Title: Improvements in or relating to apparatus for the freezing and delivery of portions of ice cream
IPC: A23G9/16
Filed: 1956-08-03
Abstract: 797,638. Ice-cream freezers. PARISI, R. Aug. 3, 1956 [Aug. 4, 1955], No. 23977/56. Class 29 Ice-cream mix 2 is lifted from a reservoir 1 by a dish-shaped annular cup 8 axially through a freezing cylinder 3, the cup being rotated to fling the mix against the cylinder by centrifugal force and the frozen mix being scraped off the cylinder by a disc 9 and discharged through a delivery pipe 41. As shown, the cup is carried on the lower end of a tube 7 supported by ball-bearings 11 on the bottom of a screw-threaded tube 12 working in a nut 13 carried by a fixed tube 14. The tube 12 is rotated from a driven member 22 by two rods 18, 19 which slidably engage notches in a plate 17 fixed to the top of the tube 12. Tubes 12, 7 can be coupled by clutch members 37 normally disengaged by a spring but engageable by a rod 34 within tube 12 and having an upper actuating lever 35. In operation, the driving motor is started and tube 12 rotates and rises together with tube 7, the latter not rotating because clutch 37 is disengaged and because of friction between tube 7 and its packings 38, 38a. When, however, the cup 8 has risen into the cylinder 3, lever 37 engages cam 39 and clutch 37 is engaged so that the cup is rotated until it reaches the top of cylinder 3 to throw out the mix. The scraper 9 carries the frozen mix to the top where it is diverted into delivery 41. When the device reaches the top, a clutch is thrown over to reverse the rotation of member 22 and the parts are moved to the lowest positions whereupon a switch cuts out the drive motor. In a modified form, the threaded lifting mechanism and the clutch 37 are replaced by arrangements carrying out the same functions.

Abstract: 1,242,185. Preparing (cis-1,2-epoxypropyl)- phosphonic acid and intermediates thereof. MERCK & CO. Inc. 12 May, 1969 [15 May, 1968], No. 23981/69. Heading C2C. (cis - 1,2 - Epoxypropyl)phosphonic acid or an ester or salt thereof is obtained by eliminating nitrogen from a cis azo phosphonic compound of the formula wherein each R is a hydrogen atom or a substituted or unsubstituted hydrocarbyl or heterocyclic radical, or from an organic or inorganic salt of such compound in which at least one R is a hydrogen atom. The elimination of nitrogen may be effected by irradiating a solution of the azo compound with U.V. light preferably in the presence of a photo-sensitizing agent, e.g. benzophenone or acetophenone, or by heating the azo compound, generally at above 80 C., e.g. from 100 to 300 C., the heating being carried out directly or with the azo compound suspended or dissolved in an appropriate suspending agent, e.g. a mineral oil, or inert solvent, e.g. toluene, pyridine, chloroform, cumene or xylene. Suitable solvents for use in the U.V. light treatment include water, C 1 -C 6  alkanols, dioxane, acetonitrile or tributyl amine, or aqueous mixtures thereof. If the starting material contains any of the trans isomer the latter can be separated or the cis/trans mixture can be converted by the defined process to a mixture of cis- and trans-1,2-epoxy propyl phosphonic and the trans isomer then separated and if desired converted to the cis isomer by irradiation with U.V. light. If the free phosphonic acid is used in the process it is preferred to isolate the product as a salt, e.g. the sodium or benzyl ammonium slat and if the starting material is an ester the ester product may be converted to the free acid or salt thereof by hydrolysis or reductive removal of the ester group. The end products are generally racemic mixtures which can be resolved into their optically active (+) and (-) forms. The ()(cis - 1,2 - epoxypropyl)phosphonic acid and salts thereof have antimicrobial properties. The starting materials I may be prepared by the following reaction scheme: In these reactions the compounds V are converted to I by epoxidation and the compounds VI are converted to I by oxidation with mercuric oxide. The phosphonic reactants and products may be in the form of the free acids, esters or salts. Compounds IV or their salts are obtained by reacting chlorophosphonic acid or ester or salt thereof with hydrazine hydrate at low temperature, generally below 0 C. and in an inert solvent. Compounds II can be obtained by the following reaction scheme: The salt, ester or free acid of the phosphorus acid may be used (a salt being shown) and compounds VIII are converted to 1,2-epoxy-2- chloro-ethyl phosphonic acid or salt or ester thereof by treatment with water, this being followed by treatment with methylhydrazine to form compounds IX which are finally treated with mercuric oxide to form II.

