecting a variable auxiliary load to the alternator, the auxiliary load comprising three-electrode discharge tubes which are connected in such a manner that their effective impedances vary inversely as the frequency of the alternator. Preferably the sum of the maximum values of the auxiliary and normal loads exceeds the maximum power of the internal-combustion engine. The Figure shows a three-phase alternator 1 driven by an internal-combustion engine 2 and supplying current to a number of synchronous induction motors, such as 10, 12. To maintain constant the frequency of the alternator, a variable auxiliary load comprising Thyratron argon-filled discharge tubes 18, 19, 20 and resistances 21, 22, 23 is connected in delta across the slip rings 6, 7, 8 of the alternator, the magnitude of the auxiliary load being controlled automatically from the frequency of the alternator by variation of the phase relationship between the potentials applied to the grids and anodes of the discharge tubes. For this purpose the grids are connected to secondary windings of transformers 37, 38, 39 having primary windings connected across a combination of resistance, inductance and capacity elements 40 .. 44 which is supplied with current from the output vertices of bridge circuit 25. The values of the resistances 41, 43 are such that the potentials applied to the primary windings of transformers 37, 39 lag by 60‹ and 120‹ respectively the potential across the primary winding of transformer 38, and the grid connection to transformer 37 is reversed,so that voltages applied to the grids of the discharge tubes differ in phase from one another by 120‹. The bridge circuit 25 comprises arms 28, 29 tuned to the normal frequency of the alternator, and resistance arms 26, 27 which are slightly unbalanced so as to produce, when the alternator is running at normal speed, a voltage vector at the output vertices of the bridge which is in phase with the voltage applied to the input vertices. The potential applied to the input vertices of the bridge is supplied by a secondary winding 30 of a transformer 31 the primary of which is connected across one phase of the alternator. The transformer 31 has also secondary windings 32, 33, 34 which supply heating current to the filaments of the discharge tubes. Specification 292,528, [Class 38 (iii), Electric motor control systems &c.], is referred to.
