Title: Improvements in full-fashioned stocking and method of producing the same
IPC: A41B11/00
Filed: 1945-11-27
Abstract: 608,768. Knitting. DEHN, S. G. (Wytheville Knitting Mills, Inc.). Nov. 27, 1945, No. 32026. [Class 74(ii)] The heel portion of of a flat knit single unit stocking includes narrowing lines 24 commencing near the selvedge and running at an acute angle to it, the lines being formed by transferring greater numbers of loops on successive courses. All the narrowing may be performed in this manner, or narrowing may be interrupted at 25 and resumed at 25' by transferring equal numbers of loops on alternate courses only, thus producing a fashion line parallel to the selvedge.

Abstract: 1473899 Drop dispensing apparatus SHOCK V AUTOMATIC LUBRICATION SYSTEMS Inc 19 July 1974 [26 July 1973] 32115/74 Heading B8N [Also in Division F2] Apparatus for dispensing controlled small quantities of a liquid, e.g. a suspension type lubricant, from a supply comprises liquid circulating means, valved dispensing outlet means in the circulating means, including a discharge conduit of capillary size, and valve opening and closing control means operably associated with the valved dispensing outlet means and capable of momentary opening of the dispensing outlet means and subsequent rapid closing to apply momentary shock impetus to the liquid in the dispensing outlet means for controlled liquid ejection through the capillary conduit. As described lubricant L, Fig. 1, is circulated by a pump 28 through conduits 32b, 32b<SP>1</SP> control valves 16, 16<SP>1</SP> and conduits 44<SP>1</SP>, 44. Each valve, e.g. 16<SP>1</SP>, Fig. 3, comprises a plunger 64 having a valve element 64<SP>1</SP> urged against a valve seat 78 by a spring 80 and a solenoid coil 62 which when activated raises the plunger. The plunger 64 has axial passageways 64a and a central passageway 70 connected thereto, and the valve housing includes an inlet 88, an outlet 72, and an outlet port 86 communicating with capillary tubes 100. In operation lubricant is continuously circulated through inlet 88, passageways 64a, 70, and outlet 72. When the coil 62 is activated for a few milliseconds by current supplied via an electric switch and timer device the valve is opened and lubricant enters the port 86. The shock created when the valve recloses causes a controlled amount of liquid to be discharged from the free ends of the tubes 100, e.g. on to a conveyer system 18, Fig. 1.

Title: A commutator winding for multi-phase commutator machines
IPC: H02K27/02
Filed: 1947-12-05
Abstract: 643,753. Winding layouts for dynamo. electric machines. MORAVIAN ELECTRICAL ENGINEERING WORKS, NATIONAL CORPORATION, and KILMA, V. Dec. 5, 1947, No. 32155. Convention date, Dec. 5, 1946. [Class 35] A commutator winding for a polyphase A.C. machine is fed by brushes at 2m points per pole pair where the number of slots is 4m per pole pair, m being an integer greater than two (usually three), and the feeding points are unsymmetrically spaced from each other because out of 4m regularly distributed feeding points half are omitted, i.e. only one of each pair of diametrically arranged feeding points is fed. The number of feeding points can be further increased if the winding is subdivided into two parallel windings, e.g. one a lap winding and the other a wave winding, with the same number of parallel branches each connected to the segments and having a pitch which is shortened or extended by an odd number of slots so that the conductors of the two coils lie in four slots. As shown, the regularly distributed feeding points 1, 2... 12, are only fed at points 1, 2, 5, 6, 9, 10 through a secondary winding X, Y, Z. The coils b, c (lap) and d, a (wave) are short pitched by one slot but modifications are shown in which they are shortpitched by three or five slots. If a multiple parallel winding is used an additional auxiliary wave or lap winding having a pitch of about <SP>1</SP>/ 3  pole-pitch is also wound into the slots and connected to the commutator segments. It is stated that half of the armature coils (laps and waves alternately), may be omitted, so that there are only two conductors attached to each segment, without impairing the function of the machine. The winding may be energized by two sets of brushes as above, the sets being joined through stator windings so that speed regulation may be obtained by shifting the brushes so as to alter their relative positions on the commutator:

Title: Synchronous self-shifting clutches

Abstract: 1,136,138. Ratchet clutches. S.S.S. PATENTS Ltd. 7 July, 1967 [20 July, 1966; 24 Aug., 1966], Nos. 32577/66 and 38022/66. Heading F2C. A synchronous self-shifting clutch comprising two rotary members, an intermediate sleeve splined to one of said members and carrying clutch teeth engageable with clutch teeth on the other of said members, and pawls on either the intermediate sleeve or said other member which engage ratchet teeth on the other member or the sleeve when the rotary members reach synchronism to initiate clutch engagement, has the engaging surfaces of the pawls and ratchet teeth inclined relative to the clutch axis so that the contact forces between them have an axial component to move the sleeve for clutch engagement, and as the clutch teeth approach full driving engagement their interaction disengages the pawls from the ratchet teeth. In Fig. 1, the ratchet teeth 5 have a helix angle of 35 degrees and the clutch teeth 2, 12 have a helix angle of 30 degrees, straight splines 9, 10 connecting the sleeve 11 to the input member 7. When the input member 7 reaches the speed of the output shaft 1, pawls 3 engage ratchet teeth 5 on the sleeve 11, causing the sleeve to be moved leftwards so that teeth 12 thereon move between teeth 2 on the shaft 1. Because of the different helix angles, as the sleeve moves leftwards, the teeth 12 engage the teeth 2 to generate an axial force urging the sleeve leftwards, and continued movement causes the pawls to move out of engagement with the ratchet teeth, so that on full clutch engagement, all the load is transmitted by the clutch teeth 2, 12. In a modification, the splines 9, 10 may be helical to assist clutch engagement. In Fig. 2, the clutch teeth 25 and the ratchet teeth 27 on a shaft 15 are combined as at 18, the clutch teeth 25 and clutch teeth 23 on the intermediate sleeve 22 being straight, while the ratchet teeth 27 and the faces 28 of pawls 24 have a helix angle of 10 degrees in the opposite sense to the helical splines 20, 21 between the sleeve 22 and the shaft 19. Thus as shaft 15 starts to drive shaft 19, both sets of helical surfaces urge the sleeve leftwards. In Fig. 3, clutch teeth 43 with a helix angle 30 degrees are combined with ratchet teeth 45 with a helix angle 35 degrees, as at 34, the intermediate sleeve being connected to its shaft by straight splines.

[Class 40 (ii).] A sound record and a picture record are photographed on the same negative film without regard to the relative degrees of blackening of the two records and a duplicate sound-record negative having the desired degree of blackening is then produced from the original sound negative. Finally, a combined sound and picture-positive film record is printed from the picture part of the original negative and the duplicate sound-record negative. The duplicate sound negative may be produced by means of an electrical re-recording apparatus, or by a photo-chemical process, or by a double copying operation. The picture and sound recordings may be copied separately on to the positive film or the printing of the positive film can be effected in one operation. In the latter case the duplicate sound negative may be joined to the original sound-and-picture negative and the picture film printed in one operation by the contact process. The Specification as open to inspection under Sect. 91 (3) (a) states also that the original sound and picture records may be photographed upon separate negative films and, after the production of a duplicate sound record, the printing is effected upon a combined sound-andpicture positive film. This subject-matter does not appear in the Specification as accepted.
