Title: Improvements in or relating to slice moulding and wrapping machines for semi-pasty substances
IPC: A01J27/00
Filed: 1960-06-27
Abstract: 901,127. Wrapping-machines. KUSTNER FBERES ET CIE S.A. June 27, 1960 [July 1, 1959], No. 22467/60. Class 94(1). A machine for wrapping plastic material such as cheese encloses increments in plastic form between opposed heat sealable webs, the sealing of the webs about each increment being accompanied by shaping of the increment. The cheese is extruded from a nozzle 7 on to a web 2 and is drawn by intermittent movement beneath the second web 9, the guide roll 11 of which may flatten each increment. The nozzle may move relative to the web to deposit cheese when the web is stationary. The roll 11 may also reciprocate horizontally to slacken the web during sealing. The webs are forced together on the support 1 by a frame 21 in a descending head 12, and a plate 23 within the frame then presses the enclosed cheese so that it fills completely the space available and expels air through apertures 28 in the frame. Further descent of the head causes a heated member 25 to seal the webs together. The resulting string of packages is drawn forward by a reciprocating plate 18 and a finger 17 which may have perforating or severing means for dividing individual packages. A conveyer belt may replace the support 1, the belt having the advantage of cooling during its lower run.  The cheese may be irradiated on the web 2 to destroy mould, spores, &c. A series of joined packages may be folded to zig-zag form.

Title: Polymerization of episulfides and new episulfide polymers
IPC: C08G75/08
Filed: 1965-05-26
Abstract: Polymers of epithiurane compounds, including crystalline polymers having an inherent viscosity of at least 0.5, are prepared by polymerizing the episulphide(s) alone, or with an epoxide using as catalyst the reaction product of a halogen-free organomagnesium compound with a polyreactive compound, which is (1) a compound containing at least two groups of active hydrogen, C=O, N=O, S=O, P=O, C=S, P=S, C­N, N=S, (2) a compound containing -N = N- or (3) CO or NO.  The organomagnesium compound is preferably of the formula RR1Mg, where R is any hydrocarbon; R1 is R or H, OR, NR2 or SR. Typical polyreactive compounds are those having at least two active hydrogen atoms, e.g. water, polyhydric phenols, ammonia, amines, aminoalcohols, hydroxylamine, hydrazine, hydrogen sulphide, sulphoxides, dialkyl sulphides, acids, ketones, esters and nitriles; or compounds with at least one active hydrogen and at least one of C = O, N = O, S = O, P = O, C = S, P = S, N = N, C­N, e.g. benzoic acid, nitrosophenol, and HCN; or compounds containing at least two C = O, N = O, S = O, P = O, C = S, P = S, C­N or N = S groups and no active hydrogen, e.g. CO2, NO2, SO2, P2O5, C.S2, N4S4, (CN)2; and the compounds CO and NO. Suitable episulphides include those of formula <FORM:1107158/C3/1> wherein R, R1, R11 and R111 are hydrogen, or unsubstituted, halo-, alkoxy- or aryloxy-substituted hydrocarbon radicals such as alkyl, alkenyl, aryl, cycloalkyl, cycloalkenyl, haloalkyl, alkoxy methyl or aryloxy methyl; when R and R111 are both hydrogen, R1 and R11 can together form a cycloaliphatic ring. Suitable epoxides include alkylene oxides. The polymers may be formed into films, fibres and moulded articles, and may be stabilized or treated with other conventional additives.  In examples (1)-(3) a catalyst is prepared from diethyl magnesium and (1) water, (2) ammonia, and (3) resorcinol. In the remaining examples, propylenesulphide cis-2-butenesulphide, trans-2-butene sulphide, isobutylene sulphide and ethylene sulphide are homopolymerized using the catalysts from Examples (1-3).  In Example (26), the catalyst of Example (2) was used to prepare a copolymer of ethylene-sulphide and ethylene oxide.

