Title: Improvements in or relating to the adjustment of facsimile transmitters
IPC: H04N1/00
Filed: 1955-10-28
Abstract: 795,011. Copying-telegraph transmitters. HELL, R. Oct. 28, 1955 [Jan. 12, 1955], No. 30913/55. Class 40 (3). In a facsimile transmitter circuit arrangement having a scanning device associated with an amplifier having its anode coupled by a capacitor with the grid of a keying valve, a reference voltage corresponding to the scanning of the background of the original to be transmitted is connected once, or a number of times, during the scanning of the original from the anode of the amplifying valve to the capacitor, whilst at the same time a predetermined negative voltage is connected to the grid of the keying valve so that the coupling capacitor is charged to a value corresponding to the background value of the anode voltage of the amplifying valve, the source of bias voltage being disconnected from the keying valve after the charging has been effected. The light beam reflected from a document 3 on a drum 1 is applied to a photo-cell 8 coupled to the amplifying valve 11 whose anode output is. fed via a capacitor 15 and secondary winding 19 of a transformer 20 to the grid 16 of a valve 17 having its anode circuit coupled to the output terminals 26 by a transformer 24. The primary winding 21 of the transformer 20 is connected to an A.C. generator 22 providing a suitable carrier frequency. During the scanning of a strip 4 corresponding to the background of the document 3, a contact 7 closed by a projection 6 on a cam 5 connects the right-hand plate of the capacitor 15 to a source 18 which applies a predetermined negative blocking voltage to the grid 16 of the valve 17, and allows the capacitor 15 to charge to a value such that during the scanning of the document the valve 17 is cut off by light reflected from the background. When dark portions are scanned, the rise of potential at the anode 14 of the valve 11 is passed by the capacitor 15 to the grid 16 of the valve 17 which conducts and applies an A.C. signal to the terminals 26. In a modification, Fig. 2 (not shown), the output from the valve 11 is applied during the scanning of the document to a resistance-capacity combination having a relatively long period and producing a measure of the average background brilliance. Contacts closed simultaneously with the contacts 7 apply the voltage of this capacitor to a capacitor corresponding, and connected similarly, to the member 15 of Fig. 1.

Title: Improvements in clocks
IPC: G04B15/10
Filed: 1930-10-16
Abstract: 362,091. Clocks. BOWELL, G. B., 20, Bedford Avenue, Barnet, Hertfordshire. Oct. 16, 1930, No. 30934. [Class 139.] Escapements.-A clock escape wheel is escaped in long and short steps by the pendulum and coacts with a pair of connected anchor pallets and a detached pallet which is obliquely inclined to the teeth of the wheel at the contact point and operates in conjunction with a force tending to give impulse to the pendulum. This force is preferably gravity but may be spring. A scape wheel 1 of fifteen teeth coacts with pallets 3, 4 of anchor 2 and pallet 5 of gravity arm 6 pivoted at 16 and having a weighted extension 14 which rests on a pin 7 carried on an arm 17 rigid with the anchor 2. An arm 8 loosely pivoted to the top of the pendulum 9 has an extension 10 coacting with pin 7. Arm 8 is adjustable by screw 11. In Fig. 1 the pendulum is moving to the right and the gravity arm 6 is giving an impulse to pin 7 and the pendulum. After zero position of the pendulum, pallet 5 meets a tooth, Fig. 2, and pallet 3 unlocks wheel 1 which moves forward on the long step until held by pallet 4. This movement raises pallet 5 and rocks arm 6 clockwise; this position, Fig. 3, is maintained until, on the return swing of the pendulum and at a little past zero position, the pallet 4 unlocks the wheel just as the pin 7 meets arm 6 and raises pallet 5 off the scape teeth. The scape wheel then moves forward on the short step sufficient to leave pallet 5 clear to descend during the impulse as above described. The escapement is particularly intended for use with the clock mechanism described in Specification 327,708, [Class 139, Watches &c.]. The escapement may be at a distance from the clock proper and connected thereto electrically.

Title: Improvements in bundling and banding machines
IPC: C10G17/06
Filed: 1926-12-08
Abstract: 291,813. Rayner, G. F., (Shoe Lace Co., Ltd.). Dec. 8, 1926. Labelling.-Relates to a machine for bundling shoe laces and the like and applying a wrapping band or label. Pairs of laces are placed by an operator with their ends engaging members 56 on shafts 54. The mountings of the shafts 54 are arranged to rotate about a shaft 51, during which rotation the shafts 54 are themselves rotated by bevel gearing to wind the laces into bundles. Labels or bands are removed from the base of a magazine 61 by a pneumatic separator and are carried round in an anticlockwise direction by one of a number of pairs of arms 58 past a moistening device 19 until they arrive opposite the laces to be enclosed, in position A. The magazine 61 is adapted to reciprocate on a frame 62 at each feed motion; and the shaft 59 on which the arms 58 are rotatable is mounted in a frame 60 pivoted at 52 and adapted to be oscillated at appropriate moments to move the shaft 59 to the right. Associated with each pair of arms 58 is mechanism for folding the label about each pair of laces. After the frame 60 has receded and the band has been applied to the article, an arm 69 strips the bundle from the arms 58 and moves them into position to be engaged by an intermittently rotated spoked wheel 70 associated with a curved rim 71, past which the bundles pass to a delivery table 72.

