Title: A device for actuating electrically operated counting mechanisms, particularly in taximeters
IPC: G07B13/00
Filed: 1953-12-29
Abstract: 745,507. Counting-apparatus; taximeters. HALDEX AKTIEBOLAG. Dec. 29, 1953 [Jan. 20, 1953; Dec. 8, 1953], No. 36034/53. Classes 106 (1) and 106 (3). In counting mechanism, particularly for a taximeter, in which a mechanical driving member 1 actuates a switch arm 3 controlling the solenoid 7 of a counter, the solenoid actuates a contact member 45 to open its own circuit, the contact member being locked in the open position until the next actuation of the switch arm 3. The arm 3 is rocked by a cam 1 rotated by the wheels of a taxi or by clockwork. Initially each rocking of the arm 3 serves merely to advance a ratchet wheel 9, carried by the arm and co-operating with a stationary advancing pawl 12 and a locking pawl 11, against a spring 15. After a number of actuations corresponding with the minimum fare, a slot 22 in a disc fast with the wheel 9 is aligned with a fixed stud 17 and the arm 3 is able to drop below the position shown to close contacts 4, 5 in the circuit of the solenoid 7 which consequently advances the counter. The armature 23 of the solenoid is coupled by a toggle spring 42 to a contact arm 45 which is thus rocked about its pivot 44 to open contacts 40, 41 to deenergize the solenoid. The arm 45, however, is held by a latch 48 which engages an abutment 49 of the arm, and the latter is only freed when the switch arm 3 is next raised by the cam 1. Thus, no matter where the cam stops, the solenoid does not remain energized. The ratchet wheel 9 may be reset by raising the arm 3 so that an arm 37 fast with the locking pawl 11 is rocked by a stud 38.

Abstract: 1,049,606. Machine tool details; automatic lathes. GEORGE KINGSBURY & CO. (GOSPORT) Ltd. Aug. 31, 1965 [Sept. 3, 1964], No. 36092/64. Headings B3B and B3T. An automatic lathe includes hydraulic actuators connected to its top slide, headstock slide and collet mechanism, the actuators being controlled by adjustable pneumatic timing relays, solenoid valves operated by the relay contacts, limit switches actuated by the collet mechanism, relays controlled by the limit switches, and a plug-board to which the relay windings and certain relay contacts are connected for selective connection by plug cords to produce a desired sequence of operations. At least one of the hydraulic actuators has an adjusting means to reduce its rate of movement to a desired rate at any point in its stroke. In the embodiment described a lathe having a headstock 12 (Fig. 1, not shown) has an actuator 26 operating a headstock slide 25, an actuator 18 (Fig. 3, not shown) operating a cross-slide 17 and an actuator 22 operating a top slide 21. The tailstock may also have an actuator 32. The control equipment is contained in a cabinet 35 (Fig. 1, not shown) having a control panel 36 which includes a switch for allowing manual operation and selective operation of individual actuators for setting up. At the rear of the cabinet 35 and integral therewith is an hydraulic fluid tank 37 fitted with a motor-driven pump 38. The components to be machined are fed by a vibrating feed mechanism 43 up a helical path to a shell 44 from where they fall into a shoot 45 which leads to a feed box mechanism carried on the headstock slide and which firstly aligns the components with the collet and then hydraulic pressure causes a secondary actuator to push the component into the collet. A detailed description is given of the top slide actuator (Figs. 4 and 5, not shown) which includes the adjustment for varying the rate of feed of a cutting tool.

Title: Radar systems
IPC: G01S13/70
Filed: 1973-07-30
Abstract: 1367600 Radar SIEMENS AG 30 July 1973 [15 Sept 1972] 36132/73 Heading H4D A radar system is provided with means for initially operating in a target acquisition mode and for automatically switching to a target tracking mode. The system comprises a receiver, echo-processing circuits provided with a plurality of range gates, a displaceable range window for use in the tracking mode, and a store to mark the range gate involved after acquisition of a target. The marking serves to displace the range window in time by means of a followup circuit, which remains operative until an echo signal from the target appears in said window, when a stop signal is applied to said circuit. As described, a transmitter and receiver are combined in a unit RG connected to an aerial AT which during the acquisition mode is circularly scanned, and which during the tracking mode is conically scanned. The received echo signals are supplied from the unit RG to a first bank of range gates ET1, which has separate range channels K1 to Kn. A second bank of range gates ET2, to which the echo signals are also applied, splits part of the range span of the range gate bank ET1 into a number of smaller range channels, K1a to K1f. As shown, the time position of an echo pulse E1 is within the range channel K1 of the range gate bank ET1. From information obtained from channel K1, the range gate bank ET2 is so placed that it definitely covers said channel. The outputs from the range channels K1a to K1f are connected to a store SP for marking purposes, this store retaining information as to which range channel in the bank ET2 has picked up an echo signal during the acquisition mode (in this case, channel K1d). A target tracking circuit GEF has a displaceable range window EF, and is also supplied with the received echo signals. A follow up circuit NS displaces the timing of the range window EF towards the marked channel K1d until they coincide, when output EA from said range window switches off said follow up circuit. Tracking then continues conventionally, information passing from the range window EF and the circuit GEF to an analyser or indicator circuit AS. The store SP may be arranged to retain only a signal corresponding to a target of shortest range, should there be more than one, as a counter to simulation of pulses by enemy jammers.

