Abstract: 660,553. Batteries. BURNDEPT, Ltd., and RICHARDSON, R. P. Oct. 21, 1947 [June 25, 1945], No. 16165/45. Class 53. [Also in Group XXX] Dry batteries of the layer type are made by first stamping out the zinc cups and then placing them on the platform 7 of the apparatus shown in Fig. 6 and in plan in Fig. 8, which delivers them upside down into carriers 19 which are placed manually on a conveyer 16. The cups are placed mouth upwards on the platform 7 which has a sloping portion down which the cups slide towards a number of tubular or covered shoots 8 at the upper ends of which are rollers 11 which pass the cups singly down the shoots. The rollers 11 are rotated continuously through gearing from a motor 14. The shoots are curved backwards at their lower ends and the cups are therefore inverted when they reach the lower ends of the shoots where they are arrested by loaded hinged stops 13 until picked up by the carriers 19. Fig. 5 shows in section one of the carriers which consists of a frame 2 having a number of V-shaped members 3 for supporting the inverted cups 4. Side members 5 are provided with lugs 6 by which the carrier can be supported in a centrifuge. The conveyer on which the carriers are placed comprises two parallel chains 16 having lugs 18 which sweep over two fixed rails 17. The filled carriers are passed through a station where the bottom surfaces of the cups are coated with the material forming the positive electrodes of the cells. The coating operation may be performed by pouring over the outer surfaces of the cups a suspension of finely-divided carbon in a liquid consisting of drying oils and a dissolved plastic. The carrier with the coated cups is then placed in a centrifuge to remove excess liquid and is then removed and placed on a conveyer and passed through a drier. In order to present the cups mouth upwards to enable the cells to be completed a tray 21 having ribs 22 is placed over the cups in the carrier as shown in Fig. 5 and the carrier is then turned upside down and removed leaving the cups standing in rows on the tray from which they can be fed in single file to apparatus for completing the assembly of the cells. Specifications 579,986, 642,361 and 660,554 are referred to.

Title: Colorimeter
Inventor: SOMKUTI ADOLF
IPC: G01J3/51
Filed: 1964-04-20
Abstract: 1,063,023. Photo-electric colorimeters. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENTYTARSASAG. April 20, 1964, No. 16290/64. Heading G1A. A colorimeter for the direct reading of the chromaticity co-ordinates, or deviations from predetermined co-ordinates, has at least three colour filters and one or more photo-electric detectors and utilizes separate arrangements of variable resistances for reading each chromaticity co-ordinate. The colorimeter may be used in checking the chromaticities of fluorescent lamps and includes three photo-cells X, Y, Z e.g. selenium cells each arranged to have a specific spectral sensitivity by use of a corresponding colour filter, which may be coloured glass or an interference filter wedge. The photo-cells can be switched individually, or all three together, into the colorimeter circuit by means of a fourway switch 11. In position I, for example, cell X is connected to the slide contacts of its particular arrangement of variable resistors 13, 14 while in position IV, all three cells are connected to the common end points of the resistance arrangements. Initial zeroing of the centre-zero galvanometer 21 is accomplished with the switch in position IV, by balancing the total current from the cells with the auxiliary current from a battery 19, by adjustment of variable resistor 20. Thus when any one of the cells is switched into circuit, the galvanometer is rezeroed by movement of the sliders along the particular resistance arrangement. The particular chromaticity co-ordinate is read off as the ratio of the resistance between the slide points to the resistance between the end points of the resistance arrangement. The coordinate Values may be preset on the variable resistance by previous positioning of the sliders, and deviations from these values read off as deflections of the galvanometer which has previously been calibrated. Further variable resistance arrangements are possible e.g. Fig. 3 (not shown). Various exemplary values for the variable resistances, which may be banks of equal resistors, are given.

Filed: 1956-05-28
Abstract: 789,364. Thread grinding. LINDNER, GES., H. May 28, 1956 [May 28, 1955], No. 16487/56. Class 60. [Also in Group XXII] Means for correcting pitch error in the lead screw of a thread-cutting machine, particularly a thread-grinding machine, comprises a differential gear for varying the rotation of the lead screw, under the control of two correcting arms, one for one flank of the screw and the other for the other flank of the screw, the control correcting arms becoming automatically alternatively effective according to the direction of rotation of the screw, so that correction takes place in both directions of movement. The lead screw 1 is driven from the work spindle through interchangeable gears, of which the final gear 2 is shown, and a differential gear 4. The drum 7 of the differential gear 4 has a worm wheel 14 in mesh with a non-self-locking worm 15 of steep pitch on a shaft 16 carrying a gear 17. The latter meshes with rack teeth on plungers 18, 19 carrying at their lower ends rollers 25, 26 cooperating with correcting arms 27, 28 on a support 29 secured to the machine bed 30. The differential casing 12 is secured to the carriage 13 which is supported on the bed 30 by rollers 31, 32, 33. For one direction of rotation of the lead screw 1, e.g. for the forward stroke of the carriage, the reaction of the differential drum 7 causes one plunger to be depressed so that its roller co-operates with the corresponding correcting arm ; when the direction of rotation of the lead screw 1 is reversed for the return stroke of the carriage, the opposite reaction of the differential drum causes the other plunger to become operative.

Abstract: 204,096. Siemens Bros. &. Co., Ltd., and Turner, F. June 16, 1922. Dynamomete,r,s, rotary-transmission.-In apparatus of the kind in which the torsion produced between two points in the length of the shaft imparts deviation to a beam of light, fouw reflecting mirrors, and a scale movable concentrically to the shaft are used which enable measurements of the torque to be made for any position of the shaft in its revolution. The adjacent flanges a, b are connected to the shaft at points some distance apart, the former carrying pivoted to it mirrors d and f each of which has two reflecting surfaces arranged back to back. The flange b is connected to the mirrors d, f by spring arms e, h so arranged' that when relative movement between the flanges occurs the mirrors d, f are turned in opposite directions. A scale box 7 has fixed to it a holder 6 for a lamp 5 and is mounted so as to be movable through ninety degrees along the quadrant 8. Consider the mirror d with reflecting surfaces A, A<1>. When light is rejected' from the surface A, Fig. 1, a spot of light will be formed on the scale 10 in Fig. 3 at A. When this mirror d has moved with the shaft 9 through a hundred and eighty degrees, the surface A<1> will reflect a spot of light on to the, scale which is represented at A'. By moving the scale box 7 along the quadrant 8 the spots A, A<1> will be formed for any points of the arcs 1, 3, Fig. 1. Similarly spots B, B<1> are formed by the surfaces B, B<1> of the mirror f for the arcs 2, 4, Fig. 1. The deviation is thus measured for any point of the whole revolution of the shaft. A mirror fixed to one of the flanges is arranged to give a zero spot on the scale. Specification 13448/06 is referred to.
