Patent GB-137339-A (GB)
Title: A new or improved process for producing caramel
IPC: C12C5/04
Filed: 1917-11-13
Abstract: 137,339. Daniel, A. Nov. 13, 1917. Caramel is obtained by heating carbohydrates, such as starch potato syrup, grape, beetroot, fruit, or milk-sugar, or molasses or treacle with acetic acid while adding dehydrating-agents, such as acetic anhydride, sodium acetate, hydroxide or carbonate, or mineral acids, or with sodium acetate alone. The process may be carried out either in an open vesel with or without a reflux cooler, or in a closed vessel under pressure. In an example, 100 kilos of beet-root sugar are dissolved in a solution of 10 kilos of acetic acid and 10 kilos of sodium acetate in an enamelled iron vessel provided with a reflux cooler, and the solution boiled for 6-8 hours. The caramel produced is precipitated by sodium carbonate or hydrate. By using a double quantity of acetic acid, the tinctorial power of the caramel is nearly doubled. In some cases, acetic acid may be used alone. In another example, 100 kilos of beet-root sugar are melted in an iron vessel, and 10 to 20 kilos of sodium acetate added while intermixing the mass. The caramel obtained is easily soluble in water and alcohol, and colours rum, brandy, and liquors without distilling taking place.

Abstract: 236,049. Kasantzeff, F. July 15, 1924. Drawings to Specification. Fluid-pressure. - In compressed-air brakes of the type using two train pipes, the valve supplying air from the main reservoir to the feed pipe which supplies the auxiliary reservoir is arranged, when the driver effects a reduction of pressure in the main pipe, to increase the pressure in the feed pipe, so that the brakes are applied rapidly and with increased power; whilst release is assisted, on restoring the pressure in the main pipe, by equalizing the pressure in the feed pipe and auxiliary reservoirs with the pressure in the main pipe through the distributors, which are of special construction. The detailed description and drawings of this Specification and of Specification 236,048 are the same, but the claims in the present case relate to a special form of driver's valve used with this system, which is also applicable to compressed-air brakes generally.
Patent GB-566345-A (GB)
Title: Improvements in or relating to apparatus for indicating the end of a predetermined time period
IPC: G04F3/02
Filed: 1942-11-30
Abstract: 566,345. Time-alarm signals. TELEPHONE MANUFACTURING CO., Ltd., SMITH, S. J., and TERRY, R. ST. G. Nov. 30, 1942, No. 17020. [Class 118 (ii)] [Also in Group XXXVII] Apparatus for indicating the end of e predetermined time period comprises a pointer which is rotat able by a spring, means operated by electric impulses to allow rota tion of the pointer, and an electric switch thai is operated to complete an alarm or other circuit when the pointer has passed through a predetermined angle In the constructior shown in Figs. 2 and 5 the pointer Q can be rotated by a knob E to set it to the indica tion of a desired time period. A spring is stressed as the pointer is moved away from zero, and tends to return the pointer to zero as soon as the knob is released. The return movement is regulated by an escapement or oscillating pallet L which co-operates with two interengaging gear-wheels, as described in Specification 362,518, [Group XVIII]. Normally, the pallet is kept in contact with the wheel F by means of a spring M, but is oscillated from one wheel to the other when an electromagnet O is energized by electric impulses from a central clock system. The oscillations permit the wheels E, F and the pointer Q to move step-by-step under the influence of a spring. When the moving pointer reaches the zero position, a pin P secured to the pointer engages and closes a switch A, Fig. 8, which operates an alarm, or starts or ends an operation or process. Continued movement of the pointer releases the alarm switch A and opens a switch C that controls the circuit of the electromagnet O, and both circuits are thus de-energized until the pointer is again set to time a given period. The actual starting of the mechanism after the setting of the pointer is effected by closing a master switch in the circuit of the magnet coil O. In a modification, a second slow-running pointer is included and is driven by the pointer Q as in a clock. When the second pointer approaches zero, it moves the switches A, C into the path of the pin P, the switches normally being held clear of the pin by a spring. In another arrangement, the arrival of the pointer at its zero position causes the operation of ratchet-and-pawl resetting means after which a new period is timed and so on.

