Title: Improvements in the grouping of cut bricks or the like from column or stream extrusion mechanisms
IPC: B65G49/08
Filed: 1935-01-15
Abstract: 450,172. Cutting and grouping bricks &c. FREY, E., 64, Loestrasse, Chur, Switzerland. Jan. 15, 1935, No. 1304. [Class 87 (ii)] A device for grouping bricks &c. cut from an extruded column comprises a frame 16 on the discharge side of the machine which is positively moved forward with the column at the beginning of a grouping operation and is afterwards moved backwards while a movable depositing plate 19 mounted on the frame receives an additional forward movement relative to the frame to perform the grouping. The cutting mechanism comprises a carriage 1 operated from a driving shaft 15 controlled by the speed of the clay column 9 and operates as described in Specification 450,171. The frame 16 runs on rollers 17 and is reciprocated by a lever 33 from a cam 36 on the shaft 15. The supporting plate 19 is pivoted on a shaft 18 adapted to slide in a slot 20 and is rocked by a bolt 30 working in an angular slot 31 and operated by link mechanism 26 from a cam 21. In operation, a plate 38 receives the bricks from the cutting mechanism and, while the frame 16 is moving forward with the clay column, the plate 19 is first tilted and then moved forward in the slots 20, 31. When the plate 19 comes to rest the bricks 42-44 continue to slide forward thereon thus increasing their separation from the main column. The plate 19 then returns to its horizontal position and the frame 16 is moved backwards to receive a fresh group of bricks. The shaft 41 is driven from the shaft 15 through gear wheels 22, 23 the ratio of which depends on the number of bricks in a group. When there are four cutting wires and the bricks are grouped in threes, as shown, the ratio of the gear wheels is 4 : 3. If the groups contain four bricks the frame 16 can be combined with the carriage 1 and the driving mechanism 33 can be dispensed with. Specification 174,414, [Class 87 (ii)], is referred to.

Title: A device for measuring the rate of increase of an integrated quantity
IPC: G01K17/12
Filed: 1949-01-17
Abstract: 662,770. Indicating-apparatus; integrating- apparatus. LANDIS & GYR SOC. ANON. Jan. 17, 1949 [Jan. 21, 1948], No. 1310/49. Class 106 (iv). [Also in Group XX] The invention comprises apparatus whereby the rate of increase of an integrated quantity may be derived from an impulse integration of physical magnitudes. The arrangement, may, for example, derive the instantaneous thermal output or efficiency of a heating system from an integrating mechanism registering the total heat output. Impulses from the integrating mechanism and from an auxiliary source each act on a differential gear coupled to a pointer so that the integrating mechanism tends to turn the pointer in one direction and the auxiliary source tends to turn it in the other, the resultant position of the pointer indicating the desired instantaneous value and determining the duration of the auxiliary impulses. The planet wheel 8 of a differential gear D is connected through a worm 9 to the pointer 22. One sun wheel 5 of the differential gear is connected to the integrating mechanism whilst the other sun wheel 6 is connected to the auxiliary source of impulses, the two sun wheels acting on the planet wheel 8 to turn the pointer 22 in the manner described. The auxiliary impulses originate from a shaped disc 25 rotated by a constant speed motor 26. The disc 25 bears against a stud 24 on the pointer 22, for a period during each revolution of the disc that is dependent upon the position of the pointer, to complete a circuit energizing a magnet 20, which magnet 20 controls a clutch 11, 12 through which the said auxiliary impulses are transmitted to the differential gear D from a constant speed motor 14. The integrated quantity is read on a counter 4. Specification 612,841 is referred to.

