Title: Method for producing printed publications
IPC: B65H39/055
Filed: 1967-01-26
Abstract: 1,124,415. Collating sheets. INTERNATIONAL BUSINESS MACHINES CORP. 26 Jan., 1967 [8 Feb., 1966], No. 4002/67. Heading B6H. A method of producing a printed publication having printed sheets comprises printing a repeated portion on both sides of a web W, Figs. 1 and 2, each repeat having a plurality of different page sheets arranged along the length of the web and a plurality across the web, perforating the sheets along the edges of the sheets if desired by a punch drum 26, cutting the web longitudinally into strips along the sheet edges by rotary cutters 32, cutting the web laterally into press sheets and further into page sheets by rotary knives 36, 38, feeding the sheets by belts 40 into overlapping relationship on slower-moving conveyor belts 44 below tension rollers 56, and thence into stacks side by side on a platform 58, each stack comprising sheets from one lateral position on the web arranged alternately in order of the page sheets. The stacks are then placed in hoppers 68 at collator feed stations 60, Fig. 3, and at each station sheets are fed in succession from the bottom of the stack by a rotary suction device 70 on to support surfaces 64 of a moving belt 62 having collating fingers 88 so that new stacks are formed on the surfaces 64, each comprising in turn a plurality of sheets from each station according to the number of page sheets displaced longitudinally along the web in each press sheet. In one'form, if there are two such page sheets, alternate fingers 88 are removed. Alternately, the belt is fed intermittently, being stationary while one sheet 'from a station is fed and moving when the second is fed. Alternatively, the feed from the stations is made twice as fast or the belt travels at half speed. If the publication contains an odd number of sheets, the last station 60 has a stack of one kind of sheet only, and the suction device 70 is operative only each second cycle. 'Some of the belts 44 adjacent the inner edges of the outer sheets may be driven faster by means of larger drive rollers 52 to avoid lateral interleaving. An electrical sensing device at each station 60 detects absence of a sheet, and a further sensing device 92, Fig. 3, detects that the correct sheet is being fed from the stack by sensing cheek marks or perforations on or in some of the sheets. In another form, for collating two halves (or several sections) of a book, each repeat comprises non-sequential page sheets. spaced longitudinally, bearing a similar relationship to the two halves, e.g. pages 1-2 and 33-34 where the halves consist of 32 sheets each, and collating one sheet from each stack to form a new stack; The new stacks are the fed by a conveyor 98 and belts 100, Fig. 7, to a turning delivery bed 104 and thence on to a conveyor 106 of a a stitching machine 108.

Title: Production of improved virus vaccine for canine distemper
IPC: A61K39/175
Filed: 1960-02-05
Abstract: An improved virus vaccine for canine distemper is obtained by passing canine distemper virus through live chick embryos for a sufficient number of passages to produce avirulence, inoculating the avirulent virus into a culture of chick embryo tissue and incubating and harvesting the resulting vaccine.  Tissues from chick embryos of various ages may be used but tissues from nine day old embryos are preferred.  Trypsinized chick embryo tissues are prepared in a conventional manner and are suspended in a growth medium fluid consisting of Earle's basal medium containing 0.5% lactalbumin hydrolysate and from 15 to 20% normal calf serum. Insulation was made with the 48th passage of modified canine distemper virus through live chick embryos.  Incubation was for 7 days at 37 DEG  C.  The avirulent virus is passed serially through a plurality of chick embryo tissue cultures and then the harvested vaccine is freeze-dried.  The resultant canine distemper virus is free from contamination with the tissue of the chick embryos.

