Title: Improvements in or relating to cable telegraphy and the like and circuits therefor
IPC: H04L25/24
Filed: 1926-08-19
Abstract: 282,130. Smith, W. S., McLachlan, N. W., and Jacob, W. G. R. Aug. 19, 1926. Restoring or modifying imperfect signals.- Relates to resistance-capacity-coupled amplifiers, particularly for use in cable telegraphy, and consists in the provision of a shunted condenser 32, Fig. 1, additional to the usual coupling condenser 33, together with a conductive impedance 41 in series with a compensating battery 42 adapted to equalize the mean potential on the two sides of the condenser 33. This arrangement stabilizes the mean grid potential by relieving the coupling condenser of the potential difference which ordinarily obtains between its plates. Wave-shaping and phase-shifting impedances may be employed, and the output of the valve 35 may be used for reception or for retransmission. In the form shown in Fig. 2, several shunted condensers 32 are provided and shaping networks 43 are added, to compensate for the attenuation of high frequency components in the cable. In a further modification (Fig. 3, not shown) the condensers 32, 33 have series resistances, the condenser 33 and its resistance are shunted by a further resistance, and the impedance 41 comprises resistance and inductance. The current may be limited by a low frequency impedance in the input coupling; thus in a duplex bridge the receiving diagonal may comprise a shunted condenser in series with the primary of a transformer, and in a simplex system the cable may be connected to the valve grid or to the primary of a transformer through a condenser, a shunt resistance being also provided. The valves may be arranged on the push-pull system, or in cascade. The resistances mav be variable and the inductances can in that case be adjusted by varying the polarizing current flowing in them.

Patent GB-189494-A (GB)
Title: Improvements in and relating to sheet glass drawing and delivering mechanisms
IPC: C03B33/10
Filed: 1921-08-03
Abstract: 189,494. Marks, E. C. R., (Libbey-Owens Sheet Glass Co.). Aug. 3, 1921. Drawing.- An apparatus for drawing glass in flat sheets comprises means for scoring or severing the sheet as it is drawn upwards, and a swinging carrier which is adapted to clamp the scored upper section of the sheet and deposit it upon an horizontal carrier which is movable to carry the sheet out of the path of the clamp. The tank 1 has a forehearth or drawing-tank 2, the temperature of the metal at the drawing point being regulated by adjustable water-coolers 6 and top tiles 4 which are carried by water-cooled supports 5. The sheet is drawn upwards by endless chains 14, connected bv grip bars 15, which grip the thickened edges of the sheet between them leaving the body of the sheet free from contact. Spring-pressed rolls 20 bear against the middle part of the chain and keep it in contact with the sheet. The sheet 30 leaves the drawing-mechanism through a slot between inclined roof plates 28, the slot being closed by strips 31 of asbestos to 'prevent broken glass from falling between the chains. Above the slot the sheet is scored bv a cutter 36 which acts against a backing-roll 32. The cutter 36 is spring-pressed against the sheet and is attached to one link of an endless chain 34, Fig. 3, that runs through a guide way 33 parallel with the face of the sheet. The chain is driven intermittently so that the cutter scores the face of the sheet at suitable intervals. The guide way 33 is inclined to the horizontal so that the cutter rises as it traverses the sheet and keeps the scored line at right-angles to the edges. Above the cutting-device, the sheet passes between a a frame 60 and a clamping-plate 61 both of which swing about a shaft 56. After the sheet has been scored, the plate 61 swings down into the horizontal position, thus successively clamping the sheet against the frame 60, breaking it along the scored line, and then carrying it down into the horizontal position where it is deposited on rollers 70 that convey it to the lehr.

Title: Method and apparatus for cracking oil
IPC: C10G9/14
Filed: 1930-07-08
Abstract: In a process for cracking oils of the kind described in Specification 317,507, [Class 32, Distilling &c.], in which oils are vaporized in a tubular system with removal of fractions not vaporisable without decomposition and the vapours are cracked in a second tubular system, the vapours are freed from fog without cracking prior to entering the cracking zone by passing them through a superheating zone comprising tubes of relatively great cross section as compared with those used in the vaporizing and cracking zones.  Oil from a storage tank 1 is pumped through a line 2 and jet 6 to a conversion arrester 4 where it meets the stream of vapours leaving the converter 5, the oil being tapped while the temperature of the cracked vapours is reduced from about 1000 DEG  F. to 600 DEG  F.  The mixed oil and vapours are passed to a fractionating tower 8 the temperature of which is controlled by steam <PICT:0353230/III/1> circulated through a coil 11, water tank 12, separator 16 and heating coil 20.  The vapours pass off through a line 10 and condenser 22 to a separator 23 from which the end product passes to a tank 26 and the gases are withdrawn through a pipe 24 to compressors for partial conversion to motor fuel.  The condensate from the tower 8 is in part recirculated to the tank 1 and in part passed to a tubular vaporizing coil 29 arranged in a flue 30 in the wall of the converter 5 and heated to 600--750 DEG F. by the waste gases therefrom.  The products are led to an evaporator 32 for removal of unvaporized fractions and thence to drying tubes 38 of larger cross section where they are given 30--50 DEG  F. super-heat and are thus freed from fog without cracking.  The direct vapours pass through a pipe 39 to a header 40 from which they are distributed to a number of valve-controlled parallel cracking tubes 43 heated to about 1000 DEG  F. and preferably provided with cores containing ferrous oxide.  The cracked vapours are collected p in a header 50 and passed through tubes 49 of large cross section where the cracking conditions are equalized and the necessary time for completion of cracking is obtained.  The conversion furnace is divided by a wall 44 into combustion and tube chambers 45, 21, the cracking tubes 43 extending across the wall 44.

