Abstract: 1357394 Steroid glycosides DR KARL THOMAE GmbH 27 Oct 1971 [27 Oct 1970] 49936/71 Heading C2U The invention comprises compounds of formulae wherein R 1  is H or OH; R<SP>1</SP> 1  is H, carboxylic acyloxy, benzyloxy, benzyloxycarbonyloxy, trimethylsiloxy or tetrahydropyranyloxy; R 2  is H, F, Cl, CN, C 1 -C 4  alkyl or C 1 -C 4  alkoxy; R 3  is CO 2 H, CN, alkoxycarbonyl, aryloxycarbonyl or aralkoxycarbonyl; R<SP>1</SP> 3  is as R 3  but not CO 2 H; and R 5  is carboxylic acyl, benzyl, benzyloxycarbonyl, trimethylsilyl or tetrahydropyranyl. Compounds I are prepared from compounds IIa (wherein R<SP>1</SP> 1  is H or protected hydroxy; and OR 5  is protected hydroxy) by removing the protecting groups (e.g. by hydrolysis or hydro- .genolysis), optionally preceded by hydrolysing R<SP>1</SP> 3  to a free carboxy group which may subsequently be re-esterified. Compounds IIa are prepared by reaction, preferably in the presence of a .base, of a phosphonate of formula where R 4  is C 1 -C 4  alkyl, with the corresponding 17#-formyl steroids, the latter being obtainable from the corresponding 20,21-dihydroxypregnanes by oxidation with metaperiodic acid or sodium periodate. Compound I (R 1 =OH; R 2 =H; R 3 =CN) may be converted to its 3<SP>111</SP>-O-acetyl and 3<SP>111</SP>,4<SP>111</SP> - O - isopropylidene derivatives which are said to be cardioactive. Compounds I are said to be cardioactive, and may be made up with carriers into pharmaceutical compositions for oral, parenteral and rectal administration.

Title: Window opener mechanisms
Inventor: GREENLAND RALPH
IPC: E05F11/44
Filed: 1965-12-02
Abstract: 1,093,470. Window operating mechanism. GENERAL MOTORS Ltd. Nov. 10, 1966 [Dec. 2, 1965], No. 51159/65. Heading E2M. A window opening mechanism for a slidable window has a pivoted arm 8 to move the window, a catch mechanism including an arcuate toothed rack 2 and a pawl 14 to engage the rack and hold the arm in a fixed position, and a pivoted cam 13 shaped and arranged so that initial angular movement of the cam in either direction disengages the catch mechanism and further angular movement of the cam turns the pivoted arm. Arm 8 has tension spring 9 connected to it to counterbalance the weight of the window and has a frictional load applied to it, e.g. by nylon buttons (not shown) on the arm bearing against a part of the base such as rack 2 so as to resist pivotal movement on the spindle 5.: Pawl 14 is spring-loaded by means of compression spring 16 in guide box 15. When the plunger is in the position shown, the tip 17 of it engages in the teeth of rack 2 and thus holds arm 8 in a given position. Cam 13 furnishes the means of releasing the pawl plunger 14 and of moving the lift arm. For this purpose, a pair of sloping cam surfaces 18 are provided at the end of the cam forming a V-shaped depression in the apex of which another part of the tip 17 of the pawl 14 seats when the window is stationary. When the cam 13 is turned in either direction by means of a handle (not shown), the initial movement of the cam raises the pawl clear of the teeth of the rack, the spring 16 being compressed. Further rotational movement of the cam effects angular movement of arm 8 by the engagement of one of two projecting parts 19 of the cam with the side of pawl 14. When rotational movement of the cam ceases, the pressure of pawl 14 on sloping cam surface 18 tends to restore the cam 13 to its original central position so that the tip of the pawl centres in the apex of the V-shaped depression and re-engages the teeth of the rack. To ensure the return of cam 13 to its central position, a helical centring spring 20 is provided having its coils supported by a tab 21 on the guide box 15 and its ends 22 inserted into a slot 23 in the cam 13. Stops 24 for the spring 20 are supported by a projection 24A from the guide box 15.

The spindles are driven through gearing and the clutches are selectively automatically actuated, the ratio of the gearing being determined by the spindle speed required. The indexing of the spindle carrier is effected by a Geneva type mechanism 93, 94 and 95 operated by an actuator 90 and through gearing to effect the required angular movement of the carrier which is determined by the number of work stations in a predetermined machining cycle. The spindle drum is looked in each of its indexed positions by a locking pin 115 which engages in a recess 117 provided at each required indexed position of the drum, the pin being actuated by hydraulic means 120. The drive to the drive shaft 10 is effected by belt and pulley 48, 49, 50 and gearing from a main motor 44 mounted on the machine frame housing 5. A plurality of fluid actuated cross slides 6 and 8 and end slides 7 and 9 are provided which relate to the number of work stations and the operations to be performed on workpieces carried in chucks carried in the spindles 12, 13 and 14. The operational sequence of the machine is described with reference to Figs. 21 and 22 (not shown). It is stated that operation of a pair of clutches in opposition may be effected to effect braking of a spindle.

A heat exchanger comprises a casing 15 containing a metallic, fluid-pervious mass 18 in which is embedded heat exchange tubes 16 of elongated, e.g. oval, cross-section, extending between tube plates (23, 24, Fig. 3) the tubes 16 being arranged with their longer dimensions parallel and uniformly spaced over substantially the whole length of that dimension, and the mass being bonded to the tubes. The arrangement shown includes additional tubes 17 of circular cross-section in casing zones where elongate tubes cannot conveniently be utilized. Methods described for forming the mass are similar to those described in Specification 1,124,076. In use, the casing may be connected into the radiator hose or other section of a vehicleengine cooling system, whereby water flows through the tubes in heat-exchange with another fluid, e.g. oil, which flows through the pervious mass and over the tubes between an inlet 21 and an outlet 22. In further forms described (Figs. 6 and 7) the porous mass including the assembly of tubes and tube plates is prefabricated as a separate rectangular unit with imperforate side-plates (130, 131).

Filed: 1966-11-25
Abstract: 1,166,059. Feeding mills. J. MAIER. 25 Nov., 1966, No. 52787/66. Heading B2A. [Also in Division G3] A mill has a grinding chamber 1 enclosing a rotary grinding mechanism, viz. a hammer mill, driven by an electric motor 5. Material to be ground is continuously fed from a hopper 3 by a conveyor 2 into the mill, and ground material is discharged via an electromagnetically-operated shaker trough 4 or a screw. This conveys at right angles to the direction of discharge of ground material. Ground material is thus dammed in the mill discharge duct 10, material remains in the chamber for a predetermined period, by speed control of the feed and discharge devices. In operation, if the power input to the motor 5 increases, e.g. because more energy is required in the grinding chamber 1, the operating voltage for the trough 4 increases and consequently the discharge rate, since the trough is powered via a transformer 6 and control device 7 in the circuit for the motor 5. The power input is thus set by the control 7 and the energy available for grinding is maintained constant, the degree of grinding being determined by the quantity of material fed in. The electrical coupling between the conveyor 4 and the mill 1 may be replaced by a mechanical coupling.
