Abstract: 1,232,233. Stabilization of convertiplane proprotors. TEXTRON Inc. 8 May, 1968 [10 May, 1967; 28 Aug., 1967], No. 21707/68. Heading B7W. In a convertible aircraft provided with a teetering rotor which is tiltable through 90 degrees to act as a lift rotor in one mode (Fig. 5) and a propeller in another mode, a cyclic pitch linkage is provided whereby an increase in pitch angle (positive pitch-flap coupling or negative delta-3) is obtained if upward or forward flapping of the blade occurs when the linkage is fixed in position, i.e. in the aeroplane mode. This leads to the out-of-plane natural flapping frequency of the blade decreasing with increasing forward flight speed so as to be always less than the blade in-plane flapping frequency thereby preventing rotor instability occurring through coupling of in-plane and out-of-plane flapping frequencies. The linkage comprises a swashplate 102 which is connected through control rods 106, 105 to the pitch horns of two rotor blades 11, 11a semi-rigidly mounted on a hub 100 pivotally mounted on a rotor shaft 101, the swashplate being controlled by a control linkage 104 comprising a control stick 113, control link 114, lever 115, link 116 and swashplate attachment bracket 117 to provide controlled collective pitch variation. The pitch horn-control rod attachment points 108, 109 are located on an axis 107 selected to produce a delta-three angle that is negative and is greater than zero but less than 45 degrees. With such a delta-three angle, upward or forward flapping of a blade produces a downwardly or rearwardly acting force on the appropriate pitch horn-control rod attachment point and since the pitch horn is held in position by the swashplate which is also held, the appropriate blade rotates to produce an increase in pitch. A formula giving the permitted maximum amount of positive pitch-flap coupling is supplied. This formula incorporates a term, i.e. hub rock representing the elastic out-ofplane blade deflection occurring as a result of elastic in-plane blade deflection.

Abstract: 1,233,305. Roller burnishing. MADISON INDUSTRIES Inc. 21 July, 1969 [19 Nov., 1968], No. 36503/69. Heading B3M. A roller burnishing tool includes a mandrel 10 having interengageable parts 11 and 12 which can readily be separated. A cage 30 carrying tapered skewed rollers 32 embraces the part 12, and is provided, in one embodiment, with apertures 33, 34 for allowing a pin 16 holding the parts together to be removed. The parts may alternatively be connected by a key 28 and screw 29, Fig. 8. The cage is coupled to a sleeve 35 which bears against a thrust bearing 56. To adjust the radial position of the rollers, the cage is moved axially relative to the mandrel. This is effected by moving of the bearing axially. The bearing is urged by a spring 60 towards a nut 52 keyed to an outer housing 42. The nut is internally threaded and can be adjusted by rotation of the housing. Before the housing can be rotated, however, a lock nut 55 is released and toothed ring 45, which is keyed to the mandrel, is moved out of engagement with the nut 52. The spring 60 allows the housing to be moved to disengage the ring 45 and nut 52, and also serves to urge the cage towards the bearing 56 and the adjusting nut 52.

Abstract: 1,233,792. Data processing; data stores. INTERNATIONAL BUSINESS MACHINES CORP. 15 Aug., 1968 [27 Sept., 1967], No. 39073/68. Headings G4A and G4C. A data processing system comprises a dynamic address translation device, co-operating with a stored table of relocated addresses corresponding to logical addresses, to gate for addressing a store the relocated address corresponding to an interrogating logical address in response to an " equal " comparison of the latter with a stored logical address. A multi-processor or multi-programme timesharing system can transfer pages of information between a disc backing store and a main core (or transistor) store as necessary. An " active " store (transistor type) includes respective predetermined locations holding the main store addresses of the latest instruction (viz. an instruction counter), first operand and second operand. When the main store is to be addressed using any of these addresses the address is supplied on a bus to a dynamic storage relocate unit which passes the low order portion to a main store address register and compares the high order portion to the contents of one of three " high " registers (according as the address relates to an instruction, first operand or second operand respectively, as indicated by which location of the active store was read out to get the address). If equal, the contents of the appropriate one of three " low " registers is gated to the main store address register to form the rest of the address. If unequal, machine status is saved in the active store, the high order four bits of the address are added to the middle of the highest order (8-bit) byte of the base address of a segment table in main store to address one entry of this table. This entry gives the base address of a page table in main store. Part of the appropriate " high " register is added to this base address near its low order end to address one entry of the page table, the contents of which are passed to the appropriate " low " register. The machine status is reloaded and the programme resumes. The appropriate " high " register has since been loaded from the bus mentioned so the comparison now gives equality and the appropriate " low " register (now contaming the relocated address) is gated to the main store address register. The active store also holds the last accessed segment table entry for each of the cases: instruction, first operand, second operand, in respective predetermined addresses.

