Title: Improvements in and relating to fasteners
Inventor: FERNBERG ERIC BIRGER
IPC: F16B12/46
Filed: 1959-11-27
Abstract: 908,357. Dowel pins. F.T. PRODUCTS Ltd. Nov. 17, 1960 [Nov. 27, 1959; Feb. 29, 1960; April 4, 1960], Nos. 40471/59, 7069/60 and 11864/60. Class 89 (2). In an assembly of a fastener 10 and two members 24, 25 held together thereby, the fastener 10 has a head 13 having means for attaching it to the member 25 and a tail 12 formed with at least one tongue 14 having its free end directed out of the general plane of the tail 12 towards the head 13, the member 24 being formed with an undercut groove opening into an edge of the member 25, the tail 12 being engaged in the groove 26 with the tongue 14 preventing withdrawal. In one form (Fig. 3) the members 24, 25 consist of two flat co-planar panels, the head 13 being co-planar with and similar to the tail 12, tongues 14, 15, 16 and 17 in the head 13 and tail 12 pointing in opposite directions, whereas each panel has a groove 26, 28, the head 13 engaging in the groove in the panel 25 and the tail 12 in the groove in the other panel 24. The edges 22 and 23 may be bent upwardly away from prongs 18, 19 and 20, 21 formed from the bent tongue ends, to facilitate assembly. The members may be two flat panels lying in perpendicular planes with adjacent edges, a fastener 31 (Fig. 5) having a flat head 32 perpendicular to the tail 31 and engaging a face of one panel, the tail 31 being engaged in the groove in the other panel. In another form the members consist of two slotted beadings 44, 45 (Fig. 8) with their ends adjacent at 43 and their longitudinal axes inclined obliquely, the fastener shown at 40 having a head 42 coplanar with and similar to the tail 41, opposed tongues in each being directed parallel with the axes, respectively, the head 42 and the tail 41 engaging in beadings 44, 45. The undercut groove in the member may be of dove-tail crosssection, the tail being of shape and size substantially to fit the groove, which may be shallow and stopped and formed by two overhanging ribs lying one on either side of it. In the form shown in Figs. 10 and 12, to hold panels 55, 56, the head 52 is bent into a plane perpendicular to that of the tail 51 and has a threaded aperture 53, the fastener 50 having one or two stiffening depressions 54. Fig. 13 shows a similar fastener 60 except that prongs 61 and 62 are cut from the edges of the tail 63 instead of from within it. To be able to withdraw any assembled fastener from a groove it is given square-nosed bent spring tongues instead of prongs. The fasteners are mainly for use with panels of synthetic plastic material. The groove may be a rectangular closed or overhanging slot or dove-tailed (Fig. 19). With very thin panels two ribs 70, 71, inclined to one another and stopped short of the panel edge form the overhang of a dove-tail to give a shallower groove.

Abstract: 1,064,718. Spinning acrylonitrile polymers. MONSANTO CO. Oct. 16, 1963 [Oct. 16, 1962], No. 40890/63. Heading B5B. Continuous filaments are made from acrylonitrile polymers by extruding a solution of acrylonitrile polymer through a spinneret immersed in a coagulation bath comprising a solvent for the polymer and a non-solvent therefor; subjecting the filaments to a stretch of 2-50 times in the coagulation bath; removing the filaments from the bath; subjecting the filaments to an additional stretch ratio of 1À14-6À14 times in air and taking up the filaments at a final take-up speed of 200-1000 metres per minute. The acrylonitrile polymer may be a homopolymer, copolymer or polymer blend containing at least 80% by weight of acrylonitrile. Subsequent to the stretching in air, the filaments may be further stretched in liquid or gas in a plurality of stages to a total stretch ratio, including the air stretch, of 2-10 times. Prior to final take up, the filaments may be subjected to shrinkage in steam at 100- 140‹ C. The coagulation bath may be maintained at 0-50‹ C., and may consist of a polymer solvent (many specified) and at least one miscible non-solvent comprising water, aromatic hydrocarbons, alcohols, polyalcohols or halogenated hydrocarbons. In examples, filaments are wet-spun by extruding solutions of acrylonitrile polymers in dimethylacetamide or dimethylformamide into coagulation baths consisting of spinning solvent and water, butyl alcohol, ethylene glycol, xylene or trichloroethylene. Spinning conditions are such that coagulation is slow and filaments of fine denier are produced.

