Abstract: 1,240,439. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 18 May, 1970 [2 June, 1969], No. 23901/70. Heading B6F. Matrix printers.-A matrix printer comprises a stack of selector plates such as 60-63, Fig. 13, each associated with one of an array of printing elements 0-9, Y, Z, Fig. 2, in a print head 24 and movable in selected combinations by keys 70 to actuate a corresponding selected combination of printing elements for effecting printing. The selector plates have registering apertures for passage of the keys therethrough, each key on depression urging a cam member 112 to the right by means of a pair of rollers mounted on the key stem, the cam selectively urging or not urging each selector plate forward according to the size of the aperture in which it is located. The printing elements comprise blades arranged in a quartered square or parallelogram. Power operation.-The selector plates 60-63 may be operable by power means comprising a continuously rotating power roll 214 having a flexible band 216 wrapped around it, the band being engageable with the power roll by energization of an electromagnet 238, whereby a roller 234<SP>1</SP> is urged against the power roll 214. The band is connected to a lever 218 which is coupled to an actuating lever 230<SP>1</SP> for one of the plates 60-63. An actuating mechanism is provided for each plate 60-63. In a modified power-operating arrangement (Fig. 14) a latch assembly (25111, 26011) is provided to disengage the roller (234<SP>11</SP>) from the power roll (214<SP>11</SP>) after a predetermined length of stroke. Keys operating contacts.-The levers 230<SP>1</SP> may operate switch contacts (232, 234, Fig. 5) to give a coded electrical output for transmission to a computer. Letter spacing.-A selector plate 58, Fig. 13, is actuated on depression of any key 70 or a space key 100 and operates a letter spacing escapement mechanism (Figs. 9, 10) urging the print head 24 along the line. The escapement mechanism comprises three selectively operative ratchet wheels (173, 175, 180, Fig. 10) corresponding to different letter space increments, a pawl (163, 165, 170) corresponding to one of the ratchet wheels being selected by a lever 148, Fig. 13, and being movable to release the ratchet wheel by operation of the selector plate 58. Line spacing; card holders; bar platens.-A card to be printed is supported against a bar platen 135, Fig. 13, and may be manually moved between steps 138 on a card support. Alternatively, a ratchet-and-pawl mechanism operating on actuation of a carriage return lever 134 may move the card from step to step. The line feed increments may be varied in correspondence with variation of letter spacing by the lever 148 rotating a cam (188, Figs. 3, 10). Inking - arrangements.-Printing may be effected through an ink ribbon (not shown), or by capillary feed of ink from a reservoir 28, Fig. 2, to the tips of the blades 0-9, Y, Z, which are suitably formed of a plurality of leaves of differing lengths.

Title: Improvements in machines for disintegrating or emulsifying materials
IPC: B01F7/00
Filed: 1922-09-04
Abstract: 209,135. Povey, H. Sept. 4, 1922. Emulsions, making. - In a high - speed centrifugal machine for disintegrating, emulsifying, or mixing materials, the material during treatment is projected centrifugally by one or more rotatable members and discharged therefrom intermittently. The invention is described and shown as applied to a machine for disintegrating a solid' mixed with a liquid. The members 3, 4 carrying intermeshing rings of blades 31, 32 and intermeshing annular projections 35, 36 are mounted on shafts driven in opposite directions by means of pulleys 39, 14. The shaft 9 of the member 4 rotates in bushes 10, 11 on a bearing 6 and an annular supporting member 12 respectively. The inner end of the bush 11 is fitted with a packing- gland 16, and rubber packing-rings 20 are inserted in registering grooves 18, 19 on the member 12 and casing 2 respectively. The inner end of the member 12 is fitted with a packing-gland 21 to form a tight joint between the hub 23 of the member 4 and the member 12. A duct 24 in the member 12 is made to register with a port 25 or with a port 27 according as the material to be treated is supplied through a pipe 26 on the top or a pipe 28 on the bottom of the casing. Axial ducts 30 in the hub 23 lead the material to the space between the members 3, 4. The member 3 is mounted on its shaft in a similar manner to the member 4. The material after treatment by the blades 31, 32 passes through a narrow .annular duct 33 into an intermediate annular chamber 34 of circular cross-section and then through holes 37 in the axial projections 35, 36 when these holes register with one another. An annular plate 38 secured to the member 3 pravents leakage, through the clearance-space between the projections 35, 36. Nuts 40, 41 are provided on the driving-shaft of the member 3 for adjusting the clearance between the members 3, 4. The treated material is collected in the chamber 43 and discharged through a pipe 44. The holes 37 may progressively decrease in size from the innermost to the outermost projections, and the sides of the discs may be corrugated, serrated, &c. In a modification, a single rotating member with blades intermeshing with blades on the casing is used. The intermediate chamber 34 mav be dispensed with so that the material passes directly from the duct 33 into the holes 37.

Abstract: 1,151,276. Overhead travelling cranes. WELLMAN MACHINES Ltd. 19 March, 1968 [24 May, 1967], No. 24072/67. Heading B8B. An overhead travelling crane comprises a bridge with a carriage 11 at each end. Each carriage 11 has a bogie 12 at each end providing a bogie 12 at each corner of the bridge. Each bogie 12 comprises a beam 22 pivoted at 23 to the associated carriage 11. Hydraulic jacks 39, 40 are mounted one at each end of the beam 22. Should one of set 18 to 21 of wheels be damaged or otherwise require attention jack 39 is extended so as to raise carriage 11 and thus the pivot 23. This results in set 18 to 21 of wheels being lifted from track 13, as shown, so that the crane can be moved to a maintenance station without using the elevated wheels 18 to 21.

Abstract: 1345779 Pulse regenerators, digital transmission FUERXER 19 April 1971 [6 March 1970] 24108/71 Headings H3T and H4P In a pulse regenerator system for multilevel signals the output and input of a regenerator circuit 3 are compared at 7 and the result passed through a low-pass filter 8 to an adder 2 preceding the regenerator, to correct the D.C. and low frequency components. A delay circuit 5 equalizes the delay to the two inputs of the comparator and the regenerator circuit 3 may be clocked. Fig. 4 shows the regenerator system 2-8 and also a clock synchronizer comprising a phase detector 15 comparing the input and output of the regenerator, an amplifier 16 and a low-pass filter 17. The level of the input signal or of the regenerator threshold is controlled by applying to a phase comparator 12, such as a ring modulator, the output of the regenerator and the output of a circuit 9 detecting the difference between the higher frequencies of the input and output of the regenerator, each path including a respective high-pass filter 10, 11. The resulting output is used to control the regenerator circuit threshold or the gain of an amplifier preceding the regenerator system.
