Abstract: 1418560 Particulate systene polymers; foamable products therefrom SEKISUI KAGAKU KOGYO KK and SEKISUI KASEIHIN KOGYO KK 27 July 1973 35993/73 Headings C3P and C3C Particulate styrene polymers (styrene hereinafter includes derivatives thereof and their mixtures) are produced by suspension polymerization in which styrene polymer particles with a size of 0À4 to 1À8 mms. are suspended in water and a catalyst solution comprising 60- 100 wt. per cent of the total catalyst to be used and 1-10 wt. per cent of the total styrene monomer to be used, and a monomer-solution comprising 90-99 wt. per cent of the total monomer to be used and 0-40 wt. per cent of the total catalyst to be used, are independently added to said suspension in a dropwise fashion whilst carrying out the polymerization. The catalyst solution and the monomer solution may contain 0À0025-2 wt. per cent of a surfactant (based on the total monomer), which is soluble in the styrene monomer. The catalyst solution may either be a solution in the styrene monomer alone, or a further solvent such as toluene may also be present. A foaming agent may be present during the polymerization in an amount of 2-20 wt. per cent (based on the weight of particles produced) (n-pentane was used in Example 7) and in Example 5 such an agent is added after polymerization-the particles produced are suspended in water using magnesium pyrophosphate and sodium dodecyl benzene sulphonate, and then propane and butane are fed into the vessel under pressure, whereupon they are absorbed by the suspended polymer particles which are thus rendered foamable. The expandable particles are foamed by immersion in boiling water.

Title: Methods of and means for automatically controlling the rate of flow of granular material
Inventor: NEWMAN MICHAEL
IPC: G05D7/06
Filed: 1962-09-25
Abstract: 1,063,351. Automatic flow control, fluid pressure servomotor systems. COAL INDUSTRY (PATENTS) Ltd. Dec. 6, 1963 [Sept. 25, 1962], No.36402/62. Headings G3P and G3R. A first stream of particulate material flowing at a variable rate is mixed with a second stream flowing at a substantially constant but adjustable rate, the difference between the rate of flow of the first stream and a reference rate being used to control the rate of flow of the second stream with modification in dependence on the error between the sum of the two rates of flow and the reference rate. In Fig. 1 a steady flow of coal is supplied by a vibratory feeder 4 from a hopper 3 to a conveyer 1 the output of which is mixed with the output of a conveyer 2 the supply to which fluctuates. The rate of supply of coal by conveyer 2 is measured by a weighing section 14 the variable signal from which is compared in a device 15 with a signal X representing a desired total flow so that the difference is effective to adjust the feed of the vibratory feeder. The total flow is computed by adding in a device 16 signals from weighing sections 12, 13 appropriately positioned on the two conveyers and the output of device 16 is compared in a damped control unit 17 with the signal X representing the desired total flow so that any error controls a device 18 to modify the signal from device 15 controlling the vibratory feeder 4 and ensure the desired total flow. In one modification a single weighing section replaces the two sections 13, 14 and in another a weighing section of a conveyer handling the total flow after mixing replaces the two sections 12, 13. Controlling the speed of conveyer 1 is referred to. Fluid-pressure or electrical signals may be employed.

Title: Improvements in reels for carrying inked ribbons in printing machines.
IPC: B41J17/14
Filed: 1967-08-08
Abstract: 1,180,772. Typewriters &c. SOC. INDUSTRIELLE BULL - GENERAL ELECTRIC. 8 Aug., 1967 [31 Aug., 1966], No. 36456/67. Heading B6F. Ink-ribbon reels.-A reel for holding, in a typewriter, an inked page width ribbon, including a carbon ribbon or a ribbon coated with material having optical or magnetic properties, has on at least part of its external surface an adhesive coating which is covered by protective ribbons disposed parallel to the reel axis, each ribbon being removable to expose a portion of the coating to enable the end of an ink ribbon to be applied to the coating and adhered by pressure. In one form, Fig. 5, the reel 200 is covered with sheet material 201 having an adhesive surface to which a number of protective ribbons 202 are adhered. To attach the leader tape of an ink ribbon to the reel, one of the ribbons 202 is removed by means of a flap 213 thereon, the leading end of the leader tape is aligned as shown by means of the flap of the adjacent ribbon, and the leader tape is then pressed against the exposed adhesive strip. Instead of the flap 213, each protective ribbon 202 may have a tab at one or both ends (Figs. 3, 4) by which it can be easily detached. In this construction, the leading edge of a leader tape is aligned against an edge of a ribbon 202 adjacent to the exposed area. According to a modified construction (Fig. 6), the protective ribbons 202 are adhered to axially-extending adhesive strips on a covering of impermeable material attached to the reel. Axially-extending grooves or projecting flutings in the covering separate the adhesive strips and serve for aligning the leading edge of a leader tape. The reels may be used repeatedly for securing fresh ink ribbons so long as there are unused adhesive strips thereon. Reversal arrangements; ribbon guides.-The leader tapes at each end of the ribbon are wider than the ink ribbon and each carries a transverse bar, one of which engages one of two blades 110 of a switch CI to reverse the ribbon feed when the ink ribbon of the associated reel 103 or 104 is nearly completely unwound. To attach a new ink ribbon to a reel which is in position 103, for example, a reel complete with a new ribbon is inserted in position 104, and its leader tape is pulled by hand over a fixed plate 116 spaced from the switch blade 110 so that the blade is not operated, then over a flexible sheet 119 and rollers 117, 112 and is attached as already described to the reel 103. The ribbon is then tautened by the operator in known manner. The flexible sheet 119 is disposed between the paper 139 to be printed and the ink ribbon in a zone a little below the printing line, which as shown is where hammer mechanism 114 strikes the paper against type on a drum 102 to print a line. In this position the sheet 119 prevents spotting of the paper by ink from the ribbon. In addition to machines employing type drums, the reels may be used in line-by-line printers having a set of type-wheels, a system of toothed type-carrying racks, or an endless band carrying type characters.

