IPC: C07C215/76
Filed: 1928-01-09
Abstract: 283,467. Vidal, R. Jan. 8, 1927, [Convention date]. Leuco indophenols and indamines; amino compounds. - The separation of amino compounds produced by reduction of the nitroso compounds of phenol, cresols, naphthols, and dimethylaniline, by means of aqueous alkali sulphide, is effected by the addition of ammonium salts. In examples, p-nitroso-o-cresol and nitroso dimethylaniline are reduced by means of sodium monosulphide and are separated by means of ammonium chloride or other ammonium salt. The separation of the products obtained by condensation, in the presence of alkali sulphide, of the said nitroso compounds with phenols, cresols, naphthols, and aromatic amines is also effected by means of ammonium salts. According to examples, nitroso compounds of phenol, o- and m-cresols, a- and #-naphthols, and of dimethylaniline are treated with phenol, cresols, naphthols. resorcin, hydroquinone, pyrocatechin, aniline and dimethylaniline in the presence of sodium sulphide, and the products precipitated by means of ammonium chloride. In place of the latter, ammonium sulphate may be used. When aniline, dimethylaniline or nitrosodimethylaniline is employed in the process alcohol is added. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter:- Sulphuretted dyes are produced by fusion with sulphur of both the amino compounds and the condensation products produced and separated as above described. In an example, the condensation product from nitroso-o-cresol and phenol is fused with pulverized sulphur. Treated with alkali sulphide, the product may be used in printing and dyeing processes. This subjectmatter not appear in the Specification as accepted.

Abstract: 1,023,177. Hydraulic jacks. M. L. AVIATION CO. Ltd. May 4, 1964 [Feb. 7, 1963], No. 729/63. Headings B8H and B8J. A self-contained hydraulic hoist for positioning heavy loads comprises an inner cylinder 1 with a closed lower end to which a load hook 16, Fig. 4 (not shown), is attached and an open upper end with a flange 4 slidingly sealed to an outer cylinder 2. The outer cylinder 2 is closed at the top by a block 13 carrying an eye 14 for a crane hook (not shown) and is sealed to the inner cylinder 1 by a sealing ring 3 through which the inner cylinder 1 slides. The space within the outer cylinder 2 is thus divided into two: a part 6 above and within the inner cylinder 1 and an annular part 7 between the two cylinders 1, 2. The inner cylinder 1 has a separating cylinder 8 sliding within it and sealed by seals 10, 11. Practically constant pressure is maintained on hydraulic fluid in the space 6 by a device comprising springs 43, 44 and a tube 46. To raise a load a lever 23, Fig. 2 (not shown) is used to actuate a double-action pump with a cylinder 18 and a piston 17 to force fluid from the space 6 to the annular space 7. Fine control is achieved by a single-acting smaller pump actuated by a lever 28 operating on a piston 26 sliding in a cylinder 27 formed by a hole in one end of the cylinder 18. A release valve 32, Fig. 1 (not shown) operated by a handle 31 is spring- loaded into a closed position and may be opened by a cam 34 to allow fluid to flow from the annular space 7 to the space 6. A safety valve 42 allows recirculation of fluid to the space 6 under overload conditions.

Abstract: 682,650. Preventing inductive disturbance. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 11, 1951 [Jan. 25, 1950], No. 821/51. Class 40 (iv). [Also in Group XXXV] In order to minimize the interference which may be produced in telephone lines by the presence of harmonics in an A.C. supply line adjacent thereto, a number of loads are arranged to draw currents which are so mutually displaced in phase that the harmonics arising in the supply line are substantially reduced by mutual cancellation. As shown, the loads are motors in separate traction cars C<SP>1</SP> ... C<SP>4</SP> which are fed from overhead line 1 running adjacent to telephone line 6, and the phase displacements are produced by including different amounts of inductance 16 in the different loads. In a modification, Fig. 3 (not shown), additional phase control is provided by a small variable condenser connected in parallel with the fixed condenser of a noise-reducing filter (comprising a resistor in series with a fixed condenser) which is connected across the secondary winding of supply transformer '13, as described in Specification 682,610. This filter may then be employed to reduce all the harmonics except those in a single narrow range of frequencies, the dephasing inductances 16 being adjusted to nullify those in the said single narrow range.

