Title: Instruments for measuring the set and temporary compression of a pile or the like during driving
IPC: E02D13/06
Filed: 1937-02-10
Abstract: 490,223. Strain gauges. PIMM, G. B. R. Feb. 10, 1937, No. 3984. [Class 106 (ii)] An instrument for measuring the set and temporary compression of a pile during driving comprises two members one of which is moved on downward movement of the pile by the set plus the temporary compression and one or both being moved on recovery of the pile by an amount corresponding to the temporary compression so that the positions of the members give both set and temporary compression. A standard 22 mounted on a base 23 by means of a ball joint 24 carries by means of adjustable clamps 21 the casing or guide member 1 in one face of which a slider 2 is longitudinally mounted. A cursor 3 is also mounted to slide on the same face of the member 1. A knob 6 enables the slider 2 to be moved relative to the guide. Scales are provided on both slider and guide. The cursor embraces the front of the guide 1 grooves 9 in which it engages by tongues 8. A pointed bent spring 11 is located in a slot 10 on the cursor and a similar spring 18 located in a slot in the casing. Two arms 15 project on each side of the casing and these are engaged in slots in plates 16 clamped to the pile 17. When the pile receives a blow, the cursor is moved down relative to the guide 1 by the sum of the permanent set plus the temporary compression. As the pile recovers from the temporary compression, the spring 11 carries up the slide 2 by this amount which may be read on the scale on the slider 2. The permanent set may be read off by noting the positions of the cursor on the scale on the guide 1 before and after the blow. A button 14 on slide 12 serve to release the spring 11 for cursor movement. A screw 20 may be used to clamp the device in any position reached. In a modification, a pointed member fixed to the pile projects through a slot in one slide member to engage a second slide member. In a further form, a rack is moved by the pile and engages a pinion fixed to a shaft on which is a pointer. A second pointer is mounted on a hollow shaft surrounding the first shaft and connected to it by a one-way clutch.

Title: Repeater for receiving and transmitting data signals
IPC: H04L7/00
Filed: 1977-02-01
Abstract: 1535892 Regenerative repeater NCR CORP 1 Feb 1977 [12 Feb 1976] 04018/77 Heading H4P In a regenerative repeater, incoming data is decoded and stored in shift register 210, local clock signals passing to encoder 220 only after detector 212 detects a predetermined pattern of stored preamble and synchronization bits, whence data from shift register 210 is encoded at 220 and transmitted after amplification in transmitter 222. Clocking for shift register 210 is derived from oneshot 206 prior to detection of the predetermined pattern, whence shift register clocking is controlled by the local clocking signals. The data comprises 40-bit characters, and, once the predetermined pattern is detected, counter 216 ensures that the transmitter 222 is enabled only for 44 bits, thus improving the repeater's immunity against noise. The incoming data, equalized at 200, passes to zero crossing detector 202 whose differentiated output triggers the non-retriggerable one-shot 206, of 3/4-bit pulse duration, leading edges of the one-shot pulse ouput enabling the sampling of the zero crossing detector output by decoder 208. Thus only significant zero crossings are decoded and passed to shift register 16, the data being transmitted with 0, 1, represented as a transition to 0, or 1, respectively in mid-bit. The local clock comprises oscillator 215 and dividers 218, and, when enabled controls the shift register 210, encoder 220 and counter 216. The circuitry is disclosed in detail in relation to Figs: 4, 5A, 5B and 6 (not shown). The repeater is incorporated into a path between a plurality of remote data terminals, e.g. cash registers, and a central processor, see (112), Fig. 1 (not shown). Arrangements in the path (116) form the subject of Specification 1,535,893.

Abstract: 992,174. Bearings; toothed gearing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 24, 1964 [Jan. 31, 1963], No. 4027/63. Headings F2A and F2Q. [Also in Division G1] A shaft 10 having flanges 14, 15 is mounted in a " keyhole " shaped aperture 16 of a plate 1. The aperture 16 has a portion 16a through which a flange 14 or 15 of the shaft 10 can pass and has a portion 16b which receives a portion 13 of the shaft 10. The flanges 14, 15 abut the plate and the shaft 10 is urged towards the portion 16b of the aperture 16 by a spring 17 which is riveted to one side of the plate, is passed through the aperture 16 and has a turned-over end retained in a hole in the plate, or alternatively retained by another rivet. A " knee " portion 17a of the spring 17 ensures that the force exerted acts jointly on the flanges 14, 15 of the shaft 10 and thus prevents tilting thereof. In an embodiment, the plate 1 carries a brake magnet assembly having a magnet 2 in a clamp 3 pivotally connected to the plate 1 by a pin 4. The clamp 3 is locked by a threaded pin 5 which passes through an arcuate slot 6 in the plate 1 and has a nut 7 thereon. A quadrant gear 8 is secured to the clamp 3 and meshes with a pinion 9 on the shaft 10 which can be rotated by a knob 11 when the nut 7 has been released. Over-meshing and back-lash is said to be eliminated due to the gear 9 being resiliently urged towards the quadrant gear 8 by the spring 17.

