Title: Improvements in or relating to precision gauges
IPC: G01B3/38
Filed: 1943-02-02
Abstract: 562,804. Gauges. PITTAR, E. G. F. Feb. 2, 1943, No. 1686. [Class 106 (ii)] A precision gauge or comparator comprises a rigid frame or stock fitted on one side with a fixed but adjustable anvil and on the other side with one or two fixed but adjustable feelers or plungers and a movable plunger that is geared to a pointer or other indicator. As shown in Figs. 1 and 3 for gauging external dimensions, the body part A has an upper limb A<1>, with an anvil B that is initially adjusted by a set screw B<1> and locked by a tapered pin B<2>, and a lower limb A' fitted with three plungers C, C<1> and C<2>. The plungers C, C<1> are initially adjusted by set screws c, c<1> and locked by a tapered pin C<3>, the setting determining correct or upper dimension and the under or lower dimension respectively. The third plunger C<2> is arranged to slide between limits and is pressed upwardly by a spring C<6> within the plunger and bearing on a set screw C<7>. The lower edge of this plunger engages an angular recess in a disc D<1> mounted on a spindle D<2>. The spindle carries a pointer D that cooperates with a scale E arranged behind a window A<4> in the body part. In a modification, the setting of the anvil B is effected by a known form of micrometer fitting. A modified form of the indicating mechanism is shown in Fig. 6. In this arrangement the plunger C<2> is formed with a rack E<6> in mesh with a pinion E<5> to which is attached a toothed sector E<3> engaging crown teeth on a barrel or drum E<1> loosely mounted on the plunger. The barrel E<1> can be lifted, against the action of a spring within the drum, to disengage the teeth to facilitate the initial setting, the position being determined finally by a set screw C<7>.

Title: Door operator
IPC: E05F15/14
Filed: 1973-01-12
Abstract: 1425180 Operating vehicle doors VAPOR CORP 12 Jan 1973 [14 April 1972] 1730/73 Heading E2M A vehicle, particularily a passenger rail vehicle, has a door 24 movable between open and closed positions by an operator 20 along one side of which it passes, the operator including an upstanding mounting plate 35, on one side of which is a reversible motor 36, preferably electric, and a gear box 37, with a substantially horizontal output shaft 38 carrying a drive arm 39 on the side of the plate opposite to the motor and coupled to the door through a pivot arm 41 and a roller 45 engaging a slide 55 on the trailing edge of the door, with resilient means 47 coupling the drive and pivot arms to accommodate free movement of the door relative to the drive arm if the door is obstructed while closing. Such free movement is easiest when the door is nearly closed, as the torque arm of the lever 41 is greatest. When the door is closed the roller is in an overcentre locking position relative to the shaft 38, and the door is further locked by the engagement of a pin 65 carried by the door in fork 61 pivoted on a shaft 62 to the plate 35, and held by a locking bar 72. To open the door the lock is released by operation of solenoid 78 whose plunger 79 engages the locking bar to allow spring 80 to rotate the fork to allow the pin 65 to escape, Fig. 8 (not shown), actuating a switch 113 which illuminates an indicator lamp, and switch 114 which causes relay (115), Fig. 10 (not shown) to energise the motor. During opening cam 116 on the shaft 38 successively actuates microswitches 117, which prepares the operating circuit for the closing cycle 118, which deenergises the solenoid 78 and connects a braking resistor (119), and 122, which deenergises the motor. If the unlocking circuit fails the plunger 79 can be moved manually by means of a lever 90. This actuates a microswitch 94 to supply the motor, but if this fails then further rotation of the lever 90 causes, through pin 96, lever 97, pin 98 and lever 48, rotation of the drive arm 39 to break the over-centre arrangement so that the door can be forced open. Specification 1189950 is referred to. Reference has been directed by the comptroller to Specification 1189950.

