Title: Apparatus for the manufacture of dry cells
IPC: H01M6/08
Filed: 1931-06-12
Abstract: 389,453. Assembling force fits ; soldering. BUMKE GES., H. A., 8, Chausseestrasse, and AUTOM-SPEZIAL-MASCHINEN GES., 5, B³lowstrasse, both in Berlin. June 12, 1931, No. 17055. Convention date, July 22, 1930. Void [Published under Sect. 91 of the Acts]. [Classes 83 (ii) and 83 (iv).] Making hollow-ware.-A machine for making dry batteries comprises a device for capping the carbon rods in combination with one or more devices for automatically effecting other operations such as soldering wires to the batteries and applying the covers. Fig. 1 shows a machine with devices II, III, IV for centring the batteries, punching out the covers and placing them in position. The cells are then conveyed to the capping device V and finally to a rotating conveyer 11 which brings them to the soldering device. The capping device consists as shown in Fig. 2 of a receptacle 135 for holding loose caps, and a sorting device 136 which feeds the caps to a channel 137 which brings them in front of a stamp 138. A second stamp 145 moves the cells towards the stamp 138 which forces the caps on to the carbon rods. The capped cells are then transferred in pairs by plungers 8, Fig. 1, to a rotating disc 11 which brings them to the soldering apparatus. The soldering apparatus comprises a pair of funnels 209, Fig. 6, provided with wicks soaked in soldering spirit, which are lowered at intervals into contact with the cells. The wetted cells are then carried by the disc 11 to the apparatus shown in Fig. 5, which brings into position and cuts off the required length of wire to be soldered to the cells. The wire 215 is fed from a reel and is seized by nippers 218 which rock eccentrically and reciprocate to and from the disc 11. The nippers carry the wire forward but open on their backward movement and leave the wire in its advanced position. The front end of the wire is guided and prevented from dropping by slides 221 the upper ends of which are slotted to receive the wire. These slides can move vertically in recesses in the disc 11 and are raised to engage the wire by means of cams 222. The apparatus for moving the wire 215 is duplicated so that two lengths of wire are advanced simultaneously. The required length is then cut from each wire by knives 224 and the disc 11 moves again to bring the cells to the soldering device, Fig. 7. This is provided with means for bringing forward the solder wire 225 similar to the wire-advancing device shown in Fig. 5. The solder wire is advanced in two lengths by nippers 227, the ends of the wire being brought beneath a pair of soldering-irons 230 which may be heated by gas or electricity. The irons descend and melt the projecting ends of the wire. Further descent of the irons brings them into contact with the cells and the wires 215 which are held in the correct position by the slides 221.

Title: A method of rendering the surface of a transparent body non-reflecting
Filed: 1938-06-09
Abstract: 519,768. Transparent sheets: SIEMENS BROS. & CO., Ltd., and GACHET, E. J. June 9, 1938, No. 17168. [Class 20 (iii)] A method of restoring transparency to a transparent body which has been rendered translucent by a roughening process, consists in applying to the roughened surface a transparent substance 'to form a hard and durable coating, the thickness of the coating being sufficient only partly to fill the pits of the roughened surface. The refractive index of the transparent substance is similar or near to that of the transparent body. As examples, nitrocellulose lacquer or transparent white varnish is applied to the roughened surface by painting or spraying. The coating is reduced to a very thin film near its edges to reduce the liability of peeling off.

