IPC: E05B17/14
Filed: 1923-12-28
Abstract: 214,181. Poulsson, T. H. Dec. 28, 1923. Keyholes, obstructing; sliding bolts.-The key-- hole 5 on a safe or other door is blocked by a similarly shaped projection 12, Fig. 3, on a rocking and sliding bar 6 held in engagement by a lever 14 passing through a socket in a guide 7. Opening of the keyhole is effected by rotating a disc 18 in the direction of the arrow 35 bv means of a handle on the door which first releases the lever 14 and then rocks the bar 6 away from the keyhole by engagement of an arm 32 with a wedgeshaped member 33 on the bar, and further rota-- tion causes a projection 29 on the disc to engage a projection 30 on the bar and so slide it back. The disc 18 is locked against rotation by inserting a pin 34 at an obscure part of the door into a bar 25, teeth 24 on which engage teeth 23 on the disc. A projection 27 on the bar 25 engages a notch on the main bolt 1 to act as a further locking means. The main bolt may be withdrawn after the key is operated to withdraw the bolt 4 by teeth 21 on the disc 18 engaging teeth 22 on the main bolt. Rotation of the handle in theopposite direction causes the parts to resume the position shown in Fig. 1. Instead of the pin 34 a separate lock may be used for the bar 25 or the bar 6, which lock may be operated hydraulically, pneumatically or electrically.

Title: Improvements in or relating to tunable discriminator circuits
Inventor: BRABHAM HUGH BASIL SCHOFIELD
IPC: H03L7/20
Filed: 1957-10-21
Abstract: 863,585. Frequency discriminators. GENERAL ELECTRIC CO. Ltd. Oct. 16, 1958 [Oct. 21, 1957], No. 32787/57. Class 40(5) A tunable discriminator circuit comprising means for deriving a pair of signals having the same frequency and having respective phases which differ by the algebraic sum of a first amount which is dependent on the frequency of an input signal applied to the circuit and a second amount which is variable but is substantially independent of the frequency of an input signal, and means for deriving an output voltage whose magnitude is dependent on the overall phase difference between said pair of signals. In the embodiment shown, Fig. 2, a delay line 10 provides the first amount of phase shift referred to dependent on frequency. The second amount independent of frequency is provided by a three branch circuit 13, 14, 15, 16 and 18, 22 which gives two outputs in phase quadrature whatever the frequency through amplifiers 20, 21 and is designed so that its impedance is independent of frequency (see Specification 863,586). The two outputs are fed to the ends of the primaries of transformers 26, 27 having secondaries earthed at their centres and their ends connected to stator plates 33 ... 36 of a variable condenser 32 so providing signals of equal amplitude but progressively displaced by 90 degrees in phase thereon. The rotor plate 37 is rotatable by shaft 38 and the output signal from the rotor is constant in amplitude irrespective of frequency its phase corresponding to the angular displacement between rotor and stator, the arrangement being such that when the reading on a dial connected to shaft 38 is zero, the phase of the output is 90 degrees in advance of the output from cable 10, and as the dial reading increases the phase of the output from 37 increases with respect to that from the output of cable 10. The output from 37 forms the first signal and is compared with the second signal taken over a second path direct from one input of delay cable 10 to a quadrature phase detector including a double diode 45 producing an output dependent on the phase difference between the two signals. The delay cable 10 may be replaced by a number of band pass filter sections. A discriminator according to the invention may be used in an A.F.C. system for an oscillator, when the tuning shaft of the oscillator and the shaft 38 are ganged together and the reading on the discriminator dial will give the k.c. readings. Examples of tuning of an oscillator in which such an A.F.C. system is used are given in the Specification.

Abstract: 1472728 Knitting MACCHINE TESSILI CIRCOLARI MATEC SpA 8 Aug 1975 [27 Aug 1974] 33110/75 Heading D1K In knitting tights on a circular machine, a) a first tubular portion (leg) 11 is formed by continuous rotary knitting, b) needles along a first arc corresponding to edge 13 are raised to an inactive position while holding their loops, c) a trapezium-shaped flap 21 is formed by reciprocatory knitting on the remaining arc of needles while edge needles are progressively put out of action, holding their loops to form sides 23, 25, d) the top edge 27 of the flap is pressed off its needles, e) the latter needles then knit the top edge 40 of a new flap 41 which is formed by reciprocatory knitting, the edge needles being progressively restored to action thereby linking the sides of the two flaps, f) on completion of flap 41 the needles holding edge 13 are restored to action and all needles form the other leg 46 by continuous rotary knitting. The top edges of flaps 21, 41 may be formed as anti-ravel tabs or as turned welts. The rate at which needles are put out of/into action at the sides of the flaps is suitably only one needle for several e.g. six or eight courses, may vary as each flap is knitted-preferably increasing in two stages towards the top edge-for extra strength, and may be different at the front and rear of the tights. During knitting of the first flap individual needles at the edges may be reinserted into operation subsequent to their normal exclusion for one or more courses prior to the exclusion of the next needle, to give a better junction between the flaps. Similarly, when knitting the second flap needles may be temporarily reinserted into action prior to their permanent reinsertion.

