Title: Quick acting depth gauge for a drilling machine or like machine tool
IPC: B23Q5/52
Filed: 1929-05-28
Abstract: 331,341. Heide, H. C., (Cincinnati Bickford Tool Co.). May 28, 1929. Dilling.-In an adjustable depth gauge for a drilling or like machine tool sleeve, 4 mounted on the drill-head 1 and carrying the drill-spindle 3 is traversed by power-operated mechanism which is automatically disconnected when the sleeve is near either end of its travel or after a predetermined movement of the sleeve, such movement being controlled by an indicating dial plate. The power feed is derived from a worm 9 driving a, worm-wheel 8 which by means of a friction clutch 13 may be, locked to a disc 14 keyed on the feed-shaft 7. The friction clutch is engaged by a cam 16 mounted on a sleeve 17 operated by a cam surface 19 on a sliding block 20 which is moved axially by a fork 24 carried by a rod 25. A bracket 27 secured to the framing supports a fixed bearing member 29 which carries a, rotatable dial-head 28 on which the graduated dial 45 is adjustably mounted. The head 28 is provided with external teeth engaging teeth 31 on the block 20 so that any rotation of the shaft 7 is communicated to the dial-head which is arranged so that less than one complete rotation of the dial-head effects the full travel of the drill sleeve. The dial-head coacts with a trip lever 33 for disconnecting the drive from the drill sleeve. For this purpose the dial-head carries a lug 36 which engages with a wedge 35 on the trip lever to shift the clutch forks 24 near the ends of the travel. A quick throw-over 37 is provided for the trip lever. The rod 25 moves in a block 40 secured to the dial-head and carrying pivoted lever arms provided with segmental teeth engaging rack teeth on the rod 25 so that by rooking one of these arms on its pivot the power feed may be disengaged and the drill-head fed manually by rotation of the dial-head by the arms 39. The dial-plate 45 carries a swivelling worm 50 which may be engaged with worm teeth 51 on, the dialhead for fine adjustment of the dial. Coarse adjustment is effected by hand after the worm has been disengaged. The dial carries a screw 47 which is adapted to engage the trip lever to disengage the power feed when the desired depth of cut is attained. When not required the screw 47 may be withdrawn to an inoperative position. The screw 47 is arranged in the path of movement of the lug 36 so that it is not possible to set the dial for drilling a hole beyond the possible length of travel of the drill sleeve.

Filed: 1944-09-01
Abstract: 632,777. Protective arrangements for electric meters. GENERAL ELECTRIC CO., Ltd., VEEVERS, J. F., and THOMAS, J. F. Sept. 1, 1944, No. 16717. [Class 37] The indicating element, of an electric meter, upon movement of a predetermined extent causes, by the movement of a detent, the opening of a normally closed switch to effect the interruption of the working current through the meter, either directly or indirectly. When the pointer 22 moves into contact with either stop-pins 24, 25 (e.g. due to an overload) the cam extension 43 of lever 27 is rocked (indirectly by lever 26 or directly by lever 27) out of engagement with tooth 42 of detent lever 41. Rod 36, urged by spring 38, moves upwards, causing the lever 41 to disengage from shoulder 39 against the light biassing-spring 44 and the opening of the normally-closed switch 33, 34 and 35. The switch may normally carry the full working current of the meter or its opening may cause the actuation of a relay effecting the interruption of the current. Re-setting of the mechanism is carried out by the depression of a push-button (not shown), which pushes the rod 36 down until the switch is closed, when the lever 41 again registers with shoulder 39 and tooth 42 engages with cam 43. Levers 26, 27 return to their normal positions under the influence of spring 32. Figs. 1 and 2 (not shown) disclose an embodiment in which the lever carrying the stop also carries the detent and part of it is made of magnetic material so that its re-setting is due to the magnetic force between it and the usual magnetic portions of the meter.

Title: Improvements in or relating to a process for the surface treatment of semi-conductormaterial
IPC: H01L21/20
Filed: 1959-05-15
Abstract: In the deposition of silicon from a gaseous or vaporous compound thereof on to an electrically heated body thereof, the compound is initially brought into contact with the body under such conditions that erosion instead of deposition is effected so as to purify the surface of the body.  Similar conditions may be used to interrupt deposition so as to remove an undesirable polycrystalline deposit from a monocrystalline body and/or at the end of deposition to purify the surface of the final deposit.  The axis of a body in the form of a silicon rod is preferably the (111) crystal axis.  In the deposition of silicon from a mixture of silicon tetrachloride and hydrogen, relationships between the ratio SiCl4/H2 and temperature for deposition and erosion are given <PICT:0914042/III/1> in Fig. 2 (not shown).  Similar conditions apply using a mixture of silicochloroform and hydrogen except that the minimum ratio of silicon compound to hydrogen for erosion is about 0,5 instead of about 0,3 and hydrogen chloride is preferably present in addition to hydrogen.  The hydrogen chloride may be produced by the addition of steam.  As shown, metered streams of hydrogen from line 22 and a mixture of hydrogen and silicon tetrachloride from line 21 are mixed in a line 23 and then injected into a glass or quartz vessel 13 surrounded by a reflector 38 and containing a pair of silicon rods 28 and 29 connected by a current-conducting bridge 30 of silicon, carbon, or graphite and having terminals 26 and 27 respectively of carbon or graphite pressed into silver in a hollow water-cooled silver base 24, terminal 27 being insulated from the base 24.

Title: Process for the manufacture of alkylated phenols and their hydrogenated products
IPC: C07C37/52
Filed: 1926-07-05
Abstract: 254,753. Chemische Fabrik auf Actien vorm. E. Schering. July 4, 1925, [Convention date]. Alkyl phenols and cyclohexanols. - Alkyl phenols and cyclohexanols are obtained by the catalytic hydrogenation of the condensation products of a ketone with a phenol. The condensation product splits at the bridge between the phenolic residues and each component then takes up either one or seven atoms of hydrogen. Thus p-dioxydiphenyldimethylmethane yields either a mixture of p-isopropylphenol and phenol or a mixture of 4-isopropylcyclohexanol and cyclohexanol. The production of the alkyl phenols is effected with the aid of a catalyst comprising nickel or other hydrogenating catalyst mixed with bismuth, whilst the formation of the alkyl cyclohexanols requires a slightly higher temperature and a catalyst consisting of nickel or other hydrogenating catalyst to which manganese has been added. The use of pressure in either case is advantageous. Examples are also given of the hydrogenation under pressure of 4-dioxy-3-dimethyldiphenyldimethylmethane, obtained by the interaction of acetone and o-cresol in the presence of concentrated hydrochloric acid, whereby on the one hand a mixture of 2-methyl-4-isopropylphenol and o-cresol is obtained and on the other hand a mixture of 2-methyl-4-isopropylcyclohexanol and 2-methylcyclohexanol. Specification 252,594 is referred to.