Abstract: 921,856. Coin-freed vending apparatus. AUTOMATIC CANTEEN CO. OF AMERICA. Jan. 16, 1962 [Feb. 20, 1961], No.1513/62. Class 27. Cylindrical articles, such as bottles 22, are stored in two staggered stacks in a compartment 10 and are released one at a time by the alternate inward movement of one or other of a pair of abutments 42, 44 which are carried by arms 50, 52 pivoted at 54. Rollers 56 on the arms co-operate with a disc cam 46 and in the position shown in Fig. 1 both rollers are in contact with the concentric portion of the cam and both abutments are in blocking position, the abutment 42 supporting both stacks. As the cam rotates, the left-hand roller 56 moves into the cam recess (see Fig. 3) and the abutment 42 moves inward, allowing the lowermost bottle to fall past it. The right-hand stack has meanwhile descended so that the lowermost bottle rests on the abutment 44 and the cam rotates further to complete 180 degrees and restore the abutment 42 to blocking position. On the next 180 degrees rotation, the abutment 44 moves inward to release the next bottle. The side and end walls of the compartment are adjustable to suit different articles and, for bottles, a plate with slots 28 guides the necks. Several compartments may be mounted sideby-side or end-to-end and the cams are then geared together and set at different angular relationships on their shafts so that delivery takes place from the compartments in succession. A coin-closed switch and solenoid relays activate a motor for driving the cams and a lock-bar solenoid is energized when a selector pushbutton is pressed, thus locking out the other selectors. Sold-out switches are operated by a feeler which enters an empty compartment.

Title: Improvements in expanding wheels and other rotary members
IPC: B24B47/18
Filed: 1936-09-09
Abstract: 481,423. Grinding machines. DUDLEY, W., and MORRIS, B. O. Sept. 9, 1936, No. 1565/38. Divided out of 481.362. [Class 60] In a grinding-machine wherein the spindle of the grinding wheel 11 is driven through variable-speed gearing, a stop member is interconnected by electrical means with the gearing so that said member must be adjusted before the spindle can be rotated at increased speed, such adjustment being prevented by contact of the member with the periphery of the wheel 11 unless the state of wear of the latter is sufficient to justify the increase of speed. 'The -speed gear shown in Fig. 1 includes an expanding pulley 12 driving the spindle through a belt 13, the rim of the pulley being constituted by spaced tread bars adapted to be moved towards or away from the axis. A contact member 40 actuated by movement of the work rest or holder 18 co-operates with a series of studs 39, each of which is electrically connected to a corresponding stud 37 of another series co-operating with a contact arm 36 linked to a slidable member 26. The members 36. 40 are connected in the circuit of the motor driving the pulley 12 so that, if one of them is moved without the other, the motor stops. The member 26 carries a part 24 formed with a lug 29 disposed outside the orbit of the projecting ends 17 of the pulley tread bars. Thus, as the member 26 is moved to the left by operation of the arm 36 following a movement of the rest 18 towards the wheel 11, consequent on wear of the latter, the lug 29 allows the diameter of the pulley to be increased only by a corresponding amount. A second lug 28 is formed on the member 24 inside the orbit of the bar ends 17 to prevent movement of the member 26 without corresponding adjustment of the pulley. An electric circuit including a signal device may be completed when the bar ends 17 contact with either of the lugs 28 and 29. Alternatively, the member 24 may, as shown, be pivoted on the member 26, a toggle spring 31 normally holding the member 24 in the position shown relative to the member 26, so as to hold electric contacts 32 and 33, connected in the circuit of the motor, in engagement. If either of the lugs 28 or 29 is struck by the bar ends 17, the member 24 is knocked up, separating the contacts and thus stopping the motor. In a form wherein the pulley can be adjusted while running by means of a fork, the latter is coupled to one contact arm while the rest is linked to a second contact arm. Where a group of machines are employed, the contact devices 56, 57 of the various machines may be arranged in series, as shown in Fig. 4, but each is shunted by a signal lamp 61. Thus, if an attempt is made to operate any machuie ineorrectly, the corresponding lamp lights up. The circuit also includes a lamp 62 which is normally lit but which dims when one of the lamps 61 is lit. Specification 481,362 is referred to. The Provisional Specification includes an arrangement in which a member corresponding to the part 24 is mechanically connected to the work rest.