Title: Improvements in or relating to travelling wave magnetron tubes
IPC: H01J25/42
Filed: 1952-07-07
Abstract: 712,565. Travelling-wave tubes; magnetrons. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 7, 1952 [July 30, 1951], No. 17079/52. Class 39(1) In a travelling-wave tube in which an electromagnetic wave injected into a delay line is amplified by interaction with an electron beam moving parallel to the line and perpendicularly to crossed electric and magnetic fields, at a velocity equal to the ratio of these two fields and to the phase velocity of the wave, the delay line is divided into two sections each co-operating with an opposing electrode to form two interaction spaces providing contrary energy exchange mechanisms; the first space provides strong focusing of the electrons and the second amplification of the wave. The first delay line section 9, Fig. 4, is at a negative potential and is in alignment with the negative electrode 6 of the second interaction space. It is opposed by a positive electrode 8 in alignment with the second delay line section 10. This section 10 is at a positive potential and is situated opposite the negative electrode 6. As shown in Fig. 4, the positive electrode 8 forms an attenuating section for the second delay line section 10. The first interaction space is relatively short; so as not to excite a predominating electron de-focusing wave. By using for the focusing section 9 a delay line propagating a wave in the opposite direction to the beam such as a symmetrical interdigitated line or a zig-zag line. an artificial attenuating section need not be provided. The tube of Fig. 5 is arranged to function as a self-oscillator controlled by the wave introduced at 4 by providing an interdigitated or zig-zag line for the amplifier section 10, with the provision of an attenuating section 8 at the end of section 10 adjacent the collector 7, and with the output derived at the opposite end 5. Either tube may'be designed to function as a frequency multiplier by making the beam velocity in the first interaction space equal to the phase velocity of the fundamental wave on section 9, and equal to the phase velocity of the desired harmonic wave on section 10.

Filed: 1950-07-07
Abstract: 685,723. Making metal fabrics. ROSS, O. Z., NORMAN, H. H., and SKLAR, H. B., (trading as ZIG ZAG SPRING CO.). July 7, 1950, No. 17058/50. Class 83 (iv). Corrugating; angular bending; shearing adjuncts.-In a machine for bending wire into sinuous form the wire is guided by pins 84, 85 on an oscillating head 67 to be bent by pins 42, 43 on an oscillating member 39 and a retaining-pin 158 movable towards and away from the bending pins and in and out of the plane of oscillation thereof in synchronism with the movement of the bending pins engages consecutively the convolutions of the wire to allow of overbending. As shown in Figs. 33, 35, 37, the pins 42, 43 overbend the convolution whilst the wire is held by the pin 158. The pin 158 is withdrawn and the movement of pins 42, 43 reversed and guide pins 84 lowered to allow the pin 42 to pass the bend. Pin 43 then contacts a bend to feed the wire forwards and pins 42, 43 make a reverse bend and retainer pin 158 is advanced to hold the wire during overbending. The bending pins 42, 43 are mounted on a member 39 on a shaft 33 with pinion 32 engaging a rack 33 on a frame 28 oscillated on rods 29, 30 by a crankslider mechanism from a shaft 10. A pinion 14 on the shaft 10 rotates a shaft 16 with crank slider mechanism 56, 58 oscillating a frame 58 on rods 60, 61. A rack 59 on the frame engages a gear 68 meshing with a similar racked frame 67 oscillated on rods 76, 77. The frame 67 carries the guide-pins 84, 85 which are oscillated in synchronism with the bending pins. Wire is bent to sinuous form by the oscillation of the bending pins and the movement of the pins 84, 85 prebends the next convolution, Fig. 33. The pinion 14 rotates a shaft 18 driving a crank 128 connected by a rod 129 to a cross-head carrying shafts 136, 137 on which a housing 150 is mounted. Rotation of the shaft 18 reciprocates the housing 150 in which the retainer pin is mounted, the pins being raised in opposition to pressure of a spring 159 by anchored pivoted rods 165 turning a shaft carrying lifting lugs. The sinuous wire is fed between a roll 272, Fig. 15, and a screw-adjusted anvil 275 to bend each convolution out of the plane of the sinuous wire. A punch is reciprocated through a onerevolution clutch to sever the wire and a V- shaped blade straightens the end of the cut wire, Fig. 16 (not shown). The machine is controlled by a lug on a chain driven from the shaft 180 closing a timing switch, Fig. 25, not shown, to cause stoppage of a feed wheel on the shaft 180 and operation of a one-revolution clutch for the shear.
