Title: Improvements in or relating to lift safety devices
IPC: B66B13/18
Filed: 1946-01-07
Abstract: 601,240. Multiple fastenings; bolts. COATES, A. F. Jan. 7, 1946, No. 490. [Class 44] [Also in Group XXX] The drive switch operating member of an electric lift also operates a well or cage doorlocking element and a feeler which is held against movement when the door is open, so that the switch cannot be closed to operate the lift unless the door is closed and locked. As shown (Fig. 5), a bolt 3 is slidable vertically in a housing 11 of the well door lintel to engage a keeper 25 in the top of a swing door 7. The bolt is operated by a horizontal slide bar 18 having a plate 15 with a cam-slot 19 engaging a pin 23 coupled to the bolt, the cam-slot having horizontal end portions to lock the bolt in its extended and retracted positions. The feeler 4 is similarly constructed, and operated by the slide bar 18 simultaneously with the bolt 3. It can only be extended, however, when the door is closed and a slot or keeper 26 in the door registered with it, either the door itself or an extension 27 obstructing movement otherwise. The slide bar 18 has a pin and cam-slot connection 36, 80 with an operating member 78 slidable vertically in a lock box 2 mounted in the lift well, the operating member 78 also having a pin and cam-slot connection 79, 71 with a switch 32 controlling the lift drive. Both cam-slots 79, 80 have vertical end portions to lock the switch 32 and bar 18 in their end positions. In operation, downward movement of the operating member 78 first frees the bar 18, then pulls it to the right and relocks it. This releases the bolt 3 and feeler 4 and projects them into locking engagement with the door and then relocks them, but if the door is open, the feeler 4 is held and movement of the operating member 78 is arrested. The final movement of the operating member closes the lift switch 32. The door 7 shown is one of a pair of swing doors, the rod 18 being extended to operate the bolt and feeler of the other. The bolt 3, moreover, is adapted to depress a spring- retracted push-rod 100 to lock the lower edge of the door to the sill. A Bowden connection, Figs. 15 and 16 (not shown), may, alternatively, operate a lock in the sill from the lock box 2. The operating member 78 in the lock box 2 may be actuated automatically by a motor or electromagnet, but, in the arrangement shown, it is adapted to be engaged and actuated by a bar 46 projected from a controller 1 mounted in the lift cage. A similar arrangement of bolt and feeler may be applied to the cage door and be operated by the controller direct. Where lattice gates are employed, either at the landings or on the cage, the feeler 4 co-operates with the suspension rollers of the gate, projecting behind the innermost when the gate is closed-to. Specifications 601,242 and 601,244, [both in Group XXX], are referred to.

Abstract: 1,273,117. Chess. PERMSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI GOSUDARSTVENNY UNIVERSITET IMENI AM GORKOGO. 6 Jan., 1971, No. 582/ 71. Heading A6H. [Also in Division G4] A device for demonstration of chess play comprises a chessboard with chessmen and a demonstration board with 64 actuating units, wherein each chessman of the chessboard carries an oscillatory circuit tuned to a frequency assigned to the name of the given chessman, and an induction coil is mounted under each square of the chessboard, the induction coil being connected to the output of a pulse oscllator which furnishes exciting pulses to all induction coils in succession, and being connected to the input of a filter unit which controls the actuating units of the demonstration board. For each square of the chessboard in turn, the filter unit applies a voltage to one of 12 leads to identify the chessman on the square (if any), a diode network coding this into voltages present on one, two or three of five leads, a NOR gate producing a voltage on a sixth lead in the absence of a chessman. The six leads are gated to storage thyristors in the actuating unit of the corresponding square of the demonstration board to energise one of three stator windings (spaced at 120‹), and none, one or two of two relays controlling energisation of two rotor windings crossed at 90‹, to give the rotor one of 12 angular positions, if a chessman was present. In the absence of a chessman, a further stator winding is energised alone to give a 13th position to the rotor. Attached to the rotor is a glass disc bearing photo images of 6 black and 6 white chessmen and a blank field, one of these being displayed by optical projection. Alternatively, each actuating unit may have 13 optical projectors each including a slide and a lamp, the 12 outputs of the filter unit (excluding the diode network coder) and a 13th output from a NOR gate energising respective lamps via storage thyristors.

