Title: Multi-colour ball-point fountain pen
IPC: B43K24/16
Filed: 1960-08-26
Abstract: 936,681. Reservoir pens. M. J. VON ARX. Aug. 26, 1960 [Aug. 28, 1959], No. 29535/60. Class 146 (3). A multi-colour ball-point pen comprises a two-part barrel a, d, a plurality of, e.g. 3, tubes b slidable in the barrel and containing writing units which have ink charges of different colours, an equal number of pushers e slidably mounted in the barrel, each of the pushers having one end engaged in the open end of a tube b, a plurality of springs f which urge the pushers towards a position in which the corresponding writing units are retracted within the barrel, and means for locking the pushers when the writing units are in their projected positions, the springs f returning the pushers to retracted position when the locking means are freed by actuation of any one other pusher. The barrel part d has slots e 1  in which laterally projecting lugs on the rear ends of the pushers e are guided. The pushers are also guided in slots in a web h forming part of the barrel part d. Each pusher lug has a coloured button o which denotes the colour of the corresponding writing unit. Each pusher has an abutment i which in the retracted position of the corresponding writing unit engages a stop rim n 1  on a plug n mounted in the rear end of the barrel. A selected writing unit is projected by moving its pusher e, by means of its projecting lug, to the position shown at the top of Fig. 1 against the force of the spring f, the abutment i being latched behind the front end j of the plug n in this position. A ring-shaped member l is loosely mounted near the end j of the plug n and engages in notches m formed in the pushers e when the pushers are in retracted position. If it is desired to project a different writing unit the corresponding pusher is advanced and the member l rides out of the notch m in that pusher whereby it is displaced laterally so as to move the abutment i of the pusher which is already in projected position out of engagement with the end j of the plug n. The latter pusher and its writing unit are then retracted by the spring f while the writing unit to be projected is latched in the projected position by means of the engagement of the abutment i on its pusher with the plug end j. All the writing units may be returned to retracted position by partially advancing one pusher, so as to displace the member l, and releasing it for retraction by the spring f before it is latched in the projected position.

Abstract: 448,928. Fire-extinguishing. TAPPE, W., 27bis, Vitting Strasse, Bucharest. Oct. 17, 1934, No. 29695. Convention date, Oct. 17, 1933. [Class 47 (ii)] A device for directing fireextinguishing foam to the seat of a fire consists of a telescopic pipe 6-6<11>, the rear section 6 of which is rigidly secured to a frame 5 pivoted on a turntable 4 mounted on a wheeled carriage 1. The sections 6-6<11> are braced by struts or cables 10-10<11> secured to drums 11 at the upper end of the frame. The frame is tilted, to elevate the pipe, by a cable 8 and winch 7 mounted on the turntable. The free end of the pipe is provided with a curved spout, and the rear section is adapted for connection to any suitable source of foam. The Specification as open to inspection under Sect. 91 describes a device consisting of a telescopic pipe 20, 24, 25, Fig. 1 (Cancelled), carried by a frame 12 pivoted, by a shaft 11, on a turntable 4 mounted on a wheeled carriage 1. The turntable is rotatable by gearing 5, 8 and a crank handle, and the frame 12 is tiltable, to erect the pipe, by means of cables 18 and winding drums 15 carried by a counterweight 14 mounted on the shaft 11. The inner pipe section 20 is fixed to the frame 12 and is braced by a strut 23. The telescopic sections 24, 25 are fitted respectively with collars 28, 29, Fig. 4 (Cancelled), to which are secured cables 30, 31 which pass over pulleys 32, 33 to winding drums 38, 39 whereby the sections are extended. When extended, the sections 24, 25 are braced by cables 42, 43 adapted to be tightened by winding drums 40, 41. A nozzle 26 fitted to the pipe section 25 is connected to a flexible hose 27 which extends within the pipe sections and emerges from an aperture at the inner end of the section 20 to be connected to a source of foam or other medium. Alternatively, the pipe may be formed of sections adapted to be screwed together as required and the separate hose 27 may be omitted. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to thermionic valve circuits for generating two alternating voltages whose frequencies are in harmonic relation
IPC: H03B19/10
Filed: 1946-10-05
Abstract: 617,541. Valve generating circuits. PHILIPS LAMPS, Ltd. Oct. 5, 1946, No. 29747. Convention date, Jan. 15, 1943. [Class 40 (vi)] In a circuit for generating two harmonically related oscillations, each by a separate thermionic oscillator, the outputs are coupled so that the frequency of the lower frequency oscillator is independent of, and that of the higher frequency oscillator dependent upon the voltages occurring at the coupled electrodes. The Figure shows an oscillator 1, 3 triode connected, having its frequency harmonically related to that of the oscillator 2, 4, also triode connected. With the switch 10 in the position shown, the screen grid of oscillator 2, 4 is decoupled so that its frequency is unaffected by that of oscillator 1, 3. Oscillator 1, 3, however, has its frequency synchronized by the voltage occurring across the common anode resistor at the frequency of oscillator 2, 4 which is applied to the screen grid. When switch 10 is moved to the right, the screen of the oscillator 1, 3 is decoupled and the frequency of oscillator 2, 4 is controlled to multiple of oscillator 1, 3.

Abstract: 409,348. Thermal switches. HAYWARD, L., 2, St. Paul's Avenue, Slough, Buckinghamshire. Oct. 28, 1932, No. 30282. [Class 38 (v).] Waffle irons are provided with two heatsensitive elements which co-operate to initiate a signal when a predetermined temperature has been reached. As shown, the heat-sensitive elements 11, 19 are connected to the lower iron, the element 11 outstanding horizontally from a heat-conducting member 10 depending from the lower iron so that its free end, which carries a nonconducting strip 12, rises as the temperature rises. The strip 12 carries a pair of contacts 13 which are bridged, for operation of the signal, by a conductor 25 carried by one arm of a bell-crank lever 23. The other arm has an adjusting screw 26 which contacts with the heat-sensitive element 19, so that as the temperature of the apparatus increases the conductor 25 contacts with the more slowly ascending contacts 13, and the signal lamp 27 is lighted. The top waffle iron is then swung back manually, the heating-circuit being broken by the consequent withdrawal of the pin 16<a> from between the contacts 16b. An audible signal may replace the lamp 27.
