Title: Improvements relating to cultivators
IPC: A01B35/22
Filed: 1929-09-20
Abstract: 340,244. Implements for working land. FERGUSON, H., 6, Donegall Square East, Belfast. Sept. 20, 1929, No. 28534. [Class 6 (i).] A pivoted cultivator tine of rigid type is controlled in such a manner that it rises automatically over obstructions and returns again to its working depth without stopping the implement, the arrangement being such that the resistance offered to the upward movement of the tine decreases progressively throughout that movement. A plurality of tine units are carried on an implement frame connected to a tractor by links. Each unit comprises two parallel bars 4 between which a tine 6 is pivoted about a point 6a. On encountering an obstruction the tine rises against a resistance communicated from a spring control by means of a lever and link mechanism comprising of a double link 7 pivoted at 6b to the tine 6, and at 7a to a double link 8 pivoted about a pin 8a. The link 8 carries at its lower end a stopper pin 8b which locates the tine in its working position so that its point 6c is in or about the same vertical plane as the pivot 6a. A single or double spring may be attached to the pivot 7a and to a fixed cross-pin at the other end of the bars 4, or in a rear tine the spring may be connected to the pivot 8b. This lever and link mechanism is so constructed and arranged that it ensures a maximum force on the tine in its working position and also that the resistance offered progressively decreases as the tine rises. Alternatively the spring control may be effected by means of a double bar 12, as shown, connected at one end to the pin 7a, and at the other to an end 13a of a rocker 13 pivoted about a pin 13b and having one end of a spring 11 attached to it. The degree of resistance can be varied by altering the offset from alignment of the centres 13a, 13b, 7a by suitable means such as a set-screw 16 passing through a cross-member on the double bar 12, and bearing on the rocker 13.

Title: Improvements in or relating to multiple breech mechanisms for engine starter devices
Inventor: CLEAVE EDGAR SHERVILLE
IPC: F02N13/00
Filed: 1948-11-04
Abstract: 650,604. Starting. PLESSEY CO., Ltd. Nov. 4, 1948, No. 28679. [Class 7(v)] [Also in Groups XII and XXI] To ensure a gas-tight seal for all the breeches of a multi-breech mechanism the sealing pads 11, which are to bear against the heads 25 of the several cartridges located in barrels 22, are moved axially to the operative position through a lost motion mechanism. Such mechanism ensures effective sealing in each breech irrespective of any irregularities in thickness in the heads of the cartridges. In the form shown a breech head 1 has six cavities 2 each housing a pad 11. Each pad can move axially but is prevented from rotation by a key 20, and each is threaded to carry a nut 13 which can rotate but cannot move axially. Each nut 13 is connected by a coil spring to gear 15, and all six gears 15 mesh with a gear wheel 7 which can be rotated by a handle 4. When the cartridges are in place and the parts are assembled the handle 4 is pushed inwards against spring action and is then rotated; these movements enable a pin 5 carried by the handle to move along the limbs of a slot in a ring 6 fixed to the head 1, and enable the pin to rotate the gear wheel 7. The resulting rotation of the nuts causes the pads to move to the sealing position the springs providing the required lost motion. A barrel plate 21 has upstanding studs which engage keyhole slots in a cover plate 19 of the head 1. thus enabling the head to become fixed to the barrels by a slight rotary movement.

Title: Improvements in mechanical lighters
IPC: F23Q2/14
Filed: 1949-11-10
Abstract: 670.221. Frictional lighters. BACHRACH, S. Nov. 10, 1949, No. 28854/49. Class 75(iii) [Also in Group XV] In an automatic pyrophoric lighter release of strained resilient means results in the fuel reservoir and wick tube carried thereby sliding relative to supporting means, so that a spark-producing member mounted to move with the reservoir and wick tube 5 which carries a tubular steel 7 ber on the supporting means as the wick tube is projected from the lighter. A reservoir 3, Fig. 1, slidably supported on a spring 22 in a tubular casing 1, carries a wick tubes which carries a tubular steel 7 near its upper end and which extends through a flint housing 11, 13 secured to the casing 1. The flint is in two parts 8, having concave faces which fit round the tube 5, and the edges of which are held against one another by springs 20. In an alternative construction the flint is mounted on the wick tube and the steel is placed in the housing 11, 13. In use a slidable clip 23 connected to a support 25 fixed on top of the reservoir 3 is pressed down to compress the spring 22 and to pull the steel 7 down to a position just below the flint 8 : on releasing the clip the spring 22 forces the steel 7 rapidly past the flint 8 to ignite the wick 6 before it reaches its original position again. In a modification, Fig. 7, the wick tube 5 is placed and held in its cocked position by pressing down a button 29, fixed to the reservoir 3, until a knob 34 on a resilient strip 32 also fixed to the reservoir engages a hole 35 in the casing ; the spring 22 being already compressed, operation is effected by pushing on a clip 37, so that its lower end 36 pushes the knob 34 out of the hole 35. In another modification, Fig. 8, diametrically opposed pins 38 on the wick tube 5 engage slots 39 in two arms 40, integral with a cap 42 and pivoted on a pin 41. In the inoperative position the spring 22 is compressed and the cap 42 is held closed by the engagement of the hooked end 46 of a resilient strip 47 with a projection 45 in the cap ; on pressing a button 48 secured to said strip, the spring 22 forces the wick tube 5 upwards, the cap 42 being simultaneously raised. In another construction, Fig. 10 (not shown) the lighter is similar to that shown in Fig. 7, but the button 29 is dispensed with, the clip being slidable as in Fig. 1, so that depression thereof serves to cock the parts ; the cap is pivoted as in Fig. 8, the parts 45, 47 being omitted. In a modification, Fig. 11 (not shown), the operating means are as in the last construction, but the cap is spring-urged to the closed position and the slotted arms 40 of the cap are replaced by curved arms bearing on stops on the wick tube 5 ; in operation the force of the spring 22 overcomes the cap spring. A lighter of the form shown in Fig. 1 may be combined with a pen, Figs. 13 to 16 (not shown).

