Title: Improvements in changegear mechanism more especially applicable to automobile vehicles
IPC: F16H61/02
Filed: 1927-07-09
Abstract: 300,667. Lanchester, F. W., and Lanchester's Laboratories, Ltd. July 9, 1927. Variable-speed gearing comprises two or more units of epicyclic gear trains controlled solely by axial movements of frictional elements in combination with means for maintaining a frictional element in freed position so as to yield free engine ' when desired. In the arrangement shown in Fig. 1, there are two two-speed units A, B, and a reversing-gear C. In unit A, the internal ring d is secured to the driving-shaft d', the planet carrier c is secured to the driven shaft f, and the sun gear g is adapted to be clutched solid, or held fast, or, by additional means, freed. The sun gear g is long and is adapted to slide with its sleeve g<1> and a double cone clutch n<1>, n<2>. A spring h normally holds cone n' engaged with a cone k on the ring d for solid driving. To bring in the low speed, the controlling element m, which is a non-rotating cone, is slid to the left so as first to engage cone n<2> and then to slide the double cone to the left disengaging cone n<1> and holding the engaged parts against rotation. This control movement is effected from a pedal through a rock-shaft S, Fig. 2, and arms s<1>. Separate means to disconnect the drive comprises a second rock-shaft t, which has arms t<1> acting through a thrust bearing 45 on the end of sleeve g<1>. Selectively operating pneumatic plungers are described by which either of the shafts s, t can be operated by depressing the pedal. The shaft f is the driving-shaft of the second unit B, of which the sun gear o drives and the planet carrier 48 is driven. The double clutch 20 is on the ring p and speed is changed by sliding a non-rotary friction member r. r. This effects that ring p is clutched solid or held fast alternatively. No free position is required here. Four speeds have thus been given to shaft 32. The reversing unit C comprises a planet carrier 34, with rings of clutch teeth 36, 37. When this is slid to the right, the teeth 37 engage over the driving sun pinion 33 locking the train 33, 46, 47 to turn solid. When the carrier 34 is slid to the left, the teeth 36 engage fixed teeth 35 so that the pinions 46 turn on fixed pivots and drive the ultimately-driven ring 47 backwards.

Title: Improvements relating to electrical primary cells
IPC: H01M6/08
Filed: 1942-12-28
Abstract: 562,280. Batteries. SIEMENS BROS. & CO., Ltd., and LAMBERT, G. M. Dec. 28, 1942, No. 18405. [Class 53] [Also in Group V] In a primary cell having a solid depolarizing mass, the most active depolarizing agent (e.g. manganese dioxide) is in greater concentration at the surface nearest the positive electrode (e.g. zinc) than at the surface nearest the negative electrode (e.g. carbon). The depolarizing mass may be formed in separate cylindrical layers 4, 5, 6 with a different content of manganese dioxide. The three cylindrical layers may be formed by a continuous operation in a machine having a horizontal service table 7 and a carrier table 15, both rotated step by step. The table 7 has three circular rows of holes 8, 9, 10, the diameters of which correspond to the outer diameters of the cylinders 6, 5, 4 respectively, and the table 15 has one row of holes, the arrangement being such that each hole in disc 15 comes successively under a hole in each of the rows 8, 9, 10 in table 7. In position A of table 7, the holes in table 7 are filled from hoppers with depolarizer of different composition, Fig. 3 (not shown) ; in position 11, the depolarizer in one of the largest holes 8 is forced into a hole 16 in table 15 by a pressure spindle 25, Fig. 4, the centre of the mass being forced through a die 27 by a coring spindle 24, so as to leave a cylindrical mass of depolarized in the hole 16. When this hole 16 in plate 15 moves into the positions 12 and 13, the process is repeated, middle and inner cylinders of degolarizer being formed within the outer one, Figs. 5, 6 (not shown). When the hole 16 reaches positions 35, 36, 37 a carbon electrode is forced into the centre of the inner cylinder, Fig. 7 (not shown), the three cylinders are compressed into one mass and the carbon electrode forced home, Fig. 8 (not shown), and the finished dolly is ejected, Fig. 9 (not shown). The invention may also be applied to the layer type of cell. The Provisional Specification states that different depolarizers may be used in the several layers.

