Abstract: 196,612. Aktiebolaget Atlas Diesel. April 19, 1922, [Convention date]. Regulating.-In a governing-device wherein the fuel pump is provided with an overflow by-pass controlled by a valve the time of opening of which is varied by the governor, the valve is arranged so that air present in the charging passage gathers at the valve and escapes therethrough. The pump plunger 4 is actuated by a bell-crank 6 and a tappet rod 7 passing through a guide 8, and supplies fuel to the cylinder through a passage 11. The overflow by-pass 25 is controlled by a lift valve 12 through which air and surplus fuel escape when it is opened against the pressure of a spring 15 bv an arm 17 on the bell-crank 6. The time of opening of the valve 12 is varied by means of a wedge 18, which is moved along the arm 17 by the governor through a lever 20, rod 21, and a lateral arm 22 on the guide 8, which is rotatably mounted and ccnnected to the governor. In a modification. Fig. 2, the valve 12 is allowed to open by a lever 30 connected to the bell-crank 6 and eccentrically mounted at 29, the position of the eccentric being varied by the governor. Any air which is forced past the valve 12 is prevented from returning at the beginning of the suction stroke of the pump, by a valve 32. In another form, the valve 32 is omitted, its function being performed bv the valve 12, which is then fitted with an additional spring arranged between the valve stem and the actuating-plunger 31.

Abstract: 720,317. Trueing grinding-wheels. PRECISION DIAMOND PRODUCTS, Ltd. April 28, 1953 [April 28, 1952], No. 10632/52. Class 60. Apparatus for forming a convex or concave profile on the peripheral surface of a grinding- wheel G comprises a rotary member 16 mounted for rotation about an axis CA, a tool holder 3 carrying a tool 4 and provided with a pivot bearing 10 connected to the rotary member, means for adjusting the pivot bearing eccentrically with respect to the axis CA, and means interconnecting the rotary member and the tool holder whereby during traverse of the tool tip the latter is always substantially in alignment with the axis of the pivot bearing which moves in a predetermined path. The pivot bearing forms part of a slide radially adjustable in relation to the member 16 by a screw 13 in engagement with a nut 14 forming part of a shaft 15 which receives a nut 17 to lock a cap 18, carrying a handle 22, to the member 16, a key 18a also being provided. A second rotary member 27 driven at half speed through a ball-bearing drive 26 is connected by a pin 36 and slot 38 with the tool holder 3 so that when the handle 22 is rocked between adjustable stops 39 the tool shank moves through only half of the angular distance traversed by the tool point to enable concavities of smaller radius than the tool shank to be formed. To set the bearing 10 to the required eccentricity a dial gauge is inserted in an aperture 29 with its plunger in contact with a face 32. The eccentricity is determined by the radius of the surface to be formed and the amount by which the tool 4 is adjusted in its socket 5 to compensate for the radius of its tip. The apparatus may be used as a simple radiusing device by removing the pin 36 and clamping the holder 3 -to the bearing 10 by means of a screw 43. The interstices between the moving parts are filled with grease to exclude dust. The tool 4 may be diamond tipped. The Provisional Specification describes an arrangement in which the axis CA is vertical and the rotary member 16 is turned through toothed gearing.

Title: Improvements in and relating to signal or alarm devices for small scale or model rail traction systems
IPC: A63H19/34
Filed: 1936-04-15
Abstract: 469,570. Toy railways. STRONG, F. G. April 15, 1936, No. 10820. [Class 132 (iii)] A signal or alarm device for small scale rail traction systems comprises an electrically - operated signal or alarm associated with switching means adapted to complete the circuit of the signal or alarm as a consequence of a vehicle passing over a predetermined part of the track of the system. In the construction shown in Figs. 1 and 5, a contact shoe on a train effects contact between the plate 3 and the middle rail 4 to energize the solenoid 10 and cause the disc 25 to move to the left and the contact plate 23 to be connected with the plate spring contact 21 to complete the circuit of the blue signal light 37 on the lamp standard 36. The contact shoe on the train later effects contact between the plate 15 and the rail 4 to energize the solenoid 13 and cause the plate 23 to be moved to the right to connect with the plate spring contact 22 and complete the circuit of the red signal lamp 38. In the construction shown in Figs. 6 and 11, a train moving on to the length 43 of track across the gap 42, bridged by insulating material of wood, bamboo or rubber, will cause current to flow from the length 41 to the length 43 through the solenoid 45 and as a consequence the core tube 48 is lifted and the spring contact 49 is allowed to engage with the contact 50 to complete the circuit of the alarm signal 60. When the train moves off the length 43 across the gap 42a on to the length 41, current ceases to flow through the length 43 and the alarm signal becomes inoperative. Reference has been directed by the Comptroller to British Specification 228,550, [Class 132 (iii)], and U.S.A. Specifcations 1,846,223, 1,857,933, and 1,865,278.
