A net of polypropylene having uniaxially drawn ribs connected by undrawn junctures is produced by hot or cold drawing a perforated film. The perforations may be round, eliptical, rectangular with rounded corners, or clover leaflike, and may be produced by punching or, drilling a perforated film or during casting. Drawing may be uniaxially or biaxial. In the latter case, drawing may be effected simultaneously or in series along its longitudinal and transverse axes. The draw ratios in the longitudinal and transverse directions may be the same or different, and may be 1.5-20 to 1. The ratio of widest/narrowest width of rib is preferably equal to the ratio of yield/draw load. Stretching in each direction may be effected in two stages. As shown in Fig. 9, stretching is first effected in direction 47 and then in direction 45 to produce the configuration shown in Fig. 10 with drawn ribs 53 and undrawn junctures 55. An ornamental film may be similarly produced by hot drawing a film having discrete coated areas of heat absorbent material instead of holes and/or complementary areas of heat reflecting material. A second coating step is preferably carried out between longitudinal and transverse stretching.

Title: Improvements in or relating to the injection moulding of brushes
IPC: A46B3/00
Filed: 1951-06-06
Abstract: 708,733. Moulding brushes. SCHIFFER, M., and SCHIFFER, C. June 6, 1951, No. 13451/51. Class 87 (2) The bristles (made of plastic material) are formed into bundles, then the bristles of each bundle are fused together to form heads serving to anchor the bundles in the brush body, then the headed bundles are automatically introduced into the mould cavity, and finally the brush body is moulded in the mould cavity around the said heads. The drawings show injection-moulding apparatus for doing this, comprising a stationary mould half 1 and a movable mould half 2 between which is formed a mould cavity 3 fed with plastic material through bushes 4. The bristles are supplied from bobbins (not shown) and are fed in bundles B through holes 7 formed in two plates 5, 6 and' in mould part 2. Plate 6 is fixed in mould part 2. Plate 5 is movable and is controlled mechanically by the machine or electrically by a magnet, and may be moved to clamp the bundles against plate 6. In operation, starting from the Fig. 1 position in which four brush bodies have been moulded around the heads of the bundles, the mould part 2 opens to the Fig. 4 position through a distance that determines the length of the brush bristles. During this opening movement plate 5 is released from plate 6, and the mould part 2 and plates 5, 6 silde over the bristles. Then the magnet moves plate 5 to clamp the bristles fast, and the mould part 2 opens further (Fig. 5) to pull the brush bodies out of the mould part 1. Four knives 10, heated by plates 8, then move inwards to melt off the bristles embedded in. the brush bodies and to fuse together the ends of the bristles in each bundle projecting from the plates. The mould then closes to the Fig. 1 position, the bristles being pulled from the spools.

Abstract: 273,452. Ross, T. W., and Metropolitan-Vickers Electrical Co., Ltd. May 28, 1926. Electromagnetic switches; cut-out systems.- A relay is provided, in addition to contacts controlled according to the impedance of the line, with a separate set of contacts which are operated by an overload unaccompanied by a drop in voltage. As shown in the Figure an induction disc 10 controlled by a current coil is geared at 14, 16 to a shaft 18 provided with a return spring 20 and a contact arm 42. Mounted coaxially with the shaft 18 and connected thereto by an arm 24 and a spring 22 is a shaft 26 carrying an armature 28 normally held against the poles 30, 32 of a saturated voltage electromagnet and carrying a second contact arm 34. On overload accompanied by a drop in the voltage the rotation of the disc 10 besides stressing the return spring 20 winds up the spring 22 until the attractive force on the armature 28 is overcome when the contact arm 34 is moved over to engage its contacts, the time of operation being a measure of the overload and the fall in voltage, i.e. of the impedance of the line. If no appreciable fall of voltage occurs, however, the attractive force on the armature is not overcome and the contact arm 42 is moved over to engage its fixed contacts in a time inversely proportional to the current. Either or both sets of fixed contacts may be provided with an adjustable setting indicated as by a dial 50. Specification 216,531 is referred to.