Title: Method of monitoring a toner mix
IPC: G03G15/08
Filed: 1972-09-04
Abstract: 1398964 Developing electrostatic latent images; automatic control of concentration EASTMAN KODAK CO 4 Sept 1972 [ 3 Sept 1971] 40984/72 Headings G2H and G3R The concentration of toner particles in a carrier/toner developer mixture applied to electrostatic latent images on a photo-conductive belt 2 by a magnetic brush 31 is monitored by measuring the potential on the brush when the brush is in contact with charge-free portions of the belt between successive charge-bearing images. A toner replenisher 47 is actuated whenever the potential on the brush, which rises with depletion of toner, exceeds a predetermined value. Preferably the periodically obtained potential values are applied as input pulses to an integrating amplifier 55, and the replenisher is actuated when the accumulated output of the integrating amplifier reaches a threshold value within a time set by a counter 56. If the accumulated output does not reach the threshold within the time set, the counter returns the integrating amplifier and itself to zero, and actuation of the replenisher has the same effect.

Abstract: 1478559 Data recording system INTERNATIONAL BUSINESS MACHINES CORP 10 Oct 1975 [25 Nov 1974] 41558/75 Heading G3N A control system controls movement of a sensor head 104 across a record medium, e.g. a magnetic tape or a flexible magnetic disc 100. The head 104 is moved from its current position to a desired position by entering a desired track number in register 152 from control unit 150, comparing it in unit 158 with the present track count in counter 156, and using the difference to energize stepping motor 116, which controls head movement, via counter 226. When an error occurs, e.g. cessation of power supply 202, control unit 150 detects an error, or a lid is opened, the motor moves the head to the edge of the disc beyond a reference track 134 outside the data tracks 135. When this point is reached, a switch 136 is actuated by movement of carriage 106 and the head is moved back to the reference track. When a maximum amplitude is found by detector 142, due to passage over the reference track, the counter 156 contents are reset to zero and all the data tracks within the reference track are counted from this zero count to compensate for any changes in the disc size due to temperature, wear or disc replacement. The reference track may be inside the data tracks in another embodiment.

In an embodiment, Fig. 5, the cathode comprises a metal electrode 13 and a body 31 of P type semi-conductor material, preferably of germanium or silicon, the switch also including an amorphous body 11, and a metal electrode 12. Upon the application of a known voltage to the anode and cathode of the device, electrons, the minority carriers of the body 31, are supplied to the amorphous material 11, but these are not in sufficient numbers to initiate switching as would be the case were a plain metal anode and cathode used. The presence of the body 31 requires a higher voltage to be used to initiate switching. If the polarity of the voltage is reversed then the known voltage is sufficient to cause switching since it is holes, the majority carriers of the body 31 which are then supplied to the body 11. An asymmetrical device is thus produced.  In further embodiments, the semi-conductor body may form part of the anode, in which case it is N type, or both anode and cathode may include semi-conductor bodies. An alternative embodiment includes an injection contact 52 on the semi-conductor body 51, the contact being connected to its associated electrode 13 via a bias voltage 55 and a signal transducer 54. By varying the signal value to the contact 52 the value of the threshold voltage may be varied.  The threshold voltage may also be varied by applying light of a wavelength to which the semi-conductor body is opaque to the body, or alternatively the body may be transparent to the wavelength, in which case the amorphous body is activated by the light. The semiconductor material may be amorphous or crystalline. Specifications 1,070,411 and 1,070,412 are referred to.