Title: Improved means for controlling the pitch of the blades of a helicopter rotor
IPC: B64C27/54
Filed: 1944-03-06
Abstract: 572,081. Helicopters. FAIREY AVIATION CO., Ltd., and TIPS, E. O. March 6, 1944, No. 4143. [Class 4] The blades of a helicopter rotor are cyclically varied in pitch by rods extending between arms on the blade roots and a tiltable member rotating with the rotor, an axial extension from the tiltable member being engaged by a plate displaceable in any direction in its own plane by means of either or both of two levers tiltable about axes at right angles to one another. The plate is also displaceable axially to effect simultaneous adjustment of the pitch of the blades. The blades of the rotor can flap about a spherical bearing a on a shaft b within a spherical housing c fast on the shaft b, the root anchors d of the blades passing through guide slots e in the housing c which engage metal-sheathed rubber bushes f on the root anchors d. Spherical thrust plates g on the anchors d are movable relative to the housing c on ball bearings h. Levers j, Fig. 2, extend laterally from the root anchors, the outer ends of the levers being on the flapping axes of the blades. The outer ends of these levers are connected by ball-ended rods k to a member m tiltable about a spherical bearing p slidable upon the shaft b. Jointed links n, o constrain the member m to rotate with the housing c. A conical extension q from the member m is engaged by a spherical bearing s in a cylindrical extension t on a plate u. This plate is of hollow box construction and is supported by ball bearings v upon a disc w which has a hub x screwed upon a fixed tubular member y. A cable 11 wound around the hub x enables the latter to be rotated to raise and lower the plate u and member m to adjust the pitch of all the blades simultaneously. The plate u is movable in its own plane to tilt the member m by two levers 20, 21 engaging split bearings 22, 23 slidable in vertical tubes 24, 25 secured to the plate u.. The levers 20, 21 are movable about two axles 18, 19 at right angles to one another by the worm gear shown, the lever 20 also being pivoted to its axle 18 by a pin 26 parallel to the axle 19 of the other lever. Actuation of the lever 21 consequently causes a diametrical displacement of the plate u and actuation of the lever 20 causes the plate u to swing about the upper end of the lever 21. The tubes 24, 25 allow for the relative vertical displacement of the plate u. In a modified form, the rods k pass through openings in the housing c to levers connected to the blade roots within the housing.

Abstract: 1461307 Centreless grinding M POSSATI [trading as FINIKE ITALIANA MARPOSS SAS] 29 Jan 1974 [9 Feb 1973] 4198/74 Heading B3D A method for checking the working conditions during machining in a centreless grinder, the workpiece 10, Fig. 1, being supported by support means 13, comprises generating a first measurement signal responsive to the position of the workpiece outer surface at a point close to the support means surface, generating a second measurement signal responsive to the workpiece outer surface at a point located diametrically opposite to the proceding point, processing the first and second measurement signals to obtain a third signal responsive to workpiece diameters, and comparing the first measurement signal with a reference signal to obtain a signal for monitoring the position of the support means surface. The grinder may be of the plunge machining type having a working wheel 11 and a feed wheel 12 between which is a knife 13 in a support 14. An electronic comparator 16 is mounted on a slide (21, Fig. 2, not shown) and has moving arms 17, 18 provided with feelers 19, 20 for gauging the size of the workpieces, the feeler 20 being adjacent the knife 13. Each feeler is associated with an inductive transducer, the output signals of which are fed to a summing unit to produce a signal indicative of the size of the workpiece and to control the machining operation. The signal from feeler 20 is also compared with a reference voltage and when higher than that voltage operates an alarm and a control unit which actuate a motor to raise the knife relative to its support and thus compensate for wear of the knife. The circuit may be operated so as to give a direct indication of the wear of the knife. The method may be applied to a grinder of the through-feed type having a working wheel 51, Fig. 4, and a feeding wheel 52 consisting of two parts 55, 56. The workpiece 50 is supported on a knife 53 between the wheels, and a head 57 of a comparator has a feeler disposed between the parts to measure the wear on the knife and a second feeler (not shown) on the other side of the workpiece. The method may also be applied to machines in which the workpiece is supported on a pair of shoes and rotated by a magnetic spindle.