Title: Improvements in or relating to apparatus for use in radio guide-beam navigation systems
IPC: G01S19/04
Filed: 1944-03-04
Abstract: 599,254. Radio navigation. SPERRY GYROSCOPE CO., Inc. March 4, 1944, No. 4264. Convention date, March 4, 1943. [Class 40 (v)] In an approach or glide-path receiver operating an indicator or navigational controlling device, the effective sensitivity of the indicator or controlling device is automatically reduced as the craft approaches the source radiation under control of distance-determining means so that a course displacement signal or control is obtained which is proportional to the lateral departure of the craft from course, as distinct from the angular departure,.over a wide range of distance. This may be achieved by providing the receiver with forward-acting A.G.C. or by the provision of a distance-measuring device, or an altimeter, which controls means decreasing the input of the indicator or controlling device in proportion to the distance of the craft from the source of radiation or the altitude of the craft respectively. Fig. 4 shows a glide-path receiver comprising two I.F. stages 47, 48, a detector R with an A.G.C. generator 22, two A.F. stages 49, 50 and an indicator or navigation controlling device 17. A.G.C. is fed to both the I.F. stages 47, 48 and also to both of the A.F. stages. In Fig. 8, a distance or height-determining control unit 29 controls a potentiometer 33, shunted across the input terminals 34, 36 of a visual indicator 18 and arranged to reduce the sensitivity of the indicator as the aircraft loses height or approaches the beacon. The unit 29 may also control a duplicate potentiometer 39 for similarly reducing the sensitivity of a flight controlling device (not shown). The control unit 29 may be a barometric altimeter or any distancemeasuring means, e.g. one controlled by time or by radar means. Specification 550,660 is referred to.

Filed: 1964-01-31
Abstract: 1,021,481. Variable-speed friction gear. P. C. PRAGER. Jan. 31, 1964 [Feb. 4, 1963], No. 4264/64. Heading F2D. A continuously-variable-ratio friction gear comprises a driving shaft 9 fast upon which is a disc 10 having a hollow cone-shaped friction face engaged by the edge 24 of an inclined roller 23, in turn engaging an edge 25 with a similar coneshaped friction face formed in a disc 18 fast upon a driven shaft 17, a bearing ring 29 journalling the roller pivoting about a pin 28 to permit movement of the roller transversely to the axes of the driving and driven shafts, while rotation of a ratio-shift knob 38 screws the bearing ring in the plane of the two shafts to change speed. As shown, the driven shaft 17 is journalled within a ring 13 in screw-threaded engagement with the gear housing 2 and biased by a spring 20, while the engaging edges 24, 25 of the roller 23 are of spherical cross-section. Alternatively, the ring 13 may be fast in the gear housing 2. To oppose tilting of the inclined roller 23 under torque loading, the centres of the curvature M, Fig. 2 (not shown), of the spherical engaging surfaces 24, 25 on the roller are separated from each other, and do not lie upon the axis of rotation of the roller. The engaging surfaces 24, 25 of the inclined roller 23 may alternatively be of hyperbolic or other configuration., Pivoting of the bearing ring 29 about its pin 28 permits torque-dependant wedging of the roller 23 between the opposed cone-shaped friction faces on the driving and driven discs 10, 18.

Filed: 1928-02-13
Abstract: 311,460. Automatic Telephone Manufacturing Co., Ltd., Paulett, W. H., and Gillings, C. Feb. 13, 1928. Automatic exchange systems; metering.-A delayed metering arrangement comprises two relays energizing in succession with a definite time interval over two common time-pulse conductors, the circuits being such that on reply of the called party the first relay energizes and locks up over the same winding while the second relay opens both energizing and locking circuits of the first relay simultaneously with the completion of a metering circuit over operated contacts of only one of the relays. Relay MP, Fig. 1, energizes over armature 10 of an answering supervisory relay and an intermittently earthed conductor 11, locks up over 13, 14 and an armature 15 of a guarding relay, and prepares at 18 a circuit for a metering lead 17 over a second intermittently earthed conductor 16. If armature 10 has not in the meantime fallen back, the next earth pulse over conductor 16 operates the meter and energizes relay MZ which locks up over 19, 15 and at 12, 14 breaks respectively the energizing and locking circuits of MP which, however, is held over a second winding during the pulse over 16. In a modification, MP has a single winding and MZ is a two-step relay which, on occurrence of the pulse over the second conductor, first prepares a locking circuit for itself which is ineffective during the pulse. After the pulse has passed, MZ operates fully and releases MP. In the further modification shown in Fig. 3, MP energizes over armature 200 of supervisory relay and pulse conductor 211, locks up over 215 as before described, and prepares a circuit at 218 for MZ. The pulse over conductor 216 energizes MZ which completes a metering circuit from lead 217 over operated contacts of MZ to ground at 215, and releases MP. The metering circuit is maintained until MZ is released by removal of the guard at 215.