Title: Improvements in or relating to electrical alarm systems
IPC: E05B45/06
Filed: 1947-01-10
Abstract: 638,280. Burglar and like alarms. EISNER, H. Jan. 10, 1947, No. 946. [Class 118 (i)] In an electric burglar-alarm system, operated by forcing a door or the like, means are provided whereby the system is nullified when the latch of a lock is withdrawn in an authorised manner. On leaving a room or like enclosure by the door A the lock 1 is operated and closes contacts 17. Operation of setting switch 3 now completes the circuit for the setting relay 4 from the supply leads X and Y. This relay then holds via contacts 44 and 17. Contacts 43 close the circuit for the bulb 34 which glows to indicate that the alarm circuit has been set. Should the door now be opened in an unauthorised manner, contacts 25, 26 of the dooroperated switch 2 are bridged and, via contacts 47, complete the circuit of the indicator relay 5 which operates and holds by its contacts 52, the visual indicator 53 also being operated. Contacts 56 close the circuit of the alarm relay 6, which holds via contacts 61, and the alarm bell is rung by contacts 65. If, however, the door is opened by authorised withdrawal of lock 1, the contacts 17 are broken and the relay 4 releases, opening contacts 47 and thereby preventing operation of the alarm. An auxiliary alarm is provided for a second door B in which opening the door while the bolt 9 is closed completes the circuit for relay 5 and hence operates the alarm. A manual resetting switch 55 is provided to break the holding circuit of relay 5, and a similar switch may be provided to reset relay 6. A damage alarm circuit consisting of relay 7 in series with wires 71 is incorporated in the system. Relay 7 is normally operated, holding contacts 72, 73 open. , If the wires 71 are broken, the relay releases and contacts 72 complete the circuit for the visual indicator 74 while contacts 73 operate the alarm relay 6. This circuit may also act as a fire-alarm. The setting switch 3 may be located so that it is automatically operated when a person approaches the means of ingress, for example, a floor switch or photoelectric device. The modification of a pintumbler type lock to be incorporated in the system is also described.

Title: Thermal treatment cushion
Inventor: GAUDREAULT YVON
IPC: A61F7/10
Filed: 1997-04-03
Abstract: A flexible heat pad for heat transfer to a person's limb. The pad consists of a fabric (preferably cotton) envelope enclosing a load of cereal grains, preferably oats. Preferably, the water content of the oat is precisely monitored to remain within the 9 to 14% range by weight of the oat total weight. The quantity of oat grains inside the cotton envelope must be such as to provide even oat distribution within the cotton envelope enclosure, after deformation, whereby localized grainless pockets within the pad enclosure are substantially prevented. The pad is pre-heated for about two minutes inside a micro-wave oven, at full power setting, before use. Thermal inertia of the oat thereafter allows continuous heat diffusion to the limb for about half an hour. The pad may alternately be put into the freezer from at least four to six hours, to thereafter diffuse cold to the swollen limb part of a mammal.

Title: Resin part treated so as to be prevented from lowering bolt clamping load
Inventor: TANAKA YUJI
IPC: B29C71/02
Filed: 1988-01-06
Abstract: PURPOSE:To prevent the lowering of bolt clamping load, by a method wherein a resin part having a bolt clamping part is cooled within a temp. range from the use temp. of said resin part to temp. below heat deformention temp. while a strain is imparted to at least the seat surface part of the clamp bolt head of said part and holding said strain. CONSTITUTION:In a resin part having a bolt clamp part, the greater part of the lowering of bolt clamping load is generated by the lowering of the modulus of elasticity, that is, rigidity of a resin itself accompanied by the rising in the atmospheric temp. using the resin part and the effect of the shrinkage, that is, linear expansion of the resin accompanied by the falling of the atmospheric temp. as compared with the effect of the stress relaxation of the resin itself. From this, the resin part is cooled within a temp. range from the use temp. of the resin part to temp. below heat deformation temp. while a strain is imparted to at least the seat surface part of a clamp bolt head of the part and held to fix at least a part of a strain to the seat surface part of the clamp bolt head and, thereafter, said part is clamped by a bolt. The lowering of bolt clamping load is prevented by the stress generated corresponding to the release of the fixed strain with the rise in the temp. of the part thereafter.
