Title: Rotary flowmeters
IPC: G01F1/22
Filed: 1969-10-23
Abstract: 1350570 Rotary fluid-flowmeters B RHODES & SON Ltd 19 April 1971 [23 Oct 1969 28 April 1970] 52025/69 and 20347/70 Heading F1F Fluid-flowing upwardly in a passageway 4 of circular cross-section lifts and revolves a rotor 12 due to the presence of helical vanes 20 and a frusto-conical tail part 100. Fixed axiallystraight guide vanes (not shown) may be lodged in the passageway below the rotor. The angular velocity of the rotor may be detected by e.g. a light source 25 and detector 24. In a second embodiment, Fig. 2, the rotor 6 is ionic and has vanes 32, rotation of the rotor being discerned by a detector 224. Alternatively, the rotor has a cusp-shaped profile, Fig. 3 (not shown). A third embodiment, Fig. 4 (not shown), is generally similar to that according to Fig. 1 saving that the blades of the rotor are axially straight and the guide blades are helical. The rotor may have a tail part with helical grooves formed in its frustoconical surface such that the torque produced by the flow therethrough either assists or opposes that due to the flow between the blades of the rotor, Figs. 5 and 6 (not shown). To permit a larger range of flow-rates (without causing, an excessive rotor speed) the Fig. 1 embodiment may be modified inasmuch as the passageway is given two frusto-conical portions, one being disposed immediately above the other and having a greater apex angle, Fig. 7 (not shown). In a fourth embodiment, Fig.8, compensation for loss of torque due to drag at a conic nose portion 142 is provided by additional torque obtained from drag on a cylindrical part 152 as a result of rotational flow component induced by fixed helical blades 156.

IPC: F16B39/34
Filed: 1967-11-29
Abstract: 1,215,305. Moulding plastic substances. STANDARD PRESSED STEEL CO. 29 Nov., 1967, No. 54271/67. Heading B5A. [Also in Divisions B2, F2 and H5] Apparatus for applying a plastics element to a localized area of a workpiece, e.g. a bolt, comprises a holder to grip the workpiece so that the area is exposed to induction heating means for heating the exposed surface area, a punch member and means for moving it from an inoperative position to an operative position to an inoperative position where it engages the workpiece, an indexing mechanism for feeding plastics ribbon between the punch and workpiece, air jet means for cooling the workpiece and punch in its operative position and induction heating means for heating the punch in its inoperative position. As shown, workpiece holders H 1 , H 2  are mounted on a table T which is moved by a cylinder C and are independently moved by cylinders C 1 , C 2  in a direction perpendicular to this so that the workpiece W can be positioned under heating means HC, or HC 2  respectively. The workpiece holder is first moved under the heating means and then the table is moved to position the heated workpiece under the punch P. The jaws 23, 24 of the workpiece holder are arranged so that the jaw 24 is resiliently urged towards the jaw 23 to allow positioning of the bolt in the jaws as spring loaded stop 46 also being provided to axially fix the position of the bolt to be coated. When the workpiece holder moves under the heating means a cam follower 38 causes the jaws to be locked in position and hold the bolt firmly. After heating the table is moved by cylinder C to a position under the punch P and the punch is operated by a vertical pneumatic cylinder to shear a ribbon R of plastics material and force it against the bolt W. The punch P is heated in its raised position by inductive coils containing water and is formed of a suitable alloy such that its temperature can be changed rapidly as when it has reached its operative position the workpiece and punch are subjected to air jets from nozzles (160, 161) to cool the coating material. As the workpiece holder is retracted when the punch is raised, an ejector arm 63 normally held down in a horizontal position is tripped by an arm 65 acting on a fixed stop and move upwardly and eject the coated bolt. As shown in Fig. 5, a vertically reciprocable needle 95 is moved down to penetrate the plastics ribbon R and a cylinder C4 moves the needle and hence the ribbon towards the workholder. When the feed indexing movement ceases a clamping pin 110 is moved by pneumatic cylinder C6 to hold the ribbon and punch P descends to shear the ribbon between the surface 105a and the punch P. Two work-holders and heating stations and a single punch are provided and movement is arranged so that as one is heating the other is cooling under the punch and as one is loaded the other is being unloaded. In a modification (Fig. 20) the work-holder 203 is arranged on a circular rotatable table and passes below a heating element 204 and a punch 206.

