Title: Improvements in Apparatus for Testing the Condition of the Respiratory Organs and Measuring the Quantity of Expired Air.
Inventor: BROWN HAYDN
IPC: A61B5/095
Filed: 1916-02-26
Abstract: 104,365. Brown, H. Feb. 26, 1916. Spirometers. - The clock-work indicating- mechanism in spirometers of the kind described in Specification 3716/13 is replaced by mechanism which depends for its operation on the gradual sinking of a body in a liquid during the period of exhalation. Fig. 2 shows one form of apparatus in which inner and outer cylinders c, a and an exhalation tube bare arranged as described in the above-mentioned Specification. A rod c<3> depending from the cylinder c is curved inwardly at the upper end and co-operates with a wire loop on the outer cylinder so as to tilt the inner cylinder when it occupies its lowest position. In the tilted position, the wire d hears against and locks the scale rod e and its attached piston f. As long as the cylinder c is raised by the exhalation, the rod e is unlocked and sinks gradually as the liquid passes the piston; but at the completion of the exhalation, the rod is relocked by the cylinder. The reading on the scale opposite the wire d is a measure of the quantity of air exhaled. A wire g limits the upward movement of the cylinder, and guide-rods a<2> for the cylinder c are fixed to the outer cylinder. In a modified construction, the upper part of the rod c may be bent back upon itself and caused to move over a scale on the outerwall of the cylinder a. In some cases, the rod e may be omitted and the piston attached by a cord to mechanism which actuates a pointer moving over a scale.

Title: Improvements in or relating to the production of alumina gel-containing catalysts of high surface activity
IPC: B01J23/16
Filed: 1951-02-07
Abstract: An alumina gel-containing catalyst of high surface activity is prepared by precipitating aluminium hydroxide from an alkali metal aluminate solution by reacting it with a mineral acid, filtering and washing the aluminium hydroxide to produce a filter cake containing 10-20 per cent by weight of solids, mixing the cake with a quantity of a water-soluble organic acid within the range of 0.5-2 mols for each mol of alumina in the filter cake, incorporating one or more oxides of polyvalent metals of the fifth or sixth groups of the periodic system into the peptized paste and calcining the product, the amount of the oxide constituting 2-30 per cent by weight of the finished catalyst.  Specified metal oxides are those of chromium, molybdenum, tungsten and vanadium and the oxide may initially be incorporated as a salt, e.g., ammonium molybdate.  Specified organic acids are formic, acetic, glycollic, oxalic, maleic and tartaric acids.  The catalyst is preferably calcined at, for example, 1050-1100 DEG F, ground, screened, mixed with water and graphite, pelleted and calcined again at, for example, 1100-1200 DEG F.

Title: Lever operated electrical switch
IPC: G05G9/047
Filed: 1962-01-26
Abstract: 967,204. Switches held set and freed mechanically; retractive switches. TELEMECANIQUE ELECTRIQUE. Jan. 26, 1962 [Jan. 30, 1961], No. 3108/62. Heading H2B. A switch comprises a lever 8, mounted by a swivel joint 13, 14 and arranged to move from a central off position to any one of four micro-switch 20 operating positions. The four positions are defined by four perpendicular cam tracks 5 engaging a ball 6 carried by a tube 7 sliding on the lever 8 against spring loading 9. The cam tracks 5 are formed in independent, changeable .sectors 1 each mounted by a lug 3 engaging an aperture 4 in a cup member 2. The cup 2 also holds in place four actuating springs 22 which transmit movements of a bush 11 on the tube 7 to switch buttons 21 with some lost motion. The switch buttons may be arranged for displacement parallel to the direction of cam tracks 5 in which case only a single switch is operated in each position of the lever 8. Alternatively the sectors 1 may be displaced through 45 degrees (holes 4 being provided at 45 degree intervals) so that two adjacent switches are operated together. In the embodiment of Fig. 1, the lever 8 returns to the central position when released. In a modification using the sector shown in Fig. 4, the lever will remain set. One or more positions of the lever may be blocked off using the sector of Fig. 5. In another modification the cam tracks allow the lever to move between positions without returning to the central position.

