Abstract: 671,196. Supporting bearings. SPINDEL-, MOTORENUND MASCHINEN - FABRIK AKT.-GES. July 13, 1950 [July 14, 1949], No. 17594/50. Class 12 (i). A journal bearing for spinning and twisting spindles, has sleeves which are disposed between the journal casing and journal bushing so as to dampen the oscillations which occur during operation of the spindle. A spindle 3 in a journal bushing 2 is suspended within the journal casing 1; between the bushing 2 and the casing 1 are disposed three cylindrical sleeves 7, 8, 9 having curved bottom portions 71, 81, 91. The convexities of the portions 7<SP>1</SP>, 8<SP>1</SP>, 9<SP>1</SP> progressively decrease from the innermost to the outermost sleeve, while at the same time the diameters of the sleeves 7, 8, 9 are in such proportion that the play between each pair of sleeves increases from inner pair to outer pair. Holes and passages 5, 6, 7<SP>11</SP>, 8<SP>11</SP>, 9<SP>11</SP> interconnect the various parts, and the casing 1 contains oil which serves to dampen the oscillations of the spindle 3. In operation, the oil is in continuous circulation and is thereby always being cooled. In a modification, the sleeves 7, 8, 9 have cone-shape bottom portions. A form of the device is also described in which the sleeves 7, 8, 9 are simple cylinders without curved bottom portions.

Title: Methods of manufacturing tubular printed circuit armatures
IPC: H02K3/26
Filed: 1971-05-28
Abstract: 1315273 Printed circuit armatures INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [26 Aug 1970] 17820/71 Heading H1R A method of manufacturing a tubular printed circuit armature comprises the steps of preparing at least two laminated cards and placing the cards about a mandrel (Fig. 4, not shown) in such a way that the cards form a double thickness at their central portions and a single thickness at their edges, the edges meeting to form an axial seam in the resulting tube. The cards comprise a flexible insulating layer 11, e.g. of glass fibre and an etched, possibly photoetched, conductive layer 10 forming the armature winding conductors 14. The cards may be formed from laminated stock as illustrated in Figs. 1, and 2 (not shown), the stock having apertures or being arranged so that areas of conductive layer 10 are not covered by insulating layer 11, enabling the two cards to be electrically joined, the stock illustrated in Fig. 2 being used in the present embodiment. The edges of the flat cards are trimmed as shown and thermally activated adhesive is placed on the insulating layer 11 of at least one card, the conductive terminal portions 17, 18 being masked from the adhesive. The top card is then placed on the bottom card in the position indicated in dotted outline, the terminal portions 17, 18 of at least one of the cards possibly having been coated with solder. Holes 20 are provided for the purpose of alignment and engage pins (22) (Fig. 4, not shown) in the mandrel. The cards and mandrel are then placed in a shell (23) and the jig so formed is subjected to an elevated temperature, the mandrel and shell being arranged to have different temperature coefficients of expansion. Thus at the elevated temperature the cards are forced together and the glue activated. Additionally, the solder, if present, is melted so that the cards are electrically connected. The resulting tubular assembly is then masked except at one end of the conductor, and the assembly placed in an electroplating bath to form a raised commutator surface. Instead of applying solder at an earlier stage the two cards could be joined electrically at this stage by welding at the terminal portions. Any spare conductive material at the terminal portions may then be removed.

Abstract: 712,076. Spray carburetters. CARTER CARBURETER CORPORATION. July 16, 1952, No. 17968/52. Class 7(3) A carburetter accelerating pump 33 is formed in the bottom of the float chamber 17 and comprises a spring-loaded diaphragm 32 closing the pump chamber 31 and operated conjointly by a stem 41 having a lost motion connection with a link 44 connected to the throttle valve operating lever 48 and by suction downstream of the throttle valve transmitted through a passage 52 to a space 51 formed below the diaphragm 32 by a cup 33, the stem 41 and link 44, which slide in guides 40, 43 in the float chamber 17, being located wholly within the confines of the float chamber except for the end of the link 44 connected to the throttle valve. The stem 41 passes through an aperture in a limb 45 of the link 44, spaced abutments 46, 54, providing a lost motion connection between the stem 41 and the limb 45. A metering needle 22 for the main fuel nozzle is carried by a bracket 42 fixed to the stem 41, and the accelerating pump has inlet and outlet passages 34, 36. On opening the throttle valve from the idling position, Fig. 1, the stem 41 is actuated positively to force fuel through passage 36 to the accelerating nozzle 38, Fig. 2, by engagement of the limb 45 with the abutment 46, but at each throttle setting the pump diaphragm 32 is movable by the intake pipe suction within the limits of the lost-motion connection between the stem 41 and the member 45. In a modification, Fig. 4, the diaphragm 70 closes a suction chamber 84 formed in the float chamber wall and connected to the intake pipe, and the pump pressure space is formed in a cup member 71 formed integral with a guide 78 for the diaphragm-operating stem 79 urged upwards by a spring 82 seated on an abutment 81. The stem 79 is resiliently connected to a link 89 actuated by the throttle valve and carrying an arm 91, through an aperture in which the stem 79 passes. A fuel metering needle 65 for the main fuel nozzle is connected to the stem 79 through a slidable arm 93 loaded by a spring 96. On opening of the throttle valve the arm 91 contacts the arm 93 to raise the needle 65 and actuates the diaphragm 70 through the spring 96. At any throttle setting the diaphragm is movable by the suction in chamber 84 and on closing the throttle valve the arm 93, and hence needle 65, follows the movement of the arm 91 until it engages a step 92 on the stem 79, after which it follows the movement of the stem 79. The fuel flows to the pump inlet 73 through a filter screen 74 on the cup 71.

Abstract: 977,385. Bridge measurements. ELLIOTT BROS. (LONDON) Ltd. Aug. 23, 1961 [May 23, 1960], No. 18169/60. Heading G1U. A Wheatstone bridge, particularly for measuring temperature, is first balanced as the temperature reaches a predetermined level; it is then unbalanced at this level and a first warning lamp operated, the bridge being again balanced when the temperature reaches a second level a fixed amount higher than the first and a second warning lamp is then operated. The bridge arms comprise fixed resistors 4, 5, 6, a variable resistor 3, a resistance thermometer R T  and a relay coil A1, the coil M of a movable coil instrument 9 being connected across the measuring diagonal. On the temperature reaching the first level, pointer contact 10 of instrument 9 engages and is magnetically latched to a fixed contact 12 which energizes relays a relay B which locks over its contact B/2 primes a relay coil C at B/1, discharges capacitor 23 over B/3 through a coil 22 to provide a pulse to release contact 10, lights a warning lamp L 2  over B/4, and unbalances the bridge by disconnecting resistor 5 at B/5 from one arm. If the temperature now rises to the second level, the contacts 10 and 12 will again engage to operate relay C, which at contact C 1  will light a further warning lamp L 3 . A fault occuring in R T  will cause an unbalance in the current through the coils A1, A2 of a double wound normally balanced relay. The relay contact A/1 will then operate to energize a relay D which locks over its contacts D/1, energizes a further warning lamp L 1  over D/3 and at D/2, prevents operation of lamps L 2 , L 3 . Keys SB1, SB2, SC, SA are provided for pulsing the release coil 22 and resetting the system to normal. In a similar embodiment the moving coil M is protected by being short circuited under fault conditions, the resistance thermometer R T , is connected in circuit through leads which compensate for temperature variations, and the keys SB1 &c., are connected in the circuit at different points.