Title: A new or improved device for screw and bolt driving and nut running
IPC: B25B23/14
Filed: 1938-07-28
Abstract: 516,904. Screwing-up nuts &c. GWATKIN, F. A. S. (Black & Decker Manufacturing Co.). July 28, 1938, No. 22526. [Class 83 (iii)] In a portable, power-driven manually operable tool for driving or running nuts, bolts &c. the tool shaft is driven through an epicyclic gear comprising planetary pinions on a carrier which may be held stationary to drive the tool or may be allowed to rotate to enable the tool to remain stationary, means being provided for adjusting minutely the pressure with which the carrier is held stationary to determine the torque at which slip takes place. In one form the shaft of an electric motor 3 carries a pinion 6 engaging two gears 8, 9, attached to shafts 10, 11 rotatable in a carrier 15 and carrying pinions 19, 20 which engage a gear 21. The boss of the gear 21 is provided with a shank 30 rotatably supported within the tool spindle 32 and carries a transverse key 41 engageable with clutch teeth 40 on the spindle when the tool is pressed against the nut &c. to be tightened, but normally kept apart therefrom by a spring 35. A thrust bearing 28 for the gear 21 is held in the gear casing 1 by a washer 27<1> and screw 27. The motor 3 may operate through reversing gearing for. screwing up or unscrewing and for either operations rotation of the'carrier 15 is prevented by a surrounding sleeve 16 split axially at 45 and contracted on to the carrier by a block 47 having a wedge-shaped groove engaging' axially tapered flanges at the sides of the split 45. The block engages a recess 47<1> in the casing 1 to prevent rotation of the sleeve 16 and may be moved axially, to vary torque at which the carrier may slip when the nut &c. is set, by means of a screw 50 and lock nut 53. When the carrier slips it rotates and allows the pinions to roll round the gear 21 without driving the tool, until the motor is stopped or the clutch 40, 41 disengaged by withdrawing the tool from the nut &c. being operated upon. An extension 22<1> of the shank 30 is rotatably mounted in the carrier. 15 and the motor casing 2 is provided with a pistol-grip handle and a switch. A shroud 37 for the tool spindle and chuck is attached to the bearing bush 36 for the spindle: In a modified construction wherein tangential hammer-blows may be imparted to the tool the carrier 111, Fig. 11, is not split and is prevented from rotating by a pivoted pawl 132 engaging a bevelled recess 131 therein. The pawl is pivoted to the gear casing 101 at 133 and is pressed into contact with the carrier by an adjustable spring 134. When the nut &c. is set the pawl is cammed out of the recess 131 and rotation of the tool is stopped until the carrier has made one revolution and the pawl drops into the recess again, thereby delivering a rotational blow to the tool.

Title: Improvements relating to winder and haulage equipment
Inventor: STUBBS GEORGE HENRY
IPC: H02P5/46
Filed: 1965-05-27
Abstract: 1,147,063. Electro-physical measurement control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 18, 1966 [May 27, 1965], No. 22602/65. Heading G1N. [ Also in Divisions G4 and H3] The angular position of a winch or winding drum of winding or haulage equipment is controlled in accordance with the phase difference between an A.C. signal produced in dependence on the position of the winch or drum and a reference A.C. signal. The rotor of a transmitter Selsyn ST1, Fig. 1, whose single phase winding is connected to an A.C. supply, is mechanically connected to the winder drum and electrically, through switch S1, to a receiver Selsyn SR1, whose rotor is positioned at the required angular position of the drum. The output from Selsyn SR1, whose amplitude and phase sense represents the instantaneous difference in position of the rotors of the two Selsyns, is fed to a phase sensitive rectifier, Fig.2 (not shown), (see also Division H3), whose D.C. output, in magnitude and polarity, depends on the amplitude and phase sense of the input to the rectifier and therefore on the relative shaft position. This signal is passed through a shaping circuit, Fig. 4 (not shown), (see also Division G4), to a circuit which controls the drive to the drum. The speed and direction of drive depends on the amplitude and polarity of the signal from the shaping circuit. For haulage and winding equipment in which the winder drum is arranged to stop at various positions, the transmitter Selsyn is connected, via switches S1, S3-S5, to one of a number of receiver Selsyns SR1-SR3, one for each stopping position. The operation of the switches may be manual, the switches being operated in conjunction with the winder driver's control levers, semi-automatic, when the switches are controlled from level selection circuitry controlled from selection push buttons at control stations, or fully automatic, when the switches are set automatically for the next stopping position when one stopping position is arrived at. For a winder with two independent drums each is provided with a transmitter Selsyn ST1, ST2 and each is connected to the main drive-shaft by a clutch to permit independent movement. A position error detector, Fig. 7 (not shown), (see also Division H3), for supervising stopping at each station, is provided in the circuit, which detects the magnitude of the error voltage and, when this is very small, causes the removal of power from the winder and control circuits and the application of the winder brake.