Patent GB-743511-A (GB)
Title: Improvements in or relating to the control of polyphase alternating current motors
IPC: B66B1/06
Filed: 1953-09-03
Abstract: 743,511. Automatic speed control systems. WEST & CO., Ltd., A., and STACEY..J. R. Aug. 25, 1954 [Sept. 3, 1953], No. 24381/53. Class 38 (4). [Also in Group XXXVII] A. slip-ring induction motor M for driving a hoist is braked by the application of directcurrent to its primary winding, such current being derived from an exciter EX having a field winding EXF. The rotor resistance R of the induction motor is regulated by means of a control lever L, and means are provided for varying the voltage of the injected directcurrent both as a function of the motor speed and also as a function of the secondary resistance so that, for any setting of the control lever, the motor speed tends to be stabilized at a corresponding value notwithstanding variations of the load driving the motor. For this purpose, the motor is coupled to a tachometer generator TCH supplying a number of relay windings Wl-W5 in series with a resistor r2 the value of which is varied according to the position of the lever L. Contacts Cl-C5 are operated at different current values by their windings Wl-Wo so that they close or open progressively according as the speed of the tachometer generator increases or decreases. These contacts are adapted, on closing, to cut out, in sequence, sections of a resistance r in series with the exciter field winding EXF. If, at any given setting of the lever L, the speed of the motor M becomes greater, for example, the voltage of the tachometer generator increases and one or more additional relay-contacts C1- C5 will close. The field excitation of the exciter EX is thus strengthened and the voltage output of the machine is raised whereby the braking effort of the main motor is increased, so stabilizing the speed of the motor. When the control lever is moved to a higher setting, the increased value of the resistance R tends to raise the motor speed, and, at the same time, the increase of the value of the resistor r2 permits such a higher speed to be attained. A relay winding w6 controls contact C6 connected across resistor r3 in series with field winding TCHw of the tachometer generator. If the control lever is moved rapidly to a low speed position while the motor is running at high speed, the contacts C6 open and reduce the voltage of the tachometer generator and so limit the current passing through relay windings Wl-WO to a safe value. The operation of the resistance R in response to the actuation of the lever L may be delayed slightly so that the variation of resistor r2 takes place in advance of that of the motor secondary resistance. When the lever L is in the minimum speed position, contacts k1 k2 are connected to short circuit substantially the whole of the resistance r. The exciter EX may be replaced by a selenium or mercury arc rectifier. The lever L is coupled to a drum controller governing the operation of interlocked contactors for power hoisting and lowering. The movement of the lever through a slotted gate actuates a change-over switch for establishing the dynamic braking connections.

Title: An electric selecting and starting switch for turbo starters
IPC: F02C7/277
Filed: 1949-09-23
Abstract: 664,321. Actuation of switches; retractive switches. BRITISH THOMSON-HOUSTON CO., Ltd., and CHAFER, H. J. Aug. 10, 1950. [Sept. 23, 1949] No. 24496/49. Class 38 (v). A selecting and starting switch for cartridgefired turbo-starters, comprises a rotary type time delay mechanism 11, a selector knob 6 containing a firing push button 1 and means to ensure that the selector knob cannot be moved whilst the time delay mechanism is in operation so that a minimum time must elapse between the firing of successive charges. A wheel 13 with diametrically opposed projections is loosely and slidably keyed on a slotted bush 12 fixed to the spindle 20 of the time delay mechanism 11. A wheel 8 attached to the end of a hollow slotted shaft 7 has three projections spaced 120 degrees apart, Fig. 3. The push button shaft 2 extends through the shaft 7 and carries a member 3 on which the moving contacts 5 are secured. The member 3 has three rods 4 which extend through holes in the wheel 8 and engage the face of the wheel 13. Assuming that the timing mechanism has operated the wheels 8, 13 are in the position shown in Fig. 3. If the selector knob 6 is now turned to its next position the rotation of the shaft 7 and with it the shaft 2 through 120 degrees turns the moving contacts 5 to a position where they can be depressed into engagement with a pair of the fixed contacts 17. The wheels 8, 13 are also turned clockwise through the same angle, an axially extending one of the projections on the wheel 13 being initially in a position to'hold a latching blade spring 10, Fig. 3 away from the projection on the wheel 8, which it abuts as the selector knob reaches its next position, another projection on the wheel 8 abuts the spring 10 and the springs 9, 10 lock the selector switch against further movement. If now the button 1 is depressed, the contacts 5 are brought into engagement with the selected contacts 17 and the rods 4 move the wheel 13 along the bush 12 against a spring 14 so that its axially extending projection disengages from the projection on the wheel 8. The timing mechanism 11 is now set in motion under the bias of the spring 14 and the wheel 13 is returned anticlockwise under the control of the mechanism to its original position where its axially extending projection abuts the next projection on the wheel 8 and holds the spring 10 aside. Stops 19 prevent the axial movement of the wheel 13 in this position, so that movement of the selector knob to the next position is necessary before the button 1 can be depressed again. The blade springs 9, 10 prevent the movement of the selector when the timing mechanism is in operation and a spring loaded plunger 18 carried by the selector knob depressable by the button and co-operating with slots in the switch casing prevents the operation of the push button except in the selected positions of the knob 6 and also prevents the movement of the knob 6 whilst the push button is depressed. A fuse testing push button switch 16 may be associated with each position of the selector knob 6.