Filed: 1964-07-13
Abstract: 1,066,884. Purifying signals. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 13, 1964 [July 13, 1963], No. 28886/64. Heading H3T. [Also in Division G4] Signals are freed from spurious components by passing them to the inputs of a differential amplifier in one case directly and in the other case via a voltage divider, rectifier and a storage element to produce a reference voltage (Fig. 1, not shown); the subtracted output from the differential amplifier comprises the desired signal. The voltage divider may be included in the first input to the differential amplifier instead of the second (Fig. 3, not shown). The invention is useful in cleaning up the signals obtained by the optical or capacitative scanning of markings on cards. In Fig. 5, the differential amplifier comprises a Schmitt trigger circuit Tr1 and Tr2, the input signal at a being fed to the base of Tr1 via level-restoring diode D2 and to the base of Tr2 via voltage divider R1-R2, diode D1 and storage capacitor C1. Noise signals which are insufficient to cause Tr1 to conduct are passed on to Tr2, C1 charging and discharging through R4, R5 and R6, but larger noise signals turn on Tr1 making the potential at d less negative and thus increasing the effective time constant of the circuit. C1 cannot then pass on rapid fluctuations due to noise but can transmit the signals which are of longer duration. Diode D3 exerts a further levelrestoring function.

Filed: 1945-10-31
Abstract: 600,641. Air cleaners. HOUDAILLEHERSHEY CORPORATION. Oct. 31, 1945, No. 28920. Convention date, Dec. 31, 1943. [Class 8 (ii)] In an air cleaner comprising a casing 10, 42 in which a filter container 24 is mounted above a sump 50 so as to define an air inlet passage 48, a projection 49 on the container extends into the passage and serves together with a deflector 46 at the inlet end of the passage to prevent inflowing air from following a straight path to the container. The deflector 46 comprises a lip which extends inwardly from the casing wall 45 as far as a bulge forming the projection 49 extends outwardly. Dirt-laden air is further deflected from the upper surface of a baffle 35 into the filter comprising curled cattle-tail hair, vegetable fibre or the like maintained in the container by sheets of hardware cloth 32, 26. A hollow bolt 8 by which the cleaner is secured to a gear box serves to vent the latter.

Abstract: 1,118,145. Trueing grinding wheels. ULVSUNDA VERKSTADER AB. 8 July, 1965 [8 July, 1964], No. 28984/65. Heading B3D. A method of sharpening a grinding disc 14 in a grinding machine by means of sharpening tool, such as a diamond tip, supported by a holder 12, the tool and the grinding disc prior to each grinding operation being reset relative to one another for a dressing operation, comprises sensing vibrations of the tool or holder, converting the vibrations into signals, and using the signals to indicate or adjust the dressing depth. The vibrations are sensed by a feeling or scanning member which produces an electronic potential from the vibrations of the diamond holder, the signal being proportional to the sharpening depth and corresponds to the resonant frequency or frequency of impacts of the grains of the grinding wheel. The signal passes through a filter 16, where unwanted impulses which have no bearing on the sharpening operation are filtered out, to an amplifier 18. The output from the amplifier passes to an indicator 20 and to two current relays 24, 25, one producing a signal when the deflections are too small and the other a signal when the deflections are too large, the signals controlling advance and retract members 26, 27 for controlling the sharpening depth.

IPC: H02P7/34
Filed: 1954-10-11
Abstract: 774,423. Exciting dynamo-electric machines. GENERAL ELECTRIC CO., Ltd. Oct. 11, 1955 [Oct. 11, 1954], No. 29256/54. Addition to 677,247. Class 35. [Also in Group XXXVII] A D.C. supply system comprises a main generator 10 having the field winding 12 fed from an exciter 13 whose excitation current is arranged to depend upon the main generator output power and current and upon a reference electrical quantity. The exciter 13 has a first field winding (not shown) which is supplied with direct current at variable value for the speed control of the motor 11, and a second winding 1 energized through a metal rectifier 2 in dependence upon the power and current output of the generator 10. The rectifier 2 is such that no current passes until a predetermined voltage is reached when a current flows in the winding 1 tending to reduce the excitation of the generator 10 and therefore limiting the output current. In order to energize the winding 1 in dependence upon the power output of the generator 10, an exciter 3 is provided and driven by the motor 11 and, therefore, runs at a speed proportional to the voltage of the generator 10. The field winding 15 of the exciter 3 is supplied from across the generator interpole 14 and therefore in proportion to the generator current; hence output power of the exciter 3 is proportional to the output power of the generator 10. Rectifiers 4, 5 are arranged to enable the current and power supplies to the winding 1, while rectifiers 6, 7, 8 deal with regenerative conditions when current in the generator 10 and motor 11 circuit reverses. If the motor 11. is required to run at various speeds by control of its field, then a separate motor supplied from the generator 10 is arranged to drive the exciter 3. Instead of using a single winding 1 of the exciter 13 to provide both for current and power limit control of the generator 10, two separate field windings may be provided on this exciter in addition to the winding whose current depends upon the reference electrical quantity.
