Title: Improvements in or relating to a portable van unit
IPC: F25D19/00
Filed: 1949-08-22
Abstract: 667,215. Loading and unloading rail-car containers: lift trucks. HODGES RESEARCH & DEVELOPMENT CO. Aug. 22, 1949. [March 30, 1949] No. 21734/49. Classes 78 (iii) and 78 (iv). [Also in Group XXXII] A portable van unit and co-operating individual truck carrying means for use in a system in which the vans may be transported by railway flat cars or'the like, comprises a van situated on the rail car, holding means on the rail car against which the van may be engaged and powered lifting means having a tined fork element co-operating with the van for loading on to and off the rail car. The underside of each van 10 is formed with a recess 20 of cruciform shape adapted to engage a similarly shaped projection 21 on the platform of the rail car and the recess has a locking mechanism associated with it so that after the van is set in position on the projection 21 the lock can be actuated to secure the van on the rail car. The locking mechanism comprises pads 22 loosely pivoted to the longitudinal interior vertical faces of the recess 20 and is provided with wedges 24 adapted to press against the rear faces of the pads 22 when the bar 25 is moved axially by springs 40. Lugs 32 are secured to the bar 25 for engagement with the tines 30 of a fork lift truck, the tines being inserted in holes 31 in the base of each container so that initial linear movement of the tines within the holes 31 unlocks the bar 25 and leaves the van free to be raised from the rail car. Each tine 30 of the lift truck is fixed to a threaded hub member which cooperates with a vertical worm shaft 41 driven through gears 40 and clutches 43 from a power driven shaft 42 so that the tines can be raised or lowered either differentially or in unison. The frame 45 which supports the elevating mechanism is connected by a link 46A to a power driven lever 47 to enable the frame to be inclined fore or aft.

Title: Improvements relating to internal combustion engines
IPC: F02M21/00
Filed: 1920-07-20
Abstract: 170,910. Sheppard, W. H. July 20, 1920. Fluid-actuated valves.-For controlling the richness of the combustible charge in accordance with the engine speed, the suction produced in the air inlet to the carburettor is used to adjust a valve controlling this air inlet, and also a second valve controlling a secondary air inlet direct to the induction pipe of the engine, the one valve being opened while the other is closed. In the form shown, the air-pipe 1 leading to the carburettor is formed with inlets 2 controlled by a ring valve 3, and a second pipe 6 communicating with the pipe leading from the carburettor to the engine is formed with inlet 7 controlled by a valve 8, the valves 3, 8 having trunnions 9 connected bv a lever 10 fulcrumed at 11. An extension of the lever 10 is connected bv a link 14 to a lever 16 fulcrumed at 19 and connected by a rod 18 to a piston 21 operated in a cylinder 22, the ends of which communicate with pipes 23, 24 opening in opposite directions within the pipe 1. A spring 25 on the link 14 normally maintains the valve 3 open and the valve 8 closed as shown. When the engine speed increases above normal, the velocity of air in the pipe 1 causes a greater pressure in the pipe 24 than in the pipe 23, so that the piston 21 is moved downwards, thereby closing the valve 3 and opening the valve 8, through which air enters directly to the engine. The fulcrum 19 of the lever 16 is adjustable along the member 5 and engages an incline 30 on the lever 16 so as to provide hand adjustment of the valves 3, 8 for varying the speed or stopping the engine.

