Title: Improvements in air line lubricators
IPC: B25D17/26
Filed: 1954-08-24
Abstract: 753,964. Lubricating. JAMES, G. E., REES, W. J. C., LANGDON, A. B., and DARBY, V. E. Aug. 24, 1954 [Jan. 30, 1954], No. 24644/54. Class 12 (3). An air line grease lubricator comprises a pipe 4 having a constriction 5 in the bore shaped to form a non-streamlined abutment, a balance hole 7 and a grease inlet orifice 8 in closer proximity to the abutment than the balance hole 7, a jacket 9 around the pipe providing a grease reservoir.

Title: Process for the manufacture of adipic acid
Inventor: BRIERLEY CHARLES
IPC: C07C45/83
Filed: 1960-07-15
Abstract: In a process for the manufacture of adipic acid by oxidizing cyclohexane under pressure and in the liquid phase at elevated temperature with an oxygen-containing gas and then oxidizing the product with nitric acid after stripping out cyclohexane, the product of the first oxidation is introduced without preliminary injection of water into the cyclohexane stripper by means of a let-down valve at 140 DEG C. or more, preferably 145 DEG  to 155 DEG C., and at a pressure greater than that in the stripper.  The pressure in the stripper may be atmospheric or lower.  The temperature and quantity of steam introduced in the stripper may be adjusted to obtain a stripped residue having a water content of 8 to 15% by weight.  The stripped residue may be steam distilled and the steam volatile fraction oxidized to adipic acid with nitric acid, or the steam volatile fraction may be washed with aqueous alkali and water before nitric acid oxidation.  Examples are given. Specification 633,354 is referred to.

Abstract: 408,144. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Sept. 6, 1933, No. 24726. Convention date, Sept. 8, 1932. [Class 38 (iii).] Regenerative and non - regenerative braking.-In a system for the regenerative, and short-circuit braking of series motors, a motorgenerator provides for external excitation of the motor fields, in addition to their self-excitation, and a relay which connects the fields for external excitation, simultaneously short-circuits a resistance arranged for damping the first regenerative impulse. After a period of short-circuit braking of motors a, b, contacts h, p, are closed, the former making the supply connections, and the latter energizing a time relay q. After an adjustable time contacts r, s, of the relay q, are closed, the former shortcircuiting a resistance w which damps the first regenerative impulse, and the latter connecting an exciting generator g to the motor fields c, d. Contacts u, v, of the relay q are also operated to interrupt or weaken the selfexcitation of the fields. At the end of the regenerative braking range, the contacts h, p, may be opened, and the relay q de-energized, so that short-circuit braking is again effected. The contacts r, s, u, v, are arranged to be temporarily closed simultaneously when the relay q is operated to ensure that the field excitation is maintained. The generator g is driven by a motor u, and has a field i adjusted by resistance m, and opposing a field k in the motor circuit. The resistance m may be adjusted by the braking current and potential.

An expiring roll 6, Figs. 1, 2 and 3, of paper or like web and a replacement roll 7 are carried on shafts 4, 5 rotatable by a yoke 3 about a pivot 2. The roll 7 has temporarily attached thereto by hooks 21 and springs 20 a roller 18 pressing against its surface behind the adhesivecoated leading edge portion 17. The pivot is rotated to bring the roll 7 into position to press the running web against a roller 12, Fig. 2, the roll 7 being retained in its original angular aspect. When the roll 6 has almost expired, a brake for the shaft 5 is released, and the running web accelerates the roll 7 until the latter and the running web are moving at the same speed, when the roller 12 presses the adhesive-coated portion against the running web for splicing, Fig. 3. The roller 18 presses the running web against a knife 13 to be severed, and the abutment of the roller 18 against the knife cause the hooks to come off the shaft 5 and the roller 18 and its assembly to fall into a receptacle 16.

Filed: 1920-08-31
Abstract: 150,704. Kauffmann, H., and Kiesel & Co., O. Sept. 1, 1919, [Convention date]. Ploughs.-A motor-plough comprises a tractor frame, supported on two front driving-wheels and a rear steering-wheel, and a plough frame B attached to and drawn by the tractor through a vertically adjustable coupling C. The land wheel is provided with deep oblique ribs so that the tractor frame may be maintained practically horizontal whether travelling on a road or across the field with the furrow-wheel in a furrow. The coupling C is adjusted vertically by a lever or by a nut 11 riding on a hand-operated screw I, the nut being connected to the coupling C by a link I2. A cord I3 passes from the nut over pulleys on the frame to the rear of the plough frame so that when the coupling C is raised considerably the rear of the plough frame is lifted from the ground, thus enabling the machine to be turned. The ploughs are maintained in position by a guiding-frame F pivoted to the tractor frame and engaged by hooks G1, G2 on the plough beams. One pivot of the frame F is vertically adjustable, and the rear of this frame is provided with pedals F1, F2 so that the driver can press on the plough frame as needed. The entire transmission gear with the motor is arranged in a common frame. To enable the machine to be turned sharply a hand-operated brake may be applied to the driving-wheel at one side. Specification 106,829 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also states that the motor drives the main wheels through a differential gearing operating pinions d and h in opposite directions, these pinions meshing with external and internal gear-wheels respectively on the driving-wheels. The tractive forces imparted to the two driving wheels may be different. This subject-matter does not appear in the Specification as accepted.
