Title: Improvement in Detonating Fog Signal Appliances for Railways and the like.
Inventor: EADON GEORGE
IPC: B61L5/22
Filed: 1917-08-10
Abstract: 117,952. Eadon, G., and Eadon, P. R. Aug. 10, 1917. Detonator apparatus.-Two detonators are fed simultaneously from vertical magazines M by one slide C moved by a lever in the signal box. The apparatus may be arranged to feed one detonator only from a single magazine. The detonators B on bases N fall from the magazine into a recess in the slide C and as the slide moves forward, a transverse bar G, with slotted upstanding lugs H, is moved by inclined faces of the guides for the slide C to hold the bases N of the detonators. The front part E of the slide C is hinged to fall as the slide moves forward. A pawl F removes spent detonators. Unspent detonators may be drawn off the rail beneath the casing by' a partial stroke of the lever. The fish-plate P has an inclined upper face to guide the detonators to the head of the rail.

Title: Prepayment Electricity Meters.
IPC: G07F15/00
Filed: 1916-08-18
Abstract: 101,535. Landis et Gyr, Soc. Anon. Sept. 18, 1915, [Convention date]. Electricity, supplying by meter.-In a prepayment attachment for electricity meters, counting- trains 2, 19 indicating respectively the total consumption of electricity and the total number of coins inserted, quantity mechanism 5, 6, and a supply switch 12 are combined together to form one removable part. A wheel nut 5, in gear with a long pinion 4 driven by the meter mechanism, traverses a threaded spindle 6, which is rotated through an elastic coupling 8 by coin mechanism 7. The spindle 6 is provided with a plain portion 17, on to which the wheel nut 5 passes if a coin is inserted and the coin mechanism operated after the maximum number of coins has been prepaid. A switch arm 12 is fixed to a mutilated wheel 11, to which are also attached a counterweight 13 and a stop 14. The rotation of the spindle 6 after the insertion of a coin effects, through a gear 10, the rotation of the wheel 11 until the toothed pcrtion 11<1> escapes from the teeth of the gear; the counterweight 13 being then in the upper position and past the dead-centre, the wheel 11 rotates rapidly until the switch arm 12 passes in between contacts 16 and closes the consumer's circuit, the wheel being retained in this position by the engagement of the projection 14 with a sliding stop 15 controlled by a spring 21. At the conclusion of the supply, the wheel nut 5 engages a projection 20 on the stop 15 and moves it to the left, Fig. 2, from beneath the projection 14, whereupon the counterweight 13 restores the wheel 11 to the normal position, shown in Fig. 1, breaking the consumer's circuit. The elastic coupling 8 permits the wheels 10, 11 to pass readily into gear. A magnet 22 prevents burning of the contacts 16.

Abstract: 582,954. Seed-sowers. PATTERSON, J. G., and DOWDING, W. J. June 26, 1944, No. 12075. [Class 6 (i)] A device for sowing seeds singly comprises a rotatable drum provided with an outlet chamber fitted with two valves, one of which opens momentarily once per revolution to admit one seed to the chamber and the other opens subsequently to permit the seed to fall to the ground. In the form shown, a seed drum 11 is fixed on a wheeled chassis capable of being drawn over the ground. Against the peripheral wall of the drum is located a chamber 21 provided, in one of its end walls 22, with a small hole 24 to which is attached a hopper 35. The hole is normally closed by a shutter 25, the outer edge of which slides over the circumference of a stationary ring 27. The ring is provided with a slot 38 at its lowest point and on reaching the slot the shutter 25 opens momentarily to admit a single seed to the chamber 21. The chamber is provided with an outlet to a delivery shoot 17, the outlet being periodically opened and closed by a steel block 20 sliding back and forth between the end walls of the chamber. On entering the chamber, the seed falls into a groove 29 in the block and is permitted to fall through the shoot 17 when the block has slid back to uncover the outlet during the subsequent motion of the drum. By the provision of a number of outlet chambers arranged to rotate in parallel planes, multi-row seed sowing may be effected.

Filed: 1922-05-01
Abstract: 193,367. Aktiebolaget Ljungstr÷ms Angturbin. Feb. 17, 1922, [Convention date]. Surface condensers.-In an air-cooled condenser, especially for locomotives, in which the steam is condensed in a number of flattened tubes or like elements, the elements are arranged in groups, which are so arranged and in which the air is so divided by baffles &c. that the crosssection of a group exposed to the air current is greater than the space between two groups through which the air-current enters or leaves the condenser, space being thus saved. For this purpose the tubes may be arranged in two rows as shown in Fig. 4, the air passing through spaces 12 between the groups 13 of the elements of the first row being guided by partitions 15, 16 among the elements of the second row, and the air passing through the groups 13 of the first row being guided by the same partitions into spaces 14 between the groups 11 of the second. Other arrangements, including one with three rows, are described. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement, shown, in Fig. 9 (Cancelled) in which the air passes obliquely to the condenser, the elements being placed obliquely to correspond, and the air being directed by baffles 18 as shown. The continuations 29 of the baffles 18 may be hinged and directed to suck air through the condenser by the motion of the locomotive, whether it is moving forwards or backwards. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in photographic shutters

Abstract: 830,263. Photographic shutters. GAUTHIER G.m.b.H., A. April 23, 1956 [April 30, 1955], No. 12385/56. Class 98(1) In a setting type shutter in which main and supplementary springs drive a master member, the supplementary spring is fully tensioned whenever the shutter is set and the exposure time is varied by a preliminary partial release of the tension in the supplementary spring so that the tension which remains in this spring is used in conjunction with the main spring to drive the master member during exposure. As shown, a pin 26 on a slide 23 may partially release supplementary spring 9 and subsequently operate the shutter. Shutter driving spring 8 and spring 9 are simultaneously tensioned by rotating master member 4 anti-clockwise about bearing 3. Lever 24 pivoted at 27 and having arm 24b in the path of pin 26 is urged anti-clockwise by spring 25 and latches the master member 4 in the set position by engagement with arm 4c. Cam 16 is rotatable on arbor 17 to set the shutter speed so that, when pin 26 releases lug 14c on lever 14, spring 9 is released to the extent required to bring pin 15 into contact with the periphery of cam 16. The cam 16 is so shaped that, for slower speeds, the tension in spring 9 is completely released and the shutter is driven by spring 8 alone. A known escapement mechanism may be set by further cams on arbor 17 and it may engage projection 19 rotatable with shutter blade 7 to control the exposure time. A toothed portion of master member 4 meshes with toothed segment 6 to drive the shutter blade 7. A known cover blade system is operated by slide 23. In another form (Fig. 2, not shown) lug 14c is omitted and a modified lever 24 having an arm similar to arm 24b of lever 24 is mounted on pivot 27 and is actuated by pin 26. A lug is provided on arm 14a of lever 14 and co-operates with a pin provided on modified lever 24. The shutter is set and released, in known manner, by spring actuation of member 20 mounted on pivot 22 fixed to slide 23. The cover blade mechanism may alternatively release the spring 9.