Title: Improvements in or relating to pneumatically operated reciprocating tools
Inventor: STANWORTH STEPHEN
IPC: B21D22/00
Filed: 1965-05-18
Abstract: 1,118,691. Power hammers. STANDEL Ltd. 18 May, 1966 [18 May, 1965], No. 20899/65. Heading B3H. [Also in Divisions F1 and F2] A pneumatically operated press tool such as a punch, comprises a piston 154 working in a power cylinder 18 and subjected to differential air pressure on its opposite ends for actuating the tool on its working stroke, and means 20, 200, external to the cylinder are provided for retracting the tool. Pressure air from a supply pipe or a separate compressor, is admitted to cylinder 18 through pipe 30, master control valve 32 and filter 34, and acts continuously on both ends of the piston 154 which carries a piston rod 22 passing through the retraction cylinder 20 and connected to a chuck carrying a punch or die. Within cylinder 20 a piston 200 is secured to the piston rod 22, Fig. 2 (not shown) and pressure air is admitted beneath this piston through duct 202 and valve 204 for raising both pistons 200, 154 and holding them temporarily in their raised position. In this position a guard 92, covering a die or tool on base portion 12, is raised by linkage 88 connected to a hydraulically operated piston rod 60, to enable replacement of the workpiece. The press works continuously and therefore after a delay, as determined by an adjustable valve 130 on a timer device 100, 131, the hydraulic piston rod 60 is released whereby the guard 92 falls by gravity assisted by spring 93. Thereafter valve 204 opens a large exhaust port (234), Fig. 6 (not shown), to exhaust the air below piston 200 thereby causing the tool to move downwardly on its working stroke. Valve 204 may be adjusted by member (224), Fig. 6 (not shown) for controlling the working speed of the tool. The working stroke is cushioned by piston 154 entering a recess (158) in cylinder 18, Fig. 2 (not shown). The press column 14 forms a reservoir in which oil is retained under air pressure; an air filter 132 is provided. Oil for lubricating purposes is supplied to cylinder 18 through pipe 184 from a diaphragm pump 162, Fig. 3, actuated by engagement with the bottom of the hydraulically operated piston rod 60. The pump draws oil from the oil reservoir through pipe 168 and inlet valve 172 and delivers it through outlet valve 178. A porous bronze oil filter 48 in cylinder 18 controls the amount of oil carried by the air. A swarf blower may be connected to pipe 102. The piston rod 22 may alternatively be raised mechanically instead of by piston 200.

Abstract: 359,019. Spray carburetters. MANNERS, W. H., 26, Dingaan Street, Krugersdorp, Transvaal, BARKER, N., 7, Trust Buildings, Fox Street, and M. & S. CARBURETTOR MANUFACTURING & FINANCE CORPORATION, Ltd., 86, Main Street, both in Johannesburg, both in South Africa. July 14, 1930, No. 21266. [Class 7 (iii).] The fuel supply is controlled by a tubular member 6 having a narrow longitudinal slit 8 and a rotatable valve comprising two parts 9, 10 housed within it, the part 9 having a helical edge 11 which coacts with the slit so that equal angular movements of the valve open or close equal portions of the length of the slit. Fuel from a float chamber passes through a passage 19 into an orifice 20 in a boss 5, and through a plug 7 to the lower end of the member 6. A fine slit 15 extends upwards from the edge of the helical part 11 to promote the flow of petrol by capillary action. The elements 9, 10 are rotated by a lever 26 provided with set-screws 28 which determine the setting of the lever 26 relative to the helical edge 11. The lever 26 is connected by a link 31 with other levers 45, 62; thus the air-admission and mixture-outlet valves 42, 59 are operated simultaneously. Screws 50 permit a small independent adjustment of the air-admission valve 42. A fixed stop 68 and an adjustable stop 69 limit the movement of the lever 62. The body of the carburetter between the valves 42, 59 is constructed so that the passage 72 tapers from the centre towards the valves. An air-strangler valve 52 is used at starting. In a modified construction, Fig. 9, the tubular member 73 has an arcuate slit 74 with which co-operates an edge 78 on a valve 75, rotation of which varies the length of the slit. The invention is applicable to a downdraught carburetter.