Title: Improvements in or relating to video signal clamping circuits
IPC: H04N5/18
Filed: 1955-01-20
Abstract: 764,142. Television. FERNSEH GES. Jan. 20, 1955 [Jan. 21, 1954], No. 1746/55. Class 40 (3). [Also in Group XL (c)] Negative-going television signals applied at 1 to the grid of a cathode-follower stage 3 are restored during blanking intervals to a reference potential applied at 12 by means of a four-diode clamping circuit 4-7 actuated by positive and negative pulses at 10 and 8, and simultaneously a positive pulse is applied at 16 to the grid of a second valve 14 sharing cathode-load 18 so as to cut off valve 3 at the cathode and isolate the output across 18 from the input signal source. The circuit has the effect of eliminating from the output any disturbing signals which may be present at the grid of valve 3 during the blanking intervals despite the clamping operation. The potential at 12 is so chosen that if the amplitude of the television signal increases beyond normal white level, then valve 3 is cut off. The output from across resistor 18 is applied to terminal 23 via a rectifier 19 biased by network 20-22 so that only signal voltages within the picture range is passed and the pulses added by the action of valve 14 are eliminated. The resulting potential at terminal 23 during the blanking interval corresponds to black level and may be varied by resistor 20. A second output corresponding only to signals exceeding a predetermined level is selected by a further rectifier 24 biased by network 25-27 and applied via terminal 28 to a peak rectifier (not shown) to derive a control voltage for automatic control of the gain of a video amplifier supplying the television signal to terminal 1.

Title: Improvements in or relating to apparatus for diverting or segregating wave signals of selected, predetermined frequencies from a main wave guide carrying a plurality of high frequency waves
IPC: H01P5/18
Filed: 1940-08-14
Abstract: 545,936. Signalling through wave guides. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Aug. 14, 1940, No. 1994/42. Convention date, Aug. 24, 1939. Divided out of 545,779. [Classes 40 (iii) and 40 (v)] Apparatus for diverting or segregating wave signals from a main wave guide to one or more receiving guides contiguous for at least a portion of their length with the main wave guides, comprises a plurality of mutually spaced energy interchanging devices at the contiguous portions adapted to transfer predetermined frequencies between the guides. The Figure shows apparatus for directing signals of selected frequencies from a guide 71 to adjoining guides 69, 70. Loops in guide 71 link with the waves and are connected through holes to corresponding antennae in the adjacent guides. The sense and spacing is such that transfer is effected in the required direction at the particular frequency concerned. The devices may be so arranged that the major transfer is effected by a central element 75 associated with pairs 74, 76 and 73, 77 so spaced that the signal path in wavelengths through one element of the pair is as much longer than the corresponding path through the central element as the path through the other element of the pair is shorter. In this way a frequency discriminating filter is obtained which is capable of producing either single or multiple pass and stop bands.

Title: Improvements in material-charging apparatus for pneumatic conveying plants
IPC: B65G53/48
Filed: 1936-01-22
Abstract: 456,202. Pneumatic conveyers ; screw conveyers. MOLLER, J., 266, Gr. Bergstrasse, Altona-on-Elbe, Germany. Jan. 22, 1936, No. 2093. [Class 78 (i)] In materialcharging apparatus for pneumatic conveying-plants, the material, preferably in the form of loose fine grains, is mechanically conveyed into an annular space 20, formed between the air-jet 17 and a mixing casing 15 enclosing said jet, by means of a rapidly rotating closed worm 5, the supply of material to the worm being less than the capacity of the worm. The air is accelerated in the nozzle 17 in such a manner that no air pressure is directed against the material at the charging position, the material being fed preferably in a direction perpendicular to that of the jet axis. The jet position may be adjustable both axially and transversely, and its diameter may also be variable. Auxiliary small jets may also be provided, and the main jet may be sub-divided into a plurality of component jets. In Fig. 1, the material falls from a funnel 1 on to a plate 3 rotated by gearing 8, 9, 101, 10<11> from the worm shaft 6. The drives of the plate 3 and of the shaft 6 may be independent of one another and be regulatable. An adjustable scraper 4 feeds the material from the plate 3 to the worm. The worm is arranged perpendicularly to the jet and the worm casing 14 has an inner diameter approximately equal to that of the mixing casing 15. Fig. 2 shows an application of the invention to a machine which picks up loose material lying on the ground by means of two rotating plates 2111. An auxiliary jet 36 blows the material discharged by the worm 5 into the eddy space 28 against the nozzle 17. The air from the jet 36 is obtained from the main supply pipe 16 by a byepass, and is circulated, on its way, around the worm-shaft stuffing box 32 for cooling the box. A hood may be fixed over the pick-up end of the worm to limit its taking- up capacity. An adjustable roller 40 keeps the plates 21<11> the correct distance above the ground.