Abstract: 1275731 Sheet-delivery apparatus LINOTYPE & MACHINERY Ltd 25 July 1969 [8 May 1968] 21769/68 Heading B8R In apparatus for delivering printed sheets from a rotary folding drum 2 in an overlapping stream, a kicker 11 for displacing one of the sheets relatively to the remainder at intervals to separate the sheets into batches is operated by an abutment 6 on a driven endless chain 5. As shown, the chain 5 passes over a driving sprocket 3 on the shaft 1 of the drum 2 and over a driven sprocket 4 on the shaft 13 of delivery tapes. As shown, the abutment consists of an elongatedlirik pin with wheels 60 at its end, and at intervals it engages an arm 8 on a shaft 15. A post 7 on the shaft 15 is connected by a rod 12<SP>1</SP> to the kicker 11, and a sprung surrounding the shaft normally holds the parts with the post substantially vertical and the kicker just below the delivery table 9 which is slotted at 29 to accommodate the kicker. Engagement of the abutment 6 with the arm 8 causes the kicker 11 to be moved downwardly and rearwardly and the spring to be stressed. When the arm is released, the spring causes the kicker to overshoot slightly its normal position so that it protrudes above the table 9 and hits a sheet 14 off centre to displace it. The frequency with which the kicker is operated can be varied by using chains 5 of different lengths, a jockey pulley 61 to take up slack being employed if necessary. Alternatively a second abutment 6 may be mounted on the chain. The sprocket 3 may be driven at a rotary speed proportional to the rotary speed of the press by any suitable means. If the size of the sheet produced by the folder is altered, a different kicker is fitted to the rod 12 in the proper position to engage the differently-sized sheet.

Abstract: 1478229 Rare earth metal aluminates PHILIPS ELECTRONIC and ASSOCIATED INDUSTRIES Ltd 21 May 1975 [24 May 1974] 21802/75 Heading C1A [Also in Division C4S] A rare earth metal aluminate is made by mixing a flux with the constituent oxide of the aluminate compounds producing the constituent oxides, and heating the mixture, where the flux is at least one of RbF, CsF and KF, and the rare earth metal (Ln) is yttrium and any element of AN = 57-71. It is preferable to use 0À1-15% by weight of flux based on the total weight of constituent oxides or compounds producing said oxides on heating. A heat treatment of 0À5 to 4 hours at 1200-1400 C is preferred. The flux may be removed from the reaction product after cooling by washing with water. The rare earth metal aluminates may be defined by Ln 3 Al 5 O 12 , having a garnet crystal structure and part of the rare earth metal (Ln) may be replaced by another rare earth metal, such as as in Y 3-x Ce x Al 5 O 12  where 0À005 # x # 0À5, or they may be LnAlO 3  having the perovskite crystal structure. These materials are used as luminescent materials, for example in cathoderay tubes.

Abstract: 460,721. Television. WALTON, G. W. Aug. 7, 1935, No. 22303. [Class 40 (iii)] The average light intensity of the picture 1 modulates an alternating current of a frequency which does not produce a visible effect on the image. The frequency is AB/C, where A is the picture frequency, and B and C are whole numbers such that B is not a multiple of C, as described in Specification 379,552. For example the frequency is a multiple plus one-half of the picture frequency. The output from a light-sensitive cell 9, which is influenced by light from the whole picture, modulates an alternating current, which is generated by a generator 11 run in synchronism with the scanning-device 2. Alternatively, the light falling on the cell 9 is interrupted periodically by a rotating disc with a ring of apertures, each with a transparency which varies sinusoidally in the direction of rotation, Fig. 3 (not shown). At the receiver, Fig. 2, the mixed currents are fed to two parallel circuits, one of which is coupled to means 17, which reconstitute the picture, while the other has a filter 20 for selecting the alternating current, and a rectifier 21. Part of the rectified output across an impedance 23 varies the grid bias of a valve in an amplifier 16 for the picture signals.

Abstract: 1,139,207. Monitoring data on a magnetic tape or disc. INTERNATIONAL BUSINESS MACHINES CORP. 23 May, 1966 [2 July, 1965], No. 22822/66. Heading G5R. Signals from and to a computer 60 are recorded and/or sensed on a magnetic tape 10 which moves at a velocity V past write and read head gaps 61, 62 in a surface 31 separated from the tape by a spacing h which is controlled by varying the vacuum pressure in ports S1 to S6, by means of a variable pneumatic resistance 52. If there is an error in the signal read by head 42 it is sensed by an error check circuit 21 which causes computer 60 to respond in a particular programmed manner to control movement of the tape forward, backward or to stop it in order to write, read, backspace block, forward space block or rewind the tape. Circuit 21 also sets an error trigger 22 and a pneumatic control trigger 28 which reduces pneumatic resistance 52 and decreases spacing h. The error is corrected by continually rewriting and rereading that part of the tape on which the error occurs, with the tape 10 and surface 31 separated by the reduced spacing h.
