Abstract: 611,384. Cartridge-loading machines. OLIN INDUSTRIES, Inc. April 30, 1946, No. 13000. Convention date, July 14, 1944. [Class 9 (i)] [Also in Group XXII] An ammunition-loading machine comprises a work positioning and locking mechanism, safety means to prevent operation with work support maladjusted, and a work travel stopping device. Work positioning mechanism.-A series of rollers 2, Fig. 2, is held between a fixed thrust block 4 and a resilient member 5 in side channels 7 of a work supporting slide, so that introduction of angular members 1 between any pair of rollers 2 urges the slide forward to feed the work through one roller diameter. The slide is looked during the tool operating period by the members 1 which abut the resilient members 5 against the stops 3. Gravity or a one-way brake bearing on the channels 7 maintains the lock as the members 1 are withdrawn and the displaced rollers 2 are movedinto place by the members 5 prior to the next indexing movement. Adjustment screws are provided for the roller series and a free bar 48, Fig. 5, of the slide support 13 enables the slide to be removed clear of the operating mechanism and tools for mounting and removing the work. Operation.-A ram 15 supports the tools and members 1 and is toggled by a connecting rod 19 from a power driven eccentric shaft 15 with clutch 18 and key 29. Safety means.-When the slide is withdrawn operation is prevented by a screw 51 raising a quadrant 41 which lifts a spring-urged latch bar 33 to keep the sprung control handle 27 in engagement with the clutch key 29. With the slide correctly positioned the control handle 27 is free for manual depression thereof to start the machine. During operation the handle 27 is maintained free of the key 29 by a latch 38 engaging a notch 37 in the bar 33. Stopping.-At the travel limit the channel end plate 49 engages a release rod 36, pivots the latch 38 and releases the handle 27 to rise and stop the machine. In a modification the members 1 are carried by the work slide and the roller series are reciprocated. In a further modification the width of the members 1 is chosen to index more than one roller.

Title: Improvements in or relating to multi-channel or multiplex high frequency signalling systems
IPC: H03B5/30
Filed: 1930-04-29
Abstract: 353,906. Multiplex wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, MATHIEU, G. A., 3, Mayfield Gardens, Shirehall Park, and PUCKLE, O. S., 10, Lawrie Park Crescent, Sydenham, all in London. April 29, 1930, No. 13200. [Class 40 (v).] A multiplex transmitting system comprises a master-frequency source, means for producing a plurality of dissimilar frequencies from said source, means for separately modulating one of them by each of the others, and means for modulating the resultant frequencies by signals. In one modification the master-frequency source TF comprises a valve-maintained tuning-fork 1, and the master frequency is fed to a multi-vibrator circuit MV, the output frequencies of which are amplified at A passed through a high-pass filter F, further amplified at A1, and then fed to coupling coils C . . C, in series or series-parallel. The coil C is coupled to a selector S which passes one of the frequencies to a second multi-vibrator MV2, one of the frequencies from which is selected by S8 and fed to coupling coils C<1>1 . . C<1>7. The coils C1 . . C7 are coupled to selectors S1 . . S7 which pass seven different frequencies to the pairs of modulating valves V1, V<1>1 .. V7, V<1>7 to which the coils C<1>1 .. C<1>7 are also coupled. Keying of these modulators may be effected by keys K1 . . K7, arranged to alter the grid bias on the modulating valves. Band-pass filters F1 . . F7 which pass only the upper (or lower) sidebands follow the modulators and feed amplifiers A<1>1 . . A<1>7 whose output is combined in a composite unit CU, the mixed frequencies passing to a submodulator SM, modulator M associated with the drive D, side-band suppressor CF, power amplifier PA and radiating aerial A. A similar reversed arrangement may be used at the receiver. The radio carrier frequency may also be obtained from the tuning fork, and an extra frequency may be drawn from the system to modulate one of the channels for tuning-in and lining-up, and if desired two or three channels may be used together for telephony transmission. In a slight modification, Fig. 1a (not shown), an intermediate valve is placed between the source TF and multi-vibrator MV, being fed through a potentiometer and condenser, both of which may be varied to vary the amount of control exercised by the tuning fork. In a further modification, Fig. 2 (not shown), all the frequencies are produced by a series of frequency doublers and triplers. Specification 305,703, [Class 40 (v), Wireless signalling &c.], is referred to.

Title: Improvements in a method of making grated high-fat cheese
IPC: A23C19/086
Filed: 1954-05-07
Abstract: In making grated high-fat cheese, which does not agglomerate under ordinary atmospheric conditions, dried, comminuted, high-fat cheese is mixed with dried, finely-divided, high-fat processed cheese and the mixture is tempered until its fats are stabilized, oiling-off being thus prevented.  The term "high-fat" signifies that the cheeses concerned contain more than 40 per cent by weight of milk fat. Tempering may be effected at a temperature above the oiling-off point of the high-fat cheese, e.g. between 80 DEG  and 200 DEG  F., in air, having a relative humidity not exceeding 40 per cent.  The duration of temperating may be inversely proportional to the tempering temperature and may range from 15 minutes to 54 hours.  The high-fat cheese may be finely divided, dried at a temperature below its oiling-off point until it contains 10 to 15 per cent by weight of moisture and then mixed with sufficient of the finely-divided processed cheese, containing 2 to 3 per cent of moisture to give the mixture a content of 40 to 70 per cent by weight of processed cheese. The tempered mixture may be screened and packed.