Abstract: 1,234,015. Transport flask. COMMISSARIAT A L'ENERGIE ATOMIQUE. 10 Feb., 1970. [10 Feb., 1969], No. 6324/70. Heading B4Q. The loading end of a cylindrical flask 10 (having a horizontal axis as viewed in Fig. 2) includes a cylindrical housing 16 having a vertical axis for receiving a barrel 49 rotatable on a central ball bearing 50. A duct 14 extending along the axis of the flask 10 receives a container 34 for radio-active articles, the space 20 being filled with lead. The barrel 49 has a central passage 53, whereby when the barrel is rotated through 90 degrees from the position shown after a plug 24 is removed, the container 34 may be transferred between the duct 14 and the flask exterior. When the plug 24 is in position it engages a recess 54 in the barrel to prevent its rotation. The barrel 49 is retained in the housing 16 by a key 58 having flanges 70, 70<SP>1</SP> co-operating with slideways 72, 72<SP>1</SP> formed in the flask. The flat inner surface 60 of the key has a cylindrical extension 62 of a diameter equal to that of the barrel 49 and the depth of the flanges 70, 70<SP>1</SP>, as viewed in Fig. 2, is less than that of the slideways 72, 72<SP>1</SP> by an amount at least equal to the height of the cylindrical extension. Thus, the key 58 may be slid horizontally into position whereupon the extension 62 drops into the housing 16. Blocks 74 (only one shown) are then slid into the clearances and secured to the flask, whereby the key is locked in position. The key 58 includes a socket 64 receiving a shaft 67 engaging a square hole 66 in the barrel so that the latter may be rotated by a handle 52 coupled to the shaft. The construction avoids the use of screws or pins to retain the key 58 which are likely to break in the event of the flask being dropped.

Abstract: 1,234,406. Boxing articles. GOLDEN WONDER Ltd. 6 Nov., 1968 [2 Oct., 1967], No. 44647/67. Heading B8C. Articles, particularly fragile and/or flexible packages such as packets of crisps, are boxed by feeding them to a packing station where they are supported over an open box by clamps engaging opposed edges of an article so that the space above and below the article is unobstructed and forcing the articles down into the box with a force greater than that due to gravity to prevent free fall thereof. As shown in Fig. 1a, articles are fed by individual conveyer belts to a collating station 13 having sensing switches to stop a belt 10 when a packet arrives at station 13, the belts being restarted when each has a packet at station 13, to pass the packets on to belt 14 of the supply station. Their movement is stopped by plate 15 and the clamp plates 16 engage the sides of the packets by moving towards the central position to position 16a (see also Fig. 2, not shown). Plate 15 is then raised by cylinder 20 and the clamped articles moved to a position over open box 21, Fig. 1b. They are then forced downwardly into the box by plunger 30 having platens 32 on which is mounted an arcuate wire section so that both packets are engaged simultaneously thereby if two rows of packets are to be boxed (Fig. 3, not shown). The machine may box individual articles or articles in rows (as in Fig. 3).

A twin-turbine torque-converter drive of a shovel loader has a first turbine 18, driving an intermediate output shaft 44 through a lowspeed gear pair 38, 40 and a fluid-pressureengaged friction clutch 46 controlled by a dragring valve, Fig. 3, so that the clutch overruns when speed and load conditions are such that a second turbine 20 is able to drive the shaft 44 through a high-speed (preferably overdrive) gear pair 48, 52. The intermediate shaft 44 drives a final output shaft 72 through the connected suns of two sun-ring-planet trains which provide reduced, reverse, and direct drive by brakes 80, 63 and clutch 86 respectively. An input driven power take-off 34 is also provided. One-way clutches.-The low-speed turbine clutch 46, Figs. 2, 3, comprises a piston 96 in a cylinder 94 bolted to the input wheel 40 and applying engaging pressure, in opposition to a disc-spring 106, to clutch-discs 46 connecting the input wheel 40 to a clutch output hub 88, which has a lost-motion spline connection 112 with the shaft 44 which it drives. When the wheel 40 tends to drive the shaft 44 forwards (counterclockwise, Fig. 3), pressure fluid is supplied to the clutch cylinder 94 through shaft passages 105, 104 and an aligned port 102 in the hub 88. When the shaft 44 overruns the hub 88, the spline clearance is reversed and the port 102 disaligned with supply 104 and exhausted through the spline clearance. Relative rotation in the drive direction, to re-align the ports 102, 104, is produced either by a spring-loaded drag plunger 92 or by the friction discs 46 alone, A ball valve 110 exhausts residual pressure in the clutch cylinder.

