Title: Improvements in or relating to the manufacture of tubular glass containers
Inventor: ASHFORD ERNEST
IPC: C03B23/11
Filed: 1957-05-16
Abstract: 825,382. Tubular glass containers. JOHNSEN & JORGENSEN FLINT GLASS Ltd. Jan. 15, 1958 [May 16, 1957], No. 15598/57. Class 56.  A method of making glass containers such as ampoules from glass tubing comprises feeding lengths of glass tubing successively into a machine and forming a bottom in each length before any containers are made therefrom. The mechanism specified comprises an arm 1 on a pivot 2, at a position outside the pitch circle upon which the chucks of a conventional machine for making glass containers of the kind referred to revolve, carrying a slidable member 4. Contact of rollers 6 with the rotating chucks each of which holds a vertical piece of glass tubing produces sliding of member 4 which is transmitted to roller 44 which engages with cam surface 45 and imparts thereby a downward movement to the jaw holder 14 along with the sliding movement which is also transmitted to jaw holder 14. These movements of jaw holder 14 through a system of gears and tappet rods result in jaws 20 being raised and brought to bear on the glass tubing below section heated by gas burner 7. Further movement of the chucks results in a small portion of glass tubing being removed from the lower end in such a way that a bottom is formed in the tube as the small portion is drawn away.
Patent GB-563181-A (GB)
Title: Improvements in the dyeing of cellulose acetate textile materials
IPC: D06P5/22
Filed: 1942-11-05
Abstract: Cellulose acetate textile material is subjected to the action of a 23-40 per cent aqueous solution of caustic alkali, the temperature and duration of the treatment being such that the acetyl value is not reduced by more than 7, and is then washed and thereafter is dyed with a direct dyeing dye for cellulose acetate. Materials which have been pre-treated with the caustic alkali are more deeply dyed by the cellulose acetate dyes, e.g. 1 : 4-diamino-anthraquinones, and the dyeings are more resistant to fading when exposed to an acid atmosphere, e.g. one containing combustion products of coal gas.  The caustic alkali may be sodium or potassium hydroxide.  The treatment is useful in the dyeing of yarns of high denier and high filament count.  The action of the alkaline agent may be stopped by washing with water and neutralizing with acid.  In an example, a cellulose acetate fabric is subjected while free from tension to the action of a 33 per cent solution of caustic soda for 30 seconds.  The fabric is washed and then dyed in a bath containing Celliton Blue AF, xylene and turkey-red oil mixture, and water at 80 DEG  C.  In another example, cellulose acetate fabric is treated with a 37.5 per cent caustic potash solution for 60 seconds and then after washing, it is dyed with a solution containing S.R.A. BLUE IV, xylene and turkey-red oil mixture, and water at 80 DEG  C.  The Specification as open to inspection under Sect. 91 comprises also the use of other alkaline reagents for the pre-treatment, e.g. sodium silicate, barium hydroxide, sodium phosphate, methylamine, propylamine, and tri-ethanolamine, and the treatment is described as applicable to cellulose ester materials in general and to films.  This subject-matter does not appear in the Specification as accepted.

Title: Improved method of and means for supercharging 2-stroke cycle internal combustion engines
IPC: F02B25/00
Filed: 1941-12-05
Abstract: 553,978. Two-stroke engines. SAMMONS, H., and ARMSTRONG WHITWORTH & CO. (ENGINEERS), Ltd., Sir W. G. Dec. 5, 1941, No. 15723. [Class 7 (ii)] A two-stroke engine is supercharged by admitting the charge from a blower or reservoir in two separate portions passing through the same inlet ports, the first being trapped in a chamber b surrounding the inlet ports a at a pressure somewhat above atmospheric before being admitted to the cylinder, while at a later and separate period the second portion passes direct from the blower or reservoir to the cylinder. In the arrangement shown, both portions are supplied by a blower through a rotary valve d having a port e adapted to register with an opening c leading to the chamber b. The valve is driven by chain or other gear at twice engine speed and admits charge to the chamber b twice in each revolution, first when the ports a are closed and secondly after the ports a have opened to admit charge from the chamber b to the engine cylinder. The exhaust valve or port preferably closes at such a time that substantially all the second portion of the charge is retained in the cylinder. The chamber b at its entry end may be divided into two by an internal rib or partition. In a multi-cylinder engine in which the periods of opening of the inlet ports in different cylinders overlap, different groups of cylinders may be supplied by separate blowers. The invention is applicable to engines in which the entry of air is assisted by depressions due to the action of the exhaust gases. Specification 553,965 is referred to.

