Title: A process for the preparation of sulphur trioxide
Inventor: MOLLER WIHELM
IPC: C01B17/76
Filed: 1961-02-20
Abstract: In a multi-stage process for the catalytic production of sulphur trioxide from sulphur dioxide and oxygen, any sulphur trioxide formed in a previous stage is at least partially absorbed and the gas remaining after SO3-absorption is reacted in a further catalyst stage at a temperature which is below the temperature which existed before absorption of SO3. Preferably the further catalyst stage is effected at a temperature 40 DEG -60 DEG  C. below the previous gas temperature.  Oxygen may be supplied in the form of air.  SO3 produced at any stage in the process is preferably completely absorbed.  In an example using a multistage Kieselguhr-V2O5 catalytic reactor initial conversion of SO2 to SO3 was 85-90% at 450 DEG -460 DEG C.  Absorption of SO3 with H2Sl4 was effected and the residual gas having cooled by 60 DEG -80 DEG C. was reheated to 390 DEG -410 DEG  C. before reintroduction to the reactor. In this way overall conversion of SO2 to SO3 was 99,6-99,8% by volume.

Title: Improvements in or relating to grabs, lifting-dogs and like lifting and lowering apparatus
IPC: B66C3/06
Filed: 1921-02-24
Abstract: 185,138. Hollick, W. J. Feb. 24, 1921. Addition to 134,968. Grab-buckets; grab-forks. The coupling, mechanism. for operating the grab described in the parent Specification, comprising a member carrying fixed pins which co-operates with a rotary cam-carrying member, is modified by providing retractable pins thereby enabling the coupling-members to be separated for direct dumping of the load without relative rotation of the coupling-members, while retaining the feature of relative rotation to produce the engagement of the coupling. To facilitate the operation of the catches the rotary cam-carrying member is mounted on the bucket frame instead of on the lower sheave block, while the pin-carrying member is transferred from the frame to the block. Fig. 1 shows one construction in which the pins or catches n engage the rotary cam-carrying member 0 in the manner described in the parent Specification when the lower sheave block q is lowered. The pins can be withdrawn against the action of springs by tension applied to the cords 12. Weights may be used in lieu of springs. In a modified construction the outer ends of the catches abut against the interior of a coned sleeve, which normally retains them in the acting position, but permits the load to retract them by forcing their bevelled inner ends apart when the sleeve is moved axially. Fig. 4 shows a further modification of this form in which the catches are slotted to receive sliding wedges 14 which allow the load to retract them when the cords 12 are pulled. The raising of the wedges rotates arms 15 into the path of the falling cam-member so that the wedges are operated to reset the catches during dumping of the load. As applied to a grab-fork, the cam-carrying member of the coupling is connected to the pivot of the fork and the sleeve carrying the catches is connected to a ciosshead to which the upper arms of the fork are connected by rods, the opening and closing of the fork being effected by the engagement and disengagement of the coupling.

Title: Improved process of dehydrating aleohol
IPC: B01D3/00
Filed: 1923-03-03
Abstract: Ethyl alcohol is dehydrated by admixing with a hydrocarbon oil, preferably of higher boiling point than the alcohol, heating the admixture with lime and distilling off the alcohol.  Suitable oils are kerosene, naphtha, naphtha bottoms, gas oil, &c.  In an example 95 per cent alcohol is mixed with about 25 per cent of above 43 DEG Baum<\>ae kerosene, and 10-15 per cent more lime than is required to combine with the water.  The mixture is refluxed for some hours and then distilled, the distillate being fractionated or condensed together, according to whether absolute alcohol is desired or not. If the vapours are condensed together, the mixture may be employed together with gasoline as a motor fuel. Kerosene may be recovered from the residue by passing in an inert gas, such as natural gas, under pressure, with or without heat. The lime may be regenerated by calcining.  Alcohol denatured with benzol, pyridine, wood alcohol &c. may be similarly dehydrated.

