Filed: 1927-12-08
Abstract: 295,168. Lehmann, A. Dec. 8, 1927. Packing cottonwool.-Cottonwool is packed in a paper &c. bag 28, Fig. 1, in zig-zag layers 32. The packing is effected by rollers 13, 14, Fig. 9, which feed the cottonwool 29 intermittently in a horizontal direction and move vertically so as to dispose it as shown in a frame 25 over which the paper bag is placed. In the machine shown in Fig. 10, the cottonwool 29 is fed by rollers mounted on spindles 12, 16 in bearings in a frame 9 vertically reciprocated by an adjustably mounted connecting rod 5. A gear 20 on the spindle 12 meshes with a fixed rack 21 and transmits motion in one direction to the spindle by rack and pawl or free-wheel mechanism. The rollers are geared together and a similar rack is mounted on the opposite side of the other end of the spindle 12. As the frame is reciprocated, the rollers intermittently feed the cottonwool. On reversal of the movement of the frame, a short interruption of the feed takes place owing to lost movement of the pawls. The table 22 carrying the frame 25 is vertically adjustable.

Filed: 1958-10-17
Abstract: 892,668. Moulding sheets from magnesium cement. TECTUM CORPORATION. Oct. 17, 1958 [Oct. 28, 1957; Jan. 9, 1958], No. 33268/58. Classes 22 and 87(2). A magnesium cement with a fibrous filler e.g. wood wool, bagasse, straw or synthetic fibres, is steam cured, whilst compacting it between moving belts. Fibres 1 are formed into a mat on a belt 3, sprayed with cement at 4, and delivered to the nip between perforated stainless steel belts 6, 7 backed by cast iron platens 8, 9. Steam is fed through a pipe 11 into a manifold 10, through the perforations on the lower belt, the moulding material, the upper belt, and out through the exhaust manifold 12. The belts are tensioned by hydraulic cylinders 26 acting on the driving rollers 23. Additional support for the lower belt is provided by rollers 27, 29. The upper belt is carried by a frame 33 which is adjustable vertically by threaded shafts 36. The distance between the belts is kept constant during their passage through the press by locking members 77 on endless conveyers 76. The locking members are moved into and out of operative position by a ratchet handle 94, and they are locked in the operative position by levers 99 operated by a handle 110. The whole machine is arranged in a container 125 through which hot air is circulated to prevent condensation of the steam. The cement may be magnesium oxysulphate or oxychloride cement. The ratio of binder to fibre may be 70 to 30, to 30 to 70, respectively. In a particular example the composition comprises (parts in grams):- Wood fibre (20% moisture) 448, MgO 284, MgSO 4 , 7H 2 O 153, and water 435. The curing time may vary from 30 seconds to 5 minutes.

Title: Improvements in or relating to weighing machines
Inventor: HENDRICK WILLIAM ALFRED FINCHE
IPC: G01G19/22
Filed: 1957-10-25
Abstract: 849,314. Photo-electric control of weighing apparatus. BERRY & WARMINGTON Ltd. Jan. 22,1959 [Oct. 25, 1957], No. 33317/57. Class 40(3). [Also in Group XVIII] Photo-electric cells 15 and associated lamps 20 adjustably positioned with the aid of pointers 16 at desired readings around the scale in a dialtype weighing machine co-operate with a drum 18 mounted on the pointer spindle 17 and having a peripheral aperture coincident with the pointer 19 to furnish electrical impulses to control the opening and closing of feed gates or valves supplying substances to the weighing pan or hopper of the machine. Connections to the cells and lamps are made by cables 23 which extend via plugs 23a to sockets 21b carried by a centrally positioned housing 21 supported on a cable conduit 22. The cells and lamps are supported by brackets 14 from a circular channel member 13, the brackets being so constructed (see Fig. 5, not shown) as to permit the Sells to be offset relatively to the pointers to compensate for the amount of material, in transit at the moment of controlling the feed gates or valves. Additional photo-electric cells 15a may precede the main cells 15 and serve to reduce the amount of material being fed to the machine just prior to the cut-off point. A further photo-electric cell 30 is associated with the zero position on the scale to prevent initiation of operations until the machine has been adjusted correctly. In a modification, Fig. 6 (not shown), lamps 20 individual to each photo-electric cell are replaced by a single lamp supported at the centre of drum 18 by housing 21. Reference is also made without giving details, to a construction in which the photo-electric cells, instead of being adjustably mounted on a circular member 13, are carried by radial arms adjustable by knurled knobs grouped coaxially at the centre of the dial.