Class 60 A honing tool, Figs. 1 and 2, comprises a body the front part 2 of which is provided with grooves 27 in which are arranged radially movable shoes 10 carrying honing stones 11 and collapsed by garter springs 12. The rear part 4 of the body is secured to the front part 2 by an adapter sleeve 3, and is coupled by a pin 14 to the head 15 of the drive element. The shoes 10 bear against cams 19 on the front part 18 of an adjusting shaft 1. A nut 9, having holes 26 to receive a wrench; is mounted on the threaded end 22 of the shaft 1. The axial movement of the nut 9 resulting from its rotation is transmitted through a thrust ball bearing 7 to a sleeve 6 formed as a nut to engage a coarse thread 23 on the adapter sleeve 3 so that the axial movement of the sleeve 6 causes its rotation and thus, through key 8, rotation of the shaft 1, so that the cams 19 adjust the stones 11. Axial movement of the sleeve 6 is limited by a nut 5 on a threaded part 24 of the adapter sleeve 3. The adjusting nut 9 and limit nut 5 can be manipulated through slots 28 in the part 4; a scale may be provided on the limit nut 5. In a modification, Fig. 5, rotation of a nut 41 threaded on part 33 of the adjusting shaft 31 causes it to move axially, this movement being transmitted to a member 37 having oblique slots 40 engaged by pins 39 on the shank 45 of the tool body 46 so that the member 37 rotates and through a key 38 rotates the adjusting shaft 31. Axial movement of the sleeve 37 is limited by nuts 42, 43 on threaded part 44 of the tool body; the sleeve 37 carries a scale.

Abstract: 1371395 Calibrating magnetic compasses SPERRY RAND CORP 14 Jan 1972 [26 Jan 1971] 1830/72 Heading G1N A fluxgate compass mounted in an aircraft is calibrated by deriving repsective output signals for each of two approximately opposite headings, combining the output signals to obtain a first resultant signal imposing on the fluxgate an excitation equivalent to a selected swing heading, combining the new output signal with a signal representing the expected output signal for the selected swing heading and with the first resultant signal to produce a second resultant signal, and adjusting the new output signal to minimise the second resultant signal thereby compensating for deviation error. First heading. The aircraft is placed (approximately) on a first heading line marked on the ground and the calibrator connected to the aircrafts altitude and heading reference set. Contacts A and C are open, contacts B closed. On pressing, a READ switch 15, the output of the fluxgate 2, represented as longitudinal and transverse components, is stored in memory 14. The misalignment of the aircraft is measured (as the difference between the lateral distances of two points on the aircraft from the line) and set by hand on a potentiometer 5 and is also stored in memory 14. Second heading. The aircraft is rotated through 180 degrees and aligned with a second heading line such that the fluxgate 2 is above the same ground location. The misalignment is again set at 5. On pressing the READ switch 15, data processor 10 subtracts the output of the fluxgate from the stored first heading output signal and the resultant "earth's field cancelling" signal is rotated through half the difference of the misalignment angles for the two headings. Swing. Contacts A, B and C are all closed. The co-ordinates of the earth's field for the aircraft's actual heading are sent to sample and hold circuit 12. A desired swing heading is set by hand on selector 23 and the co-ordinates of the swing heading field are sent to sample and hold circuit 24. In current servo 8 the output of sample and hold circuit 12 effectively cancels the earth's field output of the fluxgate 2 and the output of sample and hold circuit 24 causes the fluxgate 2 to provide an output signal representative of the selected swing heading which is compared in data processor 10 with the selected heading. The sign and magnitude of the resulting error signal is displayed at 17. Compensation network 7 is now adjusted to minimise the displayed error signal. The calibrator is then returned to its normal condition (contacts A closed, contacts B and C open) and disconnected from the aircraft.

Abstract: 1,194,752. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 12 Jan., 1968 [16 Jan., 1967], No. 1861/68. Heading H1K. The collector region of a transistor is provided with a high conductivity buried collector layer underlying the active collector region comprising a thin portion under the base region and a thick portion under the collector contact, the portions being formed by diffusion of impurities, having relatively low and high diffusion constants respectively, from a substrate during the growth of an epitaxial layer. An NPN transistor is produced in a P-type silicon wafer (10) by diffusing arsenic into a rectangular region (11) on one face, diffusing phosphorus into two rectangular regions (12, 13) disposed at opposite ends of the arsenic doped region (11), Figs. 1 and 2 (not shown), etching the surface and depositing an epitaxial layer (20) of N-type silicon during which deposition the diffused regions (11, 12, 13) spread into both the wafer (10) and the epitaxial layer, Figs. 3 and 4 (not shown). Boron is then diffused into the surface to form a P-type base region (14), Fig. 5 (not shown), and phosphorus is diffused into the base region 14 to form the N-type emitter region 15 and into the collector region 20 to form the collector contact regions 16 and 17 which contact regions 12 and 13. The diffusions are performed using an oxide masking technique, and the epitaxial deposition may be either by vacuum evaporation or by reduction of silicon tetrachloride.
