Title: Improvements in or relating to handle-operated latch or lock mechanism for hatches, doors and the like
IPC: E05B5/02
Filed: 1946-02-23
Abstract: 599,440. Sliding bolts. BRITTAIN B., and SQUIRE, H..J. G. Feb. 33. 1946, No. 5640/45. [Class 44] In a handle-operated bolting mechanism for aircraft doors or hatches having the rotatable bolt-operating spindle axially slidable to allow the outer operating handle to be pressed inwards to lie flush with the door or hatch surface with the spindle held in such inward position against the action of a projection spring by a releasable catch engaging a notch in the spindle, the spindle is provided with a second notch angularly staggered and engaged by the catch when the spindle is in its projected position and turned to the unlocking position of the bolts. Thus, the handle can only be depressed when it has been turned back to the locking position of the bolts. The spindle 16 is slidable in, and rotates by a pin 20, a sleeve 19 rotatable in the latch casing 10 and carrying a spider 26 having four connections 27 to operate four separate locking bolts. The spindle 16, which is hollow, has copper-welded thereto a handle 14 which on forcing the spindle axially inwards into the sleeve 19 against the action of a spring 28, is received in a recess 13 formed in an extension 12 of the latch casing so that the whole lies flush with the door or hatch surface ; a spring-urged catch bar 31 enters a notch 32 in the spindle to retain it in the inner position. Release of the catch 31 is effected by a pushbutton 15 which moves a plate 35 sliding through a slot 36 in the catch bar 31 and retracting the catch bar 31. by means of a cam edge 37. The catch bar 31 is also able to enter an angularly staggered notch 38 in the spindle when the latter is projected and turned to the opening position of the locking bolts so that only when the spindle has been turned back to the locking position of the bolts is the catch bar 31 forced back to allow the spindle to be pressed inwards. In the inner position, rotation of the spindle is prevented by the walls of the handle-receiving recess 13 engaging the handle 14. The catch 31 may be remotely controlled, e.g. electrically, and the spindle may be provided with key-lock means. The handle 14 may be of hollow form made by copperwelding two sheet steel pressings together.

Title: Electrochemical liquid treatment device
IPC: C02F1/469
Filed: 1962-02-15
Abstract: <PICT:0991468/C6-C7/1> <PICT:0991468/C6-C7/2> <PICT:0991468/C6-C7/3> <PICT:0991468/C6-C7/4> In an electrochemical liquid treatment device, such as an electrodialysis or ion exchange device, the electrodes are electrically connected such that deposits which would impair their efficiency do not build up on them.  A first electrode is of one polarity whereas second and third electrodes in close proximity with one another can alternately be connected so as to be of opposite polarity to the first electrode. Fig. 1 shows an electrodialysis device comprising a central anode 19 and electrodes 12, 13 (shown in detail in Fig. 2) which can be alternately connected as cathode by means of a reversing switch 33 and timer control 35.  The electrode of 12 and 13 not connected as cathode serves as an anode but takes a reduced current through a resistance 34.  Cation and anion selectively permeable membranes 22, 23 extend in a spiral path between the anode and cathodes from a tube 20 perforated at 25 to a tube 24 perforated at 26.  Liquid to be treated is supplied to the tube 20, flows through the space between the membranes, is electrodialytically diluted and discharges through tube 24.  Flushing liquid is supplied to and removed through apertures 27, 28.  Fig. 4 shows a liquid treatment apparatus containing ion exchange material 56 which is regenerated electrolytically. A central carbon anode 42 and Pt electrodes 12, 13 are electrically connected similarly to the electrodes shown in Fig. 1.  A permeable ceramic diaphragm 50 retains the ion exchange material.  Liquid to be treated is supplied intermittently at 59 and removed at 541 and flushing liquid is supplied and removed continuously at 55 and 54. Electrolysing current is supplied continuously.  Fig. 5 shows electrodialysis apparatus with two switches 33 actuated by a single timer control 35.  In one switch position electrodes 66 are anodes, 67 are cathodes, 65 are slightly cathodic and 68 are slightly anodic. In the other switch position, electrodes 65 are anodes, 68 are cathodes, 66 are slightly cathodic and 67 are slightly anodic.  62 and 63 are cation and anion permselective membranes.  Anion permselective membranes 63P are porous to some extent and let the liquid pass through them to the electrode compartments to wash the electrodes.  Further embodiments wherein the electrodes are washed and electrode products are prevented from migrating through the membranes of the stack are illustrated in Figs. 8 and 9 (not shown).  In alternative embodiments, Figs. 3 and 7 (not shown), electrodes used in apparatus similar to that shown in Figs. 1 and 5 are in the form of helices and spirals. In further alternative embodiments, one set of the alternately used electrodes may pass no current while the other set operates or more than two sets of electrodes may be used in sequence controlled by rotary multipole switches.

Abstract: 1,203,533. Bait retriever and reel. T. M. SPLAWINSKI. 4 Feb., 1969, No. 5919/69. Heading A1A. The bait retriever consists of two concentric loop members 10 and 11 rotatably joined along the minor axis direction by spindle 16. A heavy retrieving line 21 is attached to loop 11 at 17, and the snagged fishing line is threaded through the loop 11 by passage through the parallel slit 23<SP>1</SP> and the transverse slits 26 and 27 cut into the end of loop 10. The retriever is allowed to run down the snagged line until the bait, or hook is encountered, when the retrieving line 21 is tensioned and causes end 15 of loop 11 to trap the bait, or hook against end 19 of loop 10. Further tension either causes freeing of the hook or breakage of the tackle at some point below the retriever. In a fish bait retriever and reel assembly in which the bait retriever is of the looped type, the reel consists of a casing 36 with a hollow spindle 39 to mount the retrieving line reel 41, and on the other side has prongs to engage in the users belt or clothing. The retriever, when not in use, is clamped to the reel by engaging spindle 16 in slots 49 in the end of the spindle 39.
