Title: Improvements in and relating to machines for excising the corners of rectangular blanks
IPC: B65H7/06
Filed: 1919-10-06
Abstract: 146,757. Alexander, A. E., (Stokes & Smith Co.). Oct. 6, 1919. Tripping and like arrangements.-A machine for cutting out the corners of cardboard and like blanks is provided with a blank-feed stopping device operated from a registering-device when the movement of the latter is fouled by a blank incorrectly positioned under the cutter. The blanks are fed from the bottom of a pile on a table 53 by a reciprocating table 55, an adjustable gate 63 controlling the number of blanks simultaneously fed. Driven rolls 41 then feed the blanks into the cutting position, gauges 67, 68, and a stop 69 serving to position the same. An oscillating finger 73, raised into the path of feed by the weight of its connected parts and lowered therefrom by cam action, normally engages the rear of a blank to ensure the engagement of the blank with the stop 69. Should the finger 73 be unable to rise through a jamming of a blank above it, cam mechanism, normally inoperative, on a shaft 32 is brought into action to raise a stop 83 to prevent further feed of the blank until the obstruction has been removed, whereupon the stop 83 is lowered again by the release by the operator of a spring bolt 91 or the like. A pair of vertical plates serve to counteract any raising of the blank by the finger 73. The feed-table 53 and its associated feed mechanism are all carried by the adjacent carriage 11 so that the desired relationship of parts is not affected by adjustments of the latter.

Filed: 1950-10-11
Abstract: 690,640. Roller-mills. ZUNDAPP-WERKE GES. Oct. 11, 1950 [June 30, 19491, No. 24880/50. Class 59 [Also in Group XXX] A mill for grinding grain and the like between rollers (not shown) has a manually-adjustable device 12 to limit the activity of a feed detector 3 operating a servomotor 9 so that the output of the mill may be limited to less than its maximum. The servomotor 9 controls the starting and stopping of the drive to the rollers, the bringing together and the separation of the rollers, and the flap governing the extent of the gap between a segmental feed gate and a feed roller (not shown) according to the head of grain above the spring-urged detector. Bell-crank levers 6. 8 connected by a link 7 communicate movements of the detector 3 to the servomotor 9, and a chain-drive between a sprocket 20 on the lever 6 and a sprocket 12 on a hollow shaft 17 transmits these movements to a finger 22 on the shaft which co-operates with a scale 24 indicating the setting of the feed gate in terms of output of the mill. A hand-wheel 14 for rendering the servomotor operative also controls it by means of the cam 12 disposed beneath the detector 3 and supported on a shaft 13 carrying the handwheel. A pointer 15 on the shaft 13 indicates the' setting of the cam and therefore the maximum output of the mill at that setting. In the event of the mill operating for a long period at the output corresponding to the setting of the pointer 15, an alarm device (not shown), operating acoustically or optically, functions, indicating that the output of the mill could be increased by further adjustment of the hand-wheel 14. A hand-wheel 10, acting on the servomotor, is provided for adjusting the initial gap between the feed roller and the feed gate to suit the material to be ground.

Abstract: 635,852. Measuring bridges. DENES, P., ANDREW, A. M., and WELWYN ELECTRICAL LABORATORIES, Ltd. Sept. 15, 1947, No. 25168. [Class 37] To determine whether an electrical component (e.g. capacitance, inductance or resistance) lies between pre-determined limits, it is connected in series with a standard component, and these two components are connected in parallel with two pairs of impedances, the ratio of one pair corresponding to the lower limit, and the ratio of the other pair corresponding to the upper limit, and the phase of the voltage at the junction point of each pair is compared. The invention is described with reference to a system for determining whether a resistance 11 falls within pre-determined limits. An A.C. bridge 11, 12, 13, 14 is such that balance is obtained if resistance 11 is at the lower limit and an A.C. bridge 11, 12, 15, 16 is in balance if the resistance 11 is at the upper limit. If the resistance lies between these limits, the phase between 17 and 18 will be opposite to the phase between 17 and 19 and valve 22 will be non-conductive. If the resistance lies beyond these limits, the phase between 17 and 19 and valve 22 will conduct to actuate relay 23 and light signal lamp 24. Signal lamp 25 is lit if the resistance is within the pre-determined limits.

A clutch plate for use in a clutch running immersed in oil is provided with continuous grooves on a friction face, the radial distance of various points on each groove from the centre of rotation of the disc altering according to the angular position on the disc of the point considered. In one form, concentric circular grooves 36, Fig. 2, on one face 34 of a clutch disc 15, are arranged with their common centre offset to the left by an amount a from the centre of rotation of the disc. In. another form, grooves 43, Fig. 5, on the disc face 34 are in the form of ellipses. As a further modification, the grooves can have a wavy shape. The disc 15 shown in Fig. 2 is provided with further similar concentric circular grooves 37 on its reverse face, also disposed eccentrically to the centre of the disc. The centre of the grooves 37 lies on the diameter passing through the centre of the grooves 36 and the centre of rotation and is also a distance a from the latter but is to the right thereof. Elliptical grooves 46, Fig. 5, are provided on the reverse side of the disc 15 to that having the elliptical grooves 43, the major axes of the ellipses 46 coinciding with the minor axes of the grooves 43. The discs may be made from cast iron or medium carbon steel, and can coact with plane clutch discs of bonded asbestos or sintered metal, respectively. The discs 15 are shown used in a multi-disc clutch between a driving flywheel 10, Fig. 1, and a driven shaft 11. A coil spring 26 biases a plate 25 to the right of Fig. 1 to engage with the longer arm of cranked levers 20 pivoted at 21 on a plate 28 secured by rods 19 to the flywheel 10. The cranked levers are thus turned about the pivots 21 so that their shorter arms push at 22 on a presser plate 23 to engage the clutch. A thrust ring 27 is carried by pins 29, passing through holes in the plate 28 and contacting the plate 25. When the thrust ring 11 is moved to the left by the usual linkage (not shown), the thrustof the spring 26 is thus taken away from the cranked levers and the clutch is disengaged.

Title: Improvements in or relating to polymeric compositions containing antioxidants
Inventor: PHILLIPS LESLIE NATHAN
IPC: C08G73/02
Filed: 1963-06-26
Abstract: A polymeric composition comprises a polymeric substance susceptible to oxidation and having incorporated therein a polymeric antioxidant which is a polymer of an aromatic amine with a di(halogenomethyl) aromatic compound having at least two halogenomethyl groups (other than fluormethyl groups) each directly attached to an aromatic nucleus, the polymer being formed by directly linking aromatic nuclei of the aromatic amine to the halogenomethyl groups with elimination of hydrogen halide.  The polymeric antioxidant is particularly useful in compositions comprising a polymeric elastomer, in that the antioxidant also serves to cross-link the elastomer.  In particular polymeric fluoro-substituted hydrocarbon elastomers react with the amine groups of the antioxidant with the elimination of hydrogen fluoride.  Examples describe the cross-linking of a polymer derived from vinylidene fluoride and hexafluoropropylene with a polymeric antioxidant obtained by reacting diphenylamine with p-dichloroxylylene and with a polymeric antioxidant obtained by reacting N,N1-diphenyl-p-diphenylene diamine with p-dichloroxylylene.
