Title: Reinforced polymers and process of producing same
IPC: C08K5/54
Filed: 1963-03-07
Abstract: A shaped article is prepared by combining a filler or reinforcing element and a polymeric mix comprising a normally liquid polymer prepared from 75 to 100% of a C4 to C6 conjugated diolefin and 25 to 0% of a monovinyl monomer and curing the combination at a temperature of from 330 DEG  to 550 DEG  F. in the presence of a polyperoxide catalyst having a half-life of at least 2 minutes at 300 DEG  F.  The filler may be a silica (precipitated, ground or quartz), clay, alumina or calcium carbonate.  The reinforcing element may be glass fibre, asbestos, mica, vegetable fibre, silk, hair, nylon, or a metallic material such as iron, aluminium or copper.  The exemplified peroxides are 2,5-dimethyl-2,5-di-(t - butylperoxy) - hexane, 2,5 - dimethyl - 2,5 - di - (t - butylperoxy) - hexyne, di - t - butyldiperoxyphthalate or 2,5 - dimethylhexane-2,5-di-(peroxybenzoate). The liquid polymer may be mixed with rubbers, such as natural rubber, butyl rubber, or SBR, or polymers such as polyethylene, polypropylene, EPR, or polyisobutylene. The mix may contain up to 2% of a polymerizable monomer, e.g. vinyl tris-(2-methoxyethoxy)-silane or diethylamino-ethyl methacrylate as a size for the glass fibre or to aid dispersion of the filler.  Small amounts of solvent may be used for the same purpose.ALSO:A glass fibre reinforcement is coated with a composition comprising a normally liquid copolymer prepared from 75 to 100% of a conjugated diene and 25 to 0% of a monovinyl compound and a polyperoxide catalyst which has a half-life of at least 2 minutes at 300 DEG F.  The assembly is then cured at a temperature of from 330 to 550 DEG F.  Peroxides specified are 2, 5-dimethyl-2, 5-di(t-butylperoxy)-hexane, 2, 5-dimethyl-2, 5-di(t-butylperoxy)-hexane, di-t-butyl diperoxyphthalate, and 2, 5-dimethylhexane-2, 5-di(peroxy-benzoate.  The mix may also contain other polymeric ingredients, e.g. natural rubber, butyl rubber, SBR, polyethylene, polypropylene, ethylene-propylene rubber, or polyisoeutylene.  The mix may also contain a small proportion of a polymerizable monomer such as vinyl tris(2-methoxyethoxy) silane and diethyl-aminoethyl methacrylate. The glass fibre may also be treated with an unsaturated silane monomer.  The composition may contain fillers, e.g. silica, chalk, whiting and alumina, and antioxidants, e.g. di-t-butyl p-cresol.

Patent GB-980631-A (GB)
Title: Improvements in or relating to voltage stabilisation circuits
Inventor: GASKILL CHARLES DAVID SINCLAIR
IPC: H02M3/156
Filed: 1960-03-16
Abstract: 980,631. Automatic voltage control. INDUSTRIAL PROCESSES Ltd. June 1, 1961 [March 16, 1960], No.9266/60. Heading G3R. A load R L  is supplied from a voltage stabilizer which includes a switch SW in series with a capacitor C in parallel with the load, the arrangement being such that when the capacitor has been charged to a value slightly higher than a pre-set value E a control circuit opens the switch so that the capacitor discharges to supply the load; when the voltage across the discharging capacitor falls to a value slightly less than E the control circuit closes the switch. The voltage across the capacitor is thus a direct voltage of a value E with a superimposed ripple which is smoothed out by a conventional series type voltage stabilizer. As shown in Fig. 2, a transistor T1 corresponds to switch SW and capacitor C1 to C of Fig. 1. Transistor T1 is controlled by an emitter follower T2, a Schmitt trigger T3-T4, and another emitter follower T5. The base of T2 is fed from a tapping on a potentiometer R3-4-5 connected across C1 and thus receives a voltage proportional to that across C1. The emitter supply voltage of T2 is  fixed by a Zener diode Z1, so that the voltage. applied to the base of transistor T3 is proportional to the difference between the actual voltage  across C1 and the desired voltage E. When the actual voltage exceeds the desired voltage by a  predetermined amount T3 switches off and T4 switches on; T5 is thus driven positive and T1 is cut off. The voltage across C1 then falls as the capacitor supplies the load;T3 conducts when the voltage has fallen a predetermined amount and T1 is thereby switched on again via the transistors T2-T5. A convention-- al series-transistor type stabilizer, shown in the chain dotted box, smoothes out the ripple in the voltage across capacitor C1. A modification  including protection against short-circuit and voltage surge conditions is described with reference to Fig. 3 (not shown). Two switching transistors in parallel may be used (Fig. 4, not shown).

