Title: Improvements relating to slip boxes or starting devices for dog racing
IPC: A63K3/02
Filed: 1928-02-07
Abstract: 308,036. McKee, J. A., and Scott, J. S. Feb. 7, 1928. Dog-racing apparatus.-Dog races are. handicapped by dividing the slip boxes into units for one or more dogs and spacing them along the track, all'the doors being released simultaneously by means of solenoids. Figs. 1 and 2 show a box for a single dog, mounted on wheels 5 and with handles 4. The door 2 moves upwards about its upper end 2<c> under the influence of a spring 6 but is normally held at its lower end by a catch 8<a> on a rod 8 pivoted at 8<b> to the core 9<a> of a solenoid 9. When the solenoids 9 are energized simultaneously the catches 8<a> are withdrawn and the doors move upwards, their central bars 2<d> being gripped each by a catch 7. In a modification, Figs. 4, 5 and 7, an extra internal catch arrangement 12 prevents release of the door from the outside other than by energizing the solenoid 9. A rod 14 is pivoted at one end 14<a> to a bracket 17 and at the other end 16 to a rod 15 which is pivoted to the catch rod 8 and is under the infiuence of a spring 17<a>. The ends of the rods 14, 15 which are pivated together are normally held down by a catch 12 pressed by a spring 13, Fig. 5. When the solenoid 9 is energized the core 9<a> rises and rocks the catch 12 counterclockwise so that the rods 14, 15 assume the position of Fig. 7 owing to the spring 17<a>, thereby moving the rod 8 to release the door catch.

Title: Improvements relating to method of and apparatus for measuring the surface areas of porous materials
IPC: G01N15/08
Filed: 1952-02-13
Abstract: 717,966. Measuring surface area of porous material. AMERICAN CYANAMID CO. Feb. 13, 1952 [April 26, 1951], No. 3810/52. Class 106 (2) [Also in Group XXIX] A method of measuring the surface area of porous material such as catalysts and pigments having surface areas greater than 0.5 square meters per gram, comprises introducing a gas at a constant rate of flow into an evacuated system containing a weighed amount of the material cooled to approximately the boiling point of the gas introduced, measuring the time required for the gas in the system to reach a pressure having a value relative to a saturation pressure of between 0.1 and 0.3 and preferably 0.2, and' calculating from the time required the surface area of said material. As illustrated,. Fig. 1, from 2 to 20 grams of dry catalyst sample is weighed into a tube 1. The sample is then degassed by opening the valves 3, 4 and 5, and closing valve 7 to evacuate the tube 1 at room temperature until a pressure of less than 0.5 mm, or a leak rate of less than 0.005 cc (standard temperature and pressure) per minute is obtained. The valves 3, 4, 5 and 7 may be needle type valves. When the tube 1 has been evacuated, valve 3 is closed to isolate the sample from the system and the tube is immersed in a bath of liquid nitrogen 6. Valve 7 is then opened and nitrogen from cylinder 8 flows through a pressure controller 17 into the vacuum pump (not shown) until steady conditions prevail as indicated by a steady reading on a gauge 21. Valve 4 is then closed and a timer 10 simultaneously started. The rate of flow of nitrogen is then checked by noting the room temperature and the time in seconds required for the vacuum to decrease from 29 inches to 24 inches gauge pressure on gauge 20. These values are then substituted in the following equation to obtain the flow rate y in cc per minute: wherein : #P=change of pressure (29 inches-24 inches) T=temperature in degrees absolute t=time in minutes for pressure change # P V 1  = volume in cc of low pressure side of system between valves 17, 3 and 4. Valve 4 is now re-opened and the nitrogen is evacuated until steady conditions again prevail. The surface area of the sample is measured by closing valve 4 and immediately opening valve 3, the timer 10 being started when valve 4 is closed and electrical contacts on a pressure gauge 20 connected to the tube 1 are so set that the timer is stopped when a pressure having a value relative to saturation pressure of 0.2 is reached. From the time in minutes that is required to reach the aforesaid pressure, the volume of nitrogen absorbed under standard conditions may be calculated from the expression: The figure 3.5 is a constant evolved from an empirical observation.

