Abstract: 451,467. Shoe stiffeners. HAUPT, R., Albersweiler, Pfalz, Germany. Aug. 21, 1935, No. 23527. Convention date, Nov. 3, 1934. [Class 17 (ii)] [See also Group VIII] A material for shoe stiffeners is prepared by impregnating a hair, paper, or wool felt with a solution of an artificial resin, such as a phenol formaldehyde resin, allowing the felt to dry, and then impregnating it with a solution of a mixture of nitrocellulose and artificial resin. The initial impregnant may contain a small amount of nitrocellulose, and the final impregnant may include plasticizers and fillers. The stiffeners are softened by a solvent, such as acetone, before being pressed between a shoe upper and lining. The Specification as open to inspection under Sect. 91 describes also the use of an unfulled felt and the omission of the preliminary impregnation with artificial resin, and a method of lasting shoes with the use of these stiffeners in which rapid drying of the stiffener is obtained by the use of heated grippers or a blast of hot air. This subject-matter does not appear in the Specification as accepted.

Title: Method of Determining the Focussing Error of Optical Instruments
Inventor: ATKINSON MALCOLM
IPC: G02B27/40
Filed: 1966-05-26
Abstract: 1,199,142. Photo-electric automatic focusing. STEEL CO. OF WALES Ltd. Aug. 7, 1967 [May 26, 1966], No.23662/66. Heading G1A. In an optical instrument such as a microscope having an illuminating system, the focusing error, that is the displacement of an object from the object plane of the instrument, is determined by sensing the illumination in a plane in the illuminating system and conjugate to the object plane so that as the image of the object goes out of focus in this image plane due to displacement of the object, the level of illumination changes. Fig. 1 shows a compound microscope with a mirror 10 as an object and an illuminating system 13 with a field stop 16. A photo-cell, mounted in an eyepiece or upon a screen is positioned in the conjugate plane B with the field stop 16 either just within the aperture of the field stop or just without, so that as the size of the image of the object changes due to the object moving the illumination of the photo-cell changes. The field stop may be positioned before or after plane B so that the direction of the displacement of the object can be ascertained from whether the illumination of the photo-cell rises or falls. However with the field stop at B two photo-cells may be present so that as the focusing changes their illumination changes in opposite senses; this avoids the influence of light source variations. The two photo-cells may alternatively be placed behind a mask which has two additional apertures to correspond with two small apertures upon opposite sides of a diaphram in another conjugate plane. One aperture of the diaphram is infront of the conjugate plane and the other behind so that when the object is in focus neither aperture is in focus upon the respective of photo-cell, but as the object goes out of focus one or the other aperture comes into focus raising the illumination of the associated photo-cell.

Title: Knitting machine controller
Inventor: WARREN GEORGE

Filed: 1960-07-07
Abstract: 919,723. Knitting machines. BENDIX ERICSSON U.K. Ltd. June 22, 1961 [July 7, 1960], No. 23752/60. Drawings to Specification. Class 74 (2). [Also in Group XXXVIII] The pattern of a knitting machine is controlled either manually, or by a punched card or tape or magnetic tape which contains information as to the number of fashions to be performed, the number of courses to be knitted between successive fashions, whether the fashion is an increase or a decrease and the number of stitches concerned. The two latter items control the machine in an unspecified manner. The numbers of courses and of fashions, in binary code are read and stored on sets of bi-stable transistor pairs. Pulses from cam-shaft-contacts cause the stored number of courses to be reduced by one as each course is knitted. When the number has been reduced to one, a coincidence gate is prepared so that when the last programmed course is knitted a relay is operated to initiate a fashions operation. This in turn reduces the stored number of fashions by one, and causes the programmed number of courses to be re-entered in the store. This sequence continues until the fashions number has been reduced to one, when a second coincidence gate is prepared so that after the last fashions operation, a card rack solenoid is operated to advance the programme card and so provide the information for the next set of operations.

Abstract: 1357893 Machine supports HAWTHORN LESLIE (ENG) Ltd 13 Aug 1971 [19 May 1970] 24074/70 Heading F2X A machine is secured to a fixed support or foundation 7, 11 by means of a plurality of devices each comprising lower and upper plates 1, 2 having parallel rectilinear corrugations and with a layer 3 of deformable material located between them. By causing the layer 3 to adhere to the plates, it may often be employed without any further restraint in the vertical direction. When large separating forces are involved, however, connecting means are necessary and in one example bolts 4 extend through holes 5 in the lower plate 1 in a tight fit and through corresponding holes 5 in the upper plate 2 in a loose fit to allow the upper plate 2 to move relative to the lower plate 1 in the direction of the corrugations, the bolts 4 (only one shown) being secured to a plate 8, spaced from an upper flange 9 on the machine by a layer of resilient material, and to the foundation 7, 11. The upper plate 2 fits into a recess in a lower flange 6 on the machine and the lower plate 1 rests on the foundation member 7. The bolts 4 have sufficient flexibility to take up any relative lateral movement due to thermal expansion between the machine and the foundation. The holes 5 in the lower and upper plates 1, 2 may be of the same diameter with the bolts 4 having a portion of reduced diameter where they pass through the upper plate 2 (as shown), or the bolts 4 could be of uniform diameter with the holes in the upper plate 2 larger than those in the lower plate 1. One of the devices is introduced at each support point requiring a degree of horizontal flexibility and oriented so that the axis of its corrugations lies along the local direction of thermal expansion. The corrugation axes of the various devices should all coincide at a common point which will be the position where the machine remains stationary relative to the foundation.