Title: Improvements relating to cloth stentering machines
Inventor: BECK EDWARD GEORGE ANDERSON
IPC: D06C3/00
Filed: 1953-04-07
Abstract: 733,256. Stentering-machines. MATHER & PLATT, Ltd. March 26, 1954 [April 7, 1953], No. 9350/53. Class 42 (1). A cloth stentering machine disposed in a heatinsulating enclosure f has the gearing and mechanism which effect adjustment of the width of the stenter rails c placed outside the enclosure, with connections, in the form of push-pull rods d, e, from the gearing and mechanism to the rails passing through holes in the enclosure wall; the mechanism is thus kept free of deposit of resins &c. used in the treatment of the cloth. As shown, rods d, e, connected to the rails c, pass through the stenter enclosing wall f and are threaded to engage nuts i, j fixed to sleeves k, m which are turned in unison but in opposite directions by gears n and are driven by a shaft o connected by a clutch and worm gearing to a motor-driven shaft r which also actuates other pairs of push-pull rods arranged along the length of the machine. When the clutch is engaged, shaft o is rotated by shaft r; when the clutch is disengaged, shaft o can be rotated by means of a hand-wheel s. In a modification, shaft o drives, through wormgearing, a pinion meshing with racks fixed to rods d, e.

Title: Improvements in or relating to muting devices for radio receivers
IPC: H03G3/26
Filed: 1933-03-28
Abstract: 413,443. Valve circuits for wireless reception. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SMYTH, C. N., c/o General Electric Co., Ltd., Wembley, Middlesex. March 28, 1933, No. 9351. [Class 40 (v).] When signals below a predetermined threshold value are being received a blocking bias is applied to the signal rectifier and to the grid of a valve amplifying the D.C. gain control potentials. As shown, the signal rectifier is one of the diodes 4, 3 of a double-diode triode valve 5, with a load resistance 6, the D.C. and A.C. potentials across which are applied separately to the triode grid. The low frequency output from valve 5 is taken from the transformer 7 associated with its plate circuit. Potentials for the automatic gain control of other valves in the circuit are taken from a lead 8 being derived after D.C. amplification in the triode 5 from the cathode resistance 25. The control is applied through and delayed by the diode 9, 3 the anode of which is biassed through resistance 28 from the portion 21 of a potentiometer 19-24. The muting valve 13 is a double diode triode the two diode anodes being connected together and fed from a tuned circuit 10. The load resistance 14 of this diode circuit is also in the triode grid circuit 16 together with an adjustable biassing voltage taken through the leads 15 from a tapping on the main supply potentiometer, while the triode plate circuit 17 includes the resistance 6. When signals below a predetermined intensity are being received, the valve 13 passes a large plate current through the resistance 6, thus blocking the signal diode 4, 3 and the grid of the triode 5. When the signal increases, the voltage across the resistance 14 increases, blocking the grid 16 and removing the blocking potential across resistance 6, which further results in increased amplification of the controlled stages and thus increases the rapidity of the change from the inoperative to the operative state and vice versa.

