Title: Improvements in and relating to boring heads for diamond or like precision tools andwork holding chucks and the like
IPC: B23B29/034
Filed: 1942-12-04
Abstract: 561,975. Chucks. JEARUM, F. C., and BISHOP, H. S. Dec. 4, 1942, No. 17288. [Class 83 (iii)] Chucks for holding boring tools, particularly diamond tools, and like cutters or for holding work, have a mount that carries the chuck displaceably radially by means controlled by a scroll. The movement may be used to apply cut to single point boring tools or for turning parts of work concentrically. A spindle 20, on which an adapter sleeve 21 is secured by an end nut, ends in a screwed nose to receive a tapped boss carried by the back plate 12 of the body of the device. A closure plate 50 for the front of the chuck is secured to the plate 12 by screws and a dowel and carries projections that make a slideway 71 for a slide 70 carrying a chuck mount 72. A projection 80 secured at 81 on a transverse bore in the slide passes through a slot in the plate 12 and carries teeth that engage a scroll on a cap member 30 having a graduated flange 32 overlapping the body and acting with a zero mark or with a vernier on a ring 40 mounted on the body. A groove in the end of the cap 30 receives a flange on a ring 90 for locking, after adjustment of the slide, by a ring nut 23 screwed in the adapter 21. The nut 23 when screwed in the reverse direction serves also to start the adapter from any socket in which it may have been mounted. Grooves in the sliding projections of the plate 50 receive two shutter members 60, 61 that have relative movement in such manner .that the opening in the plate 50 is covered to exclude dust in all positions of the slide. The chuck mount 72 has a bore with a coned inner end to receive a range of split taper collets closed by a cap 74 screwing on the mounts. Two rings may be mounted behind the cap 31, each carrying an arm adapted to make contact with a peg in the back of the cap to limit the movement of the scroll and consequently of the slide in each direction. The rings turn on intermediate split rings that may be expanded to clamp the slip rings after adjustment. Oppositely located cutters in a boring tool may thus be set to give roughing and finishing cuts respectively.

Filed: 1933-06-17
Abstract: 403,031. Centrifugal machines. HONNICKE, G., 6, Lindauer Strasse, Berlin. June 17, 1933, No. 17311. [Class 23.] A centrifuge for the treatment of granular or fibrous material, for example that obtained from animal raw materials by decomposition, has a removable perforated basket 1 mounted in and rotating with the drum 3. The capacity of the basket corresponds to the effective capacity of the drum, and the perforations in its wall are of such size that coarse particles are retained in the basket while granular and fibrous material passes through and spreads over the wall of the drum. A filter bag 5 may be included in the apparatus. The basket 1 is fixed in a ring 2 secured to the angle ring 31 of the drum by bolts 4 and wedges 6. The nozzle 11 of a steam pipe 10 directs a jet of steam against the peripheral portion of the drum base and so facilitates the centrifuging of the liquid contents by raising the temperature of the drum. The stop valve 12 may be connected with the driving mechanism so that it is opened and closed automatically when the machine starts and stops. The liquids and gases pass through the pipe 8 to the condenser 13 where the steam meets cooling liquid from the nozzle 14. The liquids fall to the separator 15 having an outer vessel 15<1> to which the heavy constituent passes, while the light liquid, fat for example, remains in the inner chamber. The light liquid may be drawn off by a pipe 16<1> which has a covering hood to prevent the entrance of cooling liquid, and an overflow pipe 16 is provided for the heavy liquid.

IPC: G11B17/16
Filed: 1957-05-31
Abstract: 889,661. Automatic gramophones. HANSEN, H. C. May 27, 1958 [May 31, 1957], No. 7387/57. Addition to 862,004. Class 40 (2).  In an automatic gramophone in which records are supported on a stepped centre post-and released one by one to the turntable, means are provided for engaging the centre hole of the lowermost record and pulling said record down to an intermediate position in which a feeler member gauges the diameter of the record to adjust the start-of-play position of the pick-up, after which the record is released to the turntable. The apparatus is substantially as in Specification 859,372 but is provided with a centre-post having a two-position unseating lever, the appropriate operating cam on the control cam-disc being suitably modified to obtain the double movement of the unseating lever. The centre-post comprises a stepped channel-shaped element 500, Figs. 17 and 18, a double-toothed unseating lever 524 to which is attached, as by a pin or welding at 536a, a channel-shaped member 530 which surrounds the lever 524 and rests in the channel of the centre-post 500 so that ears 538 and 540 of the member 530 may slide up and down flat surfaces 542a and 542b on the centre post 500. The centre-post is provided with a member 512 at its upper end whereby records passing thereover are caused to be moved to the left, as viewed in Figs. 14, 15 and 16, and come to rest on the step 529 of the unseating lever 524. The member 512 is slotted to facilitate withdrawal of records, and its lowermost end terminates at a little more than the thickness of a record above the step 529. During the first part of an automatic cycle the lever 524 moves the lowermost record to the right against the ears 538, 540, Fig. 15, after which the lever 524 and member 530 is lowered to the intermediate position shown in Fig. 16 during which time a feeler member on the pick-up arm gauges the diameter of the record and sets the pick-up arm relative to a cam-follower frictionally coupled thereto so that the pick-up becomes preset to the correct setting down radius for the record tested. Further rotation of the cam-disc controlling the automatic cycle causes the unseating lever 524 to be withdrawn into the centre-post 500 so that the record supported on the lever 524 is dropped on to the turntable, after which the lever 524 is raised to its initial position. Specifications 757,303, 757,378, 757,379, 770,544 and 801,174 also are referred to.

Title: A process for the manufacture of optically active piperidine bases
IPC: C07D211/60
Filed: 1943-10-25
Abstract: Optically-active piperidine bases of the general formula:-<FORM:0574061/IV/1> wherein R represents a hydrogen atom or an alkyl group, are obtained by adding to a racemic base of the aforesaid general formula an optically-active acid, separating by fractional crystallisation the optically-active salts so formed and converting at least one of the salts into the corresponding base by treatment with alkali.  The products are, in some cases, useful therapeutically.  In an example, d-tartaric acid in ethanol is mixed with dl-ethyl-3-phenyl-piperidine-3-carboxylate in ethanol, the precipitated acid d-tartrate of d-ethyl-3-phenyl-piperidine-3-carboxylate is separated and recrystallised from methanol and converted into the d-base by adding 2N-sodium hydroxide; the combined mother liquors of the recrystallisations are evaporated to dryness under reduced pressure, the residue is treated with 2N-sodium hydroxide and extracted with ether and the extract is distilled at 1 mm. pressure to obtain a mixture of the optical isomers of ethyl-3-phenyl-piperidine-3-carboxylate, which mixture may be similarly resolved by means of l-tartaric acid in place of the d-tartaric acid to obtain the l-base.  Specifications 552,065, 563,665 and 564,741 are referred to.
