Patent GB-1206147-A (GB)
Title: Improvements in and relating to method of and apparatus for carburizing
IPC: C23C8/22
Filed: 1967-12-27
Abstract: 1,206,147. Continuous heat treatment furnaces. BRITISH FURNACES Ltd. (Midland Ross Corp). 27 Dec., 1967, No. 58750/67. Heading F4B. [Also in Division C7] Ferrous metal work (e.g. gears) is carburized by passing it successively, e.g. placed on pallets on a conveyer, through longitudinally extending and aligned heating, carburizing and diffusing zones 25, 26 and 27 of a furnace 10, in which a carrier gas incapable of carburizing the work is introduced into the heating zone 25 to flow in the direction of work movement into the barburizing zone 26 and prevent flow of atmosphere therefrom to the heating zone, and an enriching gas containing hydrocarbon is introduced into the carburizing zone in a proportion to provide a carbon potential of 0À6 to 1À4% on mixing with the atmosphere, and atmosphere is withdrawn from either the carburizing or diffusing zones at the sum of the rates at which atmosphere is introduced into the several zones. The heating zone is maintained at between 1350 and 1800‹ F., e.g. by using radiant heating tubes. Where atmosphere is withdrawn from the carburizing zone 26, e.g. via an effluent opening 41, a mixture of a carrier gas and an enriching gas is introduced into the diffusing zone 27 in proportions to provide a carbon potential of between 0À6 and 1À1% and at a rate sufficient to cause a flow of the mixture toward the carburizing zone. Alternatively, where atmosphere is withdrawn from the diffusing zone 27 (e.g. via an effluent opening 43, Fig. 6), an oxidizing gas, such as air, H 2 O and/or CO 3  with or without a neutral gas e.g. a carrier gas, is introduced into the diffusing zone, the rate of atmosphere withdrawn therefrom being sufficient to cause atmosphere to flow from the carburizing zone. The enriching gas may be natural gas, methane, propane or oxyhydrocarbon. The carrier gas has the volume composition: 12-25% CO, 15-50% H 2 , traces of CH 4 , H 2 O and CO 2 , and balance at least 20% N 2 . Preferably the atmosphere in the carburizing and diffusing zones is circulated by fans 33 and 34 in the furnace side wall 19 to pass transversely into intake openings 35 and 38 down through passageways 36 and 39 outside the zones and back through discharge openings (37 and 40, Fig. 1) near the furnace bottom below the conveyer. The carburized work may be subsequently quenched. Upper radiant tubes (30, Fig. 1) are disposed above the work and lower radiant tubes (29) are disposed between transverse walls supporting known converging means, e.g. rollers or tracks for the work carrying pallets. The radiant tubes may be gas fired or electrically heated and may be individually or zone controlled.

Abstract: 1305170 Disposable umbrellas NAKANIHON SANGO CO Ltd 29 Dec 1971 [30 Dec 1970 4 May 1971(3)] 60301/71 Heading A4P A disposable umbrella comprises ribs 10, a cover 14, a hollow stick 1, a handle 17, a slider 3 having parts (6), Fig.3 (not shown), receiving the inner ends of the ribs, the ribs being substantially normal to the stick axis when the umbrella is open and means being provided to retain the umbrella in the open position. The cover is attached to the stick by engagement between a cap 16 and a member 2 having hooks 2b to which are attached elastic strings also attached to the outer ends, or intermediate points, on the ribs to urge the ribs upwardly until strings 8 become taut. The cover is attached to the ribs between pieces (13), Fig. 5 (not shown) on the rib outer ends and inserts 15 received in the pieces (13). The umbrella is retained open by an elastic string 19 extending between a hook 18a of handle 17 and a projection 5 sliding in a slit in the stick 1, which is of square crosssection. The umbrella is retained closed by engagement of the rib outer ends in a slidable ring 22. Sideways movement of the ribs is restricted by abutments (12), Fig. 3 (not shown)  on the slider 3 between adjacent parts (6). In a modification, the strings 21 are omitted. In a second embodiment, Fig. 7 (not shown), the slider is almost as long as the stick 1 and the umbrella is retained open by engagement between a catch on the lower end of the slider, or on the handle, and a projection on the handle, or on the lower end of the slider respectively. In a third embodiment, Figs.8 and 9 (not shown), the umbrella is retained open by engagement of a ball (46) in a hollow (45) in the lower end of the handle, the ball (46) being connected to an inward projection (5) of the slider by a string (47) and to a pull ring (49). When the umbrella is open, the lower part of the string (47) passes through a slot (44) in the handle, and to close the umbrella the ring (49) is pulled to pass the ball (46) from hollow (45) into a through-bore (43) of the handle, the bore (43) communicating with the slot (44), the umbrella then being automatically closed by means of an elastic string (50) extending between the projection (5) and a cap (40) attaching the cover to the shaft. In a modification, Fig. 10 (not shown), the strings 8 are omitted and abutments (12) between adjacent parts (6) on the slider supporting the rib inner ends allow substantially no sideways movement of the ribs 10 when the umbrella is open with the ribs normal to the stick-axis, which position is defined when shoulders on the parts (6) substantially abut the slider 3. The cover 14 may be made of vinyl plastics, and the stick, handle, slider and the pieces (13) may be made of synthetic resin.

Patent GB-740144-A (GB)
Abstract: 740,144. Variable-speed gearing. PRINCE, D. C. July 12, 1954, No. 20286/54. Class 80(2) [Also in Group XIII] Output pulleys 46, 50 are driven by a common electric motor M through variable-speed gearing so controlled by a thermostat T that, for a given change' in temperature, the change in speed of pulley 50 is greater than that of pulley 46. Shaft 44 of pulley 46 carries a sheave 42 having a central movable sheave portion between outer fixed sheave portions, V-shaped belts 40, 52 running between the movable and fixed portions. The shaft 44 is rocked about an axis 62 by a reversing motor MS to tension one belt and slacken the other so changing the ratios. Upon rise in temperature the thermostat T makes contact C1 to energize one winding of motor MS, to slow down the pulleys 46, 50. Upon fall in temperature, contact C2 is made to energize the other winding to speed up the pulleys 46, 50. Upon only a slight fall in temperature a heater R causes the thermostat to break contact C2 before any substantial rise in speed has occurred.

Title: Process for preparing solutions of curable urea- formaldehyde resins
IPC: C08L61/24
Filed: 1978-07-31
Abstract: The invention provides a process for preparing solutions of curable aminosulphonic acid-modified urea- formaldehyde resins. These solutions are prepared according to a known process modified by adding, in the initial reaction stage, 1-10 wt%, based on resin solids of an emulsion or suspension of a polymer derived from monomers of formula   <IMAGE> wherein R<1> is H or CH<3>, R<2> is O, R<3> is OH, NH2, OCnH2n+1, OCmH2mOH or OCmH2mOCnH2n+1, wherein m is an integer from 1 to 6 and n is an integer from 1 to 4, or R<2> and R<3> conjointly are N. The solution formed by this process is suitable for impregnating and coating carrier webs, the resin then being cured. Such treated carrier webs are particularly useful for application to a surface of a wood-based sheet in, for example, a quick-cycling press or a multi-daylight press resulting in improvement in properties of the surface of the wood-based sheet.
