Title: Process and arrangements for simuitaneous lubrication and cooling of the piece of work and the cutting tool during machining operations
IPC: B24B55/02
Filed: 1957-12-30
Abstract: 872,637. Grinding. FOUQUET, E. Dec. 30, 1957 [Dec. 28, 1956], No. 40241/57. Class 60. In machining processes, a process for the simultaneous lubrication and cooling of the object to be worked as well as of the tool during the machining, comprises the step of projecting lubricant and cooling fluid in powerful jets converging towards the zone where the processing takes place, said jets being confined within a relatively constricted enclosure surrounding said processing zone, said jets and said enclosure being maintained during the whole duration of the machining process. An arrangement for the simultaneous lubrication and cooling of objects subjected to a machining process, comprises at least two opposing spouts having outlet openings disposed as closely as possible to the zone where the processing takes place, deflecting means disposed facing said outlet openings, so as to deflect jets of lubricant and cooling fluid springing from said spouts effectively to reduce dispersion of said jets, and an enclosure made of pliable material supported on the surface of the object to be worked. Lubricating and cooling fluid fed through conduits 6, 7 is supplied to the contact zone between grinding wheel 2 and workpiece 1 through nozzles 4, 5. Side screens 8, 9 provided on either side of the grinding wheel have internal deflecting surfaces 14 and plane front surfaces 10, 11 to which are secured elements 131, 131 adopted to the radius of the workpiece. Curved plates 15, 16 are adjustably secured to extensions of the nozzles. Members 23, 24 are secured to the plates 15, 16 by pins 21, 22 engaging selectively holes 19, 20 in the plates. Secured in the members 23, 24 are the short sides 27, 28 of a pliable frame, the long sides 29, 30 of which are reinforced by metal wire helices 31, 32. The frame encloses the working zone, and is provided with a manipulating handle 35. At both sides of the workpiece is provided a rigid support 36 concentric with the workpiece and secured to a base 38 mounted on a carriage 39. A stack of resilient strips 40 is secured at one end to the support 36 ; the outer strip 42 has secured to its free end a rod 43 having two rods passing through a part 46 of the support 36 and carrying nuts 47, 48 whereby the outer strip is given a diameter slightly less than that of the finished workpiece so that it is not contacted by the grinding wheel. Specifications 847,411 and 847,855 are referred to.

Title: Preparation and use of í¸-3ª-hydroxy-androstene compounds
IPC: C07J1/00
Filed: 1964-10-02
Abstract: Steroids of the Formula II are prepared from steroids of the Formula I by hydrogenolysis <FORM:1073637/C2/1> R is keto or ethylenedioxy, R1 is H or acyl; and X is chlorine, bromine or acyloxy.  The acyl groups are derived from hydrocarbon carboxylic acids of less than 12 carbon atoms which are optionally substituted.  The steroids II may then be (a) when R is ethylenedioxy, treated with a strong acid to give the 17-ketones; and (b) when R is keto, treated with an alkali metal acetylide in alcohol solution or with diethynyl magnesium bromide to give 17a -ethynyl-D 5(10) -19 - nor - androstene - 3b ,17b - diol, which may be oxidized with chromic acid in pyridine to give 17a  - ethynyl - D 5(10) - 19 - nor - androsten - 17b  - ol - 3 - one.  This may then be isomerized with acid or alkali to 17a -ethynyl-19-nor - testosterone. Alternatively this last-named product may be prepared directly from the D 5(10) - 3b  - ol by Oppenauer oxidation. The 17a  - ethynyl - 19 - nor - testosterone may subsequently be esterified.  17 - Ethylenedioxy - 6 - chloro - or bromo-D 5(10) - 19 - nor - androsten - 3b  - ol is prepared by oxidizing 3 - acetoxy - 17 - ethylenedioxy - D 5 - androsten - 19 - ol (prepared from the 17-one) to give 17 - ethylenedioxy - D 5(10) - 19-nor - androsten - 3b  - ol - 6 - one acetate, reducing this to a mixture of the 6a - and 6b -diols and treating this with thionyl chloride or thionyl bromide. 6-Acetoxy-D 5(10)-19-nor-androsten-3b -ol -17-one (a mixture of the 6a  and 6b  isomers) is prepared from D 5-androstene-3b ,19-diol-17-one and lead tetraacetate. The diacetate of 17-ethylenedioxy - D 5(10) - 19 - nor - androstene - 3b ,6-diol (a mixture of the 6a  and 6b  isomers) is prepared by acetylation of the 3-monoacetate.

