Title: Improvements in the cleaning of filters
Filed: 1936-03-13
Abstract: 473,480. Filters. CANDY, F. P. March 13, 1936, No. 7556. Addition to 437,275. [Class 46] The arrangement for cleaning filter-beds comprising a layer of sand on a supporting layer of coarser medium by a simultaneous air scour from a pipe reticulation in the sand and a water upwash from a pipe reticulation in the coarser medium, as described in the parent Specification, is provided with means for flushing away any sand which enters the airsupply pipes. As shown in Fig. 1, air-supply pipes d extending outwards from a header g are connected at their ends to conduits m, n, one or both of which are provided with a valved outlet through which sand in the air pipes is flushed by water, supplied either through the header g or one of the pipes m, n, or entering through the perforations of the pipe d. Air may be supplied to the pipes d through the conduits m, n. The header g may be provided with a flush outlet. Alternatively, the ends of the pipes d may be turned down and left open, as shown at the right hand of Fig. 2, or turned down and connected loosely to a pipe P, as shown at the left hand of Fig. 2, the flush water being supplied through the header g. A further modification is described in which the central header g is omitted, the conduit m has downwardly-turned open ends and the conduit n has one downwardly-turned end with a non-return valve and a fluid-discharge valve at its other end, both conduits m, n having connections for the supply of compressed air. With this arrangement there need be no independent supply of flushing water as water will enter the conduit m from the bed and sand will be flushed away through the conduit n.

Title: Safe deposit box lock
IPC: E05B35/12
Filed: 1962-02-27
Abstract: 993,243. Locks. R. T. ELLIS. Feb. 27, 1962 [Feb. 27, 1961; Sept. 29, 1961], No 7595/62, Heading E2A. A lock for a safe deposit box in which a customer key and a guard key are used comprises a housing, a bolt 45 movable between extended and retracted positions, a first key nose 25 extending within the housing, a plurality of tumblers 70 movable upon operation of a key in the first key nose between a first position in which retraction of the bolt is prevented and a second position in which retraction of the bolt is permitted, and interference means acting between the bolt and the tumblers and being movable to one position in which the bolt, during assembly of the lock, can be moved to its retracted position whilst the tumblers remain in their first position, and movable to a further position in which the bolt, upon subsequent operation of a key in the first key nose, can be moved to its extended position and thereafter cannot be retracted unless the tumblers are first moved to their second position by operation of a key in the first key nose. To retract the bolt 45, a guard key is first inserted into the nose 25 and rotated to engage the edges 85 of some of the floating primary tumblers 70 and to lift them so that their slots 102 are aligned with the pin 99 of a spring-loaded lever 95. The pin 99 springs into the aligned slots 102. A second guard key is inserted into the nose 25 which engages in a reset cam 106 and is rotated to align the remaining primary tumblers 70 so that the pin 99 springs fully into all the slots 102, causing the lever 95 to pivot and draw its blocking end 100 out of alignment with the secondary bolt lug 87 (see Figs. 1 and 5). The customer key is then inserted in the nose 24 and rotated to lift the tumblers 70, through their engagement with secondary tumblers 75, to position their slots 74 opposite the primary lug bolt 48. On further rotation of the customer key the cam plate 124 engages with the projection 128 of the bolt 45 to retract it. To lock the bolt the customer key is rotated anticlockwise, the cam 124 engaging in the surface 131 of the bolt 45 to re-extend the bolt end 46; during this motion the primary tumblers 70 are lowered. The guard key is rotated anticlockwise causing the reset cam 106 to engage the surface 116 of trip dog 110 to press it against the stop 112. Movement of the stop 112 causes the lever 95 to pivot and retract the pin 99 from the slots 102, thus moving the blocking end 100 into the position in Fig. 3 to prevent movement of the bolt 45. The tumblers 70 are provided with randomly spaced holes 140 so that the resonance characteristics differ. During assembly of the lock, when the cover plate is removed, the bolt release lever 95 is pivoted clockwise and the bolt 46 retracted manually so that a rod 101 rides over the surface 138 of the bolt extension, simultaneously bolt lug 48 pivots anticlockwise and rests on the tumblers 20 held by a spring 58. Specification 993,242 is referred to.

Filed: 1952-03-25
Abstract: 707,028. An air treating device of the liquid-container-wick type. DETSINY, R. Nov. 24, 1952 [March 25, 1952], No. 7692/52. Class .81(1) An air treating device of the liquidcontainer-wick type has a closure member 3 for the container mouth and an. elongated frame which depends from the closure member and is adapted to support a length of wick 10, the arrangement being such that the frame and associated wick can enter the container 1 through the mouth to permit engagement of the closure member over said mouth or, by lifting said closure member away from the container mouth, can be partially withdrawn from the container into a position in which a part of the supported length of said wick is held projecting from the container mouth by frictional contact between said frame and the inner mouth wall. As shown, a bottle 1 having a screwthreaded neck 2 is provided with a cap 3 having an internally screw-threaded skirt 3a. A wire frame bent to form an intermediate transverse portion 4 and two elongated arms 4a, is passed through apertures 6 in a circular metal disc 5 so that the transverse portion 4 lies in a groove 7 (not shown) in the disc 5, which is adapted to be pressed into the cap 3 and to be held there by the skirt 3a. A cork or like disc 8 provides a liquid-tight closure. A wick 10 is folded and sewn or otherwise attached to the frame above inwardly directed bends 4b in the frame arms. The frame arms are arranged with a tendency to spring apart so that when the frame and associated wick is partly withdrawn from the bottle to expose the wick, the arms are frictionally held by the inner wall of the mouth of the container so that the wick stays in the exposed position. When not in use, the frame is pushed into the bottle and the cap 3 screwed tight. The cap is free to rotate independently of the frame and wick.

