Title: Improvements in methods of and means for recording and reproducing sound
IPC: G11B3/00
Filed: 1928-10-24
Abstract: 323,833. Kennedy, R. A. Oct. 24, 1928. Sound grooves; tools, recording and reproducing.-Relates to systems for recording and reproducing sound in which, in order to record a greater quantity of matter than usual on a gramophone record, the speed of rotation of the turntable, both in recording and in reproducing, is much less than usual (say one-half to one-tenth of the ordinary speed), and the amplitudes in the sound trace are similarly reduced. According to the invention, this result is obtained without reduction of the width of the sound-groove or of the pitch of the spiral trace. The stylus is, accordingly, as broad as an ordinary stylus, but it may have a fine blade edge which in use lies transversely across the sound-groove. To obtain the reduced amplitude of vibration, the recording and reproducing diaphragms are made less flexible than those usually employed. The reduction of amplitude may be proportionately greater than the reduction in the length of the sound-trace. Valve or other amplifiers are used in conjunction with the reproducing machine. Specification 215,761 is referred to.

Title: Salts of penicillin g with amines
IPC: C07D499/00
Filed: 1957-10-02
Abstract: The invention relates to a salt of penicillin G with a compound of formula <FORM:0811834/IV (b)/1> wherein R3 and R4 are either individual ethyl groups or form together with the nitrogen group to which they are attached a morpholino ring, i.e. 1-morpholino-3,3-diphenylbutane and 1-diethylamino-3,3-diphenylbutane.  The salts are stable crystalline salts obtained by reacting acid penicillin G with the base; or a salt of penicillin G, e.g. sodium salt with a salt of the base, e.g. hydrochloride in aqueous solution.  The salts may be used to isolate penicillin from solution or may be used in animal feed supplements. The amines are produced by reacting alpha methylstyrene with formaldehyde and hydrochloric acid to produce 1-chloro-3-phenylbutene-2 which is treated with (a) diethylamine to produce 1-diethylamino-3-phenyl-butene-2; or (b) morpholine to give 1-morpholino-3-phenyl-butene-2.  These substances (a) and (b) when reacted with benzene in the presence of aluminium chloride produce 1-diethylamino-3,3-diphenylbutane and 1-morpholino-3,3-diphenyl butane respectively.

Filed: 1975-07-23
Abstract: 1512806 Locking suspension units on braking HONDA GIKEN KOGYO KK 23 July 1975 30887/75 Heading F2S [Also in Division B7] In a motor cycle having a front fork comprising a pair of telescopic shock absorbers, and a brake on the front wheel, the brake includes an element, which is angularly displaced relative to the fork when the brake is applied to actuate means arranged to resist compression of the shock absorbers by extra load transferred to the front wheel due to application of the brake. In Fig. 1 each leg of the fork 20 comprises a fork tube 22 telescopically engaged with a lower casing 21, and the mounting plate 14 of an internal expanding shoe brake is rotatably mounted on the front axle 11. Linkage 40, 41, 46 extends between the mounting plate 14 and a lower bridge member 33 connecting the tubes 22 so that torque acting on the plate 14 when the brake is applied produces an upward force on the member 33 which balances the transfer of load on to the front fork 20 resulting from the braking action. In Fig. 4, each of the shock absorbers in the front fork 20 includes first and second chambers A, C between which hydraulic fluid flows when the fork is compressed, and flow between the chambers A, C is inhibited when the brake is applied. The brake mounting plate 14 is connected by linkage 111, 114, 117 to a locking valve 105 which is normally held by a spring 109 in a position wherein the chambers A, C communicate through passages 103, 104 and a space S but closes when the brake is applied. The arrangement is such that if the forks are subjected to a shock load when the brake is applied the valve 105 is forced open by increased pressure in the chamber A so that the shock can be absorbed. A one-way valve 107 allows extension of the forks evenwhen the valve 105 is closed. In Fig. 5 (not shown) the front wheel is provided with a disc brake including a caliper which is pivotally mounted on one leg of the front fork and arranged to actuate a locking valve when the brake is applied. The locking valve may have a leak hole which permits limited communication between the chambers of the shock absorber even when the valve is closed.

Abstract: 1,075,689. Crimpable composite filaments. E. I. DU PONT DE NEMOURS & CO. July 21, 1965 [July 24, 1964], No. 31018/65. Heading B5B. A helically crimpable composite filament comprises a laterally eccentric assembly (sideby-side or eccentric sheath core) of two synthetic polymeric components one of which is a polyester partly crystalline in stable conformation that does not exceed 90% of the length of the fully extended molecular conformation of the polyester, the said polyester having a higher shrinkability at moderately elevated temperature than the other component whereby it is adapted to assume generally a position on the inside of crimp helices formed when the assembly crimps. The said polyester may be poly- (trimethylene terephthalate, poly(trimethylene dinaphthalate) or poly(trimethylene bibenzoate). The second component of the filament may have a crystalline conformation more closely approaching its fully extended molecular conformation than the first component, e.g. 95% of the length of the fully extended molecular conformation. The Specification does not contain any process claims. In an example of a preferred process for making the fibres, a poly(trimethylene terephthalate) having an intrinsic viscosity of 1À3 and a polyethylene terephthalate having a relative viscosity of 18 are cospun at 280‹ C. from a spinneret in which two melts of the polymers are brought together just behind each extrusion capillary. The resulting composite filaments are drawn to 470% of their original length at 93‹ C. and annealed at 170‹ C. for about 0À1 second or longer while held at constant length. The polyester of higher shrinkability must be non- extended to the extent that the crystalline repeat-distance is 90% or less of the fully extended chemical repeat distance. An X-ray technique is described for measuring the crystalline repeat-distance of the filament components, and a molecular model technique is described for measuring their chemical repeat distance: Both measurements are recorded in Angstrom units and the ratio A/B x 100 is described as the per cent extended.

In Fig. 1 provided that A.C. signals E1 and E2 are present a corresponding direct voltage is produced by rectification across Zener diodes 16 17. These bias collector and base of T5 into conduction to commence oscillation, and thus an AND function is performed on E1, E2. The output is amplified by T6. An OR function is achieved (Fig 2, not shown) by connecting winding 42 and the input end of R18 to a common point which is fed by a plurality of input transformer and rectifier circuits, any one of which will initiate oscillations if it receives an input E1, E2 or E3. An inverting function is achieved by connecting winding 42 to the positive supply and resistor 18 (22, Fig 3, not shown) also to the supply, so that T5 normally oscillates An input A.C. E to transformer 1 produces a negative rectified voltage on a capacitor 10 connected to winding 41 thus stopping oscillation. In a so-called storage circuit (Fig. 4, not shown) basically similar to Fig. 1 but with a feedback resistor (24) between T5 emitter and winding 41, T5 will oscillate when both inputs S and R are present and will continue oscillating after removal of R but not after removal of S. The amplified output of the blocking oscillator may be rectified and inverted (Fig. 5, not shown).
