Abstract: 646,248. Gauging-apparatus. MAURER, J. July 2, 1948, Nos. 17919 and 17920. Convention dates, July 2, 1947 and June 21, 1948. [Class 106 (ii)] A bore comparator comprises a feeler whose movements are transmitted to a dial gauge through a spindle, the feeler and spindle each being integral with a rack engaging a common pinion. An extension 3 is screwed into the casing of a dial gauge 1 and is formed with a hole 5 in which freely slides a rod 6 pressed by a spring 8 against the plunger 9 of the dial gauge, a stud 18 preventing rotation of the rod 6. A feeler 10 slides in a guide at rightangles to the rod 6 and both feeler 10 and rod 6 are formed with racks meshing with a common pinion 17, the dial gauge spring overcoming the spring 8 to extend fully the feeler 10. Interchangeable parts 20 formed with stops 23 of different sizes are provided and further centring means comprise stops 31 on legs 30 symmetrically placed with respect to the feeler and formed in a plate 24 hinged at 25 and urged counter-clockwise by a spring 26. In a second embodiment, Figs. 5, 6 the stop 23 is supported by a part 34 screwed into a sleeve 35 slit at 36 and secured to the extension 3 by screws, the part 34 being adjusted by a knurled knob 39 and locked by a screw 38 drawing the halves of the sleeve together. The comparator is centred by a plate 41 having two cylindrical guides 43 sliding in holes symmetrically located each side of a cylindrical part 42 with springs 44 urging the plate 41 outward and pins 45 to limit this movement, three-point contact being made by the stop 23 and in curved rims of the plate 41. Fig. 7 shows a comparator similar to the first embodiment but having the interchangeable member 20 in the form of a gauge block held by a screw 22. A flange 50 with U-shaped part 51 embracing the extension 3 can be clamped in any position by means of a knurled head 53 controlling an eccentric 52. To set the comparator to measure a particular dimension set up on a micrometer, a button 32 is pressed to free the rod 6 temporarily from the plunger 9, the flange 50 is clamped near the block 20 so as to hold the centring means 31 retracted and the comparator is introduced between the anvils of the micrometer until a face 55 of the flange 50 abuts the anvils and is oscillated slightly until the dial reads the highest value corresponding to the required dimension. The comparator is then introduced into the bores to be gauged either with the flange clamped to set the depth the measure is to be taken or the bores are gauged without using the flange, the comparator being slightly oscillated to ensure a reading on a diameter.

Title: Improvements in and relating to hydraulic brake systems
IPC: B60T11/228
Filed: 1936-07-01
Abstract: 477,772. Fluid - pressure brakes. WEIHE, H. K. July 1, 1936, Nos. 18302 and 18303. Convention dates, July 1, 1935 and March 2, 1936. [Class 103 (i)] An hydraulic brake, more particularly for motor vehicles, comprises a refilling device in the form of a pump which is operated by the brake pedal to draw excess fluid from a reservoir during brake application, and is operated by a spring to force this fluid into the system during brake release, the excess fluid finally escaping back to the reservoir through a valve which determines 'the initial pressure in the system. The auxiliary pump comprises a piston 8, Fig. 1, in a cylinder 7 on the master cylinder 1. The piston is raised by a cable 11 connected to the brake pedal 4 on brake application and draws fluid through a check valve 15 from a reservoir 14. On brake release the piston 8 is forced down by a spring 10 and forces fluid through a passage 19 and valve 16 to the master cylinder. Excess fluid escapes past a check valve 17, the spring tension of which may be adjusted from the driver's seat, and through a tube 221 which opens near the highest point of the reservoir to allow air bubbles to escape. The cable 11 may be attached to a spring-pressed valve passing through an aperture in the piston 8 and seating underneath it. This valve allows air to escape from below the piston. In a modification, the master and pump cylinders are formed parallel with the reservoir between. In this modification the lip of a flexible packing is used in place of the valve 16. In a further modification, the pump may also be operated by depression of the clutch pedal and also by connection to other moving parts of the vehicle. The Specification as open to inspection under Sect. 91 comprises also a modification in which the pump piston 29 Fig. 3 (Cancelled), is integral with the master piston 27 and draws fluid from the reservoir by a pipe 35, the fluid being forced through a central passage 32 past a valve 34 on the release stroke of the piston. This subject-matter does not appear in the Specification as accepted..

Abstract: 796,385. Statistical apparatus. SPERRY RAND CORPORATION. June 13, 1956 [June 13, 1955], No. 18335/56. Class 106 (1). Sensing apparatus for record cards comprises means for feeding the cards 51, Fig. 3, to bring the rows of data positions in succession under the sensing brushes 87, photo-electric means 90 for detecting a card fed to sensing position and for initiating a succession of electric pulses for application to the sensing brushes, these pulses being synchronized by a magnetic disc 82 rotating in time with the card feeding rollers so as to coincide with the data positions. As the leading edge of the card passes over the photo-cell 90 a pulse is generated and passed through gate G100 both to recording head 83 and to the sensing brushes 87 to coincide with the passing of the first row of data under the brushes. The magnetic mark recorded by the head 83 is read by head 84 and passed through gate G109 back to the recording head and also to the brushes 87 where it coincides with the second row of data. The cards are fed from a hopper 17, Fig. 2, by a knife 21 on picker arm 22. The arm is oscillated by a cam 26 and may be latched in one extreme position by a latch 28 controlled by a magnet 29. The cam-shaft is driven by a belt from motor 25, the belt also passing over pulleys serving to drive the feed rollers 47, 48 for the cards. The magnetic disc 82 is fastened to the middle lower roller shaft 44. On emerging from the last pair of rollers the card is taken by grippers on drum 54 and carried round to be stacked on plate 62. If an error is detected in any card the lever 67 is swung into the path of the card to draw it out of the grippers and cause it to fall into the error pocket 14. The sensing brushes 87 are mounted on a cross-bar 86 of insulating material, there being eighty brushes, one for each column of the cards. All brushes are pulsed by the circulating sprocket pulse and where the pulse coincides with the registration of a brush with a card perforation, the pulse is transmitted to a contact strip under the card. In another form the picker knife is modified by the provision of a suction chamber adapted to grip the card adjacent the knife edge. A suction chamber is also provided across the width of the feed hopper adjacent the exit throat. Slots are provided in the floor of the hopper so that the card is drawn downwardly and passes through the throat without jamming. Specification 793,339 is referred to.
