Abstract: 1,047,635. Dispensing food. REJLERS INGENJORSBYRA A.B. July 8, 1963, No. 26946/63. Heading A4T. [Also in Division B8] In a pneumatic dispatch system for distributing packages of different foodstuffs &c. from a series of storage containers 1, 2, Fig. 2 to various receiving stations 12 in a building, factory, &c. to conveyer routes 3, 4, 6 &c. which may be in part shutes or endless conveyers are arranged so that the foodstuffs requiring heating or thawing &c. are diverted in route 3 through ovens 5 while the cold foodstuffs pass directly through an unheated route 4. The demand for hot or cold foods may be signalled from each station 12, and punched cards or other delayed signal recording systems used to control release of the packages. The ovens 5 may be set to different temperatures or to different speeds of conveyance for varying the degree of heating, and may be set automatically by photo-electric or other scanning of optical, magnetic &c. information on the various packages. Multiple passages 3a, b, c may be arranged through the ovens 5 so that different degrees of heat may be applied to different food-stuffs. Automatic diverters 18 may be arranged at each oven so that foodstuffs may pass from overloaded passages to alternative passages. Puncher card stores 14, 15 may be arranged to record deliveries and operate through a retaining mechanism 17 to prevent the despatch until the previous order has been completed. A pneumatic tube despatch system is necessary for carrying the packages to the final destination in minimum time with a minimum loss of heat. Suitable disposable packages for delivery of foodstuffs are described in Specification 1,047,634.

Title: Improved hot gas reciprocating engine
IPC: F02G1/043
Filed: 1953-10-02
Abstract: 772,753. Hot gas engines. SCHIEL, L. R. Oct. 2, 1953 [Oct. 3, 1952], No. 27131/53. Class 7 (1). The engine comprises a plurality of cooled contraction cylinders and heated working cylinders arranged in coacting pairs opposed to each other and so located that the movement of their pistons takes place parallel to a mainshaft to which is attached a camplate which transmits the power to the main shaft. Fig. 5 is a diagrammatic view of a four cycle hot gas engine in which the pistons cooperate with a rotary cam plate 8. The hot cylinders 1-1c are immersed in molten lead. Each communicates through a corresponding heater 13 regenerator 12 and cooler 11 with one of the cold cylinders 2-2c. In order to produce isothermal heating the bottom of the cylinders 1 may be arranged as shown in Fig. 8 in which hot lead is introduced through a pipe 24 and led away through a pipe 25. Alternatively water may used. The piston may comprise projections 21, Fig. 9. Fig. 10 is a plan and shows the location of the heaters 13. Each pair of piston rods comprises a cooperating tongue 15 and groove 14, Fig. 6. Rollers 7,16 cooperate with the cam 8. Ball bearings may be provided for the rollers and for the support of the piston rods. A furnace employing either solid or liquid fuel may be used to heat a filling medium for example lead or Wood's metal which rises when heated and heats the preheaters and heating cylinders. Air for combustion passes through a preheater and cooled gases flow back into atmosphere from the preheater. The cold cylinders may be located in a water bath a cooler being provided for cooling the water therein. In a modification liquid lead may be injected into the hot cylinder and cold water into the cold cylinder. It is stated that the projections on the piston may dip into liquid in the bottom of the cylinder. The working medium may be air nitrogen or preferably argon. The volume of the hot cylinders may be 3-4 times that of the cold cylinders. The engine is controlled by regulation of the fuel supply and by regulation of the charge. A high pressure container can be connected by means of valves (not shown) in pipe 9 either with the machinery housing or with the pressure container. By this means both precompression and power can be regulated. It cannot be avoided that some highly compressed gas enters the machinery housing due to lack of tightness in the piston rings but this gas is forced back into the pressure vessel through a very small compressor and from there returned to the cylinder as required. The cam plate may be designed so that four reciprocations of the pistons will occur for one revolution of the engine shaft. All the cylinders may be placed on the same side of the cam plate if for example the cold cylinders are arranged in an inner circle and the hot cylinders in an outer circle. Lubrication can be effected by injection from the crank case.

