Filed: 1929-03-01
Abstract: 330,238. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). March 1, 1929. Stationary-cutter machines. - The lining 110, Fig. 6, at the top of a boot upper 112 is cut away on the bevel at a lower level than the top of the upper so as to be concealed thereby. The layers stitched together at 114 are placed between a spring-urged pressure roller and the fixed work support and clamped by raising trigger 146, the curve 134 of the upper being received in the notch 132 of a guide 28, a fin 136 on the guide locating itself in the crease between the sewing 114 and the free edges of upper 112 and the lining 110 to deflect the lining 110 under the smooth " lead in " 126 of a movable shearing edge 122. The work is fed forward intermittently bv a toothed feed bar 44 with known 4-way motion, and cutting takes place during the return of the feed-bar by the cutting edge 122 which moves from right to left, Fig. 4, shearing taking place against the fixed shearing edge 104 and edge 122. The cutter remains in its cut and move back with the work as it is fed forward bv the next stroke of the feed bar, the cutter being arranged to partake of the same horizontal movments as the feed bar but not the vertical one. The cutter 42 with its cutting edge 122 is clamped on the bevel to a tool holder 96 which in turn is mounted on the cam operated feed carriage 54. The pointed blade 120 of the cutter runs in the crease of the layers as above, the top of the blade being smooth to slip under the upper layer of the work. A shoulder 106 is formed at the top of the stationary shearing edge to assist in holding the work against the spring pressure roller 26 during cutting. When trigger 146 is raised it allows spring 144 to drop presser wheel 26 on the work and also allows spring 138 to drop guide 28 into position, abutments 152 providing interrelated action but a tolerance is allowed between the abutments so that when presser 26 is raised with the work by the feed bar 44, it does not lift the guide 28 with it.

Title: Substituted succinimides
IPC: C07D207/40
Filed: 1951-03-21
Abstract: The invention comprises N-methyl-a -phenyl succinimide and N-allyl-a -phenyl succinimide.  They are prepared by reacting a -phenyl succinic acid or the anhydride thereof with methylamine or allylamine, and heating the resulting reaction product.  When the acid is used the intermediate product is the di-salt of the acid and the amine; from the anhydride the intermediate is the half amide, i.e. the corresponding b -N-methyl or allyl-phenyl succinamic acid. The half amide upon heating, preferably in the presence of a dehydrating agent, e.g. acetyl chloride or acetic anhydride is converted into the corresponding substituted succinimide.  In examples: (1) N-methyl-a -phenyl succinimide is obtained by (a) reacting phenylsuccinic acid and methylamine to give b -N-methyl succinamic acid, which is then heated with acetyl chloride to give the imide; (b) phenyl succinic acid and methylamine solution are mixed, and excess water is removed from the resultant salt, which is then heated to 200-250 DEG  C. to yield the amide; (2) phenylsuccinic anhydride is reacted with allyl amine to give b -N-allyl phenylsuccinamic acid which is heated with acetyl chloride to give N-allyl-a -phenylsuccinimide.  A table shows the anti-convulsant effect on cats and mice of the products.

Abstract: 633,753. Automatic temperature control systems. LANDIS & GYR SOC. ANON. Nov. 23, 1945, No. 6798/49. Convention date, Nov. 25, 1944. Divided out of 633,689. [Class 38 (iv)] In a temperature-sensitive regulating system an inductive device, the armature of which is subject to the action of an expansion system, is connected in an electrically-balanced circuit with at least one other inductive device to control a receiver such as a regulating instrument. In Fig. 1, deviations of temperature are detected by relative expansion of a tube 5 and rod 6 adjusting the position of a magnetic shunt 4 to alter the voltage induced in the secondary winding 11 of an inductive device 1, the primary winding 9 of which is supplied from A.C. mains a, b. A further inductive device 2, the magnetic shunt 7 of which is adjustable manually by a knob 8, has its primary 10 energized in series with primary 9, and its secondary 12 connected in antiphase to secondary 11 in a circuit including current coils 14, 15 of a Ferraris disc relay 3 having a voltage coil 13. The arrangement is such that deviation of temperature from a value determined by the setting of knob 8 results in unbalance of the secondary voltages of the inductive devices 1, 2 to energize coils 14, 15 and move the Ferraris disc in such a direction that a contact 16 engages the appropriate contact 17 or 18 to energize an electrical circuit effecting temperature correction. The arrangement of Fig. 2 differs in that, on temperature deviation, a bridge circuit formed by the primary and secondary windings of the inductive devices is unbalanced to energize coils 14, 15. Fig. 3 shows a modified inductive device in which a core 4 is adjustable along the axis of a fixed secondary winding 11 by temperature-sensitive means or manually. Alternatively core 4 may be fixed and winding 11 adjustable along it. Fig. 4 shows an inductive device in which a core 4 and secondary winding 11 are rotatable. Connection of an amplifier to increase sensitivity is referred to. Specification 609,484 is referred to.

Title: Gyromagnetic Resonance Spectrometer having Selectable Internal and External Resonant Control Groups
Inventor: NELSON FORREST ARTHUR
IPC: G01R33/46
Filed: 1967-02-13
Abstract: 1,170, 523. Gyromagnetic spectrometers. VARIAN ASSOCIATES. Feb, 13, 1967 [Feb. 21, 1966], No.6825/67. Heading G1N. In a gyromagnetic side-band resonance spectrometer, in which the applied R.F. or D.C. fields are audio frequency modulated, the resonance condition of the spectrometer is controlled using either an "internal" or "external" reference sample, both being provided. By "internal" is meant a reference sample situated in the same field as the sample under investigation and by "external" a reference sample situated in a different field. The internal reference sample may be intermixed with the sample or may be contained in one chamber of a vial 3, Fig. 2 (not shown), having coaxial chambers or an axial or transverse partition providing the two chambers. It is preferably formed of a substance, e.g. the protons in tetramethylsilane, having a narrow resonance line. The external control sample (13, Fig. 2 not shown), is placed to one side of the internal sample and is surrounded by coaxial coils (14), whose axis is parallel to the D.C. field direction, by which this field may be locally altered. It is preferably composed of the protons in water, having a wide resonance line. In operation, the output of either the internal or external reference sample is fed to an oscilloscope 57, Fig. 3 on which it can be seen whether it is in resonance or not, and to a phase detector 54, the output of which, representative of the dispersion mode resonance signal, is fed to a control 55 by which the D.C. field is regulated to maintain the resonance condition of the spectrometer. Initially the current in the coils (14) is adjusted until the frequencies of resonance of the two reference samples coincide so that, in switching between the two reference samples, the control of the D.C. field is not altered. Thus while the internal reference sample is being removed with the sample under investigation and another sample put in its place, the D.C. field is automatically controlled by the external reference sample, the more exact control provided by the internal reference sample taking effect as soon as the system is switched over without the need to relocate its resonance line.