Title: Improvements in or relating to pick-ups
IPC: H04R17/06
Filed: 1959-05-20
Abstract: 919,488. Gramophone pick-ups. DE VRIES, M. May 20, 1959 [May 27, 1958], No. 17175/59. Class 40 (4). In a turnover pick-up cartridge in which the points of the respective styli have different radii, each stylus is operatively coupled to both of two identical piezo-electric transducers. Either stylus of the pick-up may be used for lateral cut, hill-and-dale, or 45/45 two-channel stereophonic records by making suitable connections between the output leads of the two transducers. Two crystal elements 6, 7 (Fig. 2) are clamped in the casing 1, 2 (Fig. 1) by blocks of resilient synthetic material 8, 9 (Fig. 2), contact strips 10 to 13 leading to terminal pins 14 to 17, respectively. The free ends of the elements 6, 7 are connected to the two styli by a coupling device 18 consisting of one piece of visco-elastic synthetic material which includes two sleeves 21 and 22 and eight arms 23 to 30, of which arms 23 and 28 are connected at their merging point to sleeve 21, and arms 25 and 30 to sleeve 22. The free ends of the elements 6, 7 are located in slot-like openings 31, 32 in sleeves 21 and 22, respectively. The stylus holder 19 (Fig. 1) bears against the connecting piece 33 (Fig. 2) between arms 24 and 26, and the second stylus holder (not shown) against the connecting piece 34 between arms 27 and 29. Operation with 45/45 record (Fig. 3).-One set of signals vibrates the stylus in the direction 36 resulting in twisting of element 6 but substantially no twisting of element 7, while the other set vibrates the stylus in direction 38 resulting in twisting of element 7 but substantially no twisting of element 6. The outputs are taken from terminal pins 14, 15 and 16, 17 (Fig. 1), respectively. Operation with lateral cut record (Fig. 4).-The stylus is vibrated in the horizontal direction as indicated at 40 and the two elements 6, 7 are twisted as shown by the full lines 41, 42, the outputs being connected in series aiding. Vertical movements of the stylus produced by the pinch effect or by irregularities in the record or turntable will result in twisting of the elements 6, 7 in opposite directions as indicated by the dashed lines 44, 45 and the outputs produced in response to these movements will be in series opposition and will cancel out. Operation with hill-and-dale record.-In this case the connections between the outputs are changed so that the voltages caused by the vertical movements of the stylus are added, and those caused by the horizontal movements cancel out.

Title: Improvements in course recording apparatus
IPC: G01C17/00
Filed: 1918-10-22
Abstract: 144,740. Logan, M. B. Oct. 22, 1918. Indicators, speed.-A velocity in a plane is measured by integrating the accelerations in two directions at right angles, communicating the component velocities to a distant station and there compounding them. The movements of two weights, due to variation of the velocity of the aeroplane &c., on which they are mounted, are caused to move two friction disks over a uniformly driven disk, and the velocities of the friction disks are electrically transmitted to a receiving apparatus by which they are combined to indicate speed and to record the course upon a chart. The two weights move in directions mutually at right angles, and are mounted on a frame suspended in gimbals in which a gyroscope is also mounted. The gyroscope 11, Fig. 1, is mounted in gimbals, 1, 2, which also support a motor 5, preferably of the synchronous alternating current type, which drives a disk 6. The disk 6 has a toothed rim and, through the gearing 7, 9 drives the axle 10 of the gyroscope 11, the gearing being mounted in a frame 12 rotatable about the axis of the disk 6. The upper part of the frame 12 is formed as a ring 13, rotatable within a fixed frame 14 so that the axle 10 can be set to any desired position in azimuth. The friction disks 17 are mounted over a disk 6 in planes at right angles to each other on square spindles 18 secured to the rotors of alternating-current generators 19. The actuating weights 20 are of true spherical form and are adapted to roll along rails 21. They are mounted in cages 26 to which are secured forks 25 adapted to move the disks 17 along their spindles. Cords 27 connected to the cages 26 pass over wheels 28 containing springs. The receiving apparatus, Fig. 4, contains two disks 29, 30, driven by a motor 31, and over these disks are mounted friction disks 34, 34a on square spindles 33. Each friction disk is adapted to be moved along its spindle by a fork 35 secured to a nut 26 on a screw 37, which is secured to the rotor of a motor 38. The rotors of the motors are connected to the primary source which drives the motor 5 &c. and the stators are connected to the corresponding generators 19. The disk 34 is connected by gearing 39 to the screw 40 on which is a nut 41 carrying the scriber arm 42, while the disk 34a is connected by gearing 43, 44, 46 to the roller 47 which traverses the chart 48 beneath the scriber. In order to indicate the speed of the aeroplane &c. one of the motors 38 drives a screw 50 which passes through a broad-faced gear wheel 51 so as to move it longitudinally without rotating it. The second motor 38 drives a screw 55 passing through a rack 54 adapted to revolve the wheel 51. The wheel 51 carries a housing 52 through which moves a rack 53 carrying at its end E a cord 56 passing through a hole in the guide 57 and thence to a pulley 58 after which it passes round a spindle carrying a pointer moving over a suitable scale, a spring being provided to maintain the cord in tension.

