Title: Improvements in and relating to machines for joining together lengths of cloth
IPC: D05B85/06
Filed: 1950-11-25
Abstract: 695,820. Sewing-machines. HARRAP, Ltd., N. W., and JOHNSON, J. S. Nov. 23, 1951 [Nov. 25, 1950], No. 28878/50. Class 112. A butt seam is produced by stitching together two superposed work-pieces in an overedge sewing-machine, the stitches being formed round a projection on the work-plate or presser-foot or both so that they are loose enough to allow the work-pieces to lie flat when opened out. Loop-stitching; loose stitches, producing.- The needle 17, Fig. 4, is carried by an arm 16 freely mounted on a shaft 15 perpendicular to the line of feed and oscillated by an eccentric 18, Fig. 1, on the main shaft 13. The under looper 43 is carried by a shaft 44 and is oscillated by another eccentric on the shaft 13, while the overedge looper 42 is mounted on a shaft 49 and oscillated by an eccentric 51 on a shaft 34 geared to the main shaft 13 to run at the same speed; the shafts 44, 49 are slightly inclined to the line of feed on opposite sides thereof so that the loopers pass on opposite sides of the needles. The stitches are tightened round a projection 60, Fig. 4, on the presser-foot 53 so that on removal of the work they are slack enough to allow the seam to be opened out flat; as an alternative to the projection 60, a projection on the work-plate may serve a similar function. Feed by dogs.-The feed-dog 23, Fig. 1, is fixed to a plate 22 which is slidable longitudinally in a carriage 30 pivotally mounted at the rear end on the shaft 15 by arms 31 and supported at the front end by a pitman from an eccentric 33 on the shaft 34, whence it receives a rising and falling movement; the feed movement of the dog is derived from the shaft 13 by means of an eccentric 21 with adjustable connection to an arm 27 of a member 26 rocking on the shaft 15 and connected by a link 24 to the plate 22. Trimming.-The edges of the work-pieces are trimmed, before being sewn, by a vertical blade 38, carried by an arm 40 on the rising and falling feed carriage 30, co-operating with a stationary blade 39 carried by a. spring-loaded spindle 41 which presses the blades together; the blades are slightly inclined to one another both in plan and in elevation, giving a shearing and hollow-ground effect. The cutting takes place as the feed-dog descends after feeding the work. Presser-feet; presser-bars.-The presser-foot 53, Fig. 4, has an upturned front edge with a lateral extension 54, and is mounted on an upright member 55 pivoted to the presser-arm 57, which is pivotally mounted on a bracket 58 and is pressed downwards by a spring 59.

Title: System for checking the performance of a dynamoelectric machine overheating detector
IPC: G01K11/00
Filed: 1972-06-21
Abstract: 1367375 Electro-physical testing GENERAL ELECTRIC CO 21 June 1972 [31 Aug 1971] 28926/72 Heading G1N [Also in Division H2] An overheating detector for a gas cooled dynamo-electric machine is provided with a system for checking its performance. A generator 1 is cooled by hydrogen flowing from the machine via conduit 7, through test device 12, ion chamber detector 16 and back to the machine, via conduit 8. If any sub-micron particles are evaporated from parts of the generator due to overheating they are detected at 16. In accordance with the invention the test device 12 comprising a filament 33 coated with a polymeric material is applied with a current from the supply for a short period so that some of the polymeric material is evaporated and passes via by-pass conduit 15 to the detector to produce a signal which simulates overheating. The gas is then directed through a filter 14 to test whether a signal is again produced. The ion chamber detector 16 may be of the type described in Specification 1186525, Div. H1.

Abstract: <PICT:0428858/III/1> Emulsifying - apparatus, especially suitable for the production of artificial cream from butter and milk, and constructed to permit the removal of salt from salt butter, when such is used, prior to the addition of the milk, comprises a receptacle 1 for the ingredients, a tubular member or cylinder 6 at the base thereof, a plunger 7 reciprocated in the cylinder by means such as a link 11 connected to a lever 8 pivoted to lugs on the receptacle by a pin or thumb-screw, a spring-pressed valve 23 within the cylinder providing a restricted outlet for the materials, the valve being readily releasable, and one or more lateral apertures 25 in the cylinder for ingress of the ingredients on raising the plunger. The cylinder 6 preferably extends into the receptable being held by a nut 15, and the valve preferably comprises a plug having a pin 22 extending into a restricted passage 18 in the cylinder, the valve-spring 24 being held by a screw-threaded nozzle 20.  A conical annulus 12 may be suspended within the receptacle by links 13 and serves as a preliminary mixing and agitating device.  The apparatus is supported in a bracket arm clampable to a table and having a cup-shaped upper end through which the cylinder 6 is inserted, the cylinder being held by a nut 16.  In use hot water may be poured upon salt butter placed in the receptacle to extract the salt therefrom; slackening of the nozzle 20 to loosen the valve, or entire removal of the valve and nozzle, then permits outflow of the water on raising the plunger 7.  Milk is then added, the valve replaced or tightened and artificial cream produced by pumping the mixture through the apparatus.

Title: Improvements in high frequency electric oscillators
IPC: H03B5/34
Filed: 1936-10-26
Abstract: 462,447. Piezo-electric crystal mountings. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 26, 1936, No. 29057. Convention date, Oct. 25, 1935. [Class 40 (v)] [Also in Group XXXVI] An oscillator for checking the carrier frequencies of radio transmitters or for like purposes is tuned by means of a piezoelectric crystal mounted with a tuned circuit in an interchangeable plug 18 which can be inserted into the oscillator. The anode circuit 19, 22 is tuned slightly above the desired frequency, and the frequency is precisely regulated during manufacture by adjusting the relative positions of the crystal cell 20 and coil 19, so as to vary the extent to which the metal electrodes of the cell lie in the magnetic circuit of the coil. The coil 19, Fig. 2, is preferably annular and the crystal cell 20 is soldered to leads 23 which pass through hollow plugs 13 so that the position of the crystal cell can be adjusted by manipulating the leads, which are soldered to the lower ends of the hollow plugs when the frequency is correct. The plane of the cell may be at right angles to that of the coil for the higher frequencies, but for the lower frequencies the cell may be parallel to the coil so that its metallic parts lie to a greater extent in the magnetic field of the latter. A condenser 22 may be shunted on the coil for the lower frequencies but omitted for the higher frequencies. The parts are fixed in position by filling the container 18 with a sealing compound, or for the higher frequencies with rock wool (in order that the filling may not affect the frequency). The crystal cell 20 comprises metallic electrodes 21, Fig. 3, an insulating annulus 25, a crystal 26 with floating electrode 27, and a crow-foot spring 28 for fixing the crystal and making electrical connection.
