Patent GB-1512071-A (GB)
Title: Process for concentrating latices by ultra-filtration
IPC: C08L27/06
Filed: 1975-04-28
Abstract: Latices obtainable by emulsion polymerisation of vinyl chloride, optionally with other copolymerisable monomers, are concentrated. Ultrafiltration through a semipermeable membrane made from a synthetic polymer removes water and low-molecular-weight substances dissolved therein from the latex. The membrane should retain substances from a molecular weight of 5,000 to 100,000 and is treated before the ultrafiltration with an aqueous emulsifier solution. This considerably reduces the formation of deposits on the membrane during the ultrafiltration. The pretreatment of the membrane is carried out using emulsifiers as used for the emulsion polymerisation of vinyl chloride.
Patent GB-1146610-A (GB)
Title: Improvements in or relating to push button tuning arrangements for radio receivers
IPC: H03J5/12
Filed: 1966-04-22
Abstract: 1,146,610. Push-button tuning. TELEFUNKEN PATENTVERWERTUNGS - G.m.b.H. 22 April, 1966 [23 April, 1965], No. 17611/66. Heading H3Q. A push-button tuner wherein each button selects a frequency band has a separate knob for tuning within the bands, arranged so that when a button is pressed the tuning knob is automatically coupled to, and alters the position of, the adjusting member actuated by the button. Preferably, when the tuning knob is depressed the button is released and the knob stays depressed until another button is pressed, but the buttons and knob may each be selfreleasable. In Fig. 1 each push-button 23 carries a nut 33 which actuates a rocker arm 35 (shown cut away) to operate the tuning capacitor or variometer (not shown). The button spindle 22 and the tuning knob spindle 6 have shaped portions at their ends, 41/42 and 9/10 respectively, which engage detents 11, 15 for self-locking and mutual release, both spindles being biased to the left by springs 8, 26. The amount by which each button moves the rocker arm depends on the axial position of a nut 30 which has a smooth lower edge for engagement with the base-plate 1 to prevent rotation. When a button is pressed, a pin 38 on its spindle engages a recess 37 in a gear 36 which is normally free on the spindle. At the same time the tuning spindle 6 is released so that a pin 21 engages a similar recess on a meshing gear 19 normally free on the tuning spindle. Rotation of the tuning knob then shifts the nut 30 axially and alters the tuning via rocker arm 35. The point 10 of the tuning spindle also operates a mains on-off switch 16. Backlash in the nut 30 is prevented by a spring 33 which engages pins 32 and passes through a slot in the nut (Fig. 2, not shown). The gear 36 is urged into contact with the pin 38 by a spring 39, and the frame member has projections 40 to reduce friction as the gear rotates. The movement of the button spindle to the left is limited by a split ring 27 and a ring 28 of resilient material. The button is also urged against another split ring 25 by a spring 24, and carries a number of noses 43 which press on a switch bar 44 to perform band switching. The band is changed by pulling the button out against the spring 24 and rotating it so that a different nose 43 engages the bar 44. When more than two buttons are used, their spindles and that of the tuning knob are all in line and carry gear-wheels of the same diameter and pitch so that all the gears rotate simultaneously. The tuning knob is preferably in the centre of the line. The mains switch may be on a bracket (4 in Fig. 2, not shown) attached to the frame member 3.

Title: Improvements in automatic musical instruments
Filed: 1922-06-27
Abstract: 204,749. Wade, H., (Acolian Co.). June 27, 1922. Expression-controlling; tune sheets.-An automatic musical instrument is played from a perforated tune-sheet on which the music is separated into two parts, the expression of one part being automatically controlled and the expression of the other part being controlled by the performer using the expression of the first part as an aural guide. In the construction shown in the Figure, the action 3 has indirect connection with the suction-reservoir 6 through a port 8 controlled by a knife-valve 9 pivotally connected both to the movable board 7<c> of an ordinary governor-bellows and to the expression bellows-combination 15<a> - - d, and direct connection through a port 27b controlled by a valve 27d. The expression of the accompaniment played by the perforations 33 of the tune sheet is produced by the marginal perforations 25 operating the bellows 15<a> - - 15<d> through valves 17. The solo perforations 34 are out of alignment with the perforations 33, and the marginal perforations 29, which by means of a primary valve 32 open the direct passage 27b for sounding the solo notes, are slightly in advance of the perforations 34. The air-tension in the reservoir 6 is varied to give expression to the solo notes, by the performer varying the intensity of his pedalling, utilizing the expression automatically given to the accompaniment as an aural guide. The expression of the accompaniment may also be indicated to the performer by a varying line l on the tune sheet. The automatic operation of the valve 27<d> by the valve 32 and perforations 29 may be dispensed with, and a manual slide-valve controlling a V-shaped port substituted, to be operated by a hand-lever at the commencement of each solo note. If a power-driven bellows is used, this slide-valve will be opened by the operator to varying extents corresponding to the expression of the harmony. It is also stated that the expression of the solo notes may be automatically controlled, the performer controlling the expression of the harmony. Reference has been directed by the Comptroller to Specifications 7681/12, 468/13, 581/13, 16157/15, 176,861, and 186,702.

Filed: 1975-04-30
Abstract: 1509799 X-ray dosimetry SIEMENS AG 30 April 1975 [2 May 1974] 18086/75 Heading G1A An x-ray apparatus includes beam-area adjusting diaphragm plates 5, 6 and a measuring device e.g. an ionisation chamber 12 disposed in a housing 11  secured at the outlet of the diaphragm plate housing 4, the device having two concentric x-ray measurement fields disposed concentrically in a common plane with the smaller field 15 being so dimensioned that even with the narrowest beam focussing the field area is wholly occupied by x-rays whilst the larger field 16 is so dimensioned that even with the widest beam focussing no part of the beam falls outside the total area of the two fields 15, 16. Currents from these fields are converted into voltages by amplifiers 17, 18 respectively and the resulting signals obtained at terminals 27, 24 respectively are representative of incident dose and dose-area product of the incident x-ray field. Thus the dose rate representing signal from amplifier 17 is integrated at 25, 26 to yield the dose. The dose-rate signal is added at imput 21 to the signal from amplifier 18 which represents the area of the beam leaving the housing and the resultant signal is integrated at 22, 23. The signal from amplifier 17 also provides a measure of exposure time on timer 29. A signal from ionisation chamber 9 disables the x-ray tube 2 when suffucient radiation has passed to the x-ray film cassette 10.
