Title: Improvements in mop making machines
IPC: A46B3/00
Filed: 1929-05-18
Abstract: 332,677. Dehn, F. B., (Fuller Brush Co.). May 18, 1929. Binding and covering ; angular bending; stamping ; bending-dies ; shearing- adjuncts. - A machine for making mops comprises means for intermittently assembling a core and mop material to comprise a mop mass, means for intermittently positioning a grooved blank in co-operative relaytion with respect to the mop mass, and means for closing the sides of the blank together so as to secure the mass thereto. In the construction shown the blanks 21, Fig. 2, contained in a hopper 17 are fed singly by reciprocating pushers 18 into position beneath a die 23 which is adapted to bend each blank into trough-shaped form, as shown at 48. The blank 48 is then pushed off the lower die by spring- pressed pins and is moved transversely by a pusher 33, Fig. 1, which is moved indirectly by cam means on a shaft 32. Similar means is employed to move a feed block 58 which engages a wire 52, from which is formed the core of each mop, the wire and the blank 48 being moved in opposite directions. The mop material is caused to move in a path between the wire and the blank. The core passes above a punch plate 51 which is caused to reciprocate vertically, the upward movement of the plate raising the wire and doubling the mop material within the blank 48. The blank is bent round the mop material by means of pivotally-mounted spring-pressed formers 42 actuated through the medium of a downwardly-moving head block 39 and ribs 78 on stationary wire-shearing blocks 63. A lever 60 provided with a hardened bushing cuts the wire as the head block 39 descends. End formers 79, each pivotally attached to the end of a main former are provided for the purpose of closing the ends of the blank as shown at 81, Fig. 8.

Title: Transistor switching circuit
IPC: H03K17/66
Filed: 1973-04-03
Abstract: 1386547 Transistor switching circuits INTERNATIONAL BUSINESS MACHINES CORP 3 April 1973 [4 May 1972] 15794/73 Heading H3T A switching circuit comprises: transistors T1, T2 connected as a long tailed forming a current switch, with an input I1 connected to the base of T1 and the base of T2 maintained at a reference potential V4; further transistors T13, T14 connected as a single ended push pull output stage having direct coupling between their bases and the collectors of T1, T2, the output 03 being taken from the junction between T13, T14; and an active feedback path T3 from 03 to one of the current switch transistors. When the input I1 is at a low level, transistor T1 is off and transistor T2 is on drawing all the current of transistor T5, which is greater than that of transistor T4. The excess current is drawn from transistor T10 which clamps the collector of T2 to keep it out of saturation, and also keeps D3 and T11 conducting. Diode D4 is made conductive by the collector current of T12 and the base voltage of T10 becomes V6 plus the drop across diode D4. The base of T11 is clamped by the emitter of T10 to approximately V6. Transistor T15 therefore conducts to turn transistor T14 off. Transistors T8, T9 and diode D2 are also off. As transistor T1 is off, the collector current of T3 turns on transistor T13 and the output 03 is at a high level determined by clamp D1, V5. When input I1 is at a high level T2 is turned off and T1 conducts, being kept out of saturation by transistor T9 and resistor R4. The high level collector voltages of T2 and T4 turn on diode D2 and drive T11 to turn on T14 so that output 03 falls to its low level. The emitter voltage of T8 falls until T8 conducts diverting the current of diode D2 and limiting the swing of the collector voltage of T14. In a simpler circuit, Fig. 2 (not shown) the collectors of the long tailed pair stage are directly connected to the bases of the output transistors without any intervening transistors, and saturation of the transistor to which the input is applied (T15) is prevented by a current mirror (T19, T20).

