Title: Improvements in or relating to street lighting apparatus
IPC: F21V37/00
Filed: 1930-07-18
Abstract: 357,317. Supporting street lamps. MARSH, R. G., 19, Noel Road, Edgbaston, Birmingham. July 18, 1930, Nos. 21722 and 27721. [Class 75 (iii).] A street lamp a is carried by an arm b normally detachably suspended from a stretched cable g or other stationary overhead support and connected by a swivel joint c to a wall e, standard or the like so that it can be swung round in a substantially horizontal or inclined plane to bring the lamp to the side of the street for attention, by means of a controlling cable m, the arm being supported bv a tension cable h when detached from the cable g. The anchorage k for the cable h is located to one side of a vertical line passing through the joint c so that when the arm is detached from the cable g it will swing round automatically towards the side of the street. The arm b preferably rests normally in a bifurcated hook r at the lower end of a fitting f clamped to the cable g. A notch s is provided between the limbs of the hook r for engaging a pivoted tongue t on the arm to carry the latter clear of the hook when it is slightly raised and then lowered by means of the cable m. On the return movement, the arm rides up guides v and drops into place in the hook, the pulley u being pivoted on a pin u<1> so that the fitting is swung to bring the hook over to meet the arm. The arm may constitute a gas supply pipe, or a conduit for electric leads, for the lamp and may be braced with a steel wire l. A clock w for controlling the lighting and extinguishing of groups of burners in a gas lamp may be arranged directly above the lamp. When the cable g is stretched between tramway poles, the lamp is preferably mounted directly on the end of the arm, and the cables h, m are connected to the arm at points short of the tramway wires.

Title: Improvements in electrical heating devices and control arrangements therefor
IPC: H05B1/02
Filed: 1955-07-29
Abstract: 771,210. Supply systems for resistance heaters. GENERAL ELECTRIC CO. July 29, 1955 [July 30, 1954], No. 22021/55. Class 38 (4). [Also in Groups XI and XXXVII] An electric heating device, e.g. a pad 1, has a heating resistance 3 controlled by a thermostat 5 which may be heated by an auxiliary heater 9, and a half-wave rectifier 15 may be selectively inserted in the current supply to the heater 9, which is in series with at least a part of the resistance 3, so that the temperature of the device at which the thermostat becomes effective may be varied. The rectifier 15 may be connected in series or in parallel with the auxiliary heater 9 and may be mounted in an exterior switch 2, which may be operated so that the heater 9 supplies maximum heat to the thermostat to obtain a low temperature setting of the device, or so that the rectifier is connected in circuit with the heater 9 to give an intermediate temperature setting, or so that the heater 9 and the rectifier are disconnected to provide a high temperature setting of the device. A wire 7 of the supply plug 4 is connected through a safety thermostat 6 and the control thermostat 5 to one end of the main heating resistance 3. The other wire 8 of the plug is connected to an elongated conducting bar 17 in the switch 2, which has a second conducting bar 18 connected to the other and 18 of the element 3. The switch has a slider 20 moving transversely to the bars 17, 18 from the off position shown first to the " low position," in which it engages a contact 11 connected by a line 10 to one end of the auxiliary heater 9, next to the " medium " position in which it engages a contact 16 to include the rectifier 15 in the supply to the heater 9 and lastly to the " high position," when the heater 9 and rectifier are disconnected. The other end of the heater 9 is connected by a line 12 to an intermediate point 13 of the element 3 or to one end of the element 3, e.g. at 14. A capacitor may be arranged in parallel with the half-wave rectifier to increase the energy supplied to the heater 9 in the medium position.

Title: Improvements in grab dredgers
IPC: B66C3/12
Filed: 1919-09-08
Abstract: 153,722. Price, J. Sept. 8, 1919. Grab-buckets.-In a double-chain grab-bucket, the opening arms C, D are secured to the outside of the jaws A, B and the suspension links I, J are disposed between them. The arm C is connected to the jaw A by a strap C<1> disposed so that the arm D can pass between the arm C and the bucket A. The closing and lifting rope M which passes round sheaves G, H on the head E and sheaves on the arms C, D is passed over a sheave and under the reduced central part of a drum P, both on the jib of the crane, and is then led to the winch round a sheave carried by a weighted arm W pivoted to the jib. The opening ropes N, N pass from the head E to sheaves on the head of the jib and are led thence to the drum P, which is free on the shaft P<1>, but during lowering is connected to it by ratchet gear R. The speed of lowering is controlled by a brake 0 which is applied continuously by a weighted lever V unless the lever is raised by pulling the rope Y. The central part of the drum P is covered with friction material and during lifting is rotated by the rope M, thus taking up the slack of the ropes N. The grab is discharged by throwing the winding-drum for the rope M out of gear, and this also causes the fall of the arm W to the position shown in dotted lines, Fig. 5. The brake 0 is then taken off, to allow the grab to descend, and is kept off until the lifting again commences. When the grab has penetrated the material to be raised, the winding-drum for the rope M is put into gear, but as the strain on the rope M is light until the grab is closed, the rope M remains clear of the drum P until lifting commences. The arm W is then raised, and the opening ropes N are wound on to the drum P.