Title: Improved fine adjustment means in or for height gauges and similar linear-dimension measuring instruments
IPC: G01B5/06
Filed: 1954-03-31
Abstract: 752,926. Linear-dimension gauges. GREY RUSHTON (PRECISION TOOLS), Ltd., and GREY, V. H. June 18, 1954 [March 31, 1954; May 17, 1954], Nos. 9367/54 and 14336/54. Class 106 (2). [Also in Group XXIII] Fine adjustment between two slides 4, 5 on a column 2 of a height gauge is effected by rotating an adjustment member 22 about an axis at right angles to the direction of relative movement of the slides. As shown in Figs. 4, 7, a disc is turned by a knob 22 rotatable in the slide 5 so that a spiral slot 24 of regular pitch formed on the disc engages a lug 25 projecting from a depending reduced portion of the slide 4. As shown in Fig. 8 the knob 22 turns a bevel gear 34 to rotate a nut 36 integral with a bevel gear 35. The nut 36 is prevented from axial movement and so drives axially a threaded rod 37 secured to the slide 4. As shown in Figs. 12, 13, the knob 22 rotates through a reduction gear train 49, 50, 52, an eccentric pin 45 engaging a hole in a shoe 47 slidable in a transverse slot 46 in the slide 4. The slide 4 is suitably guided in the slide 5 for relative sliding by pin and slot means, grooves or flanges. The slide 5 may be locked after fine adjustment by a clamping screw 18 and the slide 4 is locked preferably by one of the means described in Specification 752,927. In each embodiment the fine adjustment means effectively connect the slide 5 to the slide 4 for movement therewith during coarse adjustment.

Title: Improvements in or relating to terminal connections of secondary batteries
IPC: H01M50/553
Filed: 1944-05-16
Abstract: 576,866. Galvanic batteries ; mounting terminals. VARLEY DRY ACCUMULATORS, Ltd., and LARK, H. D. May 16, 1944, No. 9399. [Classes 38 (i) and 53] An accumulator is provided with a terminal pillar extension which extends through a wall of the container and terminates flush with the outer surface of the wall. A flexible connector may be connected to the exposed surface of the terminal pillar extension. The connections within the accumulator are embedded in pitch or other material to protect them from acid. Fig. 3 shows a member 17 which is welded to the terminal pillar to form an extension which passes through the side wall 10 of an accumulator. The member 17 is provided with a flat head 21 the outer surface of which is flush with the outer surface of the container. The head 21 is cylindrical in shape and fits into a correspondingly shaped recess in the wall 10, the body portion of the member 17 and the opening in the wall 10 through which it passes being of rectangular shape to prevent turning. Fig. 3 shows one method of connecting a flexible conductor 22 in which the bared ends 32 of the strands are embedded in the member 17 during the casting of the latter. A portion of the insulation 31 may also be embedded to strengthen the joint. The head 21 may be formed with a slot 33 so that if the conductor becomes detached or broken an emergency repair can be made by soldering the conductor in the slot. Fig. 4 shows a modified method of making the connection in which a screw-threaded socket 34 is embedded in the member 17 and receives a screwed plug secured to the end of the conductor 22. Fig. 5 shows a further modification in which the conductor is fitted with a head 39 which enters the socket 34 and is clamped in position by a screw-threaded sleeve 38. The accumulator fitted with the terminal connector described above may comprise positive and negative pasted plates separated by porous insulating material containing the electrolyte, the whole forming a pack which must be compressed before it can be inserted in the casing.

