Title: Spiral taper grinding fixture
IPC: B24B3/04
Filed: 1966-06-08
Abstract: 1,089,620. Grinding. R-O. MANUFACTURING CO. June 8, 1966 [July 12, 1965], No. 25631/66. Heading B3D. A spiral taper grinding fixture comprises means 12 mounting a work spindle 14 on a base 10, spiral feed means for simultaneously rotationally and axially feeding the spindle, and means responsive to the feed of the spindle for transversely shifting the same relative to the base. The base 10 consists of a bottom plate 18 on which is a fixed plate 20 which is formed with a circular opening 108 for receiving the circular portion 106 of a sine bar swivel member 104 and supports tracks 22, 24 which co-operate through balls 32, 34 with tracks 28, 30 secured to the bottom plate 26 of a head 12, the tracks permitting movement of the head in a direction transverse to the axis of the work spindle 14 mounted in bearings in the head. One end of the work spindle has a chuck 16 for a spiral cutting- tool T to be ground by a wheel W, and the spindle is formed with a reduced portion 42 connected by an indexing mechanism 45 to a sleeve 44 on the portion 42. The mechanism 45 includes a notched collar 46 on the sleewe 44 and a knob 48 which is secured to the portion 42 and has a detent 50 for engagements with the notches 51. The end of the sleeve 44 is formed with a pinion 82 which engages a driven rack 78 slidable in a slot 76 formed transversely of the spindle axis in a yoke 74 mounted on the workspindle. The rack 78 is pivotally connected by a pin 80 to a driving rack 70 which is slidable in a slot 69 in a top plate 56 of the head and engages a pinion 68 on a shaft 64 rotatable by a crank 66. The top plate is rotatably adjustable to vary the angular position of the driving rack 70 and is securable in adjusted position by a clamp 58. The yoke 74 is .slidably supported on rails extending parallel to the spindle axis and a pin 94 extends dowwardly from a plate 92 secured to the yoke into a shoe 96 slidable in a slot 102 formed in the sine bar swivel member 104. An indicator arm 110 extends from the circular portion 106 of the member 104 and co-operates with a scale whereby the angular position of the member, and hence the slot 102, relative to the spindle axis can be determined. In operation, the top plate 56 is rotatably adjusted to position the driving rack 70 so that as the rack is moved by rotation of the crank 66 and pinion 68, the pin connection 80 moves the driven rack 78 longitudinally and parallel to the axis of the spindle 14 to effect simultaneous rotation and axial movement of the work spindle. The axial movement imparted to the spindle, and hence the yoke 74, causes the shoe 96 to move along the slot 102 in the member 104 which is so adjusted that as the shoe moves, the head moves transversely to the work spindle axis by way of the tracks 22, 24, 28, 30 and balls 32, 34 to transversely displace the work spindle in accordance with the taper of the tool. The indexing device 45 is used to present successive flutes of the tool to the grinding wheel W.

Title: Improvements in or relating to processes for the treatment of electrolyte
IPC: C02F1/48
Filed: 1954-09-09
Abstract: 761,016. Purifying liquids; imparting special properties to water. LOOSLI, H. Sept. 9, 1954 [Sept. 9, 1953 ; July 8, 1954], No. 26161/54. Class 46. For preventing the formation of, or eliminating, coherent scale from salts in an electrolyte, e.g. calcium carbonate in tap water, the electrolyte is subjected to a series of electromagnetic fields of short duration, the voltages and currents generating the field and the duration of the pulses being such that practically no electrolysis occurs. The apparatus of Fig. 1 includes a direct current source 1, a resistor 2, a change-over switch 3 with an armature 34 and fixed contacts 35 and 36, a capacitor 4, a self-induction coil 5, and, in parallel with this coil, electrodes 7 and 8 in a vessel 6 through which flows the electrolyte being treated; rocking of the armature to contact 35 and then 36 causes charging of the capacitor and then its discharge through the coil 5 to produce damped oscillations and generate a brief electric field between the electrodes 7 and 8, the frequency of the oscillation circuit 4, 5 being sufficiently high, e.g. 10,000 c/s or more, that no substantial deposition occurs at the electrodes. The apparatus of Fig. 2 differs from that of Fig. 1 in that a glow discharge tube 13 is employed instead of the change-over switch 3 ; when the capacitor 4 is so highly charged that the firing voltage of the discharge tube 13 is reached, the capacitor discharges through the coil 5. According to an example for treating tap water in the apparatus of Fig. 1 to precipitate calcium carbonate as fine crystals, or to disintegrate any calcium carbonate crust already present, the current source 1 is of voltage 2,000, the capacitor is of capacitance 4 microfarad and forms with the coil 5 an oscillation circuit of natural frequency 30,000 c/s, the damped oscillations die after 3 oscillations, i.e. after 100 microsec., the change-over switch is adjusted to impulse frequency 1.5 per second, and there are electrode currents of 120 amp.