Title: Improvements relating to the production of highly concentrated nitric acid
IPC: C01B21/26
Filed: 1941-03-20
Abstract: 547,959. Nitric acid. BAMAG, Ltd., and MANNING, A. H. March 20, 1941, No. 3831. [Class 1 (ii)] Concentrated nitric acid is produced by 'oxidation of a solution or admixture of nitrogen tetroxide in nitric acid of medium concentration by means of oxygen in excess passed, in counter flow to the mixture, through a long reaction tube, the excess oxygen being led to the lower part of a pressure feed vessel above the tube so that the oxygen bubbles through an acid mixture in the feed vessel to effect partial oxidation of nitrogen oxide and to raise pressure therein to promote the flow of the mixture into the reaction tube. The process is carried out cyclically in an apparatus comprising a reaction tube 14, a storage vessel 1 for a mixture of nitric acid and nitrogen tetroxide, a pump 2 and constant level tank 4, and a number, e.g. 3, of pressure feed vessels 36-38. Oxygen is passed into the tube 14 from a tube 30 and the unabsorbed excess is allowed to flow, for example into the middle feed vessel 37, through a dip pipe 17, some being absorbed and the remainder causing a rise of pressure whereby the liquid in the feed vessel flows by gravity through a valve 1'2 into the reaction tube. After most of the liquid in vessel 37 has passed into the reaction tube a valve 20 is opened and liquid in the vessel 38 passes into the reaction tube. The valves 12, 19 are then closed and the oxygen remaining in vessel 37 is allowed to pass into vessel 36 through a tube 17. When the pressure in vessels 36, 37 is equalized connection between them is broken, the vessel 37 vented to atmosphere through a valve 29 and liquid from tank 4 allowed to flow into it. The operation is then continued seriatim.

Title: Improvements in or relating to sorting machines for record cards
Filed: 1946-02-14
Abstract: 608,082. Statistical apparatus. COMPAGNIE DES MACHINES BULL. Feb. 14, 1946, No. 4729. Convention date, Aug. 20, 1942. [Class 106 (i)] A record card sorting machine comprises a card analysing device which co-operates with a series of electromagnets so that when a selected magnet is energized it positions an associated cam lever in the path of one of a plurality of catches moving on an endless band. The catch is displaced into a position in which it controls mechanically the entry of a corresponding record card into a receptacle corresponding to the record analysed. The invention is described as applied to the sorting machine described in Specification 343,890. Cards are fed from a magazine 22, Fig. 3, between rollers 34, 37, past a single sensing brush 202 adjustable to any particular card column, and between further rollers 35, 36 ... until the feed is taken over by beams 62a, b, c on an endless chain 56. Each beam 62 carries a row of catches 63 having hooked ends, one of which is engaged in the beam and forms a journal about which the catch can be turned to set it into two positions, a spring plate 65, Fig. 8, being shaped to receive the catches in either position. The catches are controlled by a series of levers 138, Fig. 3, having cam portions 189, Fig. 8, staggered along the line of travel of the card and corresponding, respectively, with the values of the hole positions in each card column. The sensing of a hole in a card by the brush 202 causes energization of a corresponding magnet and the rocking of an associated armature pulls a rod 167, Fig. 9, and rocks a pawl 162 out of the path of its spring-urged lever 138, which is pulled downwards so that its cam portion 189, Fig. 8, is brought into the path of the corresponding catch 63 on the next beam 62, which catch is thereby pushed across into its operative position. As this beam 62, pushing the card along, reaches the card pocket appropriate to the hole sensed, the positioned catch 63, Fig. 6, engages and rocks a lever 76 which, in turn, rocks a second lever 81 which releases a spring-urged pocket flap 84 to allow the card to be guided into that pocket. The flap 84 is restored to its lower (normal) position by a lever 86, linked to the pocket flap, which is rocked clockwise by a cam 96 on a shaft 92 common to all the pockets. A cam-shaft 121, Fig. 3, causes a row of small levers 105 to be rocked in succession, each engaging the nose 150 of its corresponding cam lever 138; by this means the released lever 138 is restored and re-latched. The displaced catch 63 is restored by a stationary comb.
