Title: Control arrangements for electric motor-driven machine tool spindles
IPC: B23Q5/18
Filed: 1948-11-17
Abstract: 652,196. Control of motors. HERBERT, Ltd., A., and LLOYD, A. H. Nov. 17, 1948, 'No. 29878. [Class 38 (iii)]  A machine too] of which the  spindle is driven by a variablespeed electric motor arranged tc be controlled by means of one of two or more electric speed-change devices, each of which has a dial or like rotatable member for pre-setting it, is provided with a single control member the operation of which selects that device which is rendered effective to control the motor. When the electric motor runs idly, dials A, B, C, may be adjusted in turn to operate the spindle at different speeds. A separate control element for the motor is associated with each dial and the element to be connected in the control circuit is selected by appropriately positioning a member 18 which carries suitable markings. The motor is coupled to a tachometer generator, the spindle-speed being shown on an indicator 16. Three different pre-determined speeds are thereby registered and can be introduced when required during operation of the machine by merely moving the member 18. The dials A and B may be calibrated for the same speed-range, the dial C having a lower range. The control elements regulated through dials A, B, C, may be variable resistors, potentiometers, or transformers. An electronic control unit may be provided. The member 18 may have a position for inching, a reversing lever 31 also being included. When two-speed or other multi-speed changespeed gearing is used between the motor and spindle, the dials A, B, C are calibrated in a corresponding number of ranges and the speed-indicator has a similar set of markings.

Abstract: 927,469. Plansifters. BUHLER GEB. Aug. 30, 1960 [Sept. 16, 1959], No. 29889/60. Class 117. The side walls 1 of a plansifter compartment provide guide ducts for the material being treated, and have vertically spaced pairs of rails 3 extending therealong on to each pair of which a sifter frame 4 is slid. Each frame includes a sieve mesh 5 and a coarse mesh 6 between which cleaning means such as balls &c. are accommodated. Each frame is grooved at 9 to slidably receive the tongues 12 of a further frame 10 or 19 which is urged against the sifter frame by springs 14. The latter are secured to the frame 10 or 19 and contact the lower surfaces of a pair of rails. The frames 10 carry base-plates or collecting bottoms 11 over which material passes laterally to the guide ducts, whereas the frames 19 serve merely as spacers. The plates 11 include handles 16 to facilitate their removal. Sealing strips 8 and 13 on the frames 4, 10 and 19 avoid the formation of gaps or dead spaces in which material may be deposited. Instead of leaf-springs 14, tapered projections may be located on the frames 10 and 19, with coverings of plush &c., which engage with the undersides of the rails. Specification 818,579 is referred to.

Title: Improvements relating to locks
IPC: E05B63/20
Filed: 1947-11-10
Abstract: 637,558. Locks. STERNER, B. Nov. 10, 1947, No. 29909. [ Class 44]  A lock is provided with means whereby the bolt, when retracted by a key or operating knob, is automatically retained in a position projecting slightly from the casing, but is movable into a non-projecting position, and can be moved into fully projecting position only by the application of pressure to the projecting end, and means whereby, when pressure is applied to the projecting end, further projection may be prevented so that the bolt may act as a spring catch. The base plate 1 has a projecting boss 9 which fits into an aperture bored in the door and accommodating also a barrel lock 6. The cover 2 slidably engages the base plate after the latter is fixed and is secured by screws through flange 17 on the edge of the door. The striking plate 4 is secured by screws 19, 21 which are inaccessible when the door is closed, and the end 35 of the lock cover projects over the edge of the striking plate to impede the use of a tool to force the bolt. The mechanism comprises a sliding plate 3, Fig. 5, from which extend two cylindrical bolts 22, slightly bevelled on each side, a spring 24, and a pawl 28 pivoted to the tail of the plate 3 and spring urged so that its outer edge is normally in line with the edge of the plate. The bolt is operated by a knob 40, Fig. 3, keyed to a follower 31 which has an arcuate surface 32 with a notch 33 at one end. When the bolt is in the shot position, notch 33 lies adjacent to a rib 60 on plate 3. On turning the knob to retract the bolt (clockwise as seen in Fig. 5) the follower makes contact with pawl 28, which, at the position shown, is pushed outwardly to engage against the edge of a gap 34 in the casing, and the bolt is held in this position on release of the knob. Pressure on the nose of the bolt will however release the pawl and allow it, urged by its spring, to move out of gap 34, thus allowing the bolt to shoot fully. In order to allow the bolt, when in the retracted position of Fig. 5 to act as a spring catch, a catch 55, Fig. 3, is. provided which is connected to a member 56 ; the latter abuts a wall of the plate 3 when turned out of its normal position, so restricting movement of the bolt.

Patent GB-304536-A (GB)
Abstract: 304,536. Sundelin, U., and Granzelius, K.. A. T. Oct. 24, 1927. Divided on 280,186, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 3, 1927. Checking, recording, and registering receipts, with money-manipulating apparatus.-Sums of money received and disbursements made are registered and checked by means of a known computing-machine controlled by electric circuits under the action of inserted coins and manipulative devices. The invention is illustrated as applied to inter alia ordinary purchases with change-giving. A ccin when inserted closes in succession two contacts. The first of these energizes a magnet to set up the value on the keyboard and the second completes circuit to magnet 169 to enter the value in the machine. The handle 170 is then pulled to complete circuits at 173 - - 176. The first circuit depresses the print key 183 and the second and third operate the machine and print the sum on a voucher. The final contact at 176 depresses the key 192 to put the machine in the subtractive condition. The amount of the purchase is now set up manually by means of the keys the units being set up last. Depression of the units key makes a contact at 193 to energize a magnet 196 to operate a switch 199. Closure of circuits by this switch operates the machine through magnet 169 and, by means of the magnet 187, prints the sum on the voucher. Further circuits are then made by the switch to set the machine for printing, to connect the coin-delivering mechanism with the totalizer wheels, to operate the machine and finally to clear it. The mechanism whereby the balance left on the totalizer wheels is converted into change is shown in Fig. 3. For each denomination a rack 241 is moved under control of the totalizer wheel and in its movement operates a wheel 240 which in turn rocks a lever 236 to eject one or more coins. The engagement of the wheel 240 with the rack is controlled by a magnet 214 in one of the circuits closed by the switch 199 as stated above.

Title: Direct current magnetic amplifier systems
IPC: H03F9/04
Filed: 1959-09-08
Abstract: 869,488. Magnetic amplifiers. FOXBORO CO. Sept. 8, 1959 [Sept. 15, 1958], No. 30674/59. Class 40 (9). The input circuit of a magnetic amplifier receives an input signal which does not fall below a given minimum and biases this minimum to provide zero control current at this point, a bias being applied to the amplifier to restore the given minimum at the output. The arrangement acts as a variable ratio transformer in which both input and output rise from the same value. As shown, the input is applied to terminals 32 appearing across resistor 33. A resistor 35 takes a constant current from a voltage regulated source including Zener diode 37 and provides a bias equal to the minimum input signal voltage appearing across 33 so that under this condition no signal is applied to the input windings 28 of a first auto-self-excited full-wave magnetic amplifier. A variable resistor 34 enables the gain to be varied from input to output ratios of 3 to 1 to 1 to 3. Temperature compensating resistors 28<SP>1</SP> are included in the input circuit. A bias winding 31 provides an output from the second stage magnetic amplifier equal to the minimum input. The whole of the output current of the second stage is fed back in series with the load 40 to windings 29 on the first stage. Negative rate feed-back is applied to winding 29<SP>1</SP> on the second stage. Each stage has a short-circuit winding 27, 27<SP>1</SP>.
