Title: Heat exchangers apparatus for making debossed displays in blanks
IPC: F28F21/08
Filed: 1974-04-01
Abstract: 1461638 Heat exchangers DES USINES CHAUSSON SA 1 April 1974 [4 April 1973] 14427/74 Heading F4S In a brazed vehicle radiator core construction comprising a plurality of tubes 1 extending between end plates 2, a pair of flanged lateral side plates 4 bounding opposite sides of the core and extending between the end plates 2, and corrugated fins 5 extending between adjacent tubes and between the outermost tubes of the core and the lateral side plates 4, the connection between each of the outermost tubes and the adjacent side plate, with the interposed corrugated fin, in the regions immediately adjacent the end plates is non-rigid so as to permit relative expansion to take place between said lateral side plates and the outermost tubes when the core is subjected to a sudden large temperature increase, e.g. when hot coolant from the vehicle engine is initially passed into the cold radiator core; the risk of tube failure is thus greatly reduced. Various constructions permitting this expansion to take place are disclosed. As shown each flangeo side plate 4 is formed with a rib 6 in said regions thereby providing only a line contact along which brazing can take place with the adjacent fin (see also Figs. 12 and 13, not shown). Alternative constructions are as follows:- (1) Coating or screening the surface (8) of the side plate facing and contacting the adjacent fin with a material to prevent brazing taking place in this region (see Fig. 3). (2) Inserting a plate into a recessed portion of the side plate, which is not brazed either to the side plate or to the adjacent fin (see Fig. 4). (3) Providing a depending lug connecting the side plate to the tube end plate, the surface of the lug facing the adjacent fin not being coated with brazing material (see Fig. 5 and Fig. 11). (4) Suitably configuring the adjacent fin such that differential expansion occurring can be taken up by distortion of the fin (see Fig. 6). (5) Cutting through said adjacent corrugated fin in the regions adjacent the tube end plates so that the part of the fin brazed to the side plate can move relative to that part brazed to the adjacent tube (see Fig. 7). (6) Providing the side plate with several transversely extending slots to permit the plate to distort in this region (Fig. 8), or providing flanged transverse, inclined or chevron slots in the side plates, the flanges of said slots extending inwardly towards and bearing against said adjacent corrugated fin and being brazed thereto (Figs. 14 and 15). (7) Providing a plate coated with brazing material, which plate is received in a groove in said side plate, said plate being brazed to the adjacent corrugated fin and to said side plate during the brazing operation-the side plate however is not coated with brazing material (Fig. 9). (8) Coating only part of the side plate with brazing material (Fig. 10). (9) Screening that part of the outermost tube adjacent the end plates so that a brazing connection between the fin and the tube is not effected in this region (Figs. 19 and 20).

Title: Manufacture of 2-aminoindane compounds
Filed: 1954-05-17
Abstract: The invention comprises indan-3-ols substituted in the 1-position by an alkyl, aryl or aralkyl group and optionally by a second hydrocarbon residue, and in the 2-position by a primary, secondary or tertiary amino group.  These are made from 2-unsubstituted indan-3-ones bearing the appropriate 1-substituent(s) by conversion into the 2-isonitroso compounds and reduction, preferably by hydrogenation with Raney nickel in neutral or alkaline solution; 2-amino-indan-3-ones may be intermediates.  The aromatic nucleus of the indane and that in the 1-substituent may carry further substituents, e.g. alkyl or alkoxy.  The 2-amino group may be converted into -NR1R2, where R1 and R2 are hydrogen, alkyl or aralkyl or together form a ring which may contain further hetero atoms such as O, S or N.  In the examples: (1) 1-phenyl-indan-3-one is treated with butyl nitrite and hydrochloric acid to give 1 - phenyl - 2 - isonitroso - indan - 3 - one and the latter hydrogenated with a palladiumcarbon catalyst to 1-phenyl-2-amino-indan-3-one hydrochloride; addition of palladium chloride and further hydrogenation leads to 1 - phenyl - 2 - amino - indan - 3 - ol hydrochloride; the free base and its tartrate and sulphate are described; the reduction can be carried out in one step if palladium chloride is added to the catalyst at the beginning; (2) 1-phenyl - 2 - dimethylamino - indan - 3 - ol is obtained from the previous product by alkylation with formaldehyde and formic acid; (3) 1-phenyl - 2 - isonitroso - indan - 3 - one is hydro-genated directly to the amino-indanol with Raney nickel in methanolic sodium hydroxide; (4) 1 - methyl - 2 - amino - indan - 3 - ol (as hydrochloride) is obtained as in (3); (5) 1 phenyl-2-amino-indan-3-ol is converted into a Schiff's base with benzaldehyde and hydrogenated to give 1-phenyl-2-benzylamino-indan-3-ol; methylation of the latter as in (2) yields 1 - phenyl - 2 - benzylmethylamino - indan - 3 - ol (as hydrochloride), converted by hydrogenolysis into 1 - phenyl - 2 - methylamino - indan - 3 - ol (via hydrochloride); (6) 1-phenyl-2-piperidino-indan-3-ol is obtained (as hydrochloride) from 1 - phenyl - 2 - amino - indan - 3 - ol and 1:5 - dibromopentane; (7) 1-phenyl-1-methyl-indan-3-one is converted as in (1) into 1-phenyl-1-methyl - 2 - isonitroso - indan - 3 - one and 1 - phenyl - 1 - methyl - 2 - amino - indan - 3 - ol hydrochloride; (8) 1-methyl-2-dimethylamino-indan-3-ol is obtained as in (2); the hydrochloride is described.

