Title: Improvements in or relating to counting apparatus
Filed: 1928-11-17
Abstract: 325,480. British Tabulating Machine Co., Ltd., (Assignees of Ford, E. A.). Nov. 19, 1927, [Convention date]. Divided on 300,909. Statistical apparatus.-In a record -card - controlled counting machine having units counters for the card-hole positions connected individually with the card-reading device, a reject counter has a connection (182), normally effective, which transmits at the end of each card cycle an impulse to the reject counter, there being controlling means (183) which operate, when a counter has been actuated by a hole being read, to disable the said connection to the reject counter. The apparatus described is the same as that described and shown in Figs. 3, 9, 15, 16, 18, 21, and 22 of Specification 300,909. When a card-hole is read by the brush a circuit is closed from positive line to 43, 44<1>, 181, 182, 183, 184, 185, card-lever contacts 186, to negative. Simultaneously, a circuit is made from 182 to common bar 188, a units counter magnet 107 and segment 179 corresponding to the hole under the brush, 180, 189, to 186. Energization of 183 unlatches 192 to open contacts 182. Late in the card cycle a cam rotated by the sorter motor restores part 192 to close contacts 182. Normally, therefore. reject counter magnet 107 is energized when the rear edge of the card leaves the brush and the latter meets the base contact roller 43. If a hole has been read, however, contacts 182 are open and the reject magnet is not energized. Hence this magnet will count all cards not counted on other units counters 9 - - 0, X, or E. Specification 284,241 also is referred to.

Abstract: 678,606. Copy-turning. MASCHINENFABRIK ANDRITZ AKT.-GES. Jan. 8, 1951 [Jan. 7, 1950], No. 541/51. Class 83 (iii). [Also in Group XXIII] In a method of re-machining pulleys, particularly rope pulleys, by turning or grinding, the tool - holder is maintained in correct relative position to the work (despite eccentric and lateral distortions thereof) by a feeler guided by the profile to be machined, the feedmotion of the tool being effected independently of the movement controlling the tool-holder. A pulley 11 may be trued in situ and driven by its ordinary rope or may be mounted in a lathe &c., for machining. The tool 3, Fig. 2, is carried in a holder on a compound slide 6, 7, and the lower member thereof is circularly adjustable on a further slide 5. The feeler 10, Fig. 3, in the form of a roller, with contact faces arranged to engage the base of the pulley groove, is carried by the slide 5, Fig. 2. This slide is maintained with the feeler against the side wall of the pulley by a weight on a cord and pulley 14, 15, the weight being placed on the side of the slide to hold it against the reaction of the tool. A further slide 4 below and at right-angles to slide 5 also has a pulley, cord, and weight to hold the feeler in the bottom of the pulley groove. Spring, hydraulic, or pneumatic pressure means may be used in place of the weight and cord. To protect the feeler from falling shavings a sheet-metal screen may be provided, or the shavings may be blown away by compressed air.

Title: Pneumatic braking apparatus, in particular for vehicles
IPC: B60T13/36
Filed: 1929-01-08
Abstract: 305,127. Skoda Works Plzen. Jan. 31, 1928, [Convention date]. Fluid-pressure.-In pneumatic braking apparatus for vehicles &c. the compressed gas is supplied directly from the compressor to the brake cylinders without the intervention of a reservoir and in order that full braking pressure may be obtained with few revolutions of the compressor, the capacity of the compressor and spaces on that side of the control valve is not less, that onefiftieth of that of the brake cylinders and piping. When the pedal 8 is depressed to apply the brakes, the clutch 4, 6 is engaged to drive the compressor 1 from a running part of the vehicle and the valve 10 is actuated by the lever 9 and elastic pull rod 11 to connect the compressor to the pipes 3 leading to the brake cylinders. The braking pressure established is determined by a spring-loaded valve 2 which discharges the compressed air into the atmosphere when the spring is overcome. The pressure of the valve spring and thus of the compressed air in the system is increased by the lever 9 in accordance with the pressure applied to the pedal 8. When the pedal is released the pipe 3 is connected to the atmosphere through the valve 10. The cylinder capacity of the compressor 1 may for example, be .33 Litre and that of the brake cylinders, valves, pipes &c. may be 1.66 Litres.

Abstract: 844,580. Dental handpieces. KALTENBACH, A., and HOFFMEISTER, E. Jan. 8, 1959 [Jan. 9, 1958], No. 774/59. Class 81(2). A handpiece for a dental drill has an air turbine interchangeably mounted adjacent the nose part of the handpiece. An axial flow turbine is used in the embodiments described and in one form the rotor 8 is mounted on a spindle 7 carried in bearings 5, 6 and having a friction grip chuck 33 at its outer end. Air is directed into the rotor through oblique holes 16 in a fixed plate 15, the air being admitted through radial holes 28, a central tube 23 and a connecting stub 26. After passing through the rotor the air passes out through a second perforated disc 13 and radial holes 29 to the annular space 18 and thence through the interior space 30 of the handpiece to discharge orifices 31. A spring- loaded push rod 35 passes centrally through the handpiece and is used to engage a short rod 43 to press a burr out of the chuck 33. If the end cap 24 is unscrewed, the turbine may be drawn out bodily through the rear of the casing. In the construction shown, the rear of the turbine casing is centred by the end of the air tube 23 engaging a conical recess in a collar 20 but in a modified form there is no collar but the end of the tube passes into the centre hole of the disc 15 to centre it. A further form is also described in which the turbine rotor and chuck are carried in a ball bearing at each end of the assembly. In this case the air is admitted through the outer annular chamber of the handle and the exhaust air passes out through the central tube.

Class 7(iv) [Also in Group XXXV] In an electric spark ignition apparatus comprising a pair of systems each including a condenser b, Fig. 1, a rectifier d through which the condenser can be charged and a control spark gap f, the two systems are adapted by their inter-action to ensure simultaneous spark discharges therein. The secondary winding a, of a transformer is connected to the pair of high-tension systems each of which has in parallel therewith the condenser b whilst between one end of the winding and each condensed is arranged the rectifier d so that the condensers receive alternate charges; in series with each condenser b and the ignition gap e is the control gap f. The two circuits are coupled by coils h, forming a mutual inductance; in order to effect simultaneous discharges of the ignition gaps; a condenser g connected across both gaps e may be used instead of, or in addition to, the coils h. The primary winding i, is in two parts each of which has a centre tapping j, both parts being connected through an interrupter to a source of cur- .rent. The interrupter comprises a pair of movable contacts m and two pairs of fixed contacts p so that current is alternatively supplied to the halves of each winding. Each condenser b, is progressively charged until the breakdown voltage of the control gaps f is reached, the discharge across these gaps causing simultaneous sparks at the ignition gaps e. A high resistance may be connected across each ignition gap and two identical interrupters may be used, the total current being shared between them. In a modification, the coils of the mutual inductance are dispensed with and replaced by inductances for prolonging the duration of the discharges; an inductance is also connected in the line from the other side of the secondary winding. The controls gaps are arranged adjacent each other so that a discharge across one will ionize and cause breakdown of the other. The primary winding comprises one coil with a centre tapping, and the interrupter is as shown in Fig. 1. the two. pairs of contacts sharing the total current whilst resistances are placed in series with the contacts. In another modification, two interconnected transformers are employed, and a mechanical or electromagnetic interrupter m, Fig. 4, is associated with each primary winding i; each condenser b, is connected to one end of secondary winding a through a rectifier d and each of the outer lines in the two secondary circuits embodies a choke u and the common line includes a choke c.
