Title: Improvements in vacuum electric tube devices
IPC: H01J19/40
Filed: 1927-12-13
Abstract: 307,856. Robinson, E. Y., and Associated Electrical Industries, Ltd. Dec. 13, 1927. Vacuum tubes.-In thermionic valves having indirectly-heated cathodes, screens are arranged to shield the electrode system either from the heater leads which proceed from one stem and are connected to the heater at the opposite ends of the electrode system, or from a resistance which is arranged in series with the heater to enable the valve to be fed from the mains. The first arrangement is shown in Figs. 1 and 2, in connection with a valve of the kind described in Specification 195,691, wherein the space current is confined to a small inter-electrode space, and a carbon heater is wound on a porcelain rod 2 which is secured by clips 3 as described in Specification 297,966, one of the heater leads 14 being passed outside the electrode system to the top of the cathode and enclosed in metal screening tubes 15. These are connected at 17 to a cylindrical screen 9 that surrounds a network anode and the other electrodes and is connected electrically at 11 to the cathode as described in Specification 307,857. The ends of the cathode tube are left non-emissive so as to act as screens, and washers 12 that centre the cathode at the top and optionally also at the bottom may also act as screens. The second arrangement (Fig. 4, not shown) is obtained by extending the screen 9, Figs. 1 and 2, to support the series resistance above the screening washer 12, the resistance being placed in the return lead 14. In a modification, the heater leads are sealed in a stem 28, Fig. 5, at the top of the valve, and a resistance 25 is placed in series with the heater. A screening disc 30, and optionally also a screening cylinder mounted on the wires 29, shield the resistance from the electrode system.

Title: Improvements in or relating to the looper drive for double chain stitch sewing machines
IPC: D05B57/02
Filed: 1957-10-31
Abstract: 869,637. Sewing machines. PFAFF A. G., G. M. Oct. 31, 1957 [Nov. 2, 1956], No. 33954/57. Class 112 The needle-evading movement provided by the looper driving mechanism of a double chain stitch sewing machine having needle and base feeding means is composed of a constant movement on which is superimposed a variable movement dependent upon the advancing movement of the needles. The invention is described as applied to a two needle, feed-off-the-arm machine. The feed dog 20 on its feed-bar 22 receives lifting movement from a link 52 connected to one end of a lever 50 pivoted at 51 to the arm 5, the other end of which is oscillated by a pitman from an eccentric 48 on the shaft 6. Feed advance movement is given to the feed-bar through a link 26, pivoted at 67 to the arm 27 of a bell-crank 28. The other arm 33 of the bell-crank is oscillated by a pitman 34 from an adjustable eccentric 35 mounted on the shaft 6. The loopers 53 are carried on a looper shaft 57 which is oscillated, to provide a loop entering motion, by a crank 58 driven from the shaft 6. A bellcrank 65 also pivoted at 67 to the arm 27 of the bell crank 28 has one arm 64 engaged with claws 61 on the shaft 57 to provide the needle avoiding reciprocation of the shaft, the motion of the bell crank due to the adjustable movement of its pivot 67 being combined with a constant oscillation of the bell crank derived from a pitman 70 and an eccentric 71 fixed to the shaft 6. The swinging movement of the needles in the sewing direction is derived from a lever 18 connected to an adjustable eccentric 12 by a pitman 17. To synchronise the needle swing with the feed dog movement the cam setting members 13, 36 are provided with grooves 14, 37 which may be aligned with each other by engaging, respectively, the detents 16, 38 on a bridge 15. The bridge is normally urged away from the members by a spring 44, but may be depressed into engagement by a push button 47.

Patent GB-627060-A (GB)
Title: A process and apparatus for the working up of whale meat
IPC: A23B4/03
Filed: 1946-11-15
Abstract: In a process for the treatment of whale meat for the direct manufacture of stable products poor in oil by heating the meat in a sub-divided condition in water at atmospheric pressure for less than 1 hour while it is being agitated and subjected to the action of steam introduced into the charge of sub-divided meat and water, pressing the so-treated meat and drying the resulting heated and pressed meat in hot air driers or other drying apparatus, wherein the meat enters into direct contact with heated apparatus elements, the meat prior to pressing is wished with water to remove or dilute the glue formed during the heating operation. The washing may be done by warm water during the passage of the meat between the heating apparatus and the press.  The meat may also be washed with warm or cold water before it is subjected to heating.  In an example, a cooker of the type employed in herring oil factories is filled with water and steam is introduced through supply pipes at the central parts.  Sub-divided whale meat is introduced in the usual manner and water is supplied through the inlet pipes, the largest amounts being introduced at the central and end parts.  The water supplied in the charging end parts washes out or dilutes the dissolved substances in the pores of the meat while the water introduced in the end parts washes out and removes the layers of glue.  The meat may be heated to near 100 DEG C. when the flow of water through the charge is sufficient.  From the cooker the meat is continuously conveyed through a strainer, a screw press and a disintegrator to a hot-air drier.  Norwegian Specification 60436 is referred to.