Title: Phenolphthalein monophosphate salts and intermediates therefor and process for their preparation
IPC: C09B11/08
Filed: 1965-06-25
Abstract: The invention comprises phenolphthalein monophosphate salts of the formula <FORM:1070121/C2/1> wherein the total charges on the phenolphthalein monophosphate moiety and the cations are equal but of opposite sign and wherein the cation is ammonium, substituted ammonium, sodium, potassium or calcium.  The salts are prepared by reacting phenolphthalein monophosphoric acid of the formula <FORM:1070121/C2/2> with ammonia or an amine (e.g. cyclohexylamine, ethanolamine or tetramethylethylenediamine) or with a basic salt of sodium, potassium or calcium.  The phenolphthalein monophosphoric acid may be prepared by reacting a mixture of phenolphthalein and a metal halide salt with a phosphorus oxyhalide, e.g. phosphorus oxychloride, to give a phenolphthalein oxyphosphoryl dihalide having the formula <FORM:1070121/C2/3> and then hydrolysing this with ice-water to give the corresponding phenolphthalein diphosphoric acid in the quinoid form of the formula <FORM:1070121/C2/4> which is converted to the monophosphroic acid derivative (II) above by refluxing in an acidic medium or by saponification followed by acidification.  The invention also comprises products of Formulae (III) and (IV) above as new compounds.  The compounds of Formula (I) are useful as substrates for the determination of phosphatase enzymes, e.g. in the determination of alkaline and acid phosphatases in blood serum and other biological materials.

Title: Improvements in or relating to ultra-high frequency electrical apparatus
IPC: H01P5/04
Filed: 1945-10-22
Abstract: 604,231. Automatic control systems. GARFITT, R. G. Oct. 22, 1945, No. 27745. [Class 38 (iv)] [Also in Group XL (c)] An arrangement for controlling the flow of electromagnetic energy in a wave-guide comprises a coil of conducting material free to rotate within the guide about an axis perpendicular to the axis of the coil, the coil being so shaped and dimensioned that it forms an obstacle resonant to the energy passing through the guide. Means are provided for urging the coil towards a predetermined position, and means for producing a magnetic field surrounding the coil, so that by the application of a direct current to the coil winding, the resonant obstacle formed thereby may be rotated to vary the flow of energy through the guide. Figs. 1. and 2 show a transverse and longitudinalsection through a wave-guide 10 in which energy flows from a to b. A coil 11 pivoted at 12 and controlled by hairsprings 13 is dimensioned as described in Specification 597,216, [Group XL], so as to be a resonant obstacle to the transmitted energy when the plane of the coil is transverse to the guide. A magnet 14 provides a magnetic field so that when a current is supplied to the coil 11 it sets in a direction determined by the value of the current and so determines the flow of energy in the guide. Where the current is derived from a controllable D.C. source 15, the arrangement may be used as a remote-controlled power regulator. In Figs. 1 and 2, part of the current is provided by a rectifier 17 which rectifies energy abstracted by probe 18 from the guide at a point beyond the coil 11, and this current opposes a steady current from source 15. The coil 11 then moves so as to keep the energy flow constant. In a similar way, the arrangement may be used to keep the output of a crystal mixer constant by varying the flow of energy from a local oscillator in dependence on the output of the mixer, Fig. 3, (not shown). Fig. 4 shows a D.C. amplifier comprising a wave-guide 10a fed with energy at a, leading to a loop 10b, 10c, including a probe 18a positioned so that paths 10b, 10c differ by half a wavelength. Thus with a resonant coil 11a arranged so as not to obstruct the guide, there is no output at 18a. 'If a small direct current is fed to coil 11a so that it moves to obstruct one or other of paths 10b, 10c, an output appears at 18a which can be rectified to give a larger direct current.
