Title: Improvements relating to water softening plant
IPC: C02F1/42
Filed: 1931-10-26
Abstract: 384,045. Control of motors. UNITED WATER. SOFTENERS, Ltd., PEMBERTON, R. T., LAWRENCE, H. S., and WALTON, J. I. AUSTEN-, Aldwych House, Aldwych, London. Oct. 26, 1931, No. 29681. [Class 38 (iii).] Travelling to predetermined limits.-The valve or valves for changing over from softening to regeneration and vice versa in a base-exchange water-softening apparatus are operated by a reversible electric motor having switches which ensure that the motor is stopped when the valves have been changed over and that, having run in one direction, it must always run in the other direction when next started. The valves 4 .. 7 are operated by linkage from a block 23, Fig. 1, which moves up and down on a screw 22 rotated by gearing 21 from an electric motor 20. The motor circuits comprise two mercury switches 35, 36, Fig. 3, on a spindle 34, turned by a weighted arm under the influence of an electromagnet 39 and two others 31, 32 on a spindle 30 which is rocked by tappet mechanism connected to the block 23. When regeneration becomes necessary the circuit of the electromagnet 39 is closed, either manually by a pushbutton 41 or by a switch 40, operated by means of a clock or of a meter,' which measures the flow, or of apparatus which tests the water which has passed through the softening chamber. The electromagnet causes the spindle 34 to bring the switches 35, 36 into the position shown in Fig. 3 and thus close the circuits of the motor so that it is driven to move the valves from the position for softening treatment to that for regeneration. In the Figure, A, B indicate the terminals for the field circuit of the motor, C, D those for the armature. Leads to the electric main are shown at 42, 43. As the valves approach the regeneration position, the spindle 30 is rocked by the tappet mechanism and the motor is stopped. The button 41 or switch 40 is subject to a time delay and opens again when a definite period for regeneration has elapsed ; the weighted arm then returns the spindle 34 to its former position, and the motor is started in the reverse direction to move the valves back into the softening position: As they reach this, the spindle 30 is rocked and the motor again stopped. An additional switch 33 on the spindle 30 may control the circuit of a lamp 46, which indicates when regeneration is taking place.

Title: Improvements in and relating to sprinkling apparatus for discrete materials
Inventor: PALMER AUSTIN RICHARD
IPC: A21C9/04
Filed: 1962-08-08
Abstract: 979,839. Apparatus for sprinkling sugar &c. on to cake dough &c. BAKER PERKINS Ltd. Aug. 8, 1963 [Aug. 8, 1962], No. 30424/62. Heading A2A. In making sugar-topped cakes, portions of dough batter are deposited in tins 1a, 1b, 1c and 1d, Figs. 1 and 2, strapped together to form a group or rank and conveyed, on a travelling conveyer comprising two belts 2 and 3, to apparatus for sprinkling demerara sugar on to the portions, and then to a baking oven. The sprinkling apparatus comprises a hopper 4 containing the sugar and having shoots 5a, 5b, 5c and 5d terminating in cylindrical outlets 6a, 6b, 6c, 6d surrounded by cylindrical casings 7a, 7b, 7c, 7d located above the paths or files along which individual tins travel. Between the casings and the tins, a sieve 8, mounted in a frame 8a, extends across the conveyer. The frame 8a is mounted between upper slide bars 11 and 12, secured to side frames 10, and lower slide bars 11a and 12a movable vertically in slots 9 in the side frames and connected to the upper slide bars by springs 13. The slide bars have nylon bearing surfaces 29. The sieve frame 8a is connected by a rod 14 to reciprocating or vibrating mechanism driven by an electric motor (not shown). Stops 15 and 16, for holding a group or rank of tins in the sprinkling position, are connected, e.g. through a connecting bar 17, to a solenoid 18, energization of which causes the stops to be moved upwards to halt the group or rank of tins, which, on arriving at the sprinkling position, depress the actuating arm 20 of a switch 19 and start the electric motor and reciprocation or vibration of the sieve frame 8a so that sugar is sprinkled on to the portions of dough batter. The electric motor may run for a desired sprinkling period according to a pre-set timing device controlling the motor. Alternatively, sprinkling may continue until the stops are lowered and the group or rank of tins moves from the sprinkling position and releases the switch 19. The electric motor may be provided with an electromagnetically operated brake, which stops it when the supply of current is switched off. Another approaching group or rank of tins 23 depresses the operating arm 22 of another switch 21 and causes the solenoid 18 to lower the stops 15 and 16 and the tins containing the springled dough batter to be conveyed to the baking oven. The group or rank of tins 23 then moves into the sprinkling position and the sprinkling operations are repeated. Instead of being actuated through the switch 21, the stops may be actuated by lever mechanism, e.g. comprising an operating arm 25, Fig. 3, of a pivoted lever co-operating with a second pivoted lever, to which the stops 27 are secured, or an operating arm 26, Fig. 4, connected to a single pivoted lever, to which guided stops 28 are pivoted. In using sprinkling apparatus according to the invention, sprinkling of sugar on to the inner surfaces of the tins is avoided and removal of the baked cakes from the tins is facilitated.

Abstract: 1,033,488. Photographic plate holders. MEOPTA NARODNI PODNIK. Aug 4, 1964 [July 22, 1963], No. 30656/64. Heading G2A. A magazine holding flat photographic material 120 (Fig. 4, not shown) on a carrier 121 and having a slide closure 3 is equipped with a mechanism for signalling the insertion of the material and its exposure, the mechanism consisting of a pressure lever 5, a swinging lever 4 and a movable member 8 each provided with a signalling flag 51, 41, 81 respectively, at least one of which is positioned below a window 13 provided in the upper portion of the magazine. When there is no material inside the magazine, the black flag 41 is below the window 13, a spring 12 carried by a pin 6, on which the levers 4, 5 are carried, pressing a pin 7 of the lever 5 into contact with the edge 31 of the slide 3, thus positioning the pressure lever 5, and a further spring 9 positioning the member 8 and the lever 4 as shown. When material 120 is inserted (Fig. 3, not shown), its upper edge 102 rotates arm 42 of the lever 4, thus moving the flag 41 out of the window 13, leaving green flag 81 below the window. Immediately before exposure slide 3 is pushed out (Fig. 4), thus allowing the pin 7 to fit into a slot 33. This causes the lever 5 to swing out and push the member 8 sideways and the flag 81 out of the window 13. After exposure the slide 3 is returned to its initial position and lever 5 takes up its original position also. Member 8 and lever 4 are prevented from returning to their original positions by projection 11 and spring 9, thus allowing the red flag 51 to show in the window 13. As the material 120 is extracted from the carrier projection 11 is pushed out and the members 8, 4 return to their original positions under action of the spring 9, flag 41 being set below the window 13.