Title: Apparatus for deriving justifying signals
IPC: B41B27/36
Filed: 1971-11-29
Abstract: 1360074 Control of printing machines INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1971 [28 Dec 1970] 55284/71 Heading G4H  In apparatus for deriving, from a train of  coded text signals, signals representing the  arrangement thereof into justified lines of a preselected line measure for a printer 5, a recycling scan process renders the capacity of a buffer store 2 effectively infinite by effecting alternate input and output simultaneously with  calculations by a computer 3.  When there is adequate storage capacity in the store 2 for computing a justification solution for an output line, enough signals are fed into the buffer to form a justified line after which the computer introduces an end of input memory (EOM) signal, halts the input from reader 1, resets a memory address counter to the address of the first character signal of the current input line, and finally effects output of the data to the printer. At the end of a printed line a carrier return signal 103 resets the printer and sets a scan latch 16. Any data remaining in the store 2 goes on the next line and is diverted by gates 11, 8 (respectively inhibited and enabled by the latch 16) to the input again. These signals are then treated by the computer 3 as new input (although they are already in the store) and a counter 12 increments again until the EOM signal is detected by a decoder 7; this resets latch 16 so that the output signals can be fed to the printer, and the data input is resumed, the recycling process allowing the computer to include the stored data in its calculations for a new justified line. When more signals are required by the computer to calculate a justified line than the store 2 (capacity n) can hold, the computer effects data input until counter 12 reads (n-1), whereupon a buffer latch 14 is set and the EOM signal is generated to form the nth input to the store via gate 10. The computer then resets the memory address counter but continues the output to the printer until a space signal (or, alternatively, a signal in a preselected address) is detected by a decoder 6; this enables a gate 15 to set scan latch 16 so that the above recycling process takes place until the EOM signal is detected. (During this process the computer has assigned a minimum interword spacing to the printed output, and kept a record thereof in order to compute a justification solution for the whole line.) Then the latches 14, 16 are reset, data input is resumed, and the output is printed, the computer thus operating as if the whole line had been fed in continuously without reaching the buffer capacity (the recycling process being repeated if the input required to justify the line is still too large). If exactly (n-1) signals suffice for the computation then a signal 21 resets latch 14 and prevents the above recycling process. The input signals may be derived from paper or magnetic tape, or from punched or magnetic cards, and may be augmented by signals from a keyboard.

Abstract: 1,139,106. Data processors. INTERNATIONAL BUSINESS MACHINES CORP. 14 Dec., 1966 [22 Dec., 1965], No. 55901/66. Heading G4A. In a data processing system, accessing of one of a plurality of storage locations by one of a plurality of requesting units stores a predetermined bit configuration in the location to indicate it is being accessed, each unit having means for testing for this configuration. Separate processors or programmes in a computer system may access respective and common core (or transistor) memories and set a portion of the accessed word location to a predetermined bit configuration, e.g. all ones, or all zeros, to indicate that the location is being used. This may be done by destructive read-out not followed by regeneration, by blocking inhibit drivers, or by inhibiting AND gates or pulsing OR gates in the regeneration path. The setting to a predetermined bit configuration may be done in response to detection of a particular address(es) or instruction(s), or while a certain latch is on. This latch is set by a manual switch or on detection of a particular instruction and is reset by the same switch or on detection of another particular instruction. Setting to a predetermined bit configuration may alternatively be done in response to detection of a particular address(es) only if the latch is on. If one processor or programme is using a given word location it may set a particular bit configuration into part of it and if any other processor or programme then attempts to use it, this further use is prevented but part of the predetermined bit configuration stored is changed to indicate to the first processor or programme that another is waiting so that it may branch, for example, to give the second processor or programme access.