Abstract: 514,796. N-aralkyl-p-aminophenols. DU PONT DE NEMOURS & CO., E. I., HENKE, C. O., and BENNER, R. G. May 16, 1938, No. 14589. [Class 2 (iii)] N-Aralkyl-p-aminophenols are prepared by hydrogenating p-aminophenol in the presence of an aromatic aldehyde, the hydrogenation being in neutral or slightly alkaline aqueous medium with a nickel catalyst at 50‹-150‹ C., preferably 60-75‹ C., and under a hydrogen pressure exceeding 100 pounds per square inch, preferably 400-500 pounds per square inch. The catalyst is removed by filtration, the filtrate made just acid, and the lower layer containing crude N-aralkyl-p-aminophenol separated and steam distilled to remove low boiling impurities. In an example, p-nitrophenol (from p-nitrochlorbenzene) is reduced by hydrogen in presence of a catalyst containing 25-30 per cent. reduced nickel on kieselguhr. The alkalinity of the charge may then be reduced by addition of an organic acid. Benzaldehyde is then introduced and hydrogenation continued. Steam distillation of the crude benzyl-p-aminophenol obtained, removes benzyl alcohol as a by-product formed by hydrogenation of excess benzaldehyde and leaves the pure product. Employing salicylic aldehyde, o-hydroxy-benzylp-aminophenol is obtained. p-Anisaldehyde yields p - methoxybenzyl-p-aminophehol ; cuminic aldehyde yields p-isopropylbenzyl-paminophenol and 4-methyl benzaldehyde yields 4-methylbenzyl-p-aminophenol.

Abstract: 650,497. Joining structural members. HENDERSON, R. May 31,1948, Nos. 14677 and 30338. [Class 20(ii)] Means for forming joints between metal channel members comprise a tongue member 5 passing through a pair of slots in a channel member, one in each flange, and within the channel member a U-shaped keeper 10 with its limbs 11 directed towards the web of the channel member, each limb 11 bearing against one flange or a reinforcing rib thereon, and being slotted to form two fingers 12 to engage slots 9 in the tongue member 5 to lock the latter in position, one end of the tongue member protruding through the flange of the channel and received in a slot 22 in a block 20 in the end of a second channel member butting against the said flange and the other end of the tongue member either protruding or not, as desired, to secure another channel member. An additional tongue member with.one end 14, or two ends 14, 14<SP>1</SP>, Fig. 13, may be secured in the first channel member by passing the tongue member 5 through a slot 19 therein and an end or ends may protrude through a slot in the web of the channel member or through the open side of the channel member or both and form means to secure another channel member butting against the outside of the web or normal to the open side of the channel member. The double ended additional tongue member is used in conjunction with a keeper as in Figs. 14 and 15, with a slot 31 for the tongue member and with its fingers 28 hooked to engage over the tongue member and its fingers 29 curved to facilitate withdrawal. Another form of additional tongue member 32 has an end projecting upwards from a block having a slot 34 through which the tongue member 5 passes and is used to secure another channel member in prolongation of the first channel member. The slotted block 20 has a hole in its top face to receive a boss 17 on the tongue member 14 and it has a hole through its side faces which, when the parts are assembled, is slightly out of line with a hole 18 in the tongue member. The boss 17 retains the tongue member in position until a tapered pin is driven through the slightly offset holes and urges the parts tightly together. The bosses 7 and holes 8 in the tongue member 5 serve a similar purpose. The first Provisional Specification mentions the provision of slots at intervals along the length of the channel member, reinforcing the channel members by a liner, making the block 20 by cutting metal strip or cutting extended metal, fixing paper-backed expanded metal to the channel, and positioning the channel members in various ways as members of a beam. Specification 650,520 is referred to.

Abstract: 1,025,850. Statistical apparatus. STANDARD TELEPHONES & CABLES Ltd. April 10, 1964 [April 13, 1963], No. 14880/64. Heading G4M. The invention resides in a device for changing from fast, continuous feeding of a record card to intermittent feeding. The card (not shown) enters from the left, and its leading edge cams down a lever 5 so that the left-hand end of a rocker bar 1 is lowered and presses the card on to a continuously rotating roller 4 which then advances the card. When the card reaches the right-hand end of the device, its leading edge rides up lever 20 and is lifted clear of a sprocket wheel 19. The leading edge of the card then engages a stop 28 which is forced back against abutment 27 and which actuates a switch 17 to energize solenoid 23. This solenoid lowers the right-hand end of rocker bar 1 to press the card down and engage one of its feed holes on a tooth of sprocket wheel 19. At the same time, the lever 20 is pressed down and closes a holding contact 21 for solenoid 23 before switch 17 is opened by the return of stop 28. A further switch 25 actuated by solenoid 23 is used to start a step-by-step drive mechanism for sprocket wheel 19. When the end of the card passes lever 20, the latter returns, opens switch 21 to de-energize solenoid 23 and rocker bar 1 returns to its initial position. If another card is inserted before the first has been fed out of the device, the new card is kept out of engagement with roller 4 by lever 5.
