Title: Aluminum Armature and Method for Making Same
IPC: H02K23/54
Filed: 1968-03-29
Abstract: 1,193,014. Making armatures for dynamo-electric machines; welding by pressure. PHOTOCIRCUITS CORP. 29 March, 1968 [3 April, 1967], No. 15361/68. Headings B3A and B3R. [Also in Division H2] An armature comprises a plurality of arrays of stamped-out aluminium conductors interconnected so that successive conductors lie in different arrays, adjacent arrays having insulation between them and the conductors of one array being partially provided with copper surfaces to form a commutator. Fig. 2 shows the construction of a disc armature wherein aluminium sheets 20, 21 are stamped to form conductors 11 with inner and outer tabs 10, 13. The sheets are then placed face to face on either side of an insulating disc 22 and the tabs joined to form complete winding turns interconnected as an 8-pole wave winding, the unwanted material of the sheets being removed at suitable times during the operation. The conductors formed from sheet 21 carry the copper surfaces 11<SP>1</SP>. Fig. 6 shows the armature forming part of a motor comprising a two-part casing 40 each part carrying respectively a ring of permanent magnet polepieces 41 and an iron ring 43 located adjacent opposite faces of the armature. Brushes 54 engage the copper surfaces 11. The armature may have more than two superimposed arrays of conductors, the tabs thereof being interconnected to form a winding with multi-turn coils (Figs. 7-10, not shown). Several methods of producing the armature are described. For example, one of the aluminium sheets may have a copper surface initially formed thereon, e.g. by plating, which is subsequently etched away to form the commutator using a masking process. Alternatively copper may be applied where required to a masked blank or stamped or assembled array of conductors by plating. In another method a copper foil track and an aluminium blank are first sandblasted and the foil is then bonded to the aluminium using platens, heated, for example, to 600‹ C. and applied with a pressure of about 1000 p.s.i.

Title: Improvements in or relating to apparatus for continuously determining the correlation function between two waves of varying amplitude
Inventor: CLYNES MANFRED EDWARD
IPC: G01S7/292
Filed: 1963-04-18
Abstract: 1,016,188. Cross correlation detectors. TECHNICAL MEASUREMENT CORPORATION. April 18, 1963, No.15416/63. Heading G1U. An apparatus for continuously determining the correlation function between two time varying waves f1 and f2 of varying amplitude consists of a pulse modulator P1 for converting the first wave into pulses having a repetition rate which depends on the instantaneous amplitude thereof, a selector S which cyclically enters the pulses into one of a circular series of memory locations M1-M100 to obtain a count thereof after first erasing the previous count and a read out circuit Ro for scanning the series of locations during each cycle beginning at the location following the selected location to produce a series of analogue values corresponding to the counts in the locations, the pulses during succeeding cycles being entered into successively selected locations in the series. Also incorporated are a multiplier Am for multiplying the analogue values with the second wave to produce a product and an arrangement which derives from the product a series of analogue values representative of the correlation function. This arrangement can be similar in form to the arrangement by which f1 is converted into a series of stored digital numbers and consists of a pulse modulator P2 whereby the product signal is converted into a series of pulses whose frequency at any instant represents the instantaneous amplitude of the product, this instantaneous value being stored as a number in one of the locations of a memory device D2. The required correlation function is given by for any given time delay γ introduced between f1 and f2, and as outlined above the changing values of f1 are stored over a period of time in memory device D1 and delayed by an amount fixed by timing circuits before being multiplied at Am with the function f2 over a similar period of time. This product is stored in the locations of the memory D2 and the read out combines the contents of all the locations to produce the required integral for one particular value of the delay γ. After all (say 100) locations of D2 have been scanned by the read out, a pulse is delivered which activates control circuitry Cp which alters by one position the location at which read out in the memory D1 begins, so that for the next time period the delay y is changed by one increment and the final record will indicate the correlation function for this new delay. Thus a series of functions at different delays are obtained so that a correlation curve may be produced. A timing pulse generator Tg produces suitable timing pulses to synchronise the overall operation of the system.