Title: Improvements in or relating to agricultural mowing machines
Inventor: WILLIAMS FREDERICK
IPC: A01D34/07
Filed: 1956-10-13
Abstract: 851,711. Mowing machines. HARRISON, McGREGOR & GUEST Ltd. Jan. 13, 1958 [Oct. 13, 1956], No. 31232/56. Class 6(3). A mowing machine which comprises a frame 11 mounted on tractor hitch-links 20, 37, 38 and has a cutter-bar 24 carried by inner and outer shoes is characterised in that one of the hitch-links 37 is universally-jointed to a lever 13 pivotally attached to the frame 11 at its rear end and a spring 16 is mounted between the lever 13 and the frame so that the reaction of the spring on the frame, when the mower is in its working position, causes a transfer of weight from the inner mower-shoe 33 to a wheel or skid 34 arranged on the side of the frame remote from the cutter-bar. The hitch-link 38 is jointed to a fixed bracket 12 on the frame and the upper link 20 is attached to a pivoted arm 17 on the frame, the opposite end of which can be adjusted by a turn buckle 21to tilt the mower about a transverse axis. The rest-positions of the lower hitch-links are also adjustable by turnbuckles 35, 36. The lever 13 is pivoted about a horizontal pin 14 and has a pendant tongue 15 abutting the spring. The tongue is attached by a link 45 to a lever 40 swingable about a pin 41 against the action of a spring 44, the lever being connected by a cable 42 to an arm 43 on the inner end of the cutter-bar assembly whereby the load carried by the outer mower-shoe (not shown), is also decreased. The cutter-bar assembly can break-back about a pivot 30, under excess loading, by the yielding of a strut 31 having an overload-release device 32. When the mower is lifted, the lever 13 swings upwardly until prevented by contact between the main frame and an upstanding abutment (not shown). The drive to the cutters is taken from the tractor via a jointed shaft 25, chaindrive 26, cone-clutch 27 and gearbox 28, the cone-clutch permitting interruption of the drive upon break-back.

Title: Feedback integrating system
IPC: H03M1/00
Filed: 1962-08-15
Abstract: 960,327. Electric selective signalling systems; binary electric integrating apparatus. UNITED AIRCRAFT CORPORATION, Aug. 15, 1962 [Sept. 14, 1961],No. 31292/62. Headings G4A and G4H. In an electrical integrating system an analogue input is converted into a digital representation by a closed-loop system, and the digital representation is integrated. In Fig. 1 an electrical analogue input to a resistor 12 is balanced by a feed-back voltage across a resistor 14 - the loop comprising integrator 10, integrator 24, analogue-to-digital converter 6 and digital-to-analogue converter 4- and the digital representation of the input analogue is integrated by repeated additions under the control of clock-pulses 40, the final result appearing in a register 58. The purpose of integrator 24 is to ensure that the integral of the feed-back signal actually equals the integral of the input analogue. (The feed-back signal obviously equals the input analogue when balance is achieved but this fact does not necessarily mean that their integrals will be equal). If the input analogue across resistor 12 is x and the feed-back voltage across resistor 14 is y then when balance is achieved the output of integrator 24 will be constant and its input will be zero. Thus the output of integrator 10, which is f(x-y)dt, will be zero, and hence Jxdt = fydt. In a second embodiment, Fig. 2, the analogue input is either an acceleration or an angular velocity, and it is balanced by a pulse train of appropriate mark/space ratio applied to a "forcing winding". The output of the accelerometer (or gyroscope for angular velocity) is an A.C. amplitude representing the integral of the input and corresponds to the output of integrator 10 of Fig. 1. This A.C. signal is demodulated 16c, integrated 24, and digitised by being compared 6b with a rampvoltage 6a symmetrically disposed about zero, and by counting 52a clock-pulses 42, 50 negatively before agreement is obtained and positively afterwards, this being under the control of a trigger 8a which also controls the mark/space ratio of the signal fed-back to the accelerometer. Thus counter 52c records the integral of the input analogue, and a second counter 52b, arranged to be reset at the beginning of each ramp-voltage, records its instantaneous value.
