Title: Apparatus for regulating automatically the temperature of draught liquids
IPC: F25D31/00
Filed: 1929-12-07
Abstract: 344,083. Thermostats; refrigerators. FISCHER, E., Am Lorenzweg, Magdeburg, Germany. Dec. 7, 1929, No. 37594. [Classes 29 and 64 (ii).] The temperature of tap liqudis is regulated by arranging that portion of the pipe conveying the liquid which is near the tap, as a coil in a tank of liquid the temperature of which is maintained constant by a thermal switch which switches on either an electric heater or the motor of a refrigerating plant. A temperature-regulating chest 1, Fig. 1, is provided with a vessel 2 filled with brine through which passes pipe coils 3 .. 6 containing the tap liquid. The cooling device consists of a cylinder 7 containing sulphurous acid, a compresser, and a motor 13, Fig. 3, for driving the compresser. The heating device consists of an electric heater 10, and a thermostat 14 is provided. The indicator of the thermostat, Fig. 4, is provided with two contacts a, b over which moves a pointer 17 provided with a small roller. The insulating member 15 between the contacts covers the temperature range 9‹-11‹ C., when neither the heater nor the cooler is set in operation, but outside this range the pointer 17 makes contact with either of the contacts a, b, and the heater or cooler is set in operation. Fig. 3 shows the electrical circuit, in which the mains 19 are connected to the system through switch 20 and fuses 21. Assuming that the tap liquid is too warm, contact b of the indicator is closed, an electromagnetic tilting mercury switch 30 is actuated, and the motor 13 of the refrigerating plant is started. If the tap liquid is too cool, contact a is closed, an electromagnetic tilting switch 41 is actuated, and the electric heater 10 is energized. The contacts a, b, and insulator 15 may be rotatably adjusted to vary the temperature control point. The chest 1 contains bottle trays 53, 54, and also a compartment, not shown in Fig. 1, for bottles.

Title: Telephone line concentrators or the like
IPC: H04Q3/58
Filed: 1961-10-20
Abstract: 947,429. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. (Materiel Telephonique S.A.). Oct. 20, 1961, No. 37733/61. Addition to 872,059. Heading H4K. In a concentrator as claimed in the parent Specification, having cross-bar switches at the remote concentrator and at the exchange for connecting the lines and line appearances, respectively, to the trunks, and relay and rectifier test matrices which respond to calling conditions, it is arranged that when a terminating call is received for a free subscriber when all trunks to the remote concentrator are busy, the line appearance is looped via an impedance such that ringing is tripped and a special tone is reverted to the caller, but metering is prevented. If all trunks are busy the relays CR1 . . . CR12 (one per trunk-not shown) are all operated and CXZ is energized. The relay COn is operated in response to the reception of a terminating call, but CXZ prevents operation of Cyn (which normally initiates connection to the remote concentrator), and the line appearance is looped to jamming tone transformer TF with varistor R in parallel therewith. The mean valve of the signal from the ringing generator. GCA is - 48 v. (one terminal connected to the battery pole) and the effect of varistor R is such that the mean current operates ring-trip relay SN, which connects the loop to the supervisory relay SU which is at battery voltage (- 48 v.). The resistance of the loop is high enough to prevent operation of SU. As metering is normally effected in response to the relapse of SU at the end of a call, no metering takes place in the circumstances under consideration.

Abstract: 1,146,722. Applying tapes to borders of sheets. A. BOCCA, and M. PAGANI. 23 Aug., 1966 [3 Sept., 1965; 15 Nov., 1965], No. 37797/66. Heading B8F. A tape 66 is adhered about the edge of a sheet 9, such as a shoe sole, by a fork 7, 7<SP>1</SP> which reciprocates longitudinally as its tines move to fold the bordered sheet: the sheet is fed by a reciprocating clamp 8, 9 co-operating with a fixed clamp 5, 6 and pressing the tape in place. Adhesive may be applied to the tape through a tube (74) by means of a pump driven in synchronism with the tape, or it may be applied to the sheet surfaces direct, Figs. 9 and 10 (not shown), before the tape is applied. The movable members are driven in timed relation to one another by means of eccentric cams on a shaft 1. The extent to which the members 8, 9 draw the sheet and tape forward is adjustable through an extension 40 of the member 8. A roller (65), Fig. 4 (not shown), is manually rotated to feed the tape into the guide (4). A pivoted knife 67 co-operates with a counterblade to cut the tape on actuation of a lever or pedal (not shown).

The cell is closed by crimping the can wall and applying a steel washer 18. The re-entrant may be made overlong to give good pressure with the diaphragm but need not since the pressure of subseal washer 5 on the skirt 13 ensures this. In the other embodiment (Fig. 2, not shown) the re-entrant is omitted and a current collector (9) in the form of a solid rod is used. The electrolyte may be aqueous potassium hydroxide containing zinc oxides.

Abstract: 975,049. Delivering sheets. S. D. WARREN CO. Oct. 4, 1963 [Nov. 5, 1962], No. 39225/63. Heading B6H. Apparatus for temporarily stiffening sheets travelling along a set path comprises a support structure forming part of the path, the structure including a number of laterally spaced support surfaces extending along the path, and means for applying differential air pressure across the sheets when travelling over the structure, the means being such that the pressure on the side of the sheet facing the structure is less than that on the other side whereby parts of the sheet are drawn downwardly between adjacent support surfaces to corrugate the sheet and thus to stiffen it. Sheets are delivered from a cutting machine by a high-speed conveyer 13 and deposited in overlapping fashion on a low-speed conveyer 14. Each conveyer comprises a plurality of spaced endless tapes. The middle three tapes of conveyer 13 are parallel and the outer tapes converge towards the forward end of the conveyer. A suction box 26, arranged beneath the conveyer 13, includes a number of laterally spaced supports 27 for the tapes. Between the supports are positioned a number of baffles 28. The latter extend beyond the box as at 29 into recesses between collars 21 and 22 supporting the tapes. Slots 30 are provided between the baffles and supports by means of which suction is applied to the undersides of the sheets passing thereover. Thus the sheets are corrugated transversely to stiffen the same. A suction hose 31 is connected to one end of the box beneath the level of a horizontal baffle-plate 34. A series of graduated size holes is provided in the plate 34 to distribute the air flow through the slots 30. A second high-speed conveyer 11 and suction box 33 may be provided between the cutting machine and high-speed conveyer 13.