Title: Improvements in latch mechanism
IPC: E05B65/32
Filed: 1925-01-10
Abstract: 240,116. Budd Manufacturing Co., E. G., (Assignees of Ledwinka, J.). Sept. 18, 1924, [Convention date]. Latches, swinging; catches, spring.-In order to make the glass pane above the lower part of a vehicle door of maximum width, the door-securing means comprise a device pivoted to the doorpost and co-operating with engaging and releasing means mounted on each side of the door so as to leave a clear passage between them for the sliding window. In the form shown, the device comprises one or a pair of catches 22 pivoted to swing horizontally at 23 on the metal door-post 10 and having a nose 24 fitting into a recess 15 in the door edge. A tongue 34 limits the outward movement of the catch under the action of its spring 25. One side of the recess 15 is bounded by the door-frame part 37, this part having an angle-plate 31 affixed to contain the guide for the sliding window 18 so that the window extends between the inner and outer latch-operating mechanism. The outer side of the recess 15 is formed by a latch 28 pivoted at 26 to the plate 41 secured to the inside of the door and normally held in operative position by a coiled spring 28<a>, Fig 5. To open the door from the inside, the latch 28 is tilted by the handle 27 to be flush with the door-edge so that there is now no member on the door in the path of the nose 24 of the catch 22. The bevelled faces of the latch 28 and catch 22 allow automatic engagement to take place on slamming the door. The door is opened from the outside by turning the handle 29 to cause a follower 49 to push forward a slider 30 so that its nose 47 engages the catch 22 near its pivot and causes it to be pushed back into the doorpost so that its nose leaves the recess 15, allowing the door to be opened. The slider 30 has a lug 56 co-acting with an adjustable screw stop 55 to limit its forward movement so that the catch 22 cannot be pushed so far into the doorpost that it would preclude the operation of the other catch to release the other door 12. A further lug 61 working in a slot in the fixed lockplate 42 forms an additional stop. The outside operating means 29 may be rendered inoperative bv opening the door and tilting the pivoted lever 57 so that its end comes into the path of a lug 58 on the slider 30, preventing this from being moved forward to retract the catch 22. Studs 60 engaging recesses retain the lever 57 in either of its positions. Specification 243,601 is referred to.

Abstract: 764,113. Syringes. SOC. EREC. SCC. D'ETUDES DE REALISATIONS ET D'EXPLOITATIONS COMMERCIALES. Jan. 11, 1955, No. 828/55. Class 102(2) [Also in Group XXXVI] An apparatus for filling a number of receptacles, e.g. cells 2, comprises a cylindrical liquid reservoir 3 having passageways 4 communicating with the cells 2, and two pistons 5, 9 separated by the liquid 10 and initially located as in Fig. 1. When the top piston 5 is released, it is urged downwardly by a spring 7, thus forcing the liquid and the piston 9 to move downwardly. As the inlets of the passageways 4 are uncovered by the movement of the piston 9 (Fig. 2), the liquid is forced through them to fill the cells 2. The descent of the piston 9 is first arrested by members 11 when the latter abut against the reservoir shoulder 3a. Towards the end of downstroke of the piston 5, the latter depresses a rod 12 so as to withdraw the members 11 thus enabling the piston 9 to descend still lower as in Fig. 4. The cells 2, instead of being located outside the reservoir, can be placed inside a surrounding annular reservoir having two annular pistons.

Title: Improvements in or relating to the preparation of a sugar ester
IPC: C07H13/06
Filed: 1960-01-11
Abstract: Sugar esters are prepared by dissolving or suspending a sugar in an aqueous alkaline medium, slowly adding a carboxylic acid chloride to the solution or suspension with turbulent agitation, maintaining the pH of the mixture between 7 and 11, adding to the crude soap-containing sugar ester thereby formed an aqueous solution of a non-acidic electrolyte salt or finely divided sodium chloride if said crude sugar ester contains sufficient water to enable a brine layer to be formed, permitting the mixture to separate into an ester/soap layer and an electrolyte/sugar layer, removing the latter layer and extracting from the ester-soap layer the sugar ester with an organic solvent therefor which is a non-solvent for the soap, e.g. a ketone, such as acetone, a hydrocarbon, a lower alcohol or a chlorinated hydrocarbon, and recovering substantially pure ester from the solvent, the ester-soap layer preferably being dried before the extraction. The preferred reactants are sucrose and C2-24 saturated and unsaturated fatty acid chlorides especially those of stearic and palmitic acids.  The sugar and acid chloride may be used in molar ratios from 3 : 1 to 1 : 3.  The desired pH may be maintained by addition of alkali.  Esterification is normally effected at below 65 DEG C.  Examples are given.  The esters may be used in fatty food stuffs as anti-spattering agents.  Specificatio 858,440 is referred to.
