Title: Plug-in connection for electric switches
IPC: H01R13/707
Filed: 1931-06-18
Abstract: 374,637. Plug and socket couplings. PRENTICE, H. B., Primley Park Road, Alwoodley, Leeds. June 18, 1931, No. 17649. [Class 38 (i).] A switch of the kind wherein the live contact members are carried by a bar 1 rotated by a spring-controlled toggle and operating lever, is combined with a plug- and-socket coupling so arranged that the plug cannot be removed when the toggle is in the " on " position, by the action of means which are spring-retained out of action when the switch is " off, " the spring being overcome by spring- loading of the toggle when the means are put in action by the movement of the switch to " on." In the example, the means comprise a hook-ended lever 15, kept in the position shown by a spring 22, until the rotation of the bar 1 causes a pin 20 to engage in the slot 21 and cause the hook 17 to pass through the hole 13 in the earthing pin socket 11. As shown, the switch cannot be put " on " until the plug is in position, a plunger 23 being then displaced inward and the hook engaging an aperture in the earthing plug. In a modification, the plunger 23 is omitted, the switch can then be moved to " on " in the absence of the plug but the hook 17 would then prevent insertion of the plug.
Patent GB-827298-A (GB)
Title: Alumina-base catalysts and method of preparing same
IPC: B01J23/84
Filed: 1956-06-08
Abstract: A fluorine-free alumina-base catalyst is prepared by agitating an aqueous slurry of alumina and at least one oxide, hydroxide, carbonate or sulphide of cobalt, nickel, iron, molybdenum, tungsten or vanadium, separating solids from the aqueous medium, drying, and calcining.  The agitation may take place at room temperature or at 125-212 DEG  F.  When using sulphides, ammonia is advantageously added to the aqueous medium.  The alumina may be in particulate form, e.g. spray-dried microspheres, or in the form of dried or undried gelatinous hydrogel, and may contain minor amounts of silica, titania, zirconia, or thoria.  A small amount of alcohol may be added to the aqueous medium.  The component added to the alumina base may comprise 0.1-30% by weight of the total catalyst.  Before calcination the catalyst may be mixed with a die lubricant and tableted or extruded; alternatively it may be used in finely divided form. Suitable calcination temperatures are 800-1200 DEG  F.  The catalysts are useful for petroleum hydrocarbon reactions, e.g. hydrogenation, dehydrogenation, hydrodesulphurization, hydrocracking, hydrorefining and hydroforming, and for polymerization, olefine hydration, etherification, and oxidation reactions.  Examples describe the preparation of catalysts containing alumina associated with molybdenum, cobalt and molybdenum, nickel and molybdenum, iron and molybdenum, nickel and tungsten, and nickel and vanadium.  The insoluble compounds employed are cobalt carbonate, cobalt oxide hydrate, molybdenum trioxide, nickel carbonate, ferric hydroxide, tungstic acid, and vanadium pentoxide.  In Example I cobalt carbonate is incorporated with alumina according to the invention and the product is then impregnated with ammonium paramolybdate solution.  In Examples V and VI cobalt carbonate is incorporated with molybdena-alumina microspheres.  The Specification describes the use of a cobalt-molybdenum-alumina catalyst in the desulphurization of (i) a 348-667 DEG  F. sour heating oil from a West Texas crude, at 680 DEG  F. and 500 lb. per square inch gauge pressure, 10 WHSV, and recycling 3500 CF/B of 95 + vol. per cent hydrogen to the reactor after removing hydrogen sulphide; and (ii) a 416-611 DEG  F. catalytic cycle oil at 760 DEG  F.; 450 p.s.i.g.; 7.8 WHSV; and 700 SCF/Bbl H2 recycle.

Patent GB-1365838-A (GB)
Title: Data handling system
IPC: G06F9/46
Filed: 1972-04-21
Abstract: 1365838 Data handling INTERNATIONAL BUSINESS MACHINES CORP 21 April 1972 18552/72 Heading G4A [Also in Division H4] A data handling system includes a number of data handling devices each arranged to communicate with a common controller on an interrupt basis by issuing requests for access on a common interface, each data handling device having an assigned interrupt number and being operative when issuing a request for access to present its interrupt number to the interface, to compare its number with the number appearing on the interface, and to proceed with or abandon its request in response to the result of the comparison. As described several I/O devices are connected to a common serial bus, via an attachment module which may be as described in Specification 1,356,270. Each attachment module includes a control element 12 arranged to selectively control gates 11 in order to regulate the flow of data to and from registers. The module is arranged to compare data on the bus 2 with data in one of its registers to determine whether it should respond to instructions from the central controller. As described register 13 stores the module address which may also serve as the module interrupt number. Alternatively the interrupt number may be stored in a separate register 8. All modules monitor bit position 1 in each data group transmitted by the controller over the bus. When a 0 appears in this position indicating that the controller is available for interruption all modules requiring to communicate with the controller drive out the contents of their interrupt number register serially on to the bus. The modules simultaneously compare the signal on the bus from other requesting modules and drop out of the sequence on detecting a 1 bit on the bus when the corresponding bit of their interrupt number is 0. At the end of the sequence only a single module remains operative. An adapter in the controller reads data from the bus and thus contains the interrupt number of the remaining module which is subsequently selected by the controller. In a modification each module may have more than one interrupt number register in order to enable it to present high or low priority interrupt requests. The various interrupt registers in a single module may share a common register storing a common part of all the numbers. In a further embodiment the availability of the controller for interruption is signalled during a synchronizing bit period transmitted before each data group. The controller may then initiate the selection process by issuing an instruction code which occupies a part of the data group, the remainder being reserved for a comparison of interrupt numbers. The Specification describes a transistor circuit arrangement for sensing the current in the data bus, Fig. 5 (not shown).

Abstract: 816,827. Reciprocating pumps. SCHIRRMACHER, E. June 27, 1955, No. 18556/56. Class 102(1). [Also in Groups XXVI] A reciprocating pump has a slide valve 26 of annular form displaceable on the piston 21 to control the flow of liquid through ducts in the piston. As the piston, which is driven by the connecting rod 24, moves to right, the pressure in the cylinder space G moves the valve to the left so that the annular groove 34 is connected to the exhaust port 32. The liquid in the cylinder space G then flows through the apertures 36 and the hollow piston rod 22 into the delivery chamber F. On the suction side, the annular groove 33 is in communication with the inlet port 29 and the liquid is drawn in from the chamber E into the cylinder space H. For the duration of the stroke, the check valve R is open and, when the piston reverses its direction and moves towards the left the check valve is closed and the liquid trapped in the cylinder space H is compressed until its pressure exceeds that of the liquid still in the space G so that the valve 26 is moved to the right. The annular groove 33 is then connected to the exhaust port 32 and the annular groove 34 to the inlet port 30 thus reversing the pressure and suction sides of the piston.
