Patent GB-776536-A (GB)
Title: Apparatus for measuring high degrees of dryness
Inventor: JOHNSON KENNETH IAN
IPC: G01N7/16
Filed: 1954-04-08
Abstract: <PICT:0776536/III/1> <PICT:0776536/III/2> In apparatus for determining the completeness of drying of articles wherein such apparatus comprises the application of suction to the articles 1, which may for example be insulators for electric capicitors or paper insulated electric cables, by a pump P, the suction pipe has branches 9 and 10 at points A and B between which is located a refrigeration vessel 5 wherein water or other vapours in the suction stream are condensed by a suitable refrierant such as solid carbon dioxide.  The condensation of the vapour causes a difference in the vacuum existing at the points A and B, which is measured by vacuum gauges 11 and 12 of the Pirani type so that an instrument 23 in a suitable circuit will provide a reading which will be related to the difference of pressure at A and B and therefore to the dryness of the stream of air.  To allow for a possible leakage of comparatively dry air into the apparatus which will produce a pressure gradient throughout the apparatus which is large compared to that which would otherwise exist, apparatus such as that shown in Fig. 2 may be used, wherein operation of the drying process would be continued until the pressure drop across two points A1 - A2 in the pipe on one side of the refrigeration chamber 6 was substantially equal to that across the points B1 - B2 on the other side.  In another arrangement only three Pirani gauges are used, the intermediate one being responsive to pressure in the refrigerant chamber.

Title: Improved construction of lock
IPC: E05B37/16
Filed: 1933-04-07
Abstract: 417,525. Permutation locks. JOHNSON, C. W., 16, Sibthorp Street, Lincoln. April 7, 1933, No. 10448. [Class 44.] A permutation lock is applied to a door, such as the door of a motor road vehicle, to prevent the external handle from operating the latch until the lock mechanism is correctly set. The casing 10 has a wall 10<a> with a number of holes in which rest cylindrical studs 21 with conical heads 23 arranged above grooves 22. The heads 23 project through holes 15<c> in plates 15 which have reduced ends 15a, 15b resting in slots in the casing walls 13, 13<a>. A comb spring 18 attached to the side of the casing keeps the plates in the position shown in Fig. 8, with the ends 15<a> projecting from the casing. Each plate has a hole for the passage of the conical head 23 of its corresponding stud, but one or more of the holes is out of alignment with the remainder, so that one or more of the studs is locked against movement. The studs are fixed to a plate 20 which carries a hookshaped projection 24 normally engaged by the hook 25 secured to the spindle 26 of the external door handle 27. This engagement locks the handle 27 against movement. To release the handle, certain press buttons 31 are depressed to move the plates with displaced holes, so that each hole is concentric with its corresponding stud. The handle 27 can then be operated, and during the first part of its movement the engagement of the hooks 24, 25 causes the withdrawal of the heads 23 from the plates 15. The continued rotation of the handle operates the latch 33 so that the door can be opened. The handle 27 is returned to its normal position by a spring, and the hook 25 raises the plate 20 and the studs 21 to the locking position. The latch can always be operated by the internal handle 32.

Filed: 1944-06-06
Abstract: 583,918. Heel seat fitting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., CLARKE, T. B., and WILLIAMS, F. W. H. June 6, 1944, No. 10835. Addition to 525,815. [Class 17 (i)] A heel seat fitting machine of the character described in the parent Specification is provided with an ejector for the cut-off portion of the heel end of the sole, the operative stroke of which is adjustable for different sizes of shoes. The rejector 20, which has a T-head 22 and reciprocates above the matrix 24, is pivoted at 56 to the downwardly-extending arm 48 of a bellcrank lever 42 pivoted on a shaft 38. The forwardly-extending arm 60 of this lever is connected to the downwardly-extending arm 62 of a second bell-crank lever 40, also pivoted on the shaft 38, by a spring 68, which acts to urge the lever 40 in a clockwise direction, so that its arm 62 engages a stop 76, and the lever 42 in an anti-clockwise direction, i.e., in a direction to retract the ejector 20, so that its arm 60 engages a stop 80. The lever 40 is constantly urged in a clockwise direction by a spring 70. A pawl 108 pivoted on the arm 62 of the lever 40 is adapted to engage a notch in the arm 60, in order to lock the two levers together, when a roll 118 on the pawl engages the appropriate part of a relatively-fixed cam plate 44 which is mounted on the shaft 38. A latch arm 84 provided with a shoulder 82 is pivoted at 86 to the rear end of the reciprocating tonguing-knife slide 52 and is pressed upwardly by a spring plunger 92. The Figure shows the parts in the idle position. In operation, the slide moves forwardly on its cutting stroke. As it returns, the shoulder 82 engages the arm 62 and rocks it in an anti-clockwise direction. Towards the end of this movement, the pawl 108 engages the notch in the arm 60. When the latch arm 84 is fully retracted, its rear end comes beneath a rod 94 which is linked to the treadle which depresses the bulger associated with the matrix. Release of this treadle causes the rod 94 to descend to trip the latch arm 84, whereupon the levers 40 and 42 move together in a clockwise direction under action of the spring 70, causing the ejector 20 to make its operative stroke, until the cam 44 releases the pawl 108 from the notch permitting the lever 42 to rock in an anti-clockwise direction to withdraw the ejector. The cam is adjustable by way of a bolt engaging a curved slot in the framing, so that the point at which the pawl is disengaged from the notch, and consequently, the length of stroke of the ejector, may be varied. Specifications 430,758 and 462,231 also are referred to in the Provisional Specification.
