Title: Improvements in or relating to machine presses
IPC: B21D5/02
Filed: 1958-02-18
Abstract: 866,989. Angular bending ; shearing. CHARLES, S. W., GRIGG Ltd., and STEVENS, A. T. W. Feb. 18, 1959 [Feb. 18, 1958], No. 5303/58. Class 83 (4). A press brake or guillotine shear having a beam moved to and from a bed by two main fluid-pressure cylinders, one at or near each end of the beam and valve means for controlling fluid supply to the pressure cylinders is characterized in that the valve means is controlled by transmission members, e.g. chains, connected one to each end of the beam, so that the ends of the beam have equal movement. A beam 2 formed with a longitudinal bending edge 6 is moved down towards a bed 1 formed with a longitudinal groove 5 to bend sheet-metal between the edge and the groove, by hydraulic cylinders 8 disposed one at each end of the beam 2. To ensure that ends of the beam 2 are moved equal amounts, valve means 9 controlling fluid flow to the cylinders 8 is in turn controlled as follows : A chain 13 is adjustably secured at one end at 26 to one end of the beam 2 and passes over a sprocket 47 on a press frame member 3a, and over a pinion 43, formed on a wheel 15, to a compressed air cylinder 18. Another chain 14 secured to the other end of the beam 2 and to cylinder means 18, at the same pressure as the other cylinder 18, likewise passes over pinions 42, 44 formed on the wheel 15, the chain 14 dividing into two parallel runs at this point. The wheel 15 is loose on a shaft 19 mounted on a carriage 16 slidable in guides 17 in the press frame 3a. If the ends of the beam 2 move equally the wheel 15 merely rotates on the shaft 19 but if one end should move more than the other the carriage 16 moves to rock, through links 20, bell-cranks 21 to actuate the valve associated with the appropriate cylinder 8. Arms 27 on the shaft 19 operate switches 30 to stop the machine on excessive unequal movement of the beam ends. The beam 2 may be set at an angle to the bed 1. In a modification, Fig. 8, the shaft 19 is carried by a pivoted lever 72, the upper end of which engages a roller 78 on the bell-crank 21 to actuate the valve means 9. Alternatively, Fig. 10 (not shown), the lever 72 may be connected by a link to the bell-crank 21. The stoparms 27 are carried by the pivoted lever. Straight parts of the chains 13, 14 may be replaced by rods. Only one chain may be adjustable on the beam 2. Each chain may be connected to the wheel 15 by a pin and the part of the chain extending from the cylinder 18 connected to the wheel 15 by a diametricallyopposite pin. The machine may be arranged so that the beam moves horizontally or at an angle instead of vertically.

Title: Improvements in theodolites and in other angle measuring instruments
IPC: G01C1/02
Filed: 1927-02-26
Abstract: 288,416. Baker, T. Y., and Cheshire, R. W. Feb. 26, 1927. Theodolites.-In a theodolite &c. in which the graduations at two different points of a circle are optically projected into juxtaposition in the field of view of a single eyepiece, the graduations are projected into two different parts of the field of view with a datum mark between the adjacent ends of the two images, and a fine reading device is provided for displacing the images simultaneously with respect to the datum mark and in the same direction as seen in the field of view. Fig. 1 shows the general arrangement of the instrument and Fig. 2 the optical elements for projecting the graduations of the vertical circle. The horizontal trunnion A of the telescope B is mounted in standards C and carries the vertical graduated glass circle D. The trunnion is surrounded by a casing E which is prevented from rotating by a key F. Light entering this casing through an aperture G is reflected in opposite directions by prisms H and passes through condensers J to the reflecting surfaces k<1> of prisms K which turn the rays through less than a right angle and direct them towards the surfaces k<2> of the prisms from which they are reflected through apertures k<3> on to the circle D, the apertures being at opposite ends of a diameter of the circle. After reflection by the circle the rays re-enter the prisms K and are reflected by the surfaces k<2>, k<4> so as to pass through objectives L and to be received by prisms M which direct the rays towards deviating devices N in the form of parallel glass plates. The rays after passing through the plates N are received by prisms O, the reflecting surfaces o<1>, o<2> of which direct them into juxtaposition in the field of view of an eyepiece P. A glass plate R carrying the reading mark S is cemented to the prisms O. For displacing the images across the field of view of the eyepiece the plates N are adapted to be turned about an axis n<1> by a head T which is geared to a rotatable glass disc U carrying a cam w<2> bearing on a plunger V terminating in a cross-head v<2> in which are slots engaging eccentric pins attached to spindles n<2> and so arranged that movement of the plunger causes the plates N to rotate in opposite directions. Graduations around the disc U are visible in the field of view of the eyepiece. The arrangement for projecting the graduations of the horizontal circle is substantially similar to that above described, but additional image-forming elements F<1>, G<1> may be provided to project the images into an eyepiece P<1> opposite the eyepiece P. Fig. 8 shows the field of the eyepiece, with the scale images W on each side of the datum mark S. To take a reading the head T is turned until the two division marks adjacent the mark S (in the Figure the graduations 80‹ 20<1> and 260‹ 20<1>) are equally spaced therefrom. The upper image then shows that the movement of the plates N corresponds to a reading of 10<1> so that the full reading is 80‹ 30'.

