Title: Hypodermic ampoules
IPC: A61M5/28
Filed: 1962-09-18
Abstract: 1,011,301. Capsules. H. DUNMIRE. Sept. 18, 1962 [Sept. 18, 1961 (2)], No. 35529/62. Heading B8C. [Also in Division A5] A capsule comprises a collapsible cup-shaped body 10 having an upper end wall, a circumferential side wall, a closure 14 and a hypodermic needle 15 mounted in the upper end wall so that it is enclosed in the body and punctures the closure when the body is collapsed, the body having a primary hinge portion 23 at which circumferential bending is initiated upon movement of the upper end wall towards the closure to collapse the body and invert the upper portion of the body within the lower portion. The closure disc 14 is heatsealed to the cup 10 and the point of the needle is located in a passage 102 in a gland 20 in the centre of the closure. The side portions of the cup comprise a lower rigid side wall 22 joined to an upper more flexible side wall 21 by a thinner peripheral portion 23 which defines the primary hinge. A peripheral notch 24 between the end wall of the cup and the upper side wall provides a secondary hinge about which the upper side wall folds as the body is collapsed. The secondary hinge prevents the cup returning to its uncollapsed condition. During assembly, a metal element e.g. a ring 138, powder or printed metal, is disposed between the cup and the closure which have abutting flanges held together between non-conductive dies 134, 139 (Fig. 12). The metal element is heated inductively so that adjacent portions of the cup and closure become heated to seal them together. Alternatively, a dielectric element placed between the flanges is heated dielectrically to seal the cup to the closure.

Title: New diamines and intermediates therefor and a method for their preparation
IPC: C08G69/32
Filed: 1963-09-09
Abstract: The invention relates to compounds of the formula <FORM:0979407/C1/1> in which R is hydrogen an alkyl group of up to 3 carbon atoms or a phenyl group, and X and Y are aromatic radicals.  The aromatic radicals may be single, multiple or fused-ring radicals, as in phenylene, biphenylene or naphtylene, and may be substituted by halogen atoms or alkyl, alkoxy or nitro groups.  If the aromatic radicals are multiple radicals, they may be joined directly or through a sulphonyl or methylene (or substituted methylene) group or through a group -NH- or through an oxygen or sulphur atom. The compounds may be prepared by condensing two mols. of a nitroaromatic acid or an ester or halide thereof with one mol. of an aromatic diamine, and reducing the dinitro compound of the formula <FORM:0979407/C1/2> so obtained.  The condensation of the nitroaromatic acid or its derivative with the diamine may be effected by the Schotten-Baumann reaction or in homogeneous solution, a number of solvents being specified.  The reduction of the dinitro compound may be effected catalytically or chemically, e.g. with iron and sulphuric acid, stannous chloride and hydrochloric acid or a polysulphide solution.  Both the amino compounds and the nitro compounds of the formulae given above are claimed per se. Examples are given in which (1) m-nitrobenzoyl chloride is condensed with m-phenylene diamine to yield N,N1 - m - phenylene - bis (m - nitrobenzamide), which is reduced to yield N,N1-m-phenylene-bis (m-aminobenzamide), (2) p-nitrobenzoyl chloride and m-phenylene diamine similarly yield, in turn, N,N1-m-phenylene-bis (p-nitrobenzamide) and N,N1-m-phenylene-bis (p-aminobenzamide), (3) m-nitrobenzoyl chloride and p-phenylene diamine similarly yield, in turn, N,N1-p-phenylene-bis (m-nitrobenzamide) and N,N1-p-phenylene-bis (m-aminobenzamide), (4) m-nitrobenzoyl chloride and 2, 7-naphthylene diamine similarly yield, in turn, N,N1-2, 7-naphthylene-bis (m-nitrobenzamide) and N,N1-2, 7-naphthylene-bis (m-aminobenzamide), (5) products corresponding to those of Example 4 are obtained from m-nitrobenzoyl chloride and 1, 5-naphthylene diamine, (6) products are prepared similarly from benzidine and durene diamine and m-nitrobenzoyl chloride. Reference is made also to the following products: N,N1-m-phenylene-bis-(31-aminobiphenyl-3-carbonamide) N, N1-p-phenylene-bis-(31-aminobiphenyl-3-carbonamide), N, N1-(2, 7-naphthylene) - bis - (7 - amino - 2 - naphthamide), N, N1 - tetramethyl - p - phenylene - bis (41 - aminobiphenyl-4-carbonamide), N, N1- (1, 7-naphthylene) - bis-(m - aminobenzamide), N, N1-(1, 7-naphthylene)-bis - (31- aminobiphenyl - 3 - carbonamide) and N, N1- (1, 7-naphthylene) - bis (7 - amino - 2 -naphthamide) The amino compounds are useful in the manufacture of polyamides.