Title: Power assisted controls for aircraft
IPC: B64C13/00
Filed: 1946-11-11
Abstract: 618,670. Power-assisted aircraft controls. MOSS, N. Nov. 11, 1946, No. 33465. [Class 4] [Also in Group XXXVII] In a power-assisted aircraft control system a pushpull member operated by the pilot is arranged to divide the load in constant proportions between the pilot and a reversible motor. In the form shown, the push-pull rod is in two portions 1, 2, the adjacent ends of which are formed with screw-threads 3, 4 of the same hand but different pitch, and connected by a housing 8. The rod portions 1, 2 are connected to the pilot's control member and the control surface, respectively, and the pitch of the thread 4 is less than that of thread 3. The housing 8 is carried by a bearing 10 in a member formed with racks 9 engaged by pinions 12 on a cross-shaft 13 carrying a worm wheel 14 driven by a worm 15 on a reversible direct-current motor 16. As shown in Fig. 3, power for the motor 16 is supplied by a separately excited opposed field generator 17 driven at constant speed, the motor torque being varied by regulating pile resistances 18 in the generator field circuits. The resistances are controlled by an arm 21, carried by a sleeve mounted on a fluted portion of the housing 8. The rod portions 1, 2 are prevented from rotating by pin and slots 5, 6, so that the initial movement of the pilot's control member produces equal forces in the members 1, 2, resulting in an unbalanced torque being applied to the housing 8, thereby rotating it and the member 21 to energize the motor 16 and move the control rod through the racks and pinions 9, 12. The motor ceases to operate when the ratio of the loads in the members 1, 2 is equal to that of the pitches of the threads 3, 4, the unbalanced force being taken by the racks and pinions. Trimming may be effected by adjusting the arm 21 through a linkage and trimming wheel. A hydraulic motor may be used instead of an electric motor.

Title: Improvements relating to the surfacing of roadways
IPC: E01C11/24
Filed: 1934-11-23
Abstract: 441,575. Roads; treads. RANDS, F. C., and ALEXANDER, T. F. N., Windsor House, Kingsway, London. Nov. 23, 1934, No. 33708. [Class 20 (iv)] Roads surfaced with asphalt, tar-macadam or bitumen macadam, or grouted or dressed with bitumen, tar or a bitumen tar compound, are roughened by subjecting them to heat. In the case of roads which have become slippery owing to an excess of binder, the heat is applied until the excess binder has carbonized and become inert to a depth to produce the required rugosity, the carbonized residue being left m place or removed by brushing. Alternatively, the heat is applied for a sufficient time to soften or liquefy the excess binder which is then brushed away, thus exposing the aggregate and providing interstices in the surface. The latter process may be followed by the application of a new surfacing material which is applied while the heated surface is still soft and plastic, or the heated surface may be treated with a solvent in the manner described in Specification 343,523. In the case of roads which do not contain any excess of surface binder, the heat is applied so as to carbonize the top skin to a depth not exceeding <1>/16", and the surface is then brushed. The heating process may be carried out by the machine described in Specification 430,403.