Abstract: 1,259,652. Producing glass fibres. OWENSCORNING FIBERGLAS CORP. 18 Sept., 1969 [18 Sept., 1968], No. 46070/69. Heading C1M. In a method of producing glass fibres in which glass is flowed from a feeder 11 through one or more orifices 12, the environment of the zone adjacent the fibres 16 and feeder 11 is controlled e.g. by controlling the temperature of the zone and protecting it from air currents by means of liquid or gas cooled shields 28, and the effectiveness of such control is monitored and the amount of heat supplied to the feeder regulated, such that loss of environmental control results in a reduction in the amount of heat supplied to the feeder. The temperature of the feeder is regulated by detecting the temperature thereof using a thermocouple 72 connected to a controller 73, the controller comparing the actual temperature with a desired temperature and adjusting the output of a transformer 70 which supplies electric current to heat the feeder accordingly. The loss of environmental control may be detected by a rate of change detector 80 which forms part of the controller which in the event of the thermocouple indicating a rate of change of temperature exceeding a pre-determined amount, activates a switch CD thereby enabling a device 81 to bias the controller to a lower desired temperature to compensate for loss of control. The switch CD may also be activated by a limit switch activated by the pivoting of a shield 28 out of its operative position, or by means responsive to a reduction of the flow of the liquid or gas cooling medium.

Abstract: 1,264,770. Frequency generators; radio navigation. STANDARD TELEPHONES & CABLES Ltd. 3 Dec,. 1970, No. 57457/70. Headings H3F and H4D. The invention relates to the generation of frequency related signals (e.g. 90 and 150 Hz) having predetermined constant phase relationships and constant equality of amplitude, more particularly tones used in aircraft instrument landing systems. The frequencies are generated from the output of oscillator 101, operating at a multiple (480 Hz) of the sum of the two frequencies: this is passed through a limiter 102 and used to drive a JK flip-flop 103, dividing x 2 and giving two outputs having a 180 degrees phase relationship with each other. The outputs of JK flip-flop 103 drive two further JK flip-flops 104, 105 each dividing x 2: the resulting four 120 Hz outputs have phase relationships 0, 90, 180 and 270 degrees amongst themselves. One output of JK flip-flop 105 is passed via 120 Hz bandpass filter 109 and amplifier 113 to one input of multiplier 117. One output of JK flip-flop 104 is similarly passed via 120 Hz bandpass filter 112 and amplifier 116 to one input of multiplier 118; it is also passed to JK flip-flop 106, dividing x 2. The outputs of JK flip-flop 106 drive two further JK flip-flops 107, 108 each dividing x 2, to give 30 Hz outputs which are passed by bandpass filters 110, 111 respectively and amplifiers 114, 115 respectively to the second inputs of multipliers 117, 118 respectively. The outputs from multipliers 117, 118 comprise 90 Hz and 150 Hz signals with the desired phase relationships, and these are passed via amplifiers 119, 120 respectively to amplitude modulator 125, producing carrier and sidebands, and to balanced modulator 126, producing sidebands only. A variable gain amplifier 124 precedes the filter 110 and is used to adjust the 30 Hz signal to multiplier 117, if required, in response to a feedback signal. The output from amplifier 120 is also applied to amplifiers 121, 122 the outputs of which are respectively in-phase and out-of-phase with their inputs. The outputs from amplifiers 121, 122 are summed by potentiometer, the signal on the adjustable wiper being adjustable between 90 Hz - 150 Hz predominating and - 90 Hz + 50 Hz predominating: this is added to the 90 Hz + 150 Hz output of amplifier 119, giving a means of adjusting the relative amplitudes of 90 Hz and 150 Hz at the output.