Title: Improvements relating to waste heat boiler arrangements
IPC: F22B1/18
Filed: 1962-06-08
Abstract: 1,005,590. Heating steam boilers by waste gases; converter chimneys. WAAGNERBIRO. June 8, 1962 [June 9, 1961], No. 22348/62. Headings F4A and F4J. The hot combustible waste gases emitted by intermittently working metallurgical furnaces such as steel-making converters 2 pass without admixture with air into water-cooled conduits 4 in which part of the sensible heat of the gases is removed and then are introduced together with combustion air into a radiation chamber 11 of a waste heat boiler 6 which is also equipped with auxiliary firing means 10 serving to compensate for the fluctuating heat output from the converter waste gases. The water jacket 34 of the conduits 4 form a shunt circuit for the boiler in which water from the base of a reservoir 37 is circulated and heated water drawn off as feedwater from the upper level in the reservoir which may also serve as a de-aerator. Alternatively heat from the circulated water may be given up to the feedwater in a heat exchanger. The radiation chamber contains steam generating tubes 22 and has an upper inclined wall below a vertical gas pass containing a superheater 13 and economizer sections 14 with steam and water drum 20 disposed externally. The gases may either pass to a regenerative air preheater 15 or, as is the ease when operating with dust-laden converter gases, to a stack 17. The supply of fuel to the auxiliary firing means is controlled by the valve 28 in inverse relation to the heat output from the waste gases and the proportions of combustion air are similarly controlled. In a modification (Fig. 9, not shown) part of the conduit 4 is cooled by air subsequently used as combustion air. The boiler itself may alternatively be constructed as a forced throughflow or forced circulation boiler.

Title: Improvements in boot protectors
IPC: A43C13/02
Filed: 1919-09-11
Abstract: 159,912. Lulham, T. R. Sept. 11, 1919. Protectors, securing; studs, detachably app l i e d. - Detachable rubber &c. pads are secured to shoe soles and heels by separable metal plates engaging screws fixed in the shoes. When a pad becomes worn, the screws are slightly loosened and the pad is turned round and re-affixed with the same plate or a somewhat similar plate and pad are taken from the other shoe and entirely fresh screw holes are made so as to avoid loose or insecure screws. A toe pad a, Fig. 26, is secured by a separable metal plate f<1> which may be made in two parts and provided with keyhole slots g to engage screws h. When the pad is worn the screws are slightly loosened and the plates rotated so as to be free of the screws to enable the pad to be replaced after being turned through 180‹ the screws are then tightened up again. After being worn in the new position the pad and plates can be transferred to the other shoe and the screw holes in the plates are so arranged that fresh screw holes are necessary in the shoe soles. The metal plates for each shoe are similar but the slots are reversed. Various modifications of pads and plates consist in placing the slots the same way so that a plate can be removed by sliding, or in opposite directions at right-angles to the length of the plate so that a slight rotation is necessary. Sometimes a pad is retained by two plates in line as the middle pads in Fig. 26. The pads are slotted or provided with two holes in place of one slot to accommodate the screws. The pads are undercut as at c, Fig. 22, and a. filler c‹, Fig. 23, is used. The filler is wider at the top than the slot c so that the outside edges of the pad tend to turn down to the shoe sole.

Title: Improved process for the manufacture of ª‰-naphthoquinaldine
Inventor: RILEY ALBERT
IPC: C07D221/10
Filed: 1955-08-15
Abstract: b -Naphthoquinaldine is manufactured by a process which comprises heating 2-naphthylamine-1-sulphonic acid or a salt thereof with sulphuric acid, crotonaldehyde and an oxidizing agent comprising nitrobenzene, sulphonic acids of nitrobenzene or arsenic acid. Substances assisting oxidation, such as vanadium pentoxide and selenic oxide, may be added to the reaction mixture. The product may be isolated by cooling the reaction mixture, preferably after diluting with water when the b -quinaldine crystallizes, probably as the acid sulphate; it may then be filtered off, redissolved in hot water to give an acidic solution and precipitated by the addition of a base, for example, sodium hydroxide.  It is preferred to treat the acidic solution with a nitrite to decompose any trace of unreacted b -naphthylamine which may be present.  In the example, 2-naphthylamine-1-sulphonic acid is heated with sulphuric acid; nitrobenzene-m-sulphonic acid, ammonium vanadate and crotonaldehyde are added and b -naphthoquinaldine is separated from the resulting mixture.
