Title: Improvements relating to apparatus for indicating and/or controlling a dimension of articles moving in the direction of such dimension
Inventor: KELSALL RICHARD HOPE
IPC: G01B11/04
Filed: 1953-05-27
Abstract: 723,822. Measuring length. METROPOLITAN VICKERS ELECTRICAL CO., Ltd. May 27, 1953 [July 24, 1952], No. 18799/52. Class 40 (1) [Also in Group XL (b) ]. An apparatus for measuring the deviation from a standard length of articles moving in the direction of their length, comprises two detector devices spaced apart in the line of motion, giving impulses in response respectively to the passage of the leading and trailing edges of an article, and means for integrating a current proportional to speed over the time interval between the impulses to give a measure of length. The deviation measured may be indicated and/or may control the length of the articles. In the first embodiment described (Fig. 1) for red-hot steel billets, two photoelectric cells PC1 and 2 equipped with collimators are at a distance apart equal to the standard length and feed pulse generators P.GENS 1 and 2 which give simultaneous short rectangular pulses b, b1 of opposite sign which sum to zero if the billet is standard. If it is not the pulses are no longer simultaneous and the sum consists of two consecutive pulses of opposite sign which are integrated in INT 1 to give a rectangular pulse C of duration equal to the pulse interval and of sign dependent on the order of occurrence of pulses b, b1. This pulse actuates an electronic switch ES which according to its sign switches on one of a pair of integrator circuits in INT 2 for the duration thereof, the integrator circuits being supplied with the output of a tachometer generator TG connected to the billet conveyer to give an integrated voltage of sign dependent-on whether the deviation is positive or negative proportional to the deviation in length. The circuit RS, tripped by the leading edge of wave C effects transitron resetting of the integrator circuit after a fixed time interval. In a modification (Fig. 2) the amplified outputs of the photo-electric cells trigger circuits, which may be of the flip-flop type having a stable and an unstable state or having two stable states, producing outputs d, d1 which have steps of opposite sign differing in time so that the summated output is again a rectangular pulse C of duration equal to this time difference, this pulse directly operating the electronic switch ES. If the circuits are of the flip-flop type the resetting time must exceed the maximum period between pulses, whilst if they have two stable states the integrator resetting device is arranged to give a resetting pulse to both a fixed time after the occurrence of the first step. The output voltage of the device may be used for resetting the shearing machine to reduce the deviation in length.

Title: Process and apparatus for impregnating wooden posts to protect them against rot particularly the posts of overhead electric supply lines
IPC: H01H85/046
Filed: 1954-06-29
Abstract: 786,741. Rot-proofing standing wooden posts. SOMMER, J. June 29, 1954 [July 6, 1953; Oct. 31, 1953], No. 19066/54. Class 140. Standing wooden posts are preserved from rotting by applying wood-impregnating media to the free end of the post by means of a device having a handle for raising to the top of the post a wood-impregnating medium held by the device. As shown, a long steel tubing handle 2 carries detachably, by means of a tapered pin 41, at its upper crooked end 3 a ball joint 40 which is secured to a plate 16. Guide-rods 17, 18 are pivotally connected at 19, 20 to a pair of semicircular flaps 7, 8 hinged together at 9, and guide-rods 12, 13 are pivotally connected to sleeves 10, 11 on the hinge pintle. The guide-rods pass through the plate 16, rods 17, 18 having retaining nuts 23, 24, and the parts are urged to the position shown by springs 14, 15, 21, 22 surrounding the rods. In use, a sheet of creped filter paper is stuck at intervals to the under-faces 43 of the flaps 7, 8 and the rot-preventing medium 6 in paste form is applied to this paper sheet to which it adheres. Instead of a paste the rot-proofing substance may be crystals in a water-permeable envelope or a block stuck to the paper and coated with adhesive on its post-contacting face. When the rot-proofing substance is applied to the top of the post it adheres more strongly to the post than the paper does to the flaps so that the rotproofing substance covered by a paper sheet remains on top of the post. If the post has a gabled top, the applicator is applied to it with the hinge along the ridge when the flaps 7, 8 move against the slant faces on compressing the springs 14, 15. In a modification for use with posts having conical ends, the flaps 7, 8 are replaced by four segmental conical members each provided with springs urging them together and they are maintained extended substantially coplanar, for application of the rot-proofing substance to them, by means of a cap which is freely suspended from the frame of the applicator and retains the bent-up apical extensions of the conical members, a pin depending from the cap engaging the apex of the post to free them from it. In an alternative arrangement, the applicator comprises a holder detachable from the handle for retaining a leather bag containing sponge rubber discs, two of which may be apertured to permit deformation to conform to the end of the post, a filter paper carrying the rotproofing substance being stuck at intervals to the bag.

[Class 82(ii)] The automatic regulation of liquid in washing chutes by supplying additional liquid the volume of which is controlled by a valve operated by an automatically operated lever which displaces a slide regulating the opening of an evacuator, is obtained by operating the valve by the lever only when the lever is travelling on a predetermined portion of its path. As shown a lever 3 mounted on a chute 2 is pivoted at 31, the lower end operating a slide 4 controlling the opening of an evacuator 5 and the upper end having a roller 34 the spindle of which may be fitted in any one of a number of holes 33. The roller 34 operates in a slot in a rod connected to a valve 10, which may be a balanced slide valve or arranged for " all- or-nothing " action, for the supply of additional liquid to the top of the chute. The lever continuously operates the slide 4 but only operates the valve 10 when passing from the part 131 to the part 132. The slide 4 may be arranged as a piston having openings in the rear part of the skirt, Fig 3 (not shown). The valve 10 may be replaced by an electromagnetic valve controlled by the lever 3.