Title: Process for the preparation of terephthalic acid
IPC: C07C51/265
Filed: 1953-08-14
Abstract: Terephthalic acid is prepared by catalytic oxidation of para-di-isopropylbenzene with gaseous oxygen in the presence of an inert solvent and an oxygen-containing compound of a heavy metal as catalyst.  The solvent may be an aliphatic or araliphatic acid containing 2 to 8 carbon atoms per molecule, such as acetic, propionic, butyric, pentanoic, isobutyric, phenyl acetic or beta-ethoxyacetic acid.  The solution may contain from 10 to 90 per cent by weight of solvent, preferably 12 to 40 per cent. Suitable catalysts are the oxides, hydroxides, organic salts or combinations thereof of lead, manganese, iron, nickel, cobalt, chromium, vanadium, copper or mercury.  The organic salts may be of one or more of the acids formed in the reaction system or of acids e.g. acetic and other acids having 2-8 carbon atoms per molecule, and naphthenic acids.  An organic peroxide, or a peroxide-forming material, such as benzoyl peroxide, perbenzoic acid, peracetic acid, acetaldehyde and similar aldehydes of 3 to 5 carbon atoms per molecule, acetone and ketones having 4 to 6 carbon atoms per molecule, di-ethyl and similar ethers containing 5 to 10 carbon atoms per molecule, hexene, cyclohexene and olefines containing 7 to 12 carbon atoms in the molecule, or inorganic peroxides may be present in a concentration in the range of about 0.05 to 25 per cent based on the weight of p-di-isopropylbenzene.  In an example, the p-di-isopropyl benzene, a solvent such as acetic acid, and manganese terephthalate, acetate or lineoleate, are fed into an oxidizer and air is passed through the agitated mixture.  The resulting product is a solid and is separated, e.g. by filtration, and the filtrate is recycled to the oxidizer. The crude acid is washed and dried.  The process may be operated continuously and run in conjunction with the preparation of p-di-isopropylbenzene as described in Specification 762,763.  A flow plan of a suitable continuous process is illustrated.  The pure terephthalic acid may be converted into its dimethyl ester by reacting with methanol in the presence of sulphuric or hydrochloric acid.  The dimethyl terephthalate may be reacted with a glycol containing 2 to 6 carbon atoms giving a polymeric ester.

Patent GB-332700-A (GB)
IPC: C06F1/20
Abstract: 332,700. Newman, J. G. June 17, 1929. Matches.-Matches are made from strips of paper pulp board by passing the strip through splitting-rollers to produce tongues projecting from a stub and then through shaping, dipping, perforating, heading and staggering devices. The splitting-rollers 24, 25 are formed with rectangular teeth 26, Fig. 3, separated by blocks 27 of rubber faced with metal plates 28. The split strip next enters between shaping-rollers 39, 40 having co-operating ribs 45 and slots 43, Fig. 5. and also removable bosses 44 and holes 42. The ribs and slots serve to form a rib along the length of the tongue to reinforce it and the bosses and holes shape the head as shown in Fig. 11. The strip next passes through a paraffin bath 46, a roller 51 bearing on the tongues to cause them to dip into the liquid, and then between a perforating roller 52 and co-operating grooved roller 53 so as to receive a row of perforations along the base of the tongues. Feeding rollers 67, 68 now pass the strip to a heading-block 59 where igniting-material from a vessel 62 is fed through a channel 65, Fig. 9, to a recess through which the head of the tongue travels. A spring-pressed plate 66 seals the recess. Finally the strip passes between rollers 70, 71 of which the upper has pins for bending alternate tongues. The bosses 44 on roller 40 may be removed if matches shaped as shown in Fig. 12 are desired. The rollers 51, 52 and 70 may also be displaced to render the dipping, perforating, and staggering devices ineffective.