Title: Improvements relating to a machine for forming the teeth of a gear
IPC: B23F1/02
Filed: 1945-05-30
Abstract: 593,293. Gear-cutting. HERBERT, Ltd., A., and KELWAY, G. May 30, 1945, No. 13534. [Class 83 (iii)] [Also in Group XXIII] In a machine, or attachment to an existing machine, for rounding the teeth of spur or helical gears by means of a form cutter reciprocated relatively to the gear longitudinally of the teeth thereof, relative reciprocation is also produced in a transverse direction so that the cutter operates more deeply at each end of the longitudinal reciprocations. As applied to a grinding machine, a cutter wheel 15 having a crosssection shaped to the form of the tooth gap is mounted on a slide 13 reciprocated horizontally on the bed 12. The work 17 is carried by a spindle 19 attached to a slide 22 adjustable vertically on a pillar 23 by means of a hand wheel 21 secured to a sleeve 34 which is screwed internally to engage a rod 35 connected to the slide 22. A spring 36 presses the sleeve 34 downwardly so as to cause a collar 40 thereon to bear on a plate 41 through a ball thrust bearing 42, the plate resting on shoes 46 which surround eccentric pins 45 projecting from a trunnion block 47. The latter is pivotally supported on pins 44 carried by brackets 43 on the pillar 23, the axis of the pins 44 being eccentric to that of the pins 45. An arm 33 is attached rigidly to the block 47 and is pivoted to a vertically slidable rod 32 connected by a lever 29, pivoted on the machine frame at 28, to a roller 30 which is maintained by a spring (not shown) in contact with a cam 26 attached to the cutter slide 13. As the latter reciprocates, the cam 26 rocks the lever 29 progressively, first in one direction and then in the other during each working stroke, to oscillate the arm 33 and cause the eccentrics 45 to lower and then raise the work slide 22, thus making the cutter take a deeper cut at each end of the stroke to give the rounding effect to the teeth on the work. The work is indexed after each double reciprocation of the cutter and is fed radially towards the cutter by the hand wheel 21 after each complete revolution until the teeth have been cut to depth. For cutting helical gears, the work is rotated on its axis during machining.

Title: A Fuel Injection System for Internal Combustion Engines
IPC: F02M63/02
Filed: 1968-03-21
Abstract: 1,177,334. Fuel injectors; stopping engines. SOC. DES PROCEDES MODERNES D'INJECTION SOPROMI. March 21, 1968 [March 22, 1967], No. 13648/68. Headings F1B and F1K. In a fuel injector having an electromagnetically operated valve or valves 15, 19, in a return flow line 20 controlling the opening of the ejector valve 10, means are provided either in the fuel supply line 1 or in the return flow line 20 which upon faulty operation of the valve 10 either shut off the fuel flow or actuate an alarm means. In Fig. 1 fuel flows from the pipe 1 to the injector space 10 and supplies fuel flow through orifice 11 to chamber 12A and return pipe 20 via the two electromagnetic valves 15, 19, in series. When valves 15, 19, are closed, the valve 10A is held closed by the pressure in chamber 14, opening of the valves 15, 19, releasing said pressure and permitting valve 10 to open. A pressure gauge 27 is connected to the space 26 between valves 15, 19, and is associated with electrical contacts in an alarm system whereby the alarm is operated when the pressure in space 26 is higher or lower than normal caused by the valves 15, 19, sticking open or not opening. A second safety device 3 in the pipe 1 cuts off the flow to the injector if the valve 10 sticks open. The device 3 comprises a piston 4 by-passed by a passage 6 with a calibrated orifice 6a. Upon normal operation of valve 10 the piston 4 moves by less than its full travel on each injection cycle, the fuel for injection flowing through by-pass 6. If valve 10 sticks open the excessive fuel flow moves valve 4 to its extreme right position, blocking by-pass 6 and cutting off the fuel flow. The by-pass 6 may be replaced by an orifice through the piston. Valve 15 may be arranged to open slightly before valve 19, the resultant slight reduction in pressure in chamber 14 permitting valve 10 to open briefly for a pre-injection. In a modification Fig.2 (not shown) the device 3 is replaced by a spring-loaded piston (24) carrying electrical contacts which close upon an abnormal pressure drop in chamber (23) to actuate an alarm and cut off the fuel flow.

