Title: Improvements in apparatus for teaching arithmetic
IPC: G09B19/02
Filed: 1943-07-24
Abstract: 558,483. Educational appliances. DUTTON, A. B. July 24, 1943, No. 12094. [Class 146 (ii)] Apparatus for teaching arithmetic or colours consists of a set of 10 coloured cards B and 10 small boxes each containing 20 coloured cubes A pierced for threading on a cord. Each card is coloured in bands of varying width in multiples of half-inch, and the cubes are also half-inch in colours to match the bands. Each cord C is fastened at one end to a card and has a tag D at the other end for threading the cubes, being passed through a notch F in the cord to secure it in place. When threaded, the cubes have to be rotated to match the colour underneath.

Title: Improvements in or relating to record-card-controlled statistical machines
Filed: 1929-04-18
Abstract: 311,321. British Tabulating Machine Co., Ltd., (Assignees of Hayes, C. L.). May 9, 1928, [Convention date]. Statistical apparatus.-In a record-card controlled machine having card reading elements arranged to co-operate with cards punched to represent negative quantities and with a special perforation in one of the " 9 " hole positions to distinguish the negative from positive quantities, the negative quantity is represented by the complement of the number with respect to nine and means are provided for entering an additional unit in the units wheel of the accumulator by an impulse brought about by the reading of the said " 9 " hole. The motor control and counter control circuits are arranged in the usual manner as shown in Fig. 5, a card in passing between the brushes 2 and common contact 3 engages a lever 4 to close contacts 5 and a cam 6 closes contacts 7 to energize a motor control relay magnet 9 and a counter control relay magnet 10. The items are entered into the accumulator under control of the operating magnets 1 by means such as described in Specification 131,277. Each accumulator is contained in a casing 15, Figs. 1 and 2, and as shown has eight magnets 1 and nine numeral wheels 16. The armature 18 of each of the magnets is mounted on a pivoted rod 17 and co-operates with a clutch lever 20 pivoted at 23 and extended to engage a groove in the usual sliding clutch members 26 which are mounted on a shaft 27 driven by means of gear wheels 28, 29 from the shaft 30 and cooperate with similar members 31 geared to the numeral wheels. In performing subtraction the complement of the number to be subtracted is added on the numeral wheels 16a-16g. By means of plug connections 41 the brushes 2 are associated with magnets 1a-1g and a plug connection 42 from a special wheel 16s is made to the brush 2 of one of the higher denominations receiving an entry of nine as the complement. The ratio of the gearing between the clutch member 31 and this special wheel is such that the wheel rotates a complete revolution during nine-tenths of a revolution of the shaft 27. During the last part of the rotation of the wheel 16s a tooth 43, Figs. 5 and 6, of a ratchet wheel 44 thereon engages a cam surface on a pawl 45 which rocks on its pivot and through a pin 46 releases a latch member 47 from, engagement with a lug on a spring-controlled arm 49 carrying a pawl 50 co-operating with the wheel 16<a> of the units denomination. The arm 49 is arrested by a common operating bar 52 which in the usual manner restores the arm 49 and causes the pawl 50 to advance the units wheel one step. The true complement is obtained even if the units or other lower denominations do not comprise significant figures by reason of the successive transfers effected by the addition of unity to the wheel 16a.

Abstract: 674,464. Percussive drills. ATELIERS DECONSTRUCTIONS MECANIQUES ARMAND COLINET. May 19, 1950, No. 12639/50. Class 124. A pneumatic hammer having a jet of atomised water to lay dust during working has a nozzle removably fixed to the tool holder by a clip, and a key engaging the holder and the flattened end of the nozzle, axial movement of the clip and the escape of the key being prevented. As shown, water is supplied from a hose 32 to a chamber 34 in a valve housing containing two valves 5, 5' joined by a stem 35 and urged on to their seats by a spring 33. Compressed air entering the tool handle 1 through a passage 2 acts on a diaphragm 4 to open the valve 5' and allow water to enter a tube 9; at the same time a supply of compressed air enters the tube 9 through a passage 8. The forward end 10 (Fig. 16) of the tube 9 is flattened and is held in a clip 11 surrounding the nose 13 of the tool by a cotter pin 15 which is prevented from falling out by a pin 18. The tube may be released by driving the pin 18 into a depression in the clip. A groove 17 in the nose of the tool co-operates with the cotter-pin to prevent axial movement of the clip. The amount of air admitted with the water may be controlled or entirely shut off by a plug entering the passage 8, Fig. 2 (not shown). Disconnection of the hose 32 allows the tool to work dry.

The sulphuric acid has a concentration of 15 to 43 wt. per cent and is used in an amount of 8-40% based on the THF. The amount of perchloric acid is 0À05 to 20 wt.per cent based on the fuming sulphuric acid and may be 100% perchloric acid or its hydrate (60-70% acid). Temperatures of - 40 to 80 C. may be employed and the reaction system may be closed or open and with or without a solvent. Polymerization is terminated by addition of water and the mixture is heated to remove monomer and to hydrolyse the sulphuric acid ester radicals at the ends of the polymer. On standing at room temperature, an upper oily layer of the OH- terminated polymer separates and is neutralized, dehydrated and desalted to give colourless liquid or waxy polymers which can be converted to polyurethanes.