Abstract: 841,753. Electromagnetic stirring. ALLMANNA SVENSKA ELEKTRISKA A.B. Nov. 11, 1958 [Nov. 16, 1957], No. 36157/58. Class 86 Coils for stirring molten metal electromagnetically are so arranged that the full power of a 2-phase generator may be delivered to either of two sets of coils, or both may be energized simultaneously with reduced power. In the embodiment of Fig. 1, the switches 4 enable one or both sets of coils 1a, 1b, 2 to be energized, and the coils are tapped so that part may be shunted when both sets are in use simultaneously. Coils 1a, 1b of each set are connected in series with coil 2 of the other set and each system 1a, 1b, 2 is fed from a separate phase of the generator; this arrangement compensates for any difference in voltage between the two phases. In a modification, Fig. 2 (not shown), the coils are untapped. Full power may be applied to one set, or half power to both sets in series by reducing the frequency, e.g. by a Schrage motor, so that the voltage dip over each coil is reduced to half. In another embodiment, Fig. 3 (not shown) the set of coils may be energized at full power or both sets put in parallel by means of switches 5. In this case the frequency is increased in order to obtain maximum stirring power at half current.

Filed: 1929-11-26
Abstract: 343,197. Brake shoes acting on drums. EVANS, E. R., 1826, Diversey Parkway, Chicago, U.S.A. Nov. 26, 1929, No. 36183. Convention date, May 27. [Class 103 (i).] The operating cam 48 for a pair of pivoted brake shoes 16, 17 is fitted between wear members 39, 44 provided on the free ends of the shoes and having legs 42 extending on opposite sides of the cam provided with barrel-shaped portions 47, 50 adapted to engage the edges of the legs. The legs 42 are cut away on arcs of greater radii than the radii of the barrel-shaped portions 47, 50 of the cam which they engage and the lower legs are slightly spaced from the portion 50. An intermediate portion of the cam has shoulders 54 to support the cam normally on the wear members and to prevent wrong rotation. Cam portions 51 of the cam support and hold the cam on centre during operation. The part 43 of the wear members is slotted to receive the webs of the shoes and is secured by a single rivet 40. The brake shoe pivot member 14 is formed of hexagonal bar and fits in a hexagonal hole in a support member 12 riveted to the brake backing plate. The bottom of slots 15 in the member 14 are milled at an angle to the drum axis and the ends of the shoes received in the slots are formed upon similar angles so that rotation of a nut on the screened end of the member 14 adjusts the shoes to and from the drum. A spring- ball arranged in a transverse slot in the member 14 clicks against axial grooves in the thread on the interior of the nut to indicate the amount of adjustment. The webs of the shoes are cut away at 18 and the flange turned over to form rounded ends. An adjustable centralizing member 58 lies against the backing plate and has shoulders 61 bearing against the cylindrical flanges of the brake shoes. Securing bolts pass through slots 63, 65 arranged at an angle to one another in the member 58 and the backing plate respectively. A shoulder on each bolt is adapted to be passed through the slot 63 when assembling and engage the slot 65. A spring 74 is adapted to press the member 58 against the shoes when the bolts are slackened, and when the shoes have been forced against the drum by retracting the member 14, which is then adjusted to give the required clearance of the shoes. A device for preventing rattling comprises a spring 32 bent upon itself to engage both sides of the shoe web and held between a shoulder on a stud 30 and a cotter pin 34 passing through the stud. The stud is covered by the backing plate and passes through a slot in the shoe.

Dec. 3, 1930, No. 36515. Convention date, Dec. 3, 1929. [Class 40 (v).] In a tuned band-pass coupling, the coefficient of magnetic coupling between two tuned circuits is automatically varied from a maximum at low frequencies to a minimum at high frequencies by means of an element in which currents are induced in opposition to those creating the normal coupling flux. As shown in Fig. 1, the position of a ring-element 5 of aluminium, silver, copper, or other .lowresistance metal relatively to the coupling coils 2, 3 determines the effective magnetic coupling between the circuits 1, 2 and 3, 4. In Fig. 3, the ring 5 is split, and the two ends connected to a condenser 10, forming an absorption circuit in which the induced currents act in opposition to the normal coupling-flux. In Fig. 4 this arrangement is utilized at 51, 101 to maintain a constant band-width between coupling-circuits 14, 15, 16 and 18, 19, 20 of the band-pass type. It is also utilized at 5, 10 to provide a closer coupling between the aerial and the first amplifier stage at low frequencies than at high, in order to make the receiver equally sensitive throughout a wide frequency range. Ganged tuning-control may be used.

Abstract: 838,151. Spin-driers. A.E.I.- HOTPOINT Ltd., [formerly HOTPOINT ELECTRIC APPLIANCE CO. Ltd.]. Oct. 27, 1958 [Nov. 22, 1957], No. 36548/57. Class 34(2) [Also in Group XXXV] Braking of an electrically driven spindrier is effected through the end surface of the rotor moving downwardly into contact with a fixed friction surface. The shaft 5 of the spin basket mounts the rotor 6 such that it has limited axial movement between fixed collars 13, 14, through the interengagement between the rotor and the shaft of helical splines 12. When the motor-which is of the capacitor-start type-is switched off, the main winding or the start winding or both is/are shorted out and dynamic braking ensues, which, together with the normal tendency for the rotor to drop gravitationally causes the friction surface 17 of the rctor to contact the friction surface 16 carried by a resiliently mounted stationary brake member 15. On energizing the motor, the rotor rides up the shaft 5 to the collar 13 whereupon the drive is transmitted to the basket. When at rest the weight of the rotor may be taken by one or more springs 20.
