Patent GB-515178-A (GB)
Title: Improvements in and relating to thermal switches for electric cookers
IPC: H01H73/28
Filed: 1938-05-26
Abstract: 515,178. Thermal switches. TURNER, C. A., and DIAMOND H SWITCHES, Ltd. May 26, 1938, Nos. 15781 and 17955. [Class 38 (v)] Thermostatic switches for hot-plates can be set by hand to five different degrees of heat. A shaft 2 passing through a casing 1 carries four cams 4-7 against which press spring strips 'carrying contacts 8-11 held by the cams away from corresponding fixed contacts 12-15 until rotation of the shaft allows projections on the spring strips to enter cut away portions on the cams. Three different positions of the shaft 2 cause the pins of contacts 8, 12; 10, 14; 11, 15, to close in different ways to connect two heating elements to the supply to provide high, medium and low heats. To provide a simmering position with a continuous range of adjustment, contacts 9, 13 are closed and a cam 22 on shaft 2 moves down a bridge 18 which is carried on a spring. 23 and itself carries two contacts 19, 20 into engagement with a contact bridge 21 carried at the end of a lever 24 pivoted at 25. Springs 30 are stretched between the end 31 of lever 24 and an end of a bimetallic strip 28 which is rigidly fixed at its other end 29. Bridging of contacts 19, 20 connects the two heating resistances across the supply and in series with them a coil 33 which heats the bimetallic strip 28 until this bends down sufficiently for lever 24 to move down and break the circuit with a snap action. Cooling now allows the bimetallic strip to bend and reclose the circuit when the cycle is repeated. The proportion of time during which the heaters are energised is varied by the setting of the cam 22 which moves the bridge 18 and hence lever 24 relatively to the dead centre position. Compensation for ambient temperature may be obtained by arranging that the support 27 is of bimetallic material and carries down the pivotal point of lever 24 upon a rise in temperature. An index cam 3 with depressions in which balls engage locates the spindle in the three definite control positions. Instead of a separate heater 33, current may pass through the bimetallic strip 28 and directly heat it. The thermostatic control device may be employed either in a switch with more than three heat positions, or by itself. The resistance 33 may be connected to the supply directly, not in series with the heating resistance, and controlled by a variable resistance operated by the switch handle. The Provisional Specification indicates the use of fluid-expansion thermostatic switches. Specification 460,748 is referred to.

The circuit described comprises a magnetic core matrix store effective to add, in parallel mode during an addition operation requiring a plurality of cycles, two multi-digit binary numbers stored in two of the matrix rows. Associated with each column of the matrix is a logical circuit as shown in Fig. 3 for the ith column, lines li, 2i being read and write lines for the column, lines 3 i-1 i , 4 1-i ,  i  being supplied with carry and carry complement signals from the next lower order, and lines 3 i,i+1 , 4 i ,  i+1  providing carry signals for the next higher order. Flip-flops U 1 , V i  are provided for temporary storage and the operation of the circuit is controlled by control pulses C 1 -C 4  applied to gates G 1i -G 4i . An addition operation is completed in 11 cycles, Fig. 5, each cycle comprising a read phase in which the contents of a selected row can be read out to the flip-flops U i  or V i  and a write phase in which the outputs of the gates O i  can be written back into the same or another selected row. The bracketed symbols in the RW column, Fig. 5, indicate, according as the digits thereof are 1 or 0 that the wiring of the associated row is such that a true or complement value respectively is read or written. In operation, the numbets x, y to be added are entered in rows 1 and 2 of the matrix and during the first four cycles 1-4, auxiliary functions p i =x i y i , and q i =xiyi are formed and entered in rows 4 and 5, these functions being entered in flip-flops U i , V i  in cycles 5, 6. During cycles 7 and 8 the carry signals are formed by applying control signal C 4  to gates G 4i , Fig. 3, thereby allowing carry propagation through the various logical circuits, signals c i  and c i  being stored in rows 7 and 8 of the matrix. During the remaining cycles of the operation, the sum digits s i  are formed and stored in row 3 of the matrix. The circuit may be modified to perform subtraction and to operate on excess-3 coded decimal numbers. The parity bit of a binary number may be calculated by storing the bits x i  of the number in the flip-flops U i  and V i .

Title: Improvements in the manufacture of mixed esters of poly-hydroxy compounds
IPC: C07C69/00
Filed: 1945-06-25
Abstract: Mixed aliphatic-aromatic esters of polyhydric alcohols are prepared by heating the complete ester of the alcohol and the more volatile acid with the less volatile acid whereby part of the more volatile acid is replaced, and removing from the reaction zone the liberated acid.  The polyhydric alcohols may contain 3-6 hydroxy groups, glycerol, erythritol, pentaerythritol, mannitol and sorbitol being specified.  The aliphatic acid component may be a saturated fatty acid such as acetic, propionic or n-butyric, while the aromatic acid is preferably a mononuclear acid such as benzoic, alkyl benzoic, halogen-substituted benzoic or alkyl benzoic, e.g. a chlorbenzoic, or phenyl-acetic.  The initial ester and the less volatile acid may be heated in proportions corresponding to the ester required but, preferably, the ester is used in excess, for example 1.5-2.5 times the theoretical.  Thus, for glycerol diacetate benzoate, 1.5-2.5 mols. of triacetin and 1 mol. of benzoic acid are used.  This reaction begins at about 220 DEG  C. and is finally raised to about 280-300 DEG  C.  An acid catalyst may be present, and a high boiling liquid which may be a solvent for the reactants or form an azeotrope with the liberated acid. Preferably, a still without a column is used, lined with glass or enamel.  The initial ester may be made by refluxing the alcohol or an epoxide thereof with the acid or anhydride and, optionally, sulphuric acid or copper sulphate.  The mixed esters are plasticisers for cellulose esters and ethers such as the acetate, propionate, acetate-stearate, acetate-butyrate and soluble ethyl celluloses.  In an example, triacetin is prepared by adding glycerol to an excess of acetic anhydride boiling under reflux, and distilling under reduced pressure.  The residue of triacetin is heated with half the equivalent of benzoic acid to a final temperature of 280 DEG  C. and glycerol diacetate benzoate recovered by fractionation.  It may be washed and dried in air at about 60 DEG  C. under reduced pressure.

Filed: 1922-06-07
Abstract: 202,100. Burnett, A. J. H., and Hutchinson, G. W. Grice- June 7, 1922. Money-delivering apparatus. - In a notechanging apparatus of the kind in which drawers mounted' in a case deliver change from the drawer to an open till when a note has been inserted in the drawer and, the drawer closed, provision being made for automatic locking, a series of drawers 11 are arranged in a case 2 which can be locked in a cabinet 3. Each drawer has a partition 12, behind which is placed the change to be delivered. On closing the drawer the change falls to a drawer till 23, from which it can be removed. The locking-means comprise a gravity catch 13 pivoted to the side of each drawer. When the drawer is closed, the catch 13 engages a notch 14 to prevent re-opening until the case is inverted. The movement of the drawer is limited by a stop 16 which engages a groove 15 in the case. To ensure that the drawers shall be only pushed home in turn, a gravity catch 17, pivoted in the groove 15 of each drawer except the top one, has a notched end which normally engages the stop 16 on the drawer below to prevent closing. When the upper drawer is pushed home, the bottom of the stop 16 engages the upper end of the catch 17, and rotates it out of engagement so that the drawer can be pushed home in turn. In a modification, Fig. 5, a pin 18 and stop 19 engage respectively the upper and lower edges of a catch 20. When the drawer is closed, the pin 18 engages in a slot 21, thus holding the drawer closed.