Title: Improvements in machines for severing webs
IPC: B26D1/24
Filed: 1943-06-11
Abstract: 557,962 Severing webs by burning. TRIGGS, W. W. (Cameron Machine Co.). June 11, 1943, No. 9439. [Class 31 (i)] In a machine, which is especially applicable for severing webs composed of organic derivatives of cellulose into strips by means of heated knife-edged discs 2, the discs 2 are so arranged that the operation can be seen by the operator, and the discs 2 are heated by the burners 11 when the discs are moyed out of operation so that when severing is resumed the discs are ready for immediate action. The web W is fed from a roll 3 and is pressed against a roller 1 by spring-pressed rollers 45, the cut strips being wound upon a spindle 4 driven by friction at a speed adapted to maintain the strips taut. The discs 2 are mounted in lever arms 5 formed at their ends with springs 7 for connection to rods 9 operated by levers controlled by a pedal 15. The burners 11 are also mounted in levers 13 operated from the pedal 15, and when the pedal is depressed a catch 32 holds the discs 2 and burners in operative position. A chain 36 also operated by the pedal 15 controls a clutch for starting and stopping the drive of the roller 1 and spindle 4. When the discs 2 are moved away from the roller, drive of the roller ceases, so that, on resumption of the drive, the severing recommences at the position where it ceased. The burners 11 are fitted with a protecting cowl 12, and when raised out of operative position the discs 2 are rotated by an auxiliary driver 33 which continues in operation when the main clutch is thrown out. The roller 1 may be watercooled.

Title: Carton Erecting Apparatus.
Inventor: TLY ROBERT KENNEDY GELLA
IPC: B31B5/80
Filed: 1968-02-28
Abstract: 1,176,103. Erecting cartons. FMC CORP. 28 Feb., 1968 [9 March, 1967], No. 9541/68. Heading B8C. Collapsed cartons C are releasably retained in a magazine 32, Fig. 10, whose wall 62 is adjustable to accommodate different size cartons, by a discharge window 40. The foremost carton C is pulled past the window 40 by a pivoted suction head 42, Fig. 19, and an overbend bar 212 overbends the carton to break the creases on an overbend plate 50. Whilst the carton C is pulled past the window 40, a projection 45 engages a tab 158 on the rear panel 46 of the carton to open it progressively from the bottom closure end BC to the top closure TC. The projection 45, as a result of the progressive opening of the carton C, causes the lower edge 48 of the carton to be inclined downwardly along its length less than 5 degrees to the horizontal. The overbend plate 50 is similarly inclined. The suction head 42 is pivoted on a shaft 184, Fig. 12, which is connected to a bellcrank 186, itself pivoted on a shaft 188. The bell-crank 186 is also pivoted, by means of an arm 192, to a pin 194, eccentrically mounted on a cam disc 196. A roller 204, which is journalled to a bell-crank 200, slides in a cam track 206, the other end of the bell-crank 200 being pivoted to a link 208, itself pivoted to the bell-crank 186. Movement of the bell-crank 186 causes the suction head 42, and hence the overbend bar 212, to rotate clockwise about shafts 184, 188 so effecting the breaking of the carton's creases on the overbend bar 50, Fig. 19. The magazine 32, Fig. 2, comprises a fixed wall 56 and the adjustable wall 62 which is slidable upon a fixed rod 66 and a lower rotatable rod 68 having four longitudinally spaced grooves (not shown) to engage the wall 62. The rod 68 is rotated by an indexable locking device 38 which allows the wall 62 to engage a selected groove for a selected carton size. A pusher 94, which may be latched in its upper position by a handle 101, as shown, to enable carton stacking, slides down the magazine on guide rods 96 which are secured to carriages 98, 100, themselves slidable on the rods 66, 68. To enable the pusher 94 to be retained midway between the walls 56, 62 when adjusting the wall 62, screws 110, 110a rotatable by a crank 112, have portions 114 with twice the pitch of portions 113. A break away device 140, Fig. 10, has a rotatable carton arresting bar 146 held by spring-loaded detents 154. Should a carton be accidentally returned to the window 40 by the suction head 42, the carton merely engages the bar 146 and overcomes the holding force of the detents 154, causing the bar to swing clockwise, so avoiding breakage of the windows 40 or the suction head 42.