Title: Improvements relating to delustred artificial silks
IPC: D06P1/673
Filed: 1933-12-28
Abstract: In a process for dyeing regenerated cellulose artificial silk which has been delustred by means of titanium dioxide, the material before or after dyeing is treated with a water soluble salt containing chromium.  The treatment may consist in immersing delustred viscose in a hot aqueous solution of the chromium salt and then with or without rinsing and/or drying, applying the direct dye in the usual way.  In an example the silk is treated for half an hour at 85 DEG C. in 0,3 per cent potassium bichromate solution to which 0,2 per cent formic acid may be added if desired, or in 0,5 per cent chromium chloride solution, is rinsed, and then dyed with 2 per cent of the substantive dyestuff chlorazol Fast Helio BK (Colour Index No. 390) with addition of 10 per cent of Glauber's salt for \ba3/4\be hour at 85 DEG  C.  Chromium fluoride is another suitable chromium salt and the treatment may follow the dyeing.

Title: Improvements in apparatus producing or using ultra high-frequency electric oscillations
IPC: H01J25/68
Filed: 1934-12-20
Abstract: 432,781. Valve generating, modulating, and detecting circuits. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Materiel Telephonique Soc. Anon. ; 46, Quai de Boulogne, Boulogne-sur-Seine, France) Dec. 20, 1934, No. 36548. Convention date, June 30. [Class 40 (v)] The supply voltages for the grid and plate of an ultra-short-wave oscillator or detector of the vibrating electron type are taken from a potentiometer across the supply source in such manner that variations in supply voltage do not affect the frequency of oscillation, but affect the output linearly. The supply source S is connected through a choke coil 20 to a potentiometer 5, one end of which is connected to the circuit of the cathode 2. A high-voltage tapping 9 is connected to the positive grid 3, and a low-voltage tapping 10 is connected through a battery 7 and a potentiometer-battery combination 6, 8 to the negative reflecting-electrode 4. By suitable choice of the relative positions of the tappings 9, 10, fluctuations in supply voltage S do not affect the oscillation frequency. The oscillations are fed to or from the valve by parallel wires connected to opposite ends of the grid 3 and to a dipole 13. Modulation by speech or other currents is effected by a transformer 14, the secondary of which is connected through blocking condensers 18, 19 across the potentiometer 5. The modulating-voltages are thus applied to the valve electrodes in such a ratio that the frequency is unaffected. At the same time, the modulating-voltage varies the power or amplitude of the generated wave and by suitable choice of the working-point, linear modulation is secured. When the system is used for detection, the valve is operated just short of the oscillating point. For super -regenerative reception, a local quenching-frequency may be injected through the transformer 14.

Title: Monitoring system for use with amusement game devices
IPC: G06F17/40
Filed: 1975-09-08
Abstract: 1512857 Selective signalling; gaming machines BALLY MFG CORP 8 Sept 1975 [13 Sept 1974] 36890/75 Headings G4H and G4V A monitoring system comprises a plurality of game devices electrically connected to respective couplers connected to interface means which sequentially generates addresses of portable transponders, and at least one portable transponder which responds to its address when connected to one of the couplers by transmitting information to the interface means. When a jackpot occurs on a game device (slot machine), a light and bell are actuated as at signal to an attendant to plug a transponder he is carrying into the coupler on the game device (there may be a plurality of attendants each with a transponder). When addressed by the interface unit over a twisted conductor pair, the transponder transmits the identities of the game device and transponder, the winning condition and whether the game device door has been opened since the last communication, to the interface means which sends it to a computer. (The information, apart from the transponder identity, is supplied to the transponder from the coupler). The computer returns a signal indicating the amount to be paid by the attendant and this is displayed on a 4-character 7- segment light-emitting-diode display on the transponder. Messages are transmitted twice with a check comparison. Once a transponder has been inserted in a coupler, it is locked in until the transaction has been completed and the game device operated again (insert coin and pull handle). The interface means includes a counter for addressing the transponders and communicates with them in bi-phase form. The computer may produce, accounting records, performance logs and maintenance schedules.