Patent GB-342078-A (GB)
Abstract: 342,078. Totalizators. WARD, T. E., 475, Oxford Street, London. Dec. 13, 1929, Nos. 38251/29 and 25840/30. [Class 106 (i).] In a totalizator of the electrically-released ball type, the counting-mechanism for each denomination is the same and comprises a shaft 10 carrying a sleeve 12 on which are secured a ball-actuated wheel 27, a detent wheel 22 engaged by a spring- controlled roll 25, a transfer wheel 33 and a bevel wheel 16 gearing with a drum 40 for driving an endless indicating-band. The released ball falls down a tube 30 and serves to connect a constantlydriven wheel with the wheel 27 to rotate the sleeve one step. At transfer a contact 34 on the wheel 33 completes circuit to the ball-releasing magnet of the next higher denomination. If other and duplicate indicators are to be controlled this is effected by a further wheel 48 fixed on the sleeve 12 and provided with ten circuit-closing contacts 52 for releasing balls to actuate similar counters. To reset the apparatus the shaft 10 is given one rotation to enable a pawl mounted on the boss 19 to pick up a no ch in the surrounding hub of the wheel 16. The shaft 10 may be common to all the denominations of the counter, so that all the bands may be returned to zero by the one operation. Fig. 13 shows a system wherein a ball-actuated mechanism is inserted in the tube 30 leading from a number of hoppers 80 .. 84 to a grand total counter and indicator 85. On the sleeve 12 of the mechanism are fixed five discs 55 .. 59 each provided with two diametrically opposed contacts constituting throughout the series ten equally spaced contacts. These complete circuits to five hoppers 91 .. 95 to release balls for actuating the counter 96 relating to the horse concerned.

[Class 100 (i)] Delivery apparatus.-Apparatus for preventing folded products from nesting one within another as they are delivered from rollers 1, 2 of a folding-machine to a conveyer-band 6 comprises a spring arm 8 mounted on one of the side guides 7 beneath which the open end of the product 4 is forced by a pneumaticallyoperated plunger 16 as it leaves the rollers 1, 2. The arm 8 carries a sheet-engaging roller 9. The plunger 16 is connected to a piston 15 the underside of which communicates with a suction device but is normally kept at atmospheric pressure by an opening 14, so that a spring 19 retains the plunger 16 in its raised position. Holes 18 keep the space above the piston at atmospheric pressure. A product 3 leaving the rollers 1, 2 engages a spring so as to close the opening 14. Suction then operates on the lower face of the piston 15 to cause the plunger 16 to move downwardly and push the product past the spring 8. Near its lowest position the piston 15 opens the suction conduit to the space above it at atmospheric pressure, thereby allowing the flap 13 to spring back to its normal open position and allowing the spring 19 to return the plunger to its raised position. The conveyer band 6 may be arranged to travel in the same direction as the sheets leaving the machine.

Divided out of 817,532 [Group VII]. Class 39(3) [Also in Group VII] Apparatus for heating shoe bottoms (see Group VII) includes heating boxes each comprising hinged parts 32, 34, Fig. 2, with supporting grids 40, 42 and heating elements 54, 56, the angular relation of the two parts being adjusted through arm 46 and cam 50 by means of knob 52. Louvres 70 pivoted at 68 at the bottom of the boxes are held in closed position, as shown in Fig. 2, by engagement of pins 74, 72 (not shown) with the ends of the louvres, but when bars 76, 78 carrying the pins 74, 72 are moved endwise, by movement of handle 148 (not shown) the louvres fall downwards to an open position and permit cooling air to enter, e.g. when the operator wishes to leave the machine. In one construction a set of four boxes is associated with each of two sole attaching presses, and the arrangement is such that operation of one press brings to a forward accessible position a box, associated with the other press, and in which the shoe is ready for attachment. A further apparatus described comprises a rotatable turret having eight stations each comprising a press means and a heating means. The heater boxes are arranged as in Fig. 10, on a casting 204 (not shown) rotatable on a stationary pillar 202, and are similar to those described above except that the shutters are normally closed by springs 210 acting on bars 76, 78, and opened by anti-clockwise movement of handle 242 which acts through pawl 240 and ratchet 236 to move disc 226 about pillar 202 so that rods 228 projecting from the disc and engaging in slots 224 in the rotatable ends 222 of arms 220 turn clockwise rockshafts 218 which through arms 216 and links 214 move arms 76, 78, thus opening simultaneously the shutters of all the boxes. A ratchet 230 (not shown) on disc 226 and a stationary pawl 234 (not shown) permit anti-clockwise movement of disc 226 relatively to casting 204 (not shown), but prevent relative clockwise movement, thus preventing spring 210 from closing the shutters until the turret makes its first movement. Current for heating the boxes 206 is supplied through a brush and slip ring contact, the rings being mounted on a block secured to casting 204 and the brushes mounted on a stationary casing surrounding the block and secured to pillar 202. Leads from the rings are connected to the boxes, and leads from the brushes pass through pillar 202. Specification 408,953 [Group VII], also is referred to.
