May 11, 1936, No. 13865/35. [Class 102 (i)] In lubricating or other apparatus, of the type in which liquid is distributed to a number of points by a rotary distributer 2, the casing 1 is attached to a plate 10, to which the lubricating pipes 11 are connected. A pump plunger 30, reciprocating in a central bore in the valve 2, draws liquid from a space 15, supplied by a pipe 16, and discharges it past a piston or other valve 27 to passages 23, 24 supplying ports 25, 26. The latter register in succession with passages 18, 19, arranged in two rows, and communicating with the pipes 11, which are arranged in concentric circles. The plunger 30 is operated by a lever 7, 31, mounted on a spindle 6, and connected to a piston 9 in a cylinder 8, which is connected to a source of suction. The stroke of the piston 9 is regulated by means of a screw stop 38. The valve 2 is rotated by means of a ring 42, carrying a pawl 44 which engages a ratchet wheel 43 on the valve. The ring 42 has a fork which is engaged by a finger 41 on the spindle 6. The positions of rest of the valve can be adjusted by means of a stud 37 forming a stop for the lever 7.

IPC: D01G11/04
Filed: 1921-05-19
Abstract: 184,867. Johansen, O. May 19, 1921. Openers; feeding openers.-In a machine for making fibrous waste from rags &c. the material is carried by an endless belt 11 to serrated feedrolls 6, 7 which deliver it to a small picking- drum 5, whence it passes to a large picking-drum 3 and is severed into single threads. The rolls 6, 7 have grooves engaged by combs 29, 38, the comb 29 forming an extension of a basket 26 having slots for the passage of the pins 50 on the drum 5. The material is pressed against the basket 26 by a spring-supported slotted grid' 32 and passes over a shoe 40 provided with grooves for the pins of the small drum. The grid 32 is carried on pivoted arms 37 so that it can be swung away when a pivoted support 34 is turned down. The drum 5 is engaged by a clearing-comb 18 carried by spring-pressed arms 17. The casing surrounding the large drum 3 has a lining 41 formed with grooves for the pins 4. The main shaft 43 carries a brake disc 42 adapted to be engaged by a shoe 41<a> on a weighted lever 44 engaging a crank 46 on a cross shaft 47 which operates bevel gearing 48, 49 so as to shift the belt fork lever 52. A handle 59, which is connected to an arm 58 on the shaft 47 by a link 58<a>, normally engages a notch 60, Fig. 5, but is released therefrom, if the small arm becomes clogged, so that it is moved to the position shown in dotted lines by the lever 44 and the driving-belt is shifted on to the loose pulley. The handle 59 is released by a lever 61 connected to a driving-sleeve 63, which is splined on the shaft 64 of the picking-drum 5 and is connected to the driving-wheel by a tooth 65 so that it is moved longitudinally if the rotation of the shaft is hindered'. Before starting the machine, the shaft 64 is turned by a hand-wheel 69 until the tooth 65 again engages its recess.

Title: Improvements in height and range finding devices
IPC: F21L4/08
Filed: 1937-05-21
Abstract: 484,255. Range finders. GRANAT, E., and COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT. May 21, 1937, No. 14241. Convention date, May 25, 1936. [Class 97 (i)] Electrical apparatus for obtaining the height or range of an object from data obtained by observing-instruments at the ends of a base, comprises resistances which are varied according to appropriate functions of the data, a function represented by the current through a resistance being directly multiplied by a function represented by the current through another resistance by passing the currents through separate windings of a galvanometer &c. Fig. 2 shows apparatus for obtaining the height H of an object from the azimuth angles alpha, #, Fig. 1, measured from the ends A, B of a base of length b, and the angle of elevation # measured at A. In this case the height H is given by H< >=b tan #/ (1/tanalpha + 1/tan#) Sin alpha. A rheostat 1, supplied from the mains, is controlled by the azimuth of the telescope at B and is so designed that the current i1 through the rheostat varies as 1/tan #. Another rheostat 2, in parallel with the rheostat 1, is similarly controlled from the telescope at B so as to produce a current i2 varying as 1 /tan alpha. A third rheostat 3, in parallel with the rheostats 1, 2, is controlled in accordance with the angle of elevation of the telescope at A so as to produce a current i3 proportional to 1/b tan a. A further rheostat 4 is fed from the rheostat 3 by a tapping on the wire 5 and is so designed that when its slide is controlled in accordance with the angle alpha a current proportional to (1-Sin alpha/b tan a is obtained in the rheostat. To prevent variations in the resistance of the rheostat 4 from affecting the value of the current in the rheostat 3 a compensating rheostat 6 is provided, this rheostat being controlled by a slider integral with that of the rheostat 4 and being so designed that the resistance of the circuit comprising the rheostats 4, 6 and the galvanometer &c. I remains constant. The current i4 in the wire 5 is thus proportional to i3 Sin alpha, i.e. to Sin alpha/b tan #. The galvanometer has two stationary windings through which the currents i1, i2 pass, and a movable winding receiving the current i4, so that the deflection is proportional to i4 (il + i2), i.e. to 1 /H. An arrangement for obtaining the horizontal range of the object from one end of the base is also described. The observing instrument at one end of the base may be replaced by a searchlight to enable the object to be observed from the other end of the base to be clearly identified.

Title: A method of and apparatus for continuously indicating the thickness of a moving fibrous web
Inventor: BRERETON KENNETH GEORGE ORWELL
IPC: G01B7/06
Filed: 1954-05-17
Abstract: 772,739. Electric correspondence control systems. BRITTAINS, Ltd. May 17, 1955 [May 17, 1954], No. 14454/54. Class 40 (1). [Also in Group XXXVI] In a method of determining the thickness of a fibrous web a controlled discharge is caused to pass through the air spaces in the web and the voltage required to initiate such discharge is measured. The air spaces approximate in length to the thickness of the web so that measuring the D.C. or A.C. voltage required to produce ionization of the air in the air spaces indicates the thickness of the web. In Fig. 1 a continuously moving paper web W passes between and in contact with electrode rollers E1, E2 and a capacitor C charges through resistor R1 and discharges through current limiting resistor R2 and the air spaces or channels in the paper web W in contact with electrodes E1, E2. The ionization voltage across web W as measured on voltmeter V continuously indicates the thickness of web W at a known apparent density. The roller E2 is earthed and rotates about a fixed axis and roller E1 has an adjustable position and is connected to the negative side of the D.C. voltage applied to C/R1. The electrodes may be of semiconducting material, or may be constructed of metal with a continuous surface or a surface interrupted with insulating segments. A bridge circuit utilizing an instrument recording the thickness is described, Fig. 3 (not shown).