Abstract: 1,168,792. Mine roof supports. K. M. GROETSCHEL. 21 April, 1966 [21 April, 1965], No. 17405/66. Headings E1E and E1P. In a mine-roof support, a portion of flexible mat 19, 18 is stored on a moving means and a portion is led off supported adjacent the roof 15 and underpinned at intervals along its length. The mat, which may be of woven or slat material, is carried in a roll 18 on a spindle 16 rigid with a coal mining machine 10 moving on conveyor runway 13. After anchoring at one end, the mat is fed out over a roller 20 to the roof and is supported by advancing long beam 48. The mat may be secured to the roof by cement or other quick setting adhesive. A self-advancing support, used with the invention, comprises a base 35 having a single hydraulic prop 38 supporting the rear end of a superstructure 44 and a multi-section prop 37 having a yoke 42 supporting the forward end of the superstructure. The base 35 is coupled by an advancing jack 59 to the conveyer 13. The long beam 48 is supported on the inner section 40 of the prop 37 through a shoe 53, the long beam being advanced relative to the shoe and superstructure by a jack 58 or by adjustable packing means. The forward end of the long beam is pre-loaded by leaf springs 73 anchored to a cross piece 47 rigid with the superstructure 44. The rear end of the long beam is carried in a hollow member 62 in pin 65 and slot 64 connection with the long beam and adjustable longitudinally by a jack 66 connected to a cross-member 51 joining the two roof bars of the long beam. Additional pressure on the forward end of the long beam is supplied by short jacks 70 between the beam and the superstructure to tilt the long beam. The long beam may be curved to bear hollow at its central portion and may have a universally pivotted forward roof engaging plate or a jack operated extension 75 to support a part of the roof exposed by a scarped fall. The rear of the long beam may be positioned between the roof bars of the superstructure by spring-loaded or manually clamped transverse pins. In another embodiment, the long beam is loaded at its forward roof engaging end by a jack between the beam and the base 35; the beam may be supported from the base by leaf springs to prevent misalignment on sloping seams or two loading jacks may be used. The rear end of the long beam may be supported by a spring retracted hydraulic prop to allow advancing of the base and superstructure props; the supporting prop being supported by leaf springs to compensate for sloping seams. A further embodiment utilizes a separate prop in place of the inner section of the multi-section prop and advancing is carried out by a jack between the base 35 and the base of the separate prop. The long beam may be supported by both cantilever springs and by a diagonal jack between the base and a cantilever beam pivotted to the forepart of the superstructure. Additionally the superstructure may have forepoling arms.

Title: Arrangement for measuring and weighing bins in skip hoisting installations
IPC: B65G47/19
Filed: 1953-06-23
Abstract: 741,691. Weighing apparatus fitted to skip hoisting installations. SKIP COMPAGNIE GES. June 23, 1953 [June 23, 1952], No. 17420/53. Class 143 In a skip hoisting installation for coal or other mine shafts the skips are fed by two measuring and weighing bins 1, 1a of rectangular structure suspended from a common weighing beam 2 for balancing the dead weight of the bins. As shown, the bins are supported in frames suspended from the beam 2 by universal joints, 7, 7a and after filling are each alternately rocked by pneumatic rams 10 to discharge into an associated one of a pair of laterally arranged skips 9. Closure slides 8 at the base of the bins are rocked with the bins and travel on rollers r, but after the supply edge of the skip is reached an abutment stops the closure slide 8 so that the further rocking movement of the bin uncovers its outlet. The bin frames are, however, prevented from outward movement by pivoted rods 11, 11a. Arrival of a skip at a filling station is arranged through a switch and timing relay to initiate rocking of the associated already filled bin. Filling of the skip then actuates a switch to restart the skip conveyer. The upward rise of the emptied bin then releases a counterweighted lever 4 controlling a switch actuating an associated one of two conveyer belts 12 so that filling of the empty bin recommences from the storage hopper 13 until the weighing beam again reaches equilibrium. In a modification each end of the weigh beam 2 acts on hydraulic pressure gauges controlling the belt conveyers 12. After each control switch is actuated by the weighbeam it is further arranged that the belts 12 are not driven until a skip has reached the filling position and actuated a switch.
