Title: Buffing wheel
Inventor: CHURCHILL GEORGE RICHARDS
IPC: B24D13/08
Filed: 1963-11-12
Abstract: 1,019,542. Grinding. GEORGE R. CHURCHILL CO. Inc. Nov. 12, 1963, No. 44662/63. Heading B3D. A corrugated buffing element for a buffing wheel comprises an elongated strip of multi-ply surface treating material folded upon itself into a U-shape in cross-section and provided with transverse uniform corrugations, and means for retaining the corrugations in position. The element may be formed into a buffing wheel section by being wound into a single ring or helically into two or more coils. The element is formed of multi-ply cloth 34, Figs. 8 and 9, or fabric impregnated with abrasive material, the plies being secured together by stitching 36 and folded into a U-shape. A wire 26 is positioned within the fold by a guide wheel 42 supplied with the wire from a straightening device 40 and a reel 38, the wire being accurately positioned by a tube 46 having its end adjacent a nozzle 72. A thermoplastic hot melt adhesive is supplied from a reel 50, feed wheels 54, 56, a heated receptacle 58 having a driven wheel 60, a heated passageway 62 and a nozzle 66 connected to a dispenser 68 carrying the nozzle 72 so that adhesive is applied, as shown at 51, to an inner part of the folded element and about the wire 26. The element then passes between rollers 82, 84 which form corrugations in the element, the corrugations being pressed tightly against one another by rollers 90, 92 driven at a slower speed than the rollers 82, 84. The element is guided by rods 86, 88 which extend between grooves in the rollers 82, 84. The adhesive only penetrates the inner ply before setting and maintaining the corrugations in position. The corrugations do not extend to the area adjacent the wire, the material then being crimped or puckered. The corrugated element may be formed in a single annulus to form a buffing section, or be wound into at least two helical coils having an angularly arranged portion 20, Fig. 2, at an area where opposed ends 22, 24, which are preferably tapered, occur. The coils are secured to each other and a central disc 16 of metal or fibrous material by staples 18. A spacing element may be disposed between the coils to increase the axial length of the section, and several sections may be arranged end-to-end to form a buffing roll.

Abstract: 1483801 Semiconductor devices ITT INDUSTRIES Inc 17 Oct 1974 [17 Oct 1973] 45043/74 Heading H1K In a planar diffusion process for making a monolithic I.C. comprising an NPN and a PNP transistor, an epitaxial layer is deposited in two partial layers 11, 12 successively, the upper layer 11 being deposited to such a thickness D that subsequent diffusion treatments leave part of the layer unchanged in conductivity type for a depth corresponding to that of the base zone 2 of the PNP transistor. After deposition of the second partial layer 11 but before diffusion to form emitter zones 7, 8, part 31 of an isolating zone 3 is formed together with a contact zone 41 of the collector of the PNP transistor and a base zone 6 of the NPN transistor. As shown buried zones 5, 5<SP>1</SP> are produced first in a P- type substrate 9 followed by deposition of the first part 12 of the N-type epitaxial layer. Diffusion in this layer produces a sub-collector 42 and a sub-isolating zone 3. There then follows deposition of the second part 11 of the epitaxial layer to the necessary depth D. The emitter 8 may be made at the same time as the collector contact zone 41 in the PNP transistor.

A self cancelling turn-indicator comprises a fixed housing on which are mounted fingers 25,26 spring-urged out of the rotational path of drive elements 34, 35 mounted to rotate with the steering column. Operation of the switch lever 15, rotates ring 13 so that one of the fingers 25, 26 is rotated into the path of the drive elements 34, 35 by an associated stop 36 or 37, mounted on the ring 13, the switch being held in its operated condition by a spring loaded ball 18.

Patent GB-467049-A (GB)
Abstract: 467,049. Electric signalling systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 8, 1936, No. 16019. Convention date, June 6, 1935. [Class 40 (i)] [Also in Group XL] In copying-telegraphy, the light-sensitive cell current is used to charge a condenser, and the charge, on attaining a predetermined value, is used to actuate a keying device and is simultaneously neutralized, thus producing signals of constant amplitude and varying frequency. Current from a cell 1 charges a condenser 5 to a predetermined value sufficient to unblock valve 13. The anode current of valve 13 alters the bias on valve 27 to render it non- conducting and so produce a variation in bias on valves 37, 41 to allow them to become conducting. The current through valve 37 neutralizes the condenser charge, while the current through valve 41 actuates relay 47 to key a transmitter 57. According to the Specification as open to inspection under Sect. 91, the invention is applicable to " counting systems where it is desired to have an indication of units based on the duration of time when light of predetermined or even variable intensity is either revealed to or masked from a suitable light translating element," or may be used as an " illuminationintegrating device," a counter replacing the relay 47 to " give an indication of the number of illumination-time units and bv suitable calibration can be used as an illuminationintegrating meter." This subject-matter does not appear in the Specification as accepted.

Abstract: 1395365 Measurement of optical dichroism VARIAN ASSOCIATES 17 Oct 1972 [27 Oct 1971] 47817/72 Heading G1A [Also in Division G2] In a spectropolarimeter for measuring the linear optical dichroism of a sample 42, i.e. the differential absorbing effect of the sample on two light beams having different planes of polarization 36, 36a, which includes a light source 10, linear polarizer 15 and a first polarizing device 17 which produces elliptically polarized light from the polarized beam 16, a second polarizing device 37 converts the elliptically polarized beam 18 to the two plane polarized components 36, 36a. The first device 17 produces a modulated output of elliptically polarized light, i.e. a beam whose polarization state varies between left and right circularly polarized 20, 20a. Such a beam is used in a conventional apparatus for measuring circular dichroism, where the light path follows the dashed line. Hence the addition of a quarter wave retarder, e.g. a fresnel rhomb, 37 to a known apparatus allows it to be used for linear dichroism measurements. The linearly polarized modulated beam leaving the sample may be converted back to elliptically polarized light before incidence on a photo-tube 23, Fig. 2 (not shown). The photo-tube may be arranged to view fluorescence radiation emitted from the sample 42, Fig.4 (not shown) The order of polarizing elements shown in Fig. 1 may be reversed, Fig. 5 (not shown).

The cylinder space 3 is connected through a conduit 17 to a source of suction when required and through a bore 24 with the bore 20 of the tube 5, which communicates with the recess 9. Resting on the piston 4 when in its initial, upper position is a control piston 8 having a threaded bolt 7 carrying a nut 12 rotatable to adjust the stroke of the piston 8. The bore 20 is connected to atmosphere through bores 21, 22, 23 in the head 6. When a sheet is to be picked up, suction is applied to the conduit 17. Vacuum is produced in the space 3 and owing to the higher pressure in the recess 9 the piston 4 is lowered to the position of Fig. 2 where the head picks up a sheet, while the piston 8 falls until the nut 12 rests on the cylinder 1. Contact with a sheet causes the vacuum to build equally in the space 3 above the piston 4, so that the latter is raised by the spring until it abuts the piston 8, which is held down by suction in the recess 9. The sheet is then fed to the point of utilization by the head and the vacuum then released, whereupon the spring 15 returns both pistons to the position of Fig. 1 before return to a position above the pile.