Inverting and transposing frequencies of telephone currents.-Secrecy is secured in radio and like signalling systems by transmitting a signal (e.g. a voice current) in short sections. the component frequencies being in the correct order and in inverse order in alternate sections. As shown in Fig. 2, a signal prcducer S such as a microphone is connected through two channels A, B to the signal transmitter L, one channel including a modulator M and filter F. A local alternating source G is connected to, the modulator, and the lower side band (in which the component frequencies are inverted in position in the frequency spectrum) is selected by the filter. A switch U alternately connects the two channels to the transmitter .L. At the receiving end, Fig. 3, the signal receiver L is connected through a commutating switch U to two similar channels which re-combine m the receiving instrument E. The switch movements are maintained in step by special impulses sent over a separate system, or by the, use of synchronized motors. The synchronizing impulses necessary in picture-transmission may also be used forsynchronizing the switches. The switches may be operated at irregular intervals by means of synchronized drums, each drum having a series of contact strips of different lengths.

Patent GB-717232-A (GB)
Title: Improvements in or relating to fluorinated amines
Filed: 1951-03-08
Abstract: The invention comprises 1,1 - dihydro - perfluoroalkylamines of the formula CnF2n+1CH2NH2 where n is an integer from 3 to 17, their salts and their N-substituted amide derivatives of the formula RCONHCH2CnF2n+1, where RCO is an acyl radical of a monocarboxylic acid.  The amines are prepared by reducing a perfluorocarboxamide of the general formula CnF2n+1CONH2 in dry ether solution under an inert atmosphere with lithium aluminium hydride.  The fluorocarbon amides can be prepared by reacting the corresponding fluorocarbon acid fluorides or alkyl esters with ammonia.  The fluorocarbon acid fluorides, having the formula CnF2n+1COF can be prepared by electrolysis of a solution of anhydrous liquid hydrogen fluoride containing in solution the corresponding hydrocarbon carboxylic acid of formula CnH2n+1COOH or its anhydride at a cell voltage insufficient under the conditions of reaction to generate free fluorine.  The amines may be isolated as their insoluble sulphates or hydrochlorides from which the free amine is liberated by treatment with caustic alkali.  Water may be removed by distillation from freshly calcined calcium oxide.  In examples: (1) 1,1-dihydroheptafluorobutylamine is prepared by the reduction with lithium aluminium hydride of heptafluorobutyramide in ether. The product is isolated as its bi-sulphate, and the free base is liberated by adding alkali to the dried salt followed by distillation.  From the mother liquors from the amine bisulphate there may be isolated heptafluorobutyric acid, and heptafluorobutyraldehyde hydrate (C3F7CH (OH)2) which may be converted into the aldehyde C3F7CHO by dehydration. Dihydropentafluoropropylamine is prepared similarly, but is isolated as its hydrochloride, the aldehyde hydrate by-product being first removed by extraction with ether of the sulphuric acid solution of the amine. 1,1-Dihydrotrifluoroethylamine is prepared similarly, preferably in a tetrahydrofuran reaction mixture.  (2) 1,1-Dihydrononadecafluorodecylamine is prepared similarly by reduction of n-nonadecafluorocapric amide.  Physical constants of compounds CnF2n+1CH2NH2, in which n is 3 to 1 (inclusive) are given. The products of the invention can be diazotized and the resulting diazo compounds purified by distillation.  With acids stronger than acetic acid, e.g. with fluorocarbon carboxylic acids, the amines form salts.  Reaction of the amines with carboxylic acid anhydrides yields amides of the formula R.CONH.CH2CnF2n+1, where R.CO is the acyl radical corresponding to the anhydride, such as C3F7CONHCH2C3F7 by reaction with heptafluorobutyric anhydride, and CH3CONHCH2 C3F7 by reaction with acetic anhydride, of the corresponding fluorocarbon amine.  The hydrochloride p  C3F7CH2NH2.HCl, and the amine C9F19CH2NH2 and its hydrochloride can be sublimed.  Specifications 670,991, 676,273 and U.S.A. Specification 2,348,321 are referred to.