Title: An improved dimming device for automobile head-lamps and other search-lights
IPC: F21V19/04
Filed: 1929-05-22
Abstract: 329,173. Giese, P. May 22, 1929. Mounting electric lamps in lanterns.-In a vehicle lamp or other searchlight, both the source of light and a dimming device are mounted inside the reflector on a carrier attached to a sleeve through which pass the electrical conductors and the means for controlling the dimming device. Two or more lamps may be attached to a rotary axle so that any lamp may be brought to the focus of the reflector by an electromagnetically operable, switching device. In the form shown, the sleeve 4 carries two tubular arms 6, 7. These support the spindle 8 bearing three electric lamps which emit different kinds of rays, and a turning device. Two discs 13 and 17, the former fixed to the axle and the latter freely rotatable, have three ratchet teeth each on adjacent faces, and are pressed together by a helical spring 18, which also tends to rotate the disc 17 in a counterclockwise direction, a pin 21 limiting this motion. When a current is passed through the electromagnetic device 28, the cord 20 is pulled and rotates the disc 17 in a clockwise direction. When the lost motion x has been traversed, the pin 16 is disengaged from the bore in the disc 13 by the projection 22 pressing on the projection 23, and the disc 13 is rotated until the next lamp is brought into focus. It is then engaged by the pin 16, now released. On releasing the cord, the spring 18 brings the disc 17 back to its original position, the disc rising on the teeth of the lower disc and being held up by the nose 22 passing over the projection 23 while the lost motion is being established. The lamp brought into focus at the same time enters the electric lighting circuit.

Title: Improvements in and relating to electric valve circuits for controlling the supply of alternating current to a load circuit
IPC: B23K11/24
Filed: 1943-09-28
Abstract: 598,290. Control systems for consumption apparatus. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 28, 1943, No. 15876. Convention date, Sept. 30, 1942. [Class 38 (iv)] Intermittent energization of a load 10, such as a resistance welding transformer, from an A.C. source 11 for a predetermined number of half cycles is effected over a grid controlled valve 14, the conductivity of which is controlled by an R.C. circuit 20, 21 of low time-constant in combination with a timing circuit 32 which controls the charging of the condenser 20. Normally the condenser is charged each cycle when a tube 33 of the timing circuit conducts and the condenser voltage, in series with a hold-off voltage provided by winding 22 of a former 23 and an opposed peaked voltage from a transformer 31, is applied to the grid of valve 14 to maintain the valve non-conducting. The timing circuit allows conduction of tube 33 to be prevented for the predetermined number of cycles so that valve 14 conducts-and energizes the load for a corresponding number of half cycles due to the quick discharge of condenser 20 by resistor 21. Preferably, a valve 15 trails valve 14 and energizes the load during the alternate half cycles. the peaking transformer 31 is fed from an adjustable phasing circuit 29, 30 whereby the points in the A.C. cycle at which the valves conduct may be controlled. Cyclic conduction of tube 33 is provided by a grid excitation circuit comprising a winding 46 of transformer 23 and an R.C. circuit 42, 43 connected by a normally closed weld-initiating switch 45, the arrangement resulting in grid rectification. A shield grid 37, energized from winding 46 through a phase shifting circuit 40, 41, delays conduction of the tube until the 90-degree point of the anode voltage cycle. Upon operation of the initiating switch the A.C. voltage input to grid 36 is reduced to that appearing at the adjustable tapping 48 of a potentiometer 49 shunting part of the winding 46 ; the tube consequently ceases to conduct until the charge on condenser 42 falls to a lower value by leakage through the adjustable resistor 43 and the load circuit is energized during alternate half cycles of this period by valve 14. A transformer 60 in parallel with the load circuit nullifies, when valve 14 conducts, a hold-off bias provided by a further winding 64 of transformer 23 on a tube 59 which fixes and reduces the hold-off bias on the trailing value 15 derived from winding 54. The valve subsequently conducts under the control of winding 53 of the peaking transformer. For half cycle-working a switch 66, ganged with the control member of the timing resistor 43, is closed to shunt a resistor 67 across the transformer 60 to prevent conduction of tube 59.
