Title: Improvements in or relating to the preparation of steroid substances
Inventor: NICHOLLS RALPH JOHN
IPC: C07J5/00
Filed: 1953-12-31
Abstract: Steroid (especially allo-steroids) of the general formula <FORM:0757239/IV(a)/1> (wherein R represents an acyl group) are manufactured by reacting a compound of the general formula <FORM:0757239/IV(a)/2> (wherein R and R1 represent acyl groups) with bromine in the presence of an inert organic solvent.  The reaction is advantageously carried out at 0-45 DEG  C. under homogeneous conditions using about one mol. of bromine per mol. of steroid starting material.  The products may be converted, without purification, into 21-acyloxy compounds by treatment with an alkali metal salt of an organic acid in a suitable solvent, if desired after first subjecting the 3-acyloxy group to an acid hydrolysis or alcoholysis.  In examples: (1) a solution of 3b  : 20-diacetoxy - 11 - oxo - 17 : 20 - oxidoallopregnane in chloroform containing a trace of hydrogen bromide is treated with a solution, added dropwise, of bromine in chloroform, and the crude 21-bromo-3b -acetoxy-17a -hydroxy-11 : 20-dioxoallopregnane is refluxed with anhydrous potassium acetate in acetone to produce 3b  : 21 - diacetoxy - 17a  - hydroxy - 11 : 20-dioxoallopregnane; (2) as in (1) but with an intermediate reaction of the crude bromination product with methanol and a solution of hydrogen bromide in chloroform, the final product being 21-acetoxy-3b : 17a -dihydroxy-11 : 20-dioxoallopregnane; (3) the proportion of bromine in (1) is reduced and the addition of hydrogen bromide omitted.

Title: Improvements in and relating to writing instruments
Inventor: HARE RONALD WILLIAM
IPC: B43K24/06
Filed: 1957-11-26
Abstract: 849,460. Writing instruments. JOHNSON, MATTHEY & CO. Ltd. Nov. 21, 1958 [Nov. 26, 1957], No. 36845/57. Class 146(3). In a writing instrument in which a writing unit carrier is projected and retracted by rotation of an operating member rotatably but axially immovably mounted in a body portion in which the carrier is slidable, the operating member and the carrier are formed with cooperating parts consisting of a pin or projection and a cam track comprising a pair of helical cam surfaces extending from a common apex and against which cam track the pin or projection is constantly resiliently urged, whereby rotation of the operating member in either direction of rotation will cause projection and/or retraction of the writing unit. As shewn a ball-point pen comprises a writing unit 1 mounted in a tubular carrier 3 by means of a flange la at the rear end thereof which is held in engagement with a shoulder 3a in the carrier 3 by means of a threaded plug 3b. The carrier 3 is slidable and relatively rotatable in a tubular operating member 4 haing a reduced diameter portion 5 which terminates in a bevelled face 8. The face 8 constitutes two helical cam surfaces 9, 10 which meet at their upper ends (as seen in Fig. 1) in a notch 22. A rotatable collar 6 is mounted on the part 5 of the member 4 and secured against axial displacement by a bush 7. A tubular body member 12 is frictionally fitted at one end over the collar 6 and has a slot 17 which accommodates a laterally projecting pin 11 on the carrier 3. A compression spring 19 is mounted in the body member 12 surrounding the writing unit and is disposed between a shoulder 21 in the body and a flange 20 on the forward end of the carrier 3 so as to urge the pin 11 on the carrier in to engagement with the face 8 of the operating member 4. A sleeve 15 is fitted in the front end of the body member 12 and is internally threaded to engage a barrel tip 25. A barrel portion 23 of plastic encloses the middle part of the pen and a metal cap 24, rotatable relatively thereto, is frictionally engaged over the operating member 4. When the writing tip is projected, as in Fig. 1, the pin 11 on the carrier 3 is engaged in the notch 22. When the cap 24 and operating member 4 are rotated in either direction the pin 11 is forced out of the notch 22 and rides down the cam face 9 or 10 to the lower end thereof under the influence of the spring 19, the writing tip being thereby retracted. Further rotation of the cap 24 in either the same or the opposite direction restores the pin 11 to the notch 22 and forces the writing unit 1 forward to projected position against the rearward bias of the spring 19. The invention is also applicable to mechanical pencils, in which case the ball-point writing unit 1 is replaced by a lead carrier formed integrally with the carrier 3.

Filed: 1975-09-09
Abstract: 1506329 Automatic control of combine harvesters MASCHINENFABRIK FAHR AG 9 Sept 1975 [20 Sept 1974] 37093/75 Heading A1F The amount of grain produced by a combine harvester is measured by a device placed at 9 near the upper end of the grain elevator 1 where the grain is projected in an approximately horizontal stream towards the inlet 8 of the grain tank. The measuring device may consist of two vertical rows of photocells 14, one on each side of the path of the grain, there being a central strip lamp placed so that the grain passes between the lamp and one or other of the rows of photocells. A control photocell keeps the power of the lamp constant. The signal produced by each photocell depends on the amount of grain passing between it and the lamp so that by connecting all the photocells in series the total flow of grain can be measured. In another form the grain is caused to strike a spring loaded flap which moves through an angle corresponding to the flow of grain and varies a resistor to indicate the amount of grain. An acoustic measuring system is also suggested. The measured value may be used for indication or control purposes.
