Title: A base plate carrying bristles for brushes
IPC: A46B3/02
Filed: 1950-03-15
Abstract: 700,294. Stocks ; fixing bristles. MORTIMER, H. June 7, 1950 [March 15, 1950], No. 6478/50. Class 19 A base plate having bristle tufts with enlarged bases secured therein for forming into a brush is constructed from a substantially unyielding solid material and is formed on one face with one or more grooves or slots which are open at one end at least and are enlarged and shaped at their lower or inner portions so as to receive and co-operate with the enlarged tuft bases when these are slid into the grooves or slots from the open end or ends whereby the tufts are anchored against withdrawal in the direction of their length, there being sufficient space provided in the grooves or slots for the insertion therein of plastic or adhesive material to additionally fix the tuft bases. The bristles may be of any suitable fibre or filament, natural or artificial, e.g. nylon, which can be used to form an enlarged base for the tufts and the base plate may be of wood, metal, plastic or other suitable unyielding material and may be of any width according to the number of slots required, thus a grainer's dragging brush would require only one slot whereas a whitewash brush may have one, two, three or more slots. The bases of the bristle tufts may be enlarged either by fusing with heat or by sticking together with a plastic or adhesive material and will be inserted in the plate by sliding into the grooves and further fixed by pouring into the grooves a plastic adhesive which expands on cooling. The base plate is then fitted into a metal ferrule or stirrup and a handle inserted, e.g. as shown in Fig. 3 of the drawings. The grooves or slots may be enlarged at the bottom by a longitudinal part-circular bore as shown in Fig. 2 or may be of inverted " T " form in which case the sides of the slots may either be parallel Fig. 6 (not shown) or may diverge upwardly as in Fig. 4. The tufts may be reinforced with pieces of wire or rod as indicated at 6.

IPC: H01L47/02
Filed: 1967-02-14
Abstract: 1,146,557. Gunn effect circuits; multiplex pulse signalling. STANDARD TELEPHONES & CABLES Ltd. 8 Feb., 1968 [14 Feb., 1967], No. 6924/67. Headings H3T and H4L. [Also in Division H1] In a circuit arrangement comprising a device consisting of a body of semi-conductor material exhibiting high-field instability effects (e.g. Gunn effect) provided with a pair of ohmic contacts between which a field is established, and one or more auxiliary electrodes through which the transit of a domain is detected, a voltage in excess of the threshold valve is continuously applied between the ohmic contacts and an input signal for modulating the voltage across the travelling domain superimposed on it. The device may consist of N-type gallium arsenide or phosphide, high resistivity germanium or a piezo-electric material such as cadmium sulphide, with auxiliary electrodes capacitively coupled to the body through a silica layer, though ohmic electrodes may be used if the output circuit impedance is high enough. The auxiliary electrodes may be evenly or unevenly spaced along the body or disposed in spaced groups. One electrode is associated with each output circuit, but it is also possible to connect a pair of closely spaced electrodes each comparable in width with a domain into each output circuit. In the communications system shown in Fig. 5 elements of identical dimensions are used as transmitter and receiver elements. The transmitter elements have single pick-off electrodes 8 disposed at different points along their lengths and the receiver a pick-off electrode corresponding to that of each transmitter. In operation high field domains are synchronously initiated in the transmitter and receiver elements, and pulses applied at inputs A-D as the domains are passing the pick-off electrodes in the respective devices determine the instantaneous field across the domain and hence the magnitude of the pulses derived from the pick-offs, which are applied to the receiver over a common link 10, 11 to determine the field across the domain in the receiver element to produce outputs at pick-off electrodes A<SP>1</SP>-D<SP>1</SP> corresponding to the input pulses at inputs A-D respectively.

Title: Improvements in or relating to power transmission mechanism
IPC: B23C9/00
Filed: 1945-03-20
Abstract: 596,147. Variable-speed epicyclic gearing. VICTORIA MACHINE TOOL CO., Ltd., SELBY, J., and FRYE, J. March 20, 1945, No. 6985. [Class 80(ii)] In a power transmission applicable to machine tool reciprocating tables and of the kind having a driven element rotated from two driving elements each giving a different speed ratio when operated with the other stationary, the power input mechanism to the higher speed ratio element is of such a nature as to preclude drive from the said element through it, so that when the lower speed ratio element alone is powered, the higher speed ratio element is automatically held stationary. As shown, the power input mechanism to the lower speed ratio element is also irreversible. Two worms 5, 4, Figs. 1 and 2, driven directly and through change-speed gearing respectively from two electric motors 3, 2, irreversibly drive worm wheels 7, 6 freely mounted on an output shaft 1 connected to the traversing shaft (not shown) of a milling machine. The worm wheel 7 carries two layshafts 9 whose stepped planets 10, 11, of slightly differcnt size, gear respectively with a pinion 12 fast on the shaft 6 and with a pinion 13 fast on the shaft 1. When the wheel 6 alone is powered, the stationary layshafts 9 transmit an approximately direct drive. When the wheel 7 alone is powered, the resultant epicyclic motion of the layshafts 9 gives a much lower speed ratio. The motor 3, Fig. 2, drives the worm 5 through, a two-speed countershaft gear by belt drive to a pulley 15 freely mounted on a primary shaft 16 and fast to a pinion 19. A gear 18 splined on the shaft 16 is slidable under the action of a hand lever 35, Fig. 2, to engage the pinion 19 either directly through dogs 25, 26 or through countershaft gears 20, 21. Pick-off gears 23, 24 transmit the drive from the shaft 16 to the worm shaft 17. The motor 2 has a plugging switch 36 for rapid stopping. The motors may be run simultaneously, and automatic control such as is described in Specification 596,207, [Group XXXVII], may be used. The traversing shaft may be connected to the machine table by a pinion and rack instead of the usual scrcw and nut.

Abstract: <PICT:0780851/IV (a)/1> <PICT:0780851/IV (a)/2> A wet-spinning process for the production of filaments of cellulose acetate having an acetic acid yield of 52-62 per cent, preferably 58-62 per cent, comprises the steps of extruding into a coagulating bath a solution of cellulose acetate in an acetic acid/water solvent, the proportion of acetic acid to water in the solvent being within the limits contained between curves A and B of Fig. 2 and the coagulating bath containing 35 per cent by weight or less of acetic acid and being at a temperature of 25 DEG  C. or less, and applying stretch to the extruded filaments while still in the coagulating bath, e.g. while between jet 3 and first godet 4 (see Fig. 1), such stretch being additional to the stretch required to counteract the tendency of the filaments to shrink. The spinning solution is suitably brought to 35-65 DEG  C. before reaching the spinning jets, and the temperature of the coagulating bath should not be less than 5 DEG  C.; the preferred range is 8-18 DEG  C.  A minor proportion of ethyl acetate may be incorporated in the coagulating bath, where it acts as a softening agent. Delustring pigments such as titanium dioxide may optionally be added to the spinning solution.  The stretch imparted to the filaments in the bath should not be less than 2.8 per cent immediately after the point of extrusion.  Examples are given. Specifications 337,366, [Class 2 (ii)], and 652,844 are referred to.