Abstract: 1323145 Tape recorders; track selecting MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 21 Aug 1970 [21 Aug 1969 (2)] 40427/70 Heading G5R A tape recorder for use with twin-track tape cassettes includes two sensors to detect the presence or absence of two index members on the cassette either to allow one track to be recorded or both tracks to be reproduced. The sensors are provided in, e.g. a language study tape recorder whereby erasure of the programme track 37, Fig. 3, is prevented, recording of the student track 35 in the same direction A is allowed, standard twin-track cassettes (with the recordings being in opposite directions) may be played, and the programme track may be reproduced on conventional cassette tape recorders. In a language cassette, Fig. 6, breakout index member 142 is absent, causing interlock member 155 to pivot in direction B, and member 143 is present, allowing record button 146 to be depressed when track selector 158 is rotated to align notch 160 with the button 146. Recording is therefore only allowed on the upper student track. A blank cassette, having both index members present, conditions the sensors to allow via notch 159 recording of a programme on the lower track but not on the upper track. In a modification (Fig. 7, not shown) sensor 151 directly operates a switch (255) to disable the the motor and energize a warning buzzer and/or lamp if an inadmissible selection is made by a manual track selector (Fig. 8, not shown).

Abstract: 1,111,494. Transistor amplitude selecting circuits. BILLMAN REGULATOR AB. 27 Sept., 1965 [28 Sept., 1964], No. 41004/65. Heading H3T. [Also in Divisions G1 and G3] A first Wheatstone bridge H, Fig. 1, contains a thermistor R4 responsive to room temperature, and a second Wheatstone bridge B contains a thermistor R9 responsive to temperature in a ventilation duct, the measuring diagonals of the bridges being interconnected with transistors T1, T2, such that when the duct temperature is above a predetermined value, only the output of bridge H is connected to the terminals 1, 2, and when the duct temperature falls below the predetermined value, only the output of bridge B is connected to the terminals 1, 2. The signal at 1, 2 is used to control the ventilation equipment. Provided the value of R9 is low enough, the transistors are both non-conducting, and a voltage across a potentiometer P2 in the diagonal of bridge H appears via a resistor R5 and a portion of a potentiometer P3, at 1, 2, and no voltage occurs across the potentiometer P3, which is connected in series with transistor T2 in the diagonal of bridge B. When the thermistor R9 increases in value sufficiently to make the point a in bridge B positive with respect to the point b, the transistors T1 and T2 conduct so that a voltage is developed across potentiometer P3, a portion of which is applied to the terminals 1, 2 via transistor T1 which short-circuits the output of bridge H. In an alternative embodiment (Fig. 2, not shown) one pair of arms of each of the bridges (H, B) is constituted by a potentiometer (P4, P5) and the measuring diagonals each contain two series connected resistors (R12, R13, and R16, R17) from the respective junctions of which connections are made to the emitters of transistors (T3, T4) the collectors of which are connected together and to one terminal (2) and the bases of which are connected together and through a resistor (R19) to the negative bridge supply. Whichever of the bridges provides a more positive voltage at the junction of its diagonal resistors predominates, and its measuring voltage is applied to the terminals (1, 2).

[Also in Division F4] In a vehicle headlamp arrangement, filaments mounted to provide beams directed to right and left for use when the vehicle is negotiating a turn are selectively illuminated by a centrifugal switch. The switch comprises a generally U- or V-shaped vacuum tube 5 containing a quantity of mercury 4 which flows into one or other of the limbs of the tube under centrifugal force when the vehicle is turning and thereby connects a middle contact 6 to one of the end contacts 7, 8 so completing the circuit to the appropriate filament. An inwardly projecting nose 12 prevents the mercury from reaching the end contacts when the vehicle traverses a pot-hole or executes minor steering adjustments.