Title: Machines for inseting insulating wedges into slots of a magnetic core
IPC: H02K15/10
Filed: 1975-01-24
Abstract: 1447197 Placing slot insulators in magnetic cores INDUSTRA PRODUCTS Inc 24 Jan 1975 [28 Feb 1974] 3210/75 Heading B3A A machine for placing insulating wedges into slots of a magnetic core by linearly moving wedge push rods 29 into a wedge containing magazine to force wedges axially from the magazine into the core slots includes, for inserting wedges of varying length, means for reciprocating the push rods in the direction of wedge insertion and variable length coupling means interconnecting the push rods with the reciprocating means to vary the distance that certain push rods force corresponding wedges to allow for wedges of varying lengths. The push rods 29 are mounted on a carriage 25 which is reciprocated by rotation of threaded rods 27 and the rods force individual wedges between guides 31 into the stator slots. The carriage also forces a stripper through fingers 11 in which are located wound coils. The distance the rods 29 are moved is varied by means of air cylinders 33, 33a and depends upon the length of the wedges to be inserted. The cylinders move an upstanding pin 35, which is located in a slot 45 in a plate 47, so as to rotate the plate. Pins 51, 53 on the plate locate in slots in plates 55, 59 in certain locations of the plate 47. In one limiting position of the plate 47, four pins 51 bear on the plate 59 and four pins 53 bear on the plate 55 and all push rods, e.g. exemplary rods 57, 61, will move the full travel of the carriage 25. In an intermediate position of the plate 47, the pins 51 are in alignment with slots in the plate 59 and as pins 53 raise the plate 55 the plate 59 will not move until the carriage contacts it and hence the rods 57 will travel a shorter distance than the rods 61. In the other limiting position of the plate 47 the pins 53 enter holes in the plate 55, so that both plates 55, 59 and their associated push rods travel a shorter distance.

Title: Keying means for producing pulses of electrical energy of variable duration
IPC: H03K7/10
Filed: 1945-02-08
Abstract: 600,742. Pulse modulation. MARCONI'S WIRELESS TELEGRAPH CO.. Ltd. Feb. 8, 1945, No. 3250. Convention date, June 30, 1943. [Class 40 (v)] To produce a train of square pulses modulated in width, or width and recurrence frequency, means are provided for comparing the phases of an unmodulated or frequency-modulated sine wave and a phase-modulated derivative thereof, the duration of the pulses varying between half a period for phase agreement and zero for phase opposition. In one embodiment the double triode 6, Fig. 1, has an unmodulated wave from source 1 applied to grid 12 and a phase-modulated derivative produced from modulator 3 applied to grid 10 as shown in Fig. 3. Current passes in the common cathode resistance 8, at all times except when both grids are negative, to bias a further triode 14 to cut-off and allows condenser 22 to charge. Square pulses are produced during intervals when valve 14 becomes conducting to discharge condenser 22, as shown in Fig. 4. The diode 20 across the output load resistance 21 is non- conducting during these intervals. In a further embodiment, a frequency-modulated wave from the tuned primary of transformer 24, Fig. 2, is applied to grid 12 and a phase-modulated derivative of the frequency-modulated wave from the tuned secondary of 24 is applied to grid 10 as shown in Fig. 5. The valve 14 is provided with a variable grid bias from potentiometer 28 connected across a source of D.C. voltage. There are two modes of operation depending on the polarity of the connection of the secondary of transformer 24 to grid 10. In one mode, Figs. 5 and 6, the smaller the pulse recurrence frequency the greater the pulse width, and, in the other, the greater the pulse recurrence frequency the greater the pulse width. A particular case of the first mode which can be selected is that in which the average pulse energy remains constant to provide a measure of secrecy in signal transmission.