Title: Mechanically operated brake for railways
IPC: B61K7/06
Filed: 1929-02-26
Abstract: 329,057. Marchais, G. Feb. 26, 1929. Frictional apparatus on permanent way; electric. - Track brake apparatus comprises shoes which when moved against the sides of the wheels are moved apart by wheels and rocked round a pivot whereby the track rail is raised. The brake is operated by a. frame 25, Figs. 1 and 3, which when moved longitudinally causes inward movement, bv means of oblique links 22, of members 15 running on rollers 17, 18 and also of the brake shoes 7, S, which are connected by adjustable eccentric swivel joints 13 to the members 15 and the following brake members 9. The shoes are mounted on bearing surfaces a - - d on chairs 2 carrying the rail 1 and when the brake is in operative position and a vehicle wheel passes between the shoes the latter are spread apart and cause the members 15 to pivot on the axis of rollers 17 thus raising the chairs 2 and the rail 1. The chairs 2 rest on; a metal sleeper 4 and are guided bv vertical surfaces. The braking pressure on each side of the wheels is equalized by transverse movement of the shoes and operating mechanism. The frame is operated by a crank 40 and a rod 42. The rod 42 from each group of brakes is connected to a lever 57 having a groove engaged by a knob 55 on a. manually rotated drum 54 which sets the levers in turn in braking or non-braking position with one or other of the concave sides of the lever against a drum 56. A recess 56<1> behind the drum allows rotation of the levers. The drum 54 is rotated by a cable 53 from a drum 50 which is rotated by a drum 46 by means of a friction strip 48 connected to a projection on the drum 50 by a knob 49 and passing round a ratchet wheel 51, revolving freely in the braking direction but arrested in the opposite direction. To release the brake the rotation of the drum 46 is reversed, the strip 48 thus slackened and a knob 52 on the pulley 46 drives the pulley 50 to release the brake. If however a vehicle is passing while the release is produced the reaction in the brake mechanism tightens the grip of the friction strip and prevents release. The apparatus may be operated by an electric motor controlled by hand operated switch rings and rings operated by the motor to obtain a step by step operation. Two contacting relays for starting the electric motor, one for braking and one for release, are provided. The motor operates through a non- reversible reducing gear. The control switch may comprise a series of interconnected push buttons 76, having projections 78, 79 and an insulated contact part 80. Bars 82, 86 secured to levers 83, and having projections 81, 85 engaging the projections 78, 79, are urged towards the left by a spring 87. Each knob is locked by its projection 79 when pressed down and is released by pressing down another knob which moves the bars to the right by means of its projection 78.

Title: Improvements in or relating to Receivers for Amplitude Modulated Suppressed Carrier Signals
IPC: H04N9/66
Filed: 1967-02-10
Abstract: 1,182,354. Colour television; radio receivers. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 10 Feb., 1967 [12 Feb., 1966], No. 6371/67. Headings H3Q and H4F. The invention relates to a receiver for the P.A.L. colour television system in which a phase-switched oscillation from oscillator 3 is added to the chrominance sub-carrier signal before the quadrature modulation components are separated in the conventional manner in delay line system 8, 9, 10 and applied to amplitude detectors 11, 12, 13a, 13b. Due to amplitude fluctuations in the output of oscillator 3 arising from the use of colour synchronizing " burst " signals which recur at line intervals and other factors the detector outputs include fluctuating direct-voltage components. In accordance with the invention these components are cancelled by deriving direct voltages dependent upon the output of oscillator 3 with the aid of detectors 20, 21 and adding the voltages in opposition to the detector outputs. Fine adjustment to ensure complete cancellation is achieved by a resistor 25, which adjusts the amplitude of the reinserted oscillation, and by means included in the leads from detectors 20, 21.

Patent GB-565378-A (GB)
Title: Improvements in or relating to electric circuits incorporating resistance strain gauges
IPC: G01L1/22
Filed: 1943-04-22
Abstract: 565,378. Thermionic valve voltmeters. AUGHTIE, F. April 22, 1943, No. 6517. [Class 40 (v)] [Also in Group XXXVI] An amplifier having negative feed-back is used in conjunction with an electrical resistance strain gauge so that the effective amplification becomes inversely proportional to the gauge resistance. This results in an amplifier output which is substantially proportional to strain irrespective of stain gauge resistance, so that any one of a series of gauges of the same order of resistance can be used to give a direct indication of strain on the same scale. Fig. 1 shows a two-valve amplifier in which a strain gauge resistance R1 is connected in the gridcircuit of the first valve V1 and is fed from the cathode of the second valve V2 (which operates as a cathode follower) through a resistance R2. Resistances R3, R4 are included in the anode and cathode circuits of the valve V1. A meter M is connected between the cathode of the valve V2 and the junction of two resistances R5, R6 connected across the A.C. supply, or it may be connected directly in the cathode circuit. The instrument M gives the same reading for the same strain irrespective of the gauge resistance. A change of gauge resistance, however, alters the zero setting and this must be corrected by altering the bias of the valve V1 by means of a resistance R7. The resistance R4 may serve as a compensating gauge to correct for changes of temperature of the gauge R1. In the circuit shown in Fig. 2, the main and compensating gauges R8, R9 are connected in the grid circuits of two valves V3, V4 operating in push-pull. The anodes are connected, through an intermediate stage V5, V6, to the output stage V7, V8. As the extra stage causes a reversal of phase the feed-back connections are crossed, so that the valve V7 feeds through a resistance R11 to the resistance R9, and the valve V8 feeds through a resistance R10 to the resistance R8 and valve V3. This provides negative feed-back with respect to differential changes of voltage between the grids of the valves V3, V4. In order to ensure stability, a common cathode resistance R14 is connected to the cathodes of the valves V3, V4 so as to reduce the voltage gain of both valves for voltage changes which are in phase, whilst being without effect on the gain of voltages which are out of phase. A common cathode resistance R18 to the valves V5, V6 similarly controls the operation of the second stage. The screen grids of the valves V3, V4 are supplied from the cathodes of the valves V5, V6 to reduce the amplification of in-phase changes. If the screen-grid current of the valves V3, V4 is less than the cathode current of the valves V5, V6, a shunt resistance R19 is connected as shown. A slider resistance R15 provides for zero adjustment. Resistances R20 R21, R22, R23 are provided for inhibiting parasitic high-frequency .oscillations.
