Title: Granite hi-fi speaker stand
Inventor: BECKWITH CARL
IPC: H04R1/02
Filed: 2009-12-04
Abstract: A hi-fi speaker stand made of granite encircles or embraces an electrostatic loudspeaker panel, achieving a rigid platform for the speaker. Also, the stand design elevates the speaker system for good sound projection. The design has the benefit of considerable weight and high mass. Without such considerations, acoustic energy is lost, caused by counter-movements from the speaker system housing; weakening sound properties in all areas. The design secures the frame of the speaker with six woodscrews that locate through two 30mm thick granite sides and enter the speaker's wooden carcass frame sides where the teak trims would normally be in place. The speaker's three teak legs are also unscrewed. A platform within the stand design takes the speakers' weight. Reinforcement sections are incorporated for added strength.

Abstract: 1,131,435. Silarylene-silanols and -siloxanols. WACKER CHEMIE G.m.b.H. 8 March, 1966 [8 March, 1965], No. 10073/66. Headings C3S and C3T. Silarylene-silanols -and -siloxanols are made by reacting a polysilarylene-siloxane with at least 1 mole of an alkali metal hydroxide per mole of polymer and converting the alkali metal salt so obtained into the corresponding silarylenesilanol and/or polysilarylenesiloxanol by reaction with an acid having a dissociation constant of at least 4 Î 10<SP>-7</SP> in aqueous 0À1N solution at 25‹ C. In the process the silarylenesiloxanes are split, with breaking of the siloxane bonds, into smaller molecules having terminal Si-bonded-OH groups. The initial polymer can be used in the liquid (solution or melt) or solid (powdered) state, and the reaction thereof with the alkali is preferably effected at 15‹ to 50‹ C. Acids specified are HCl, H 2 SO 4 , H 3 PO4, H 2 CO 3  and CH 3 .COOH. In a typical Example (1) a polysilarylenesiloxane, obtained by the process of Specification 1,131,434, was melted and the melt dispersed in aqueous NaOH to yield an emulsion which was then poured into aqueous HCl with rapid stirring. The product which separated out on the surface was dissolved in ether, purified and dried to yield a wax having the formula in which z had an average value of 2À8. Uses: the products (finely divided solids or waxy soft masses) can be condensed with organopolysiloxanes to yield copolymers convertible to elastomers or moulding powders.

Abstract: 911,454. Automatic control of mills. INSTITUT FURWARMETECHNIK UND AUTOMATISIERUNG DER SILIKALHUTTENINDUSTRIE W.T.I. March 22, 1960, No. 10190/60. Class 38 (4). The grinding noise of mill 7 is picked up by microphone 1 and passed to amplifier 2, the noise of the mill being measured both in terms of frequency and amplitude. The output voltage of the amplifier is transmitted through rectifier 3 to regulator 4 for controlling the supply of grist to the mill. The characteristic of the amplifier is such that the variation of its output voltage corresponds, after rectification, to the sum of the frequency and amplitude variations of the noise. The desired characteristic is obtained through resistance-capacitance, resistance-inductance elements, or through oscillator circuits, and these elements may be used to suppress irrelevant ranges of the noise-frequency spectrum. Non-linear resistors or non-linear valves in the amplifier may be used to suppress irrelevant ranges of amplitude of the noise signal.

Title: Improved means for taking up slack in conductors supplying electric current to movable parts of machinery
IPC: H02G11/02
Filed: 1941-08-13
Abstract: 549,180. Tautening electric cables. DORMAN, LONG & CO., Ltd., and JUDGE, E. T. Aug. 13, 1941, No. 10299. [Class 78 (ii)] A device for taking up slack in conductors supplying current to moving machines, such as the trolley of an overhead travelling crane, comprises an inclined track 4 up and down which rides a wheeled carriage 8 on which is mounted a series of coaxial loose pulleys 12. The conductor 38 passes through a flared opening 35 in a contact box 34 mounted on the trolley 3, over a stationary pulley 28 down to the first of a series of loose pulleys 16 corresponding to the pulleys 12 but mounted on a fixed shaft 19. The conductor is reeved back and forth over the two sets of pulleys 12, 16 and its end is attached to a contact 39 from which leads a main 40. Close up to and in line with the pulley 28 is another stationary pulley 31, and as the trolley 3 travels from left to right the carriage 8 moves down the incline 4 till the trolley brings the opening 35 over the gap between the pulleys 28, 31, when the conductor 38 becomes transferred to the pulley 31 and the carriage 8 begins again to climb the slope 4. The pulleys may be grooved to accommodate two or more conductors, and a similar oppositely disposed incline 5 with parts duplicating those of incline 4 together with pulleys arranged co-axially with 28 and 31, may be provided for a second conductor or set of conductors 37. The pulley shaft on the carriages 8, 9 may be inclined to permit the conductor to pay on and off the stationary upper pulleys 16, 24 with minimum grind, and the slope of the inclines 4, 5 should be as low as effective gravitational pull of the carriages allows.

Title: Improvements in or relating to Circuit Arrangements for Identifying Feeder Lines in Telecommunications Exchange Systems
IPC: H04M15/08
Filed: 1968-03-04
Abstract: 1,198,921. Automatic exchange systems. SIEMENS A.G. 4 March, 1968 [2 March, 1967], No. 10313/68. Heading H4K. An electronic line finder comprises a closed ring of gates into which a hunting potential is injected when a demand potential appears on one of the lines associated respectively with the gates, coincidence of the demand and hunting potentials at one of the gates causing hunting to stop and marking of a bi-stable circuit associated with the gate to be effected. The finder is of particular use in a code-multiple telegraph exchange where it is necessary to connect lines to trunks at high speed with little probability of incorrect connections arising from the occurrence of simultaneous demands. Methods of ensuring that only one demand at a time is met include:-interconnecting the output bi-stable circuits by gates so that at the end of a finding action only that bi-stable of lowest order remains set (Fig. 2, not shown); interconnecting the ring of gates to the output bi-stables by additional bi-stables so that if the hunting potential manages to get through one of the gates even though it should be inhibited due to the presence of a demand potential thereat, the further bi-stable will lock-out the output bistable (Fig. 3, not shown); and locking-out further demand potentials until the current one has been processed. The necessary logic, for interconnecting line finders operating on a coordinate basis, viz, when more than 10 subscribers are involved and a minor modification involving the connection of the last gate in a lower order ring to the first gate in a higher order ring rather than to its own first gate, is described with reference to Figs. 4-6 (not shown). Operation, Fig. 1.-It is assumed that output bi-stable Al is set, i.e. its output is on #a1 and that a demand potential appears on e3. A central control detects, by means not shown, the presence of the demand potential and applies a "call-up" pulse to bi-stable Z1. The "set" output of the latter then causes a pulse, of length equivalent to the transit time through the ring of gates D4-B1, to be supplied from logic F, T1, T2 to each of the gates E1-E4, gate M being opened by the demand potential so as to permit logic F to operate. Consequently E1 conducts (both inputs marked) and injects a hunting potential into the ring of gates D4-B1. This potential is stopped at B3 due to the presence at the second (left-hand) input thereof of the demand potential e3. Simultaneously gate C3 opens in order to set A3 and to reset Z1. (Al was reset by the opening of gate E1). The identity of A3 and hence of the calling subscriber can be transmitted to central control using a 1-out-of-n to binary code converter (not shown). In addition the setting of A3 is used to inhibit the demand potential on e3. NOR logic is used throughout.