Title: Improvements in or relating to record card controlled machines
Inventor: HOLDSWORTH ALAN SYDNEY
Filed: 1954-03-17
Abstract: 763,737. Statistical apparatus. POWERSSAMAS ACCOUNTING MACHINES, Ltd. Feb. 25, 1955 [March 17, 1954], No. 7800/54. Class 106 (1). ). Apparatus for coding numerical data sensed from a statistical record card, comprises for a column of a record card, or for each column of a plurality of columns of a card, a column of axially movable sensing pins each to sense a data-indicating position of a card, code bars spring-urged to normally active positions thereof and co-operating one each with a sensing pin for movement lengthwise thereby to an inactive position, notched-edged elements supported for independent lengthwise movement in a plane normal to the direction of movement of the code bars, thereby to initiate impulses according to the coded significance of a code bar. In the apparatus as described, the numerical data on a record card is translated into a four-element code, e.g. the<SP> </SP>1-2-4-7 code, only those parts associated with one column of a card being shown. Located above the sensing pins 2, Fig. 1, are code bars 10 each aligned with a corresponding pin 2 and normally retained in the position shown by a spring 13. Two pairs of edge-slotted members 6 and 7, 8 and 9, Fig. 2, embrace the column of elements 10, each of which has one or more projections 14 which engage adjacent slots in the members 6, 7, 8, 9, to retain them against the pressure of springs 16 so that corresponding switches 23, 21, 24, 22, Fig. 5, are open and pins 29 fixed to the members 6-9 retain a button 27 against the pressure of a spring 28 in position to close a switch 26. When the card 1 is raised for sensing the pins 2 which do not pass through card holes are raised, the corresponding pins 10 are moved against springs 13 and the members 6-9 which are thus freed move to close the corresponding switches 21-24. If no card hole is present in the column sensed all the elements 10 are raised to free the four members 6, 7, 8, 9 and close the switches 21, 22, 23, 24 and the button 27 is moved by the spring 28 to open the switch 26. The members 6-:9 are restored by downward movement of a restoring element 17.

Title: Improvements in or relating to attachments to sewing machines
IPC: D05B3/24
Filed: 1925-03-24
Abstract: 251,740. Preston, H., and Sawers, A. March 24, 1025. Folding-devices.-An attachment for folding the edges of material to be lock-stitched or basted consists of a pair of oppositely reciprocating serrated bars operated by a doubleended rocking-lever actuated by an eccentric and link, one of the serrated bars being so constructed that its operative part can be raised and may also be turned aside out of operative position. The attachment is mounted on a base 1 which is secured to the base-plate of a machine and carries bearings for two shafts 6, 11, the shaft 11 being driven by a belt 22 passing over a pulley 17, a pulley 18 on the main shaft and jockey pulleys 23, 24. The shaft 6 is oscillated by an eccentric on the shaft 11 connected by a rod to a peudent lever 7. The work-folding bars 36, 87 are connected respectively at 47, 49 to a double lever 35 mounted on the shaft 6 and reciprocated therebv. In an alternative construction the shaft 6 is oscillated by a cam on the lower shaft of the machine engaging a lever on the shaft 6. The upper bar 36 is connected by a boss 42 and pivot to a link 46 pivoted to the lever 35. The boss carries a bifurcated extension 43 forming a guide for a lever 56. The bar 36 is retained in working position by a flat spring 50 secured at 51 to a bracket 52 of which a vertical bifurcated portion 53 is connected to the base. The lever 56 is mounted loosely on the spindle 11 and carries a runner which engages a cam-path 62 on a sliding bar 63 fitted with an edge-guide 64. A cam-piece 91 is secured to the lever 56 and engages the underside of the link 46. An operating lever 69, pivoted on the base-plate, can be moved manually between limits set by a spring stop-pin 73 which engages recesses 71, 72. A pin 82 is fixed transversely in the lever 69, the lower part engaging a transverse slot in the sliding bar 63 and the upper part engaging an L-shaped slut 84 formed in a lateral extension 83 on the bar 36. On movement of the lever 69 from the position shown in Fig. 1 towards the recess 72 the slide 63 is moved which causes the cam 62 to move the fever 56, freeing it from the bifurcated member 43, and the cam 91 to lift the link 46 and thereby to separate the arms 36, 37. Further movement causes the swinging of the arm 36 about its pivot. In a modification the actuation of the shaft 6 is effected by a linkage connected with the needle bar. In a further modification the bar 36 is formed in one piece and the cam member 83 is therefore omitted and the construction otherwise somewhat modified.

[Class 40 (v)] [Also in Group XXXVI] An instrument is supplied at a voltage proportional to that of a high-tension supply or with a current proportional to that in a power circuit without serious errors due to regulation or phase shift and without the need for specially designed instrument transformers. For measuring the voltage between a high-tension A.C. line 1 and earth, or for supplying any instrument accurately in accordance with this voltage, a proportional lower voltage is tapped off an electrode of a condenser-type bushing serving as a capacity type voltage divider 2. This voltage is applied through a transformer 3 to a power amplifier with inverse feed-back, which in turn supplies a voltmeter or voltage coil. The power amplifier consists of a pair of valves 4, a grid transformer 5 and an output transformer 6 supplying the instrument terminals 7. The valves 4 are connected in push-pull to the transformer 6. The feed-back voltage is obtained from a potential divider network 8 across the output terminals, a tapped portion of this network being connected in series with the primary winding of the transformer 5. The effective gain of the amplifier may be varied by movement of the slider 8a.