Abstract: 1,034,289. Continuous casting-machines; rolling; forging. CONCAST A.G. Aug. 18, 1964, No. 33775/64. Headings B3F, B3H and B3M. In a continuous casting process the casting is withdrawn from the mould into shaping tools whilst the core is still liquid and deformed without changing the peripheral length of the changing cross-section. The casting mould 1 is mounted on a reciprocable table 4 and may have a rectangular cross-section, or as shown in Fig. 10 to partially preform the casting which is further deformed by roll passes 16-20 to form a number of bars connected by thin webs which may be cut by rolls 32 or burners 34. In a modification, Figs. 16, 17, the liquid-core casting is shaped by a tool 44 mounted beneath the mould on a table 80 which is vertically reciprocated by a cam 45, springs 51 urging the table to its upper position. The tool comprises two halves 56, 58 shaped to form the indentations in the casting and pivotally mounted at the upper ends on bearings 64, 64. The tool is opened and closed in synchronism with the up and down reciprocatory motion of the table by the rotation of threaded discs 96 on shafts 98. Springs 104 bias arms 102 connected to the discs 96 to the position in which the die-halves are open. On downward movement of the tool, arms 100 strike resilient stops 108 to cause the die halves to close. The opening and closing of the tool may alternatively be achieved by hydraulic means, a valve being actuated by cam means, during movement of the table.

Filed: 1972-07-19
Abstract: 1396365 Heart pacemakers AMERICAN OPTICAL CORP 19 July 1972 [19 July 1971] 33825/72 Heading A5R [Also in Division H3] A heart pacemaker has a pulse generator providing stimulating pulses on electrodes E1, E2, the generator including means for varying the pulse width to automatically maintain the energy in each stimulating pulse at approximately a constant predetermined energy irrespective of power supply output variations. The pacemaker is of the type disclosed in Specification 1266907 but with the addition of components 100-103 and T100. A capacitor 57 charges up, unless the pacer is inhibited due to conduction of transistor T6 to discharge capacitor 57 until its potential is such that transistor T7 conducts and capacitor 57 discharges through resistor 37 and transistors T7 and T8 until the potential on capacitor 57 is insufficient to keep T7 conducting. Conduction of T7 and T8 results in discharge of capacitor 65 through transistor T9 and through the patients heart. The stimulating pulse width depends on how long transistor T7 is conducting which depends on -how rapidly capacitor 57 discharges. A resistor 103 monitors the battery supply output voltage and biases transistor T100 in dependence on this output. Capacitor 57 discharges partly through transistor T100, the effective resistance of which increases as the battery output decreases thereby increasing the stimulating pulse width with decreasing battery voltage to maintain the pulse energy approximately constant. The biassing of the transistors T7, T8 may be modified by using diodes (8, 10), Figure 2 (not shown), in the manner disclosed in Specification 1328926.

Abstract: 1463814 Measuring fluid-flow NATIONAL RESEARCH DEVELOPMENT CORP 10 July 1974 [17 July 1973] 33934/73 Heading G1R [Also in Division A5] A flowmeter for measuring the peak flow-rate of a single forced expiration comprises a rod (40) mounted in a cylinder 10 along its axis, with the threaded end (41) of the rod engaging a tapped bore (24) Fig. 2 (not shown) in a first end member (20) of the cylinder and the non-threaded end of the rod engaging by a friction fit a bore (34) of a second end member (30) of the cylinder, a piston 50 slidably mounted on the rod adjacent the threaded end portion (41), with a coiled tension spring (60) engaging threads on the piston and a diametral end (61) of the spring engaging a diametral hole (42) in the rod so that the spring offers resistance to the movement of the piston away from the first end member, and a spring-loaded indicator stud so projecting through a slot 15 of uniform width in the cylinder and provided with a non-linear scale 17, the plate 81 of the stud so serving as an indicator. When the patient effects a forced expiration into a mouthpiece (not shown) connected to the hollow tapered portion of a boss (22) of the first end member (20), the expired air passes through a circular array of apertures (24) in the member (20) to displace the piston, and along with it the indicator stud; and on termination of the expiration the piston returns under the spring action but leaves the indicator stud positioned to mark the peak air-flow relative to the scale. In a modified embodiment, one end member is formed integrally with the cylinder, the end members being apertured to enhance air-flow therethrough, and the slot is opened up at the separable end to facilitate insertion of a spiral indicator formed from a metal blank with end portions (91, 92) of greater width than the slot. The end portions are connected by an integral strip (93) passing through the slot. All parts, except the spring, can be plastics mouldings.