Title: Vehicle speed-boosting apparatus
Inventor: WILSON WILLIAM GEOFFREY JOHN
IPC: F15B21/00
Filed: 1965-05-31
Abstract: 1,073,788. Propelling vehicles. WESTING- HOUSE BRAKE & SIGNAL CO Ltd. May 18, 1966 [May 31, 1965], No. 23021/65. Heading B7L.  Apparatus for boosting the speed of a vehicle when its speed is below a predetermined value comprises a cylinder 1 having a high pressure inlet 2 and outlet 3, the outer end 5 of a piston 4 within the cylinder being formed with a depression engageable by a lever (not shown) which is contacted by the vehicle wheel to force the piston down at a speed dependent on the speed of the vehicle, the arrangement being such that if the vehicle speed is below the predetermined value a hollow stem 13 carried by the piston 4 operates a valve to allow fluid pressure from the inlet 2 to exert a force on the piston forcing it up and speeding up the vehicle via the lever, and if the vehicle speed is above the predetermined value the stem 13 collapses on engagement with the inlet valve whereby it is not opened. The piston 4 has a wall 6 extending across it forming volumes 8 and 9 connected by an aperture 7 In the wall. Carried by the wall sub-cylinder 10 which defines a cavity 11 within which slides a sub-piston 12 which carries the hollow stem 13. A spring 14 within the cavity biases the stem out of the cylinder 10 and acts through a plate 15 on a ball valve 16 permitting entry only of fluid to the cavity 11. Extending from the cavity 11 through the wall 6 is a conduit 17, 18 which is normally closed by a second piston 20 slidable within piston 4 and defining with wall 6 the volume 9. The piston 20 is urged by a spring 21 to close the conduit. The valve operating the inlet 2 comprises a sleeve 26 slidable over a core 27 and the inlet comprises an axial conduit 29 and radial passages 30 formed in the core. The sleeve has two stable positions determined by detent means 33 constituted by balls urged resiliently radially outwards to engage either a groove 32 as shown, whereby the inlet is closed and the outlet open, or a groove 34 whereby the inlet is open and the outlet closed by a sleeve 35 connected to sleeve 26. A plate-like member 40 is urged towards the open end of the sleeve 26 by a spring 41. A slow running vehicle will cause piston 4 to move down cylinder 1 and stem 13 to contact plate 40 which after compression of spring 41 will cause the detent means to operate and the sleeve 26 to move down and open the inlet, at the same time closing the outlet. High pressure fluid entering the cylinder 1 will cause the piston 4 to move up and accelerate the vehicle via the lever. Contact at 42, 43 between piston 4 and sleeve 26 will cause the sleeve to move up and the apparatus to return to its original state. A fast-running vehicle will cause piston 4 to move fast such that a pressure will build up within cylinder 1 and piston 20 will lift off wall 6 opening conduit 17, 18. The stem 13 will then collapse into cavity 11 as it contacts plate 40 and the inlet valve will not open. The low pressure permitted through outlet 3 will return piston 4 after the vehicle has passed.