Title: Battery voltage regulating systems
IPC: H02J7/32
Filed: 1969-07-16
Abstract: 1279010 Automatic voltage control NIPPON DENSO K K 16 July 1969 [26 Sept 1968] 35876/69 Heading G3R The voltage of a battery 1 charged by a variable speed alternator 2 through a rectifier 5 is controlled by a voltage regulator 6 which includes a transistor 9 for switching on and off the field winding 3 of the alternator and which is supplied therefrom through rectifiers 19, 20 so that it receives a periodically interrupted energizing voltage, Fig. 6 (not shown), the mode of operation being such that regulation occurs around a voltage V3 bounded by lower and upper limits V1, V2 to form a voltage range which prevents operation of the regulator 6 by the pulsating components present in the output of the rectifier 5. When a period of interruption of the energizing voltage to regulator 6 comes to an end, the transistor 9 is turned on or off according to whether the battery voltage V B  is less or greater than V3 and remains in this condition for the period of energization unless V B  moves outside the range V1-V2. For example if V B  is less than V3 transistor 9 is turned on and will only be turned off if V B  exceeds V2 during the energizing period. The range V1- V2 is chosen to exceed the peak to peak value of the high frequency pulsating component in the output of the rectifier 5. The Specification discusses the derivation of equations for V1, V2 and V3 using the values of the resistors 10, 11, 14, 15, 16, the forward resistance of the diode 4 and the breakdown voltage of the Zener diode 12. A comparison is made with a known voltage regulator, Fig.1 (not shown) which employs a capacitor to prevent operation of the regulator by the pulsating components. Further embodiments of the invention, Figs.3 and 4 (not shown) respectively add an ammeter and a resistor or a lamp, a resistor and an inductance to the circuit of Fig.2

[Class 53] [See also Group XVII] Apparatus for filling a battery casing or other container 2 with liquid through an opening in the side of the container comprises a liquid container 8 which after being emptied is filled to a predetermined level from an inverted bottle 10. The container 8 is connected by a flexible tube 12 to a trough 13 secured to a bracket 14 which is removably supported in the front plate 15 of the apparatus. The bracket 14 carries a rubber pad 16 which fits round the filling opening of the vessel 2 which is pressed against the pad 16 and released therefrom by a cam 17 which can be rotated by a handle 20. A spring plate 21 is interposed between the cam and the vessel 2. When the cam is rotated to clamp the vessel 2 in position it also rotates two arms 28 which raise the container 8 and bottle 10 which are supported on a member 22 slidable on rods 24. Liquid in the container 8 then flows under gravity into the trough 13 and vessel 2. A modification is described in which the trough 13 and pad 16 are duplicated for filling a battery comprising two cells having separate filling openings.

Abstract: A cement having a rapid initial set, e.g. within 12 seconds, and a sufficiently slow hardening speed to avoid the formation of cracks by the evolved heat, comprises a mixture of aluminous cement and Portland cement or other calcium silicate cement free from gypsum or other retarding agent.  The cement may be made by mixing the two kinds of clinkers, e.g. in pro portion from 1 to 3 to 3 to 1, and grinding.  The cement is specially intended for the repair of walls and masonry through which water is seeping, the cement being applied by a cement gun to the moist surface of the structure remote from the water pressure.  It may also be utilized in building construction, layers of the cement being applied by a gun or otherwise.  Reference has been directed by the Comptroller to Specifications 18345/08, [Class 70], and 231,867, [Class 22].
