Title: Improvements in or relating to a.c. electric circuit-breakers of the gas-blast type
IPC: H01H33/70
Filed: 1944-10-06
Abstract: 580,672. Gas-blast switches. REYROLLE & CO., Ltd., A., and AMER, D. F. Oct. 6, 1944, No. 19180. [Class 38 (v)] In a gas-blast circuit - breaker, a passage is provided so that some of the gas may by-pass the nozzle-bore and flow from the high-pressure side to the lowpressure side of the nozzle to scavange and cool any insulation otherwise subject to the destructive effects of arcing. In Fig. 1, the blast transfers the arc from a contact B, through an insulating, or insulated conducting, nozzle C to contact E connected to the metal casing A and the contact. B. Gas also passes through passages F' in the insulating bush F into the annular compression chamber F' and thence through the annular throttling space F' to scavange and cool the exposed surfaces of the nozzle C and bush F. To protect insulation H', H' supporting and surrounding an auxiliary electrode H used in "resistance switching," Fig. 2, high-pressure gas is conveyed to annular spaces H', H' by a conduit H<5>. In Fig. 3 (not shown) the "resistance" electrode is parallel to the axis of the nozzle and its bushing H<1> is surrounded by the scavanging air within a tubular casing disposed mainly outside the main casing. The bush H<3> diverges within the main casing. In Fig. 4, (not shown), an external " resistance " electrode together with its bushing and casing is bent through 180‹ so as to enter the main casing and cause the scavanging gas to oppose the gas-blast.

Title: Improvements in or relating to electric time alarm systems
IPC: G04C21/32
Filed: 1933-07-08
Abstract: 408,483. Time-alarm signals. CITTERIO, S., 30, Via Vigone, Turin, Italy. July 8, 1933, No. 19417. Convention date, July 9, 1932. [Class 118 (ii).] In a time-alarm signalling system more particularly for hotels, a master clock transmits impulses for controlling step-by-step secondary clocks having adjustable contact arrangements to facilitate operation of alarms at predetermined times. The minute hand of the master clock 1 drives a cam 2 which operates contacts 3, 4 at intervals, e.g. every fifteen minutes, to impulse a relay 5. The relay 5 is supplied at low-voltage through a transformer T and operates a relay 6 which operates the stepping magnet 7 of the secondary clock over high voltage circuits. The secondary clock has a contact arm 10 which co-operates with an apertured ring adapted to receive a contact plug 13 in a position corresponding to the time at which an alarm bell 14 is to be operated. At the expiration of the time the circuit of the bell is completed through the arm 10 and plug 13. A relay 15 is included in the alarm circuit and when operated actuates an indicator in the servants' quarters to indicate the secondary clock affected. An auxiliary and impulsing equipment comprising pins 1<a> co-operating with a contact 16 and brought into use by a switch 17 may be provided in the master clock to ensure the production of relatively long impulses and the synchronous operation of the secondary clocks during a setting operation of the master clock. This arrangement avoids faulty operation of the secondary clocks as the result of fast impulsing by the cam 2 during the setting operation. An alarm 20 is provided to indicate when the master clock requires rewinding. The clock spring 18 unwinds and engages contact 19 near the end of the running period.

Abstract: 799,283. Compressing rolls of cotton-wool. HYTAKOS AKT.-GES. June 22, 1956 [June 23, 1955], No. 19468/56. Class 94(1). A machine for compressing rolls of cottonwool comprises a series of pairs of pivoted jaws 12 mounted on pivot pins 11 passing through a ring 10 and a plate 9 which is carried by driven shaft 4. The lower ends of the pins 11 carry lever arms 13, Fig. 3, fitted with rollers 14 engaging a fixed cam 15, whereby the jaws are periodically opened and closed as the shaft rotates. Each pair of jaws co-operates with a pressing member 19 which is slidable radially in guides on the underside of the plate 9 and carries rollers 18 and 21 engaging fixed cams 17 and 20 respectively. Heated rolls 30 of cottonwool are fed in succession into the spaces between the open jaws as shown in Fig. 2. Each pair of jaws is then closed as the shaft 4 rotates and its associated member 19 is moved outwardly by the cam 17 to compress the roll held between the jaws to a cylindrical shape. The roll is held in the compressed state until the jaws reach an ejection station where they are opened and the member 19 is moved further outwardly to eject the roll. The cam 20 then returns the member 19 to its initial position ready for the reception of another roll. The roller 18 and cam 17 are frusto-conical in shape so that the stroke of the members 19 may be adjusted by raising and lowering the cam. For this purpose the cam is carried by an axiallymovable bush 31 having a threaded lower end engaged by a nut 25 which is rotatable through bevel gearing 23, 24 by a shaft 22.

Title: Improvements in or relating to multi-stage high-frequency amplifiers
IPC: H03G1/04
Filed: 1956-06-25
Abstract: 793,422. Valve or transistor amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 25, 1956 [June 28, 1955], No. 19611/56. Classes 40 (5) and 40 (6). In a tuned multi-stage amplifier in which the impedances of two or more valves or transistors vary to a different extent when a bias is varied, the circuit impedances are proportioned in inverse ratio to the degree of variation of the valve or transistor impedance to which they are connected. As applied to a frequencymodulation receiver in which successive stages 7, 12 are biased from the grid currents in grid circuit resistors 8, 16 respectively, so that the later stage 12 handles the larger signal and so produces the biggest change in input capacity when the signal level changes, the L/C ratio of the tuned circuit 14 feeding the later stage 12 is made correspondingly smaller than that for the earlier stage 7. The L/C ratios of the primary circuits of the band-pass filters may also be chosen in a similar ratio. As an alternative to adjusting the L/C ratios the valves may be connected to suitable tapping points on the circuits.

Filed: 1955-07-07
Abstract: 811,303. Fault testing. ERICSSON TELEPHONES Ltd. May 11, 1956 [July 7, 1955], No. 19626/55. Class 37. An insulated cable 1 (Fig. 1) wound on drum 4 with its conductor earthed is drawn by motordriven drum 5 through tubular electrode 2 comprising two spring-loaded wire mesh channel sections and through an adjacent solenoidoperated ink marking stamp 3. The electrode is connected over switch S (Fig. 2) in parallel with electrostatic voltmeter M to insert a capacitance represented by C1 in a normally balanced bridge network completed by variable balance capacitance C2 and resistors R1, R2, which is energized by mains transformer T2 supplied over closed contact A4. Failure of insulation under the alternating voltage between electrode 2 and earth generates a spark short-circuiting capacitance C1 to unbalance the bridge and excite transformer T1 whose output is rectified by double diode V2 to a unidirectional voltage triggering the screen of gas-filled tetrode V1 whose threshold is set by variable potentiometer circuit R3, R6 energized from a D.C. source supplying the tetrode anode through one side A of a double-wound relay - and normally closed 3 switch KS. On the tetrode firing, the relay operates, holds over contact A1, closes contacts A2, A3 to energize an indicator lamp N, alarm bell B and marking stamp 3, and opens contact A4 with other contacts (not shown) to deenergize the bridge circuit and disable the drive motor of drum 5. The precise fault position is then found by re-starting the apparatus by momentarily re-opening switch KS to reset tetrode V1 and traversing the cable with a hand electrode 8 substituted by switch S, comprising an insulating sleeve enclosing a metal rod which may be brought into contact with the cable through slot 16 of the sleeve. The apparatus may be assembled with an electric vulcanizer for repairing insulation faults.