Title: Intercommunication systems
IPC: H04M9/00
Filed: 1962-04-25
Abstract: 993,268. Intercommunication systems. STANDARD TELEPHONES & CABLES Ltd. (Standard Elektrik LORENZ A.G.). April 25, 1962, No. 15730/62. Heading H4K. In an intercommunication system comprising master stations and substations, amplifiers and selective switching means are located only in the master stations but the direction of the amplifiers, i.e. for incoming or outgoing speech, is controllable by the substations and on initiation of a call by a substation an electronic oscillator at the master applies ringing signals to a ringing circuit extending between the two stations so as to actuate sound transducers thereat. A substation comprising a microphone-loudspeaker SW and a talk-listen key Spt is depicted in Fig. 5 and a diagram of a master station is shown in Fig. 4. In the latter, jumpers I associated with banks LT(n)I, LT(n)II of a line selection switch LT are dispensed with if the corresponding line ab extends to another master, while jumpers II are removed for lines to the substations. When a master is called (closing Spt in a substation or the appropriate line key in another master) an identification lamp AL lights and a transistorized ringing generator G oscillates since the loop on the calling line completes the path for a battery U (local or central). The master operates the appropriate line key to remove the ringing and identification circuits and actuates his speech key SpT whereby the amplifier Vr (outgoing) is put in the speech path and lamp BL lights. This lamp serves to indicate whether or not the speech key of the distant station (assuming that this is a master) is operated since if it is communication cannot take place. If the caller is a substation however and the master station speech key SpT is operated then lamp BL lights (in a circuit via Wi2) irrespective of the position of the speech key Spt in the substation and thus the master station can speak to, and without interruption from, this substation. However, if the master station speech key SpT is not actuated then amplifier Vr comes under the control of a relay R which energizes whenever the substation key Spt is operated and thus causes Vr to act as an incoming amplifier. A. master can communicate directly with his substations since the latter have no ringing facilities and conference calls can be set up by the simultaneous operation of more than one line key.

Filed: 1967-04-07
Abstract: 1,182,011. Train control. TELEFONAKTIEBOLAGET L. M. ERICSSON. 7 April, 1967 [7 April, 1966], No. 16167/67. Heading B7N. [Also in Division H4] In an arrangement for transmitting information in binary form to railway trains via a trackside conductor, the information is transmitted as frequency modulated messages, one for each train in a section of track, preceded by a start signal which serves to synchronise the clock pulse generators of the train carried receivers. Square wave generator O.S. in the transmitter, Fig. 3, feeds a clock pulse logic unit TP which supplies output pulses consecutively on the four lines Tt during a clock pulse period. Data from unit D is fed to coder K where it is transformed into a pulse train in which positive going or negative going transitions occurring at the mid point of a bit period represent binary "1" and "0" respectively. The start signal A5 is added to the signal train and comprises eight bit periods at a fixed potential followed by four bit periods of alternating square wave potential. The signal train A4 frequency modulates a carrier in unit FM which supplies a signal A5 to energize the trackside conductor. The train carried receiver, Fig. 4, includes a conventional portion 41 which supplies a demodulated signal on line A7 and a carrier present signal on line A6. The demodulated signal is supplied via a limiter amplifier F2 to an integrator II, a differentiator d1 and to a decoder logic unit AL. The integrator detects the constant potential level of the start signal and issues an output signal to cut-off timing pulse oscillator TO, to switch control and timing pulse logic circuits SL and TL to their zero condition and to lock the output of decoder logic AL to zero. At the end of the constant potential period the integrator output drops and the oscillator restarts at a frequency synchronized by the output signals supplied by the differentiator dl. The oscillator output is supplied to unit 44 which supplied clock pulses in sequence on lines tl-t4. These pulses are used in the control logic unit SL for ensuring correct polarity of the synchronizing signals supplied to the oscillator TO from the differentiator dl and also in the decoder unit AL for decoding the demodulated signal by a sampling process.
