Title: Improvements in arrangements embodying positive column luminous tubes for televisionpurposes
IPC: H05B41/392
Filed: 1932-07-12
Abstract: 389,709. Television receivers. FERNSEH AKT.-GES., Goerzallee, Zehlendorf, Berlin. July 12, 1932, No. 19702. Convention date, July 30, 1931. [Classes 40 (iii) and 40 (v).] In a television receiver in which the output valve 1 of the low-frequency amplifier is associated with a positive column luminous tube 2 having a heated cathode 2<1>, in order to obviate any detrimental capacity to earth from the cathode 2<1> being furnished by the heating transformer or accumulators with consequent loss in signal strength at the higher frequencies, the cathode 2<1> is effectually connected directly to earth for alternating currents. In the arrangement shown in Fig. 2, the output valve 1 and tube 2 are connected in parallel with each other and in series with a non-reactive resistance 4, earth connections being made as indicated, while frequency distortion may be corrected by varying the mutual inductance between coils 5, 5<1> arranged in the parallel circuits. Since, in general, however, different working 'voltages are required for the valve 1 and tube 2, a compensating resistance 6 and condenser 7 may be included in the valve circuit, or the connections may be effected as shown in Fig. 3. In this arrangement the batteries apply the requisite voltages direct to the valve 1 and tube 2, while for alternating currents a direct connection between the cathode 21 and earth is provided by condenser 9 and the low resistance of the batteries 8. Specification 386,492 is referred to.

Title: Improvements in or relating to pneumatic sealing devices for container filling apparatus
Inventor: JONES WILLIAM CHARLES
IPC: B65B1/28
Filed: 1955-07-07
Abstract: 794,442. Filling containers with powder &c. BAKELITE, Ltd. July 5, 1956 [July 7, 1955], No. 19710/55. Class 94(1). Apparatus for use in filling containers with finely divided material comprises a filling hopper 13, a conduit 12 to connect the discharge end of the filling hopper to the container 11 and an inflatable endless tube 16 positioned so as to abut against the wall of the conduit and the rim 17 of the container to form a seal. A flexible canvas shield 14 is attached to the end of the discharge pipe 12 by means of a clamp 15 and is also secured to the endless tube 16 which is adjacent to the rim 17 of the drum 11. The tube 16 is also secured to a metal constraining sleeve 18 having handles 19. The sleeve 18 may be attached to a pivoted arm so that it can be raised thereby. An air supply line 20 is connected to the tube I6 and the three-way valve 21 enables the tube to be inflated or deflated at will. When tube 16 is inflated, it expands inwards since it is constrained by the metal sleeve 18 and in doing so traps the shield 14 against the rim 17 of the drum 11. The manner of trapping the shield prevents the accumulation of dust between the cover and the seal. Fig. 3 shows a modification in which the inflatable tube 27 acts between the rim 17 of the container and an annular backing plate 28 connected by a cover 29 to the discharge pipe 30. The container 11, is raised into sealing relationship with the tube 27 by inflating an annular tube 23 on which the container rests. The tubes are inflated and deflated simultaneously by air from a cylinder 31 with a piston 33 acted on by compressed air supplied through a three-way valve 32.

Abstract: 499,286. Pneumatic tyres ; cutting webs. FISK RUBBER CORPORATION. July 4, 1938, No. 19720. [Class 144 (i)] [Also in Group VIII] A machine for producing a composite tyre tread comprises means for forming transverse cuts in a length of tread stock, means for opening the cuts, and means for inserting thin pieces of a different rubber material edgewise into. the cuts. Fig. 13 shows the sequence of operations a, b, c, d, wherein the strip of tread rubber 10 is intermittently fed over a roller 11 to open the transverse cuts formed by a knife 12, and the leading end of a strip 14 of filler material is adhesively assembled in the cut by retractable gripper-jaws 15, 16 as shown at a, b. The jaws are then retracted (c), and the end of the filler-strip severed by a knife 18, whereupon both knives are withdrawn and the jaws re-engage the strip 14 (d). The knives 12, 18 are fitted with electrical heaters. As shown in Fig. 4, the spliced tread strip 10 is fed over rollers 29 on a table 27 and through a casing 30, which may be electrically heated, to the roller 11 over which the knife 12 is mounted. A spring- pressed roller 113 may be fitted to increase the curvature and tension of the strip in the cutting zone. After insertion of the fillerpieces, the strip is guided between a pair of endless bands 120, 123, and delivered on to a conveyer 136. The knife 12 is mounted in a block 91 fitted with an electrical heater 93 and carried by rods 94 from a yoke 97 which is reciprocated by a cam-operated link. The feed-rolls 29 for the tread strip are also actuated by the same link, and a spiked chain 33 may be fitted under the rollers as a further guide for the tread strip. The filler-strip 14 is fed from a roll 197 over roller 199, platform 200, rollers 202, 204, 206, 238, to a platform carried by the lower member of a pair of frames 240, 241 which are provided at their forward edges with gripper-jaws 15, 16. The frames 240, 241 are rocked to grip or release the filler-strip 14, and reciprocated to insert the latter into the tread cuts, by linkage-gear actuated by cams on the shaft 254. The severing-knife 18 and co-operating platen 19 are carried by rocking arms 277, 278 actuated from a cam-operated shaft 283. As previously stated, the tread strip 10 is preferably heated before reaching the knife 12 ; and, the advance of the latter in the cutting operation is slow enough to ensure a temporary destruction of the elasticity of the rubber at the cut.

