Abstract: 344,859. Weft feeler arrangements for looms. VALENTIN, C., 20, Arminstrasse, Stuttgart, Germany. Dec. 12, 1929, No. 38095. [Class 142 (iii).] The feeler blades a shown in plan view in Fig. 4, which contact with a metal portion on the bobbin when the weft is substantially exhausted and thereby close an electric circuit controlling the weft-replenishing mechanism, are acted upon by springs b<1> in recesses in a carrier a detachably secured by a clamping screw f and member c in a holder c<1> on a spindle g in an arm h. If the feeler blades are engaged on one side or the other, for example by a shuttle entering late into the shuttle box, they are pushed to one side with their carrier &c.. the spindle g turning against the action of springs i whereby damage to the blades is prevented. In a modification described, the spindle is fast to a part controlled by two springs and movable bodily. The holder c<1> has terminal plates c<2> connected by screws d to leads c<3> and slidably contacting with plates e secured to the carrier by screws e<1> screwing into metal plugs e<2> contacting with the springs bl.

Title: Improvements relating to feed water regulators for boilers and the like
IPC: F22D5/10
Filed: 1929-12-13
Abstract: 339,793. Cockburns, Ltd., and Mac- Nicoll, D. Dec. 13, 1929. Valves controlled by pilot or relay valves.-A boiler-feed regulator of the kind actuated by fluid pressure under the control of a float-actuated balanced auxiliary valve is fitted with external indicating means and is so arranged that the stuffing box associated with these means is only subject to low exhaust pressure. The main valve 6 has seating surfaces 5<1>, 5<2> adapted to co-operate with seats on a ported cage 7, and is formed integrally with a pair of pistons 12, 18. The piston 12 works in a chamber 13 formed in a cover 14, while the piston 18 works on a cylinder, formed in a two-part cover 20, 21 isolating the valve chamber fnom the float chamber. The auxiliary valve 5 co-operates with a renewable seat housed in a recess in the piston 18 and is balanced by a plunger 27 subject to the pressure existing below the valve. Inlet, pressure passing through a passage 26 in the valve member leaks past the piston 18 to the actuating chamber. When the auxiliary valve is seated, pressure builds up in this chamber to close the main valve. When the auxiliary valve is unseated, pressure is exhausted through passages 23, 23<1> to the chamber 13, which is connected by a passage 24 and pipe 25 to a region of low pressure. The actuating float 4 for the auxiliary valve is adjustably secured to a screwed rod 46 carried by a block 45 pivoted to a lever 41 carried by a ball bearing 42 and counterweighted by a weight 62. The float is secured to a polygonal spindle 48 working in a socket 50 adapted to be rotated in a bracket 52 by a hand wheel 53 to vary the position of the float, the setting of which is indicated by a pointer 56 having a screw engagement with the pocket and co-operating with a scale. 60. The lever 41 is connected by a link 39 with a pair of arms on a shaft 33 having a third arm 32 bifurcated at the end to engage pins 31 on the auxiliary valve. Each end of the shaft 33 passes through a pair of chambers, the inner one of each pair being connected to a region of low pressure through a passage 35, while the outer ones are supplied with water through passages 36. A testing-lever 66 engages a slot in the link 39. The main valve may be positively moved to the open or closed positions by a screw 79 and nut 78 provided with pins 77 engaging slots in the end of a lever 72 pivoted at 74 and engaging a slot 71 in a stem 16. The stem 16 is secured to the smaller piston and passes through a stuffing box 15. The lever 72 may be secured in its mid position by a pin 85. An indicating pointer 7 co-operating with a scale 90 is pivoted at 86 to the end of the spindle 16. Specification 326,100 is referred to.

Abstract: 1,199,415. Card indexes. TWINLOCK Ltd. 25 Aug., 1967 [2 Sept., 1966], No. 39370/66. Heading B6E. A device for holding cards in overlapping formation comprises a pair of spaced parallel guides 12, and a number of bridge pieces 14 slidable along the guides, the bridge pieces being constructed so that when two of them abut they define between them a slot in which a card 22 can be received with projecting ears 23 at the ends of its upper edge supported on the ends of the slot. Each bridge-piece 14 comprises a transverse part 15 with flanges 16, the flanges having ridges 17 which engage grooves 13 in the guides 12.

Title: A re-inking device for individual porous printing elements
IPC: B41K3/56
Filed: 1961-11-03
Abstract: 920,599. Inking-apparatus. NATIONAL CASH REGISTER CO. Nov. 3, 1961 [Jan. 23, 1961], No. 39376/61. Class 100 (2). Porous printing plates 24 of the type used in the label-printing machine of Specification 724,295 are re-inked in a device comprising an ink pad 34, Fig. 5, located in a tray 21 which is slidably insertable into an open-bottomed case 20, Fig. 1. The case carries a plate holder 44 manually depressible against spring pressure by actuation of a plunger 37 to bring an inserted plate 24 having a porous stamp portion 27 into contact with the pad 34. The tray 21, Fig. 3, has a cover 31 apertured at 32 to allow contact between the plate and the pad. To ensure the proper positioning of the plate 24 within the holder 44 before a re-inking operation a spring- loaded slidable latch 51 is provided in the case 20 which is engaged by the inner end of the plate when it is fully inserted in the holder. Until the plate is thus positioned the latch engages the holder, thereby preventing any downward movement should depression of the plunger be attempted. A further locking arrangement in the form of a V-shaped notch 33 on the tray 21 engageable with a spring-loaded arm 57 in the case 20 ensures that the tray is fully positioned in the case before an inking operation. Movement of the arm 57 into the notch 33 when the tray is thus positioned removes a pawl 62 from the path of the latch 51, thus allowing the latter to be moved on full insertion of the plate into the holder. Attached to the holder 44 is a wiper blade 64 which wipes off any excess ink that accumulates on the raised characters 28 of the plate stamp portion 27 as the plate is withdrawn from the holder. To prevent the plate 24 from leaving the holder 44 due to the pressure of the latch-loading spring 54, the plate has a shoulder 68 (not shown) which engages a bent-in flange 42, Fig. 5, upon the downward movement of the holder into inking position. The stamp portion 27 is of porous rubber whilst the pad is of polyurethane foam.

The printing surface 23 Fig. 1 is exposed uniformly by a lamp 35 and through the negative 21 by a lamp 25. The partially transparent mirror 28 has n% transmission when n >50, with the result that equal quantities of light falling on surface 23 from lamps 25 and 35 will produce outputs from the photoresistor 30 which are in the ratio (100 - n / n)<SP>2</SP>. Initially, switches 53 and 44 are closed, the paper 23 exposed uniformly and the condensers 42 and 43 charged by the photoresistor current. After a predetermined time switches 53 and 44 are opened and switch 50 closed. Printing proceeds and condenser 42 is charged until a thyratron 45 fires to open a relay 49.