Title: Electric reciprocating compressor particularly for small refrigerators
IPC: F25B31/02
Filed: 1955-09-16
Abstract: 783,377. Compressors. DOLZ, H. Sept. 16, 1955 [Sept. 27, 1954], No. 26597/55. Class 8(1). In a compressor comprising a cylinder member having a piston member therein, one member being connected to an electric reciprocating motor to be reciprocated thereby, the other member reciprocates relative to the first member by forces of gravity and inertia, such relative movement causing compression of a gas within the cylinder. In the embodiment of Fig. 1 the piston 25 is freely slidable in the cylinder 1 which has spring-loaded valve plates 2, 3 covering its ends and is reciprocated via the shaft 10 by an electric motor. The piston rests against the valve 3 and gas enters the space 19 through slots 26. When the cylinder is moved to the right, the piston will move to the right and at the end of the stroke of the electric motor when the cylinder is moved to the left, due to its weight and inertia the piston will continue to move to the right, compressing the gas in the space 19 and opening valve 2. The compressed gas flows via space 6 and tube 12 into chamber 7 and through bore 13 in supporting shaft 11 to pressure chamber 14 from whence it is delivered via check valve 28 and nipple 27. On the reverse stroke, compressed gas is delivered via valve 3 to chamber 7 direct. In another embodiment the valves 2, 3 are replaced by valves arranged in the cylinder wall at some distance from the cylinder ends so that gas trapped between the valve and the cylinder end will form a cushion for the piston. Fig. 4 shows the compressor 58 mounted in a hermetically sealed casing 65. The shaft 10 carries the motor armature 69. When alternating current is supplied via leads 78, 79 to the stator winding 80 the armature 69 is drawn into the stator during both the positive and negative half-cycles of the current. During the dead phase the armature is pulled out of the stator by a return spring 82. In Fig. 1, the piston is shown as double acting, but it could be single acting and by using a differential piston, or by suitably positioning the valves in the second embodiment, or by using several compressors, multi-stage compression can be obtained. Also, instead of a free piston in a reciprocated cylinder, the reverse arrangement could be employed. The reciprocating masses together with their resilient members can be tuned to the frequency of the current supplied.

Title: Manufacture of oxidation products of steroids having a semi-cyclic double bond
IPC: C07J75/00
Filed: 1950-07-26
Abstract: The invention comprises D 17-3 : 12-diacyloxypregnen-21-als, and the manufacture thereof and of other D 17-pregnen-21-als, and of 17-ketones of the androstane and aetiocholane series, by treating a D 17-21-alkylidene- or -aralkylidene-pregnene with an oxidizing agent (e.g. ozone, chromic acid, or hydrogen peroxide in the presence of osmium tetroxide).  The starting materials may be further substituted, e.g. in the 7- and 11- or especially the 3- and 12-positions, e.g. by keto, hydroxy, acyloxy, alkoxy or aralkoxy groups or halogen atoms, and may contain double bonds in the 4-, 5-, 9- or 11-position.  The substituents in ring C have considerable influence on the course of the reaction; thus if a hydroxy group in the 12-position is esterified with a lower organic acid the product is mainly the 17-ketone, whereas if it is esterified with a higher organic acid the D 17-pregnene-21-al is obtained.  Double bonds may be protected where necessary, e.g. by means of halogen or hydrogen halide, and oxidizable hydroxy groups by esterification or etherification, though if desired the latter may be simultaneously or separately oxidized to keto groups.  In examples: (1) D 17 - 3a  - acetoxy - 12 - a  - tosyloxy-21-benzylidenepregnene is oxidized with hydrogen peroxide and osmium tetroxide in ether in the presence of sodium sulphate to produce D 17 - 3a  - acetoxy - 12a  - tosyloxy-pregnene-21-al; (2) the oxidation in (1) is effected with ozone in ethyl acetate, the ozonide being decomposed with hydrogen in the presence of a palladium-calcium carbonate catalyst and the product purified by chromatography; (3) D 17 - 3a  : 12a  - diacetoxy - 21 - benzylidene-pregnene is ozonized in ethyl acetate and the ozonide decomposed with zinc and acetic acid, yielding 3a  : 12a -diacetoxyaetiocholan - 17 - one; (4) D 4 : 17 - 3 - keto - 21 - benzylidenepregnadiene is oxidized with chromium trioxide in acetic acid and ethylene chloride to D 4-androstene-3 : 17-dione (isolated by chromatography). Specification 711,210 is referred to.