Title: Process and apparatus for bending glass sheets
IPC: C03B23/031
Filed: 1962-05-28
Abstract: In a method for bending heat-softened glass sheets by sandwiching between complementary concave and convex glass shaping members movable towards and away from each other and between which the glass sheet is suspended, at least one of the shaping members moves upwardly at the same time as it moves inwardly towards the other shaping member.  Carriages 12 are moved by driving rolls 10 of a conveyer 11 through a tunnel-like furnace 13, Fig. 1, and carry glass sheets G through the furnace 13 to a glass shaping station 14 and thence to a quenching station (not shown) where they are subjected <PICT:0960514/C1/1> <PICT:0960514/C1/2> <PICT:0960514/C1/3> <PICT:0960514/C1/4> <PICT:0960514/C1/5> <PICT:0960514/C1/6> to jets of cool air in the usual manner. The carriages 12 are composed of cast iron alloy and comprise an upper beam 15 that rides on the rolls 10 and a lower beam 16 interconnected by a pair of connecting rods 17, Fig. 2.  Each glass sheet G is gripped at two spaced regions along its upper edge by a pair of steel alloy glass gripping tongs 18 suspended from each beam 16. When each heat softened glass sheet G reaches the shaping station 14 it is suspended between shaping members 20, 24 composed of heat resistant material such as stainless steel and having their shaping surfaces 21, 25 covered with fibre glass or asbestos.  The shaping members 20, 24 are mounted on pistons 23, 28 with a slight upward tilt which are movable in cylinders 30, 31 rigidly secured at 14.  Notched out portions 29 are provided to allow clearance for the glass gripping ends 19 of the tongs 18.  In place of the tongs 18, wires or refractory blocks may be used to support the glass sheet G.  In another embodiment, Fig. 4, the shaping members 20, 24 are tilted relative to the pistons 23, 28 such that the uppermost portions of the shaping surfaces 21, 25 are substantially tangent to vertical planes.  In further embodiments, as shown for example in Figs. 5, 7, 9, one of the shaping members 20, 24 is first moved into contact with the glass sheet G so as to position the sheet in a predetermined manner and the other shaping member is then moved into contact with the other surface of the glass sheet while it is thus supported.  Methods for controlling the relative timing of the movement of the members 20, 24 are indicated.  The invention may be used either for producing simple bends in glass sheets about a horizontal axis or compound bends about more than one axis including one having a horizontal component. Specifications 960,515 and 960,516 are referred to.

[Class 38 (iii).] Travelling to predetermined limits.-The setting of the pass indicator of a rolling mill is used to operate the pass adjusting motor through relays for the length of time required to operate the screws to adjust the pass to the particular setting. A control disc 1 is provided with a number of cam pins 3a, 3b, &c. which are set at different radii from a zero circle N to represent pass clearance, e.g. 210, 160, &c. millimeters. The disc is rotated one step after each pass by press-button 9, magnet 8, and pawl 6 to bring e.g. a pin 3a to lift the lever 11 thereby actuating a rack 14 to rotate a shaft 15 carrying the pointer 171 to show the pass setting on a scale. Rotation of the shaft 15, Fig. 2, separates relay contact arm 22 from 24 whereby the motor 32, Fig. 3, is actuated to turn the pass adjusting spindles 35, 36. The motor also rotates through gears 30, 31 the hollow shaft 20, Fig. 2, which after travelling a certain distance brings the contacts 22, 24 together again, and stops the motor 32, thus limiting the amount of pass adjustment to the setting indicated. Contacts 23, 25 remain closed until the pass is to be reduced when they open and act similarly to contacts 22, 24, but driving the motor 32 in the opposite direction for a certain time. The contacts 24, 25 abut against stop pins 27, 29 and engage tension springs 26<1>, 28<1> which allow this delayed action contact-closing until the required pass has been set.