Title: Method of and apparatus for foming articles from a strip shaped felt of fibrous material containing hardenable bonding material
IPC: D04H1/58
Filed: 1973-04-03
Abstract: 1430477 Curing resin bonded fibrous felt; after moulding FIBERGLAS CANADA Ltd 3 April 1973 [1 Feb 1973] 15855/73 Heading B5A [Also in Division F4] In a method of forming strips of resin bonded fibrous felt by pulling the resin impregnated felt through a forming die, the shaped felt is cured after exit from the forming die by flowing hot gas through the thickness of the felt. In the apparatus shown a split pipe insulator 31 is produced by pulling a resin impregnated felt 11 through a forming die, the apparatus comprising consolidating rollers 19, 20 where the felt is compacted, a reinforcement feed section 21 where a reinforcing tensile member 23 is applied to the underside of the felt, a "crisping" station 28 where the resin at the surface of the felt is at least partly cured, a guide channel 95 leading into a heated forming device 30 where the felt passes through the forming die and is aired by the hot gas, a gripper mechanism 33 for pulling the felt through the apparatus, and a cutter 38 for cutting the cured shaped felt into lengths. As shown in Figs. 4, 7, the forming device 30 comprises a die inlet cone leading into an annular gap 89 defined between a heated inner die 82 and an outer die 83. In use, the felt is gradually deformed by the guide channel 95 and cone 96 to the desired circularly shaped cross-section and is wrapped around the heated inner die 82, thus passing into the inlet end of the outer die 83. As shown in Fig. 7, the felt is heated as its passes through the annular gap 89 by gas burners fitted in openings 108 in the casing of the forming device. Heating is continued as the felt passes along the die 83 by recirculating the hot gases from the burners using a pump P, the die 83 being perforated with openings 84 to facilitate heating of the felt. The casing 60 around the central part of the heating apparatus is sealed, as shown in Fig. 4, from the casing 61 around the outlet portion of the apparatus, the pump P being situated in the chamber defined by casing 61 so that the hot gases extracted by the pump P are forced to pass through the felt via openings 84. The gripper mechanism (Figs. 8, 9, not shown) comprises electrically driven upper and lower conveyers (141, 142) carrying gripper plates (143) each formed with a V-shaped recess for gripping the tube. The frictional effect as the felt passes through the forming die is reduced by the partial curing of the felt surface at the crisping station 28-this reduces the tackiness of the felt. The crisping station comprises either gas burners which heat the felt directly or electrically heated plates (Fig. 2, 3, not shown). The dies 82 and 83 are readily removable to enable pipe insulations of varying diameters to be produced.

Title: Improvements in or relating to processes for the production of formed articles of hydraulic cement or mortar
IPC: C04B7/12
Filed: 1952-06-26
Abstract: In a process for the production of constructional elements of hydraulic cement or mortar, e.g. bricks, a mixture consisting mainly of natural or artificial puzzolana as the basic material and additions such as lime acting as activators is extruded to the required form from an extrusion press with utilization of the plasticity of the mixture.  When puzzolana is thus used its own properties are sufficient to produce the required plasticity. The term puzzolana includes both natural and artificial substances e.g. fine ground trass or fine ground blast furnace slag (other examples being mentioned), and activators which may be added to increase the binding power of the basic material are, for example, Portland cement and various limes.  Plasticity reducing materials, e.g. sand, may be used if required.  Rapidly cooled fine ground slags from crude steely irons do not need activators, and the mere addition of the requisite quantity of water results in a mixture suitable for extrusion.  The brick hardens by the setting of the mixture instead of being baked, as in the case of clay.

Title: Improvements in or relating to a method for raising plants from seed
Filed: 1934-05-30
Abstract: Plants are raised from seed, with or without the use of soil, by treating the seeds with a nutrient aqueous solution or suspension containing sulphocyanate in an amount not exceeding ,2 per cent of the solid content.  A sulphocyanate of an alkali metal or of ammonium may be used.  The nutrient medium may contain iodine salts.  A period of treatment with water may precede the treatment with nutrient medium.  The seeds may be shallowly planted in soil or treated as a layer one to three seeds thick.  The treatment may take place at a temperature of 18 to 30 DEG  C.  The liquid may be applied by spraying or irrigating.  In the latter case the level of the liquid is lowered as the rootlets grow so that only the tips of the rootlets reach the liquid.  The plants may be planted out in soil when the first leaves appear. The seeds while under treatment may be exposed to sunlight or ultra-violet rays.  One nutrient medium described contains potassium nitrate, sodium phosphate, magnesium sulphate, urea, ferric citrate, calcium sulphate and a mixture of lactose, glucose and saccharose together with sulphocyanide and iodine salts. Norwegian saltpetre is mentioned as an ingredient of a similar mixture.  Specification 9396/03, [Class 55], is referred to. According to the third Provisional Specification the nutrient medium may contain ammonia.
