Title: Improvements in or relating to counting devices
IPC: G06M1/10
Filed: 1927-05-27
Abstract: 296,718. Igranic Electric Co., Ltd., and Mackley, A. H. May 27, 1927. Divided application. Transmitting actuation to counters.-Simultaneously occurring or other movements set corresponding relays which by means of a rotary switch are put seriatim in circuit with a grand counter and are then restored to normal in readiness :for the next actuation. In the arrangement shown in Fig. 1 the relay consists of two solenoids OW, CW with respective armature contacts OC, CC. The winding OW is in circuit with the switch 27 closed by the movement to be counted and when energized is temporarily attracted to place the armature contact CC within range of the winding CW. The relay is now in set condition with the contacts OC, CC closed. When therefore the rotary switch arm 29a reaches the contact 29<b> allotted to this relay the circuit through the counter 30 is closed. On reaching the next contact stud 29<c> the arm short circuits the winding CW to release contact CC so that the relay resumes its original state. As in this arrangement it is possible for a count to take place at 27 during the passage of the switch arm from contact 29<b> to contact 29<c> and thus be missed, three other arrangements involving only one kind of contact 29b are devised. In the arrangement shown in Fig. 2 the operation of switch 27 energizes winding OW to move contact OC to open position and shift contact CC to closed position where it is then held by winding ecw energized through the contact CC and contact cf. When the distributing switch 29a reaches the appropriate contact 29<b> therefore the circuit through the counter 30 is completed and as a reverse winding dcw is energized at the same time the contact arm CC falls away to leave the relay in statu quo. In two further arrangements a larger number of solenoids and multiple armature contacts are utilized. Reference has been directed by the Comptroller to Specification 228,600.

Title: Improvements in and relating to the manufacture of glazed tiles
IPC: C04B41/86
Filed: 1947-07-03
Abstract: Tiles made by pressing clay dust in dies or moulds are produced with a rough or pitted surface by placing between the tile and the die a loose cushion or liner having the required surface characteristics, so that, in glazing, the first coat of glaze will sink into the crevices of the surface.  The loose liner may be an abrasive fabric such as emery cloth or a sheet of metal or moulded rubber, and the degree of roughness of its surface may vary to suit the glaze.  After the tile is thus pressed it is fired, being preferably tilted at a suitable angle for firing, and the first coat of glaze is applied. Surplus glaze is removed, and further glazing and remaining treatment proceed in known manner, the different glazes being mixed if required to produce various colour effects.

Title: Improvements in electrical circuit arrangements of electro-magnetic devices for indicating the magnitude of a deflection
IPC: G01G7/02
Filed: 1948-06-30
Abstract: 701,091. Measuring bridges. BLACK & DECKER MANUFACTURING CO. June 30, 1948 [April 5, 1948], No. 17548/48. Class 37 [Also in Group XXXVIII] In a bridge circuit for indicating the deflections of a balance or scale of the kind described in Specification 698,793, [Group XXXVIII], an armature is displaced by a moving member of the scale between the poles of two magnetically cored coils to differentially vary their inductances. The coils 1, 2 are connected in series with fixed resistances 7, 8 as adjacent arms of an A.C. fed bridge whose remaining arms comprise the potentiometer 11 symmetrically in series with condenser 13 and condenser 14 each of which is in series with a pair of variable resistances correspondingly ganged in opposition and in tandem, respectively for zero and calibration adjustment, and the unbalance voltage between the junction of the coils and the potentiometer slider is applied through switch 24, 25 to an indicating circuit. The latter comprises two bridge rectifiers whose D.C. outputs are connected in series through the fixed and variable resistances 31 and 32 with a galvanometer 30 connected between the junctions of the resistances and the rectifiers. The A.C. terminals of the rectifiers, respectively in series with fixed resistances 33, 34 are connected across the secondary of a transformer 20 whose primary is energized from the A.C. supply through a current reducing resistance. Initially, the switch 24, 25 is open and the resistance 32 is adjusted so that the galvanometer connects equipotential points and reads 'zero. With no load on the scale and the armature symmetrical between the coil cores, the switch is closed and the resistances 14, 15 are varied until the bridge is balanced and the galvanometer reads zero. With a load on the scale the bridge unbalance voltage due to the armature displacement adds to the A.C. voltage on one rectifier and subtracts from that on the other, so that the galvanometer is deflected. This deflection is zeroized by adjusting the potentiometer slider, and the load is indicated thereby in a calibrated dial linearized by the pre-set resistances 37, 38 shunting the potentiometer. The condensers 13, 14 equalize the phases of the two branches of the bridge to eliminate at balance any residual voltage in quadrature with the excitation voltage.

Abstract: 1,017,799. Freezing apparatus. A. ESPER. SEN, A/S. April 29, 1964 [May 3, 1963], No. 17827/64. Heading F4H In freezing apparatus of the type comprising a plurality of freezing jackets connected at their upper ends to the compressor suction and discharge sides through shut-off valves and at their lower ends to a refrigerant reservoir, a closure member for the bottom of the space enclosed by the jacket is provided and is adapted to engage a portion of the inner wall of the jacket which is level with or above the point at which the connection is made to the refrigerant reservoir to ensure that the closure member is freed from frost when hot refrigerant is supplied to the jacket. As shown in Fig. 1 the top of a freezing jacket 4 is selectively connectible through a pressure-responsive valve 5 with either a refrigerant receiver 3 or a line 6 which communicates with the compressor discharge line 8 and includes a valve 7. The receiver normally receives liquid refrigerant from a condenser 10 and supplies it through a line 19 and valve 20 to the bottom of jacket 4, refrigerant vapour being returned to the receiver through valve 5 and thence to the compressor through line 2. The bottom of the jacket 4 is provided with a closure member 21 which as shown in Fig. 2 comprises a frusto-conical plug 24. The latter contacts the inner wall 4b of the jacket immediately above a lower downwardly divergent portion 4c of the wall, the pipe 19 being connected to the jacket at a point below the top of portion 4c. The plug 24 is mounted on a plate 26 hinged at 27 to a bracket 28, the free end 33 of the plate being engaged by an arm 32 of a pivoted lever the other arm of which carries a knob 35 and is connected to a bracket 30 by a spring 37. When hot refrigerant is supplied to the jacket 4 to release the frozen product, the knob 35 is depressed manually to cause arm 32 to move clear of plate 26 and rotate a bell-crank 61, 62 one arm of which bears against the upper surface of plate 26 to open the closure member to a limited extent. The knob is then released and the lever is rotated by,spring 37 in an anti-clockwise direction so that arm 32 causes the closure member to open further. Complete opening of the closure member is effected by the frozen product which is forced out of the jacket by a pneumatically operated piston 18 (Fig. 1), a pneumatic device 22, 23 being provided for returning member 21 to its closed position. Valve 20 in line 19 is closed by the passage therethrough of refrigerant vapour during the thawing period but has a by-pass passage therein to permit the passage of condensate from the jacket 4.
