Title: Control mechanism for electric motors
IPC: H02K11/00
Filed: 1936-04-27
Abstract: 475,963. Automatic control systems. CHICAGO FLEXIBLE SHAFT CO. April 27, 1936, No. 11944. Convention date, June 3, 1935. [Class 38 (iv)] [Also in Group XXXVII] Speed.-A control switch for an electric motor driving, for example, a household mixer, includes a rotatable member 46, Figs. 2 and 3, driven by the motor and carrying co-operating contacts 57, 58, the contact 57 being mounted on a leaf spring 56 carried by a weighted arm 53 pivoted at 52, and tending to leave the contact 58 as the spring 56 flexes with increasing motor speed, and the arm 53 rotating under the influence of centrifugal force to keep the contacts closed at predetermined motor speeds. The switch controls a resistance 42 and condenser 40, Fig. 13, in the motor circuit to maintain the motor speed constant at a value determined by the extent to which the arm 53 is permitted to rotate by a cam 68 which engages a button 55 on a projection 54 of the arm 53. The cam 68 is adjusted by a knob 26 which has a cammed groove 93 engaging a pin 94 which rotates a spring-biassed bifurcated lever 79 engaging rings 73 of a sleeve 67 sliding on the extension of the motor shaft and having projecting fingers forming the cams 68, 69. The elements on the member 46 forming the switch mechanism are duplicated on the opposite side of the motor shaft 29 for balancing only, the duplicate mechanism having no contact. The knob 26 on its inner face 96 has a detent 98, Fig. 12, which, in the position of the knob, permits a spring switch blade 43 to open contacts 45, 46, in the motor circuit. The switch contacts 57, 58 are connected to conducting rings 49, 51 on the member 46 which contact with spring-pressed contact brushes 35, 36, carried on a partition 27 of the motor casing. Upon rotation of the knob 26 from its off position, the contacts 44, 45 in the motor circuit are closed to start the motor and, depending upon the position to which the knob is moved, the cam 68 limits the extent of rotary movement of the arm 53 about its pivot 52. This determines the constant speed at which the motor is maintained.

Filed: 1922-04-28
Abstract: 179,923. Schindler, W., (Assignees of Fradet, C.). May 11, 1921, [Convention date]. Channels in bearings and rotary pumps.-The leading edge c, Fig. 2, of each vane a of a rotary machine is bevelled at e, g, the angle x' being such that it is greater, for all the positions of the vane, than the angle x between the normal to the vane and the tangent at e to the periphery d of the stator. In a modification, the surface b, e, g is replaced by an inscribed curved surface as shown in Fig. 3. A pressure film of oil between the friction surfaces is thus created, which pressure, increasing with the speed of rotation, tends to balance the centrifugal force of the vanes. The Specification as open to inspection under Sect. 91 (3) (a) describes also a bearing provided with ribs and grooves, the leading edge of each rib being bevelled so as to produce a film of oil between the bearing-surfaces. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in Receivers for Wireless Signals.
IPC: H04B1/16
Filed: 1917-09-01
Abstract: 128,673. Marconi's Wireless Telegraph Co., and Franklin, C. S. Sept. 1, 1917. Wireless t e l e - graphy and signalling.-In an interference receiving- arrangement for wireless signalling systems employing a high wave-frequency, for example 30,000,000, the frequency of the local oscillations is varied continuously a n d rapidly above and below the wavefrequency, so as to give a note in the receiver corresponding to the number of times per second that the frequency of the local oscillations is varied. With high wave-frequencies, a slight variation of frequency, either in the transmitted wave or in the local oscillations, renders the interference note variable and unintelligible, whereas the present system ensures a definite reception note. The Figure shows a known form of interference receiver, in which an oscillatory circuit L, C is connected across the plate and filament of a vacuum tube, and is also coupled to the aerial coil N and to a coil in the grid-filament circuit. A second aerial coil R is coupled to the receiving- circuit. The frequency of the locally-produced oscillations is determined by the capacity and inductance of the circuit L, C, and, in the example shown, the capacity is varied in a rapid and continuous manner by placing a variable capacity a, b in shunt to the condenser C. The variable capacity comprises fixed plates a and segmental plates b rotated at high speed, for example to give 1000 variations per second. The extent of the variations may be one-half per cent, or 150,000 above and below the normal frequency. The frequency of the interference note thus varies from zero to 150,000 during each thousandth part of a second. The audible part of this range affects the telephone and causes it to emit a note having a frequency of 1000 per second. The variable capacity may comprise plates supported on a vibratory reed; or a continually-varying inductance may be employed. The receiving- circuits, including a crystal or valve detector, may be coupled to the coil R.

Abstract: 1,013,638. Hydraulic turbines. DOMINION ENGINEERING WORKS Ltd. March 25, 1964 [April 8, 1963], No. 12584/64. Heading F1T. A Francis hydraulic turbine comprises a runner having a runner band 36, Figs. 1A and 2, a static structure 19 spaced from the runner band by an annular gap 16, a sealing face 25 of a distributer ring 14 co-operating with a sealing face 24 of the runner band and spaced therefrom such that leakage water may enter the space 16, a pipe 20 for supplying air to space 16, and a baulk ring 21 located in space 16 to provide a path for fluid flow around and below it to a draft tube 17. The baulk ring 21 is spaced from the static structure by webs 26, Fig. 3, between which are openings 27 providing an extension of the path 28 by which leakage water escapes to the draft tube 17. The baulk ring serves to discourage the turbulence caused by recirculation of leakage water in an axial direction in space 16. The vertical dimension of the openings 27 may be one half of the vertical distance of the lower edge 30 of the runner band from the static structure. The air supplied to space 16 serves to keep the periphery 38 of the runner band free from contact with the rotating annulus 34 of leakage water and the clearance 35 between the runner band and the baulk ring is small to impede escape of this air.

Title: Improvements in and relating to Digital Computers

IPC: G06F9/42
Filed: 1968-03-15
Abstract: 1,159,330. Branch instructions. BURROUGHS CORP. 15 March, 1968 [17 March, 1967], No. 12586/68. Heading G4A. Before a subroutine of a master control programme is performed as a result of detecting a branch instruction in an object programme a check is made that an address word associated with the sub-routine and identified by the address part of the branch instruction contains a flag digit. As described, the main core memory 1 (Fig. 2, not shown) of a digital computer is divided between a plurality of object programmes 0 1 -0 4  and a master control programme MCP which includes a number of sub-routines SR1-SRN and a test routine RDSR. Each subroutine has associated therewith an address word storing the start address of the subroutine and a flag digit which is a unique code. On decoding a branch instruction in instruction register 7 (Fig. 1), the contents of a comparison register 8, instruction counter 5 and base/limit register 6 (defining upper and lower memory limits of the current programme) are passed to a register 3 from where they are written into the memory 1 at an address contained in an interrupt storage address register 43. The information thus stored relates to the current object programme and provides means for returning thereto after completion of the branch routine. The address part of the branch instruction is then transferred to memory address register 4 whereby the address word of the required sub-routine is read from memory 1 into register 5 by way of register 3. A flag digit check circuit 44 then checks for the presence of said unique flag digit code and, assuming this is present, signals sequence control circuitry 12 for the performance of the subroutine to start at the address defined by said address word. If the flag digit is not present, the test routine RDSR is called in and further performance of the object programme concerned prohibited. Provision is also made for interruption of an object programme e.g. by a peripheral device in a manner similar to the above according to the states of flip-flops 9-11.