Filed: 1962-04-09
Abstract: 1,008,789. Electro photographic processes. MINNESOTA MINING and MANUFACTURING CO. April 9, 1962 [April 7, 1961], No. 13662/62. Heading G2H [Also in Division H1] Colour xerographic plates consisting of a conductive substrate carrying a regular or random pattern of minute photoconductive areas coloured cyan, yellow and magenta and selectivity sensitive to red,green and blue light respectively (see Division H1) are exposed and developed in the following manner. The coloured image to be reproduced is formed on the plate or projected on it through red, blue and green filters in turn. To develop the resulting conductivity image the plate may be placed in an electrolyte containing a suspension or emulsion of positively or negatively charged resin particles which, if not inherently white, contain white inorganic pigments such as titanium dioxide and zinc sulphide. Suitable resins are polymers of fatty acids and polyamines, copolymers of vinyl chloride and vinyl acetate, polyvinylacetate, silicones, and epoxy resins all of which are positively charged in emulsion or suspension and nylon, polyethylene, chlorinated rubber, polybutadiene, styrene-butadiene copolymers, and acrylic polymers and copolymers which are negatively charged. With the conductive support as anode or cathode as the case may be electrolysis results in deposition of the resin on the areas rendered conductive by exposure to the light to which they are sensitive. An alternative procedure is to develop the image cathodically in an aqueous solution of silver sulphate or copper sulphate to deposit metal before developing as described above. If suitable e.g. certain triphenylmethane and azo dyes are used as colourants these may be bleached out by electrolytic treatment in aqueous ethyl alcohol containing zinc chloride. A further alternative is to place the plate in a corona discharge into which white particles are sprayed. After development in any of these ways in the red areas of the image for instance, the cyan coloured photoconductive areas are covered or bleached out leaving only magenta and yellow coloured areas giving the effect of dull red, and so on. The image may be brightened by heating, or moistening the plate with a solvent for the dyes to locally intermingle the remaining colours. To produce a charge image which may be electrostatically developed the plate is either uniformly charged before exposure, or is subsequently charged through the conductivity pattern. The resulting image is developed by positively or negatively charged white resin particles. For example a developer consisting of a powder of polyvinyl chloride pigmented with titanium dioxide and mixed with powdered alumina to increase its fluidity is flowed over the plate in a tray, the image fixed by heating and a protective layer of wax or lacquer applied if desired. If the lacquer contains a suitable solvent this also causes local mixing of the colours, thus rendering a separate treatment for this purpose unnecessary.

Abstract: 514,502. Winches STANCLIFFE, C. W., and WINGET, Ltd. May 7, 1938, No. 13701. [Class 78 (v)] The winding drum 6 of a hoist is journalled freely on a continuously rotating power shaft 1 and is coupled thereto at will by an expanding spring coil 11. The coil 11 surrounds the shaft 1 and lies within a sleeve 8 held non-rotatably relative to the drum 6 by teeth 9, 10. 'One end of the coil 11 engages an abutment 12 on the shaft 1 and its other end abuts against a stop 13 on a drum 14 frictionally mounted on the shaft 1. Normally the shaft 1 pulls the coil 11 tightly around it, both coil 11 and the drum 14 rotating with the shaft. By tightening a brake band 15 around the drum 14, however, the latter is retarded and the coil 11 expands to bear against the inner face of the sleeve 8 and rotates same together with the drum 6. To prevent the load unwinding the cable 16 from the drum 6 when the latter is not being driven a self-sustaining device is provided comprising a spring coil 23 attached at one end 24 to an extension 21 of the drum 6, the coil 23 lying closely within a drum 18 loose on the shaft 1 and provided with a brake band 20. When the drum 18 is held stationary by the band 20 rotation of the drum 6 in the unwinding direction tends to expand the coil 23 and prevent further motion of the drum 6. Fig. 2 -shows an arrangement whereby both drums 14 and 18 can be operated from a single control lever 39, which is connected by a shaft 38 to a cross bar 37. One end of the bar 37 bears on the free end of a 'lever 32 pivoted at 33 to release the drum 18, and the other end of the bar bears on the free end of a lever 26 pivoted at 25 to apply the band 15 to the drum 14. Thus rocking of the arm, 39 one way allows the drum 6 to unwind and the other way couples the drum 6 to the shaft 1. An extension 40 on the lever 39 lies in the path of the load at its topmost position, thus automatically disconnecting the drive from the winch drum and preventing application thereof till the load is lowered. The device is stated to be applicable to concrete mixers and like machines,.the pinion 5 shown being for the purpose of rotating the mixing drum.