IPC: A01K11/00
Filed: 1928-06-25
Abstract: 319,081. Hall, I. June 25, 1928. Surface and outline gauges.-The gauge shown in Figs. 5 and 6 is provided for checking stud seals attached to the ears of animals, or to articles such as clothing, and comprises an identification disc 1, Fig. 1, having a distinguishing surface contour, for example radial ribs 7 in a star pattern and a peripheral rim 6 with a notch 8. The gauge consists of a tube 9 closed at one end and containing at the other end a spring-pressed plunger 10 adapted to be depressed by the identification disc when the parts are in correct register, to a predetermined extent indicated by a pointer 17 reading over a scale within the tube and exposed through a slot 16. The pointer 17 forms part of a lever 13 pivoted on a support 14 within the tube and bearing against the plunger under the action of a spring 18 fixed to the support 14. The mouth of the tube has an upturned shoulder 22 with a projection to register with the peripheral notch of the identification disc, and the plunger is contoured to correspond with the raised pattern on the disc, so that full depression of the plunger is obtained when the parts register, in which case the rim of the disc rests on the shoulder 22. Rotation of the plunger is prevented by means of a longitudinal groove therein engaged by a grub screw 20. In a simplified construction, the plunger is extended in length beyond the slot in the tube and bears an index line for register with arrow marks on the tube, a spiral spring is located between the end of the plunger and the closed end of the tube, and rotation is prevented by means of a groove and a screw. The gauge shown in Fig. 10 is provided for an additional check in conjunction with recesses in the opposite disc member of the identification device, which may also have a peripheral rim with one or more notches. The gauge consists of a number of spring-supported stems 27 within a tubular casing 25, normally projecting at one end, and coming flush in apertures 26 at the other end when depressed by a disc having recesses of the correct disposition and depth; the end of the casing may be shaped to receive a peripheral rim with one or more notches.

Title: Improvements in valve gears for steam engines
IPC: F01L31/16
Filed: 1931-06-25
Abstract: 380,528. Engine valves and valvegear. BOLLA, G., 3, Via Valle, Trecate, Italy. June 25, 1931, No. 18455. Convention date, June 25, 1930. [Classes 122 (i) and 122 (ii).] Steam engines, particularly locomotives, are provided with cam-operated, lift, admission valves, and fluidactuated exhaust valves. The cams rotate and are continuously reciprocated axially relative to rollers engaging them. The control is effected by timing the reciprocations relative to the crankshaft. The cams comprise cylindrical bodies 44, 45 each of which is fitted with a chamfered rib 1 extending through 180‹. The cams are operated by a centrally-placed shaft 21 driven from one of the wheel axes by bevel gearing and a Cardan connection. Bevelled rollers mounted on levers 41 operate tappets 5 which through rods 14, 15, levers 17 and bell cranks 16 act on admission valves. The shaft 21 is turned through 180‹ on moving sleeve 40 longitudinally. The cams 45, 44 are connected to cams 7, 7<1> which are moved longitudinally to determine the cut-off by rollers 9 carried by an arm 10 which can be angularly adjusted by a toothed sector 12 and pinion 11 outside the cam-gear casing 18. The exhaust valves 29 are connected to differential pistons 31, 32. The piston 32 is constantly subject to pressure ; the annular area above piston 31 is connected through a pipe 30 to the opposite cylinder and the steam pressure in which opens the valve. When the end of the passage 35 is uncovered upon the descent of the valve the pressure above the piston 31 falls, and the pressure on piston 32 closes the valve. A relief valve 43, Fig. 7, is arranged below the cylinder, and is normally closed by the pressure in pipe 34.

Title: Improvements in and relating to magnetic recording and/or reproducing apparatus and magnetic record carrier therefor
Inventor: KUHSE PAUL
IPC: G11B15/34
Filed: 1958-06-10
Abstract: 833,413. Magnetic sound recording and reproducing apparatus. GRUNDIG, M. June 10, 1958, No. 18530/58. Class 40 (2). A drum and sheet record type magnetic recorder has outwardly sprung driving members on the drum engaging in corresponding holes in the record. The corresponding machine is the subject of Specification 833,408. The drum 2 exactly accommodates the length of the record 1 without overlap. The magnetic head is guided by grooves (not shown) in the central recording area 7 of the record, which are slightly inclined to the axis of the record so as to form a continuous helix when the record is mounted on the drum. The driving members 10 have each two outwardly-facing working edges 13, one of which terminates in a raised pawl-form step 14. The record contains in a margin (or in both margins of a wide record) two series of perforations 8, 9 relatively near each end of the record, of which the wider series 8 will accommodate the whole width of the driving member 10 while the narrower series will only accept the pawl sections 14. The spacings between the perforations are such that if a perforation 8 engages the drum as in Fig. 1 and the drum rotated, the next driving member (10 in Fig. 1) will come between the perforations and will be compressed flush with the drum surface by the record, while the pawl 14 of the remaining driving member will engage with one of the perforations 9. On reversal of the drum, as required in the automatic operation of the machine, the now leading edge of pawl 14 takes over the drive of the record and prevents any folds forming in the record.
