Inventor: BROKAW WILLIAM GOULD
IPC: B63C9/15
Filed: 1916-09-29
Abstract: 103,625. Brokaw, W. G. Sept. 29, 1916. Balls.-In means for inflating footballs, &c., comprising a frangible cartridge or container of compressed or liquified air or gas, the glass gas container a is enclosed in a sheath or casing c having packings g of rubber &c. to prevent shock, and the neck b of the container is enclosed by a sheath f of somewhat thick rubber attached to the nozzle c of the casing c, and by a cap n. The free end of the sheath f is fitted with a nozzle h having a screw-threaded orifice i, by which the cartridge may be attached to the valve nipple of the article to be inflated, the inflation being effected by breaking the neck b with the hand. To prevent ejection of the broken glass &c., the orifice i is made of smaller diameter than the neck b, and a perforated disk or wirecloth guard l may also be provided.

Title: Magnetic recording means
IPC: G11B5/60
Filed: 1970-03-23
Abstract: 1311967 Mounting magnetic heads BURROUGHS CORP 23 March 1970 [4 Aug 1969] 13898/70 Heading G5R [Also in Division F2] A flying head mounting includes a flat support 2 allowing restrained rotation about two perpendicular axes 44, 45 and being asymmetrical about the axis 44 which is transverse to the relative transducing direction so that the head assumes a positive angle of approach # to a record surface 10 when loaded by an actuator 16, 17 engaging the support at the intersection 46 of the axes 44, 45. The support includes a central platform 30 with bent-out headmounting tabs 31, 32 and coupled to gimbal frames 33, 36, 39 by opposed pairs of links such as 40, 41. The vertical links above axis 44 are longer than those below to produce asymmetrical deflection characteristics. The links of the various rings are generally of different widths or lengths to produce the asymmetry (Figs. 3-6, not shown).

Title: Improvements relating to centrifuges
IPC: B04B5/04
Filed: 1963-04-08
Abstract: 976,206. Centrifugal separators. G. N. HEIN. April 8, 1963 [May 7, 1962], No. 13930/63. Heading B2P. A centrifuge for separating liquid or liquid and solid mixtures, e.g. blood, comprises a rotor 28 having a chamber for holding the mixture to be separated, a plunger 30 rotating with the rotor for sealing off an outer part 112 of the chamber from an inner part 110, and a spring 34 which responds to a predetermined change in centrifugal force resulting from a change in the speed of rotation of the rotor for operating the plunger to seal the two parts of the chamber from each other. The chamber contains a disposable bag 26 held therein by a cap 40 of transparent material screwed on to the rotor. The bag, which may also be transparent, is made of organic plastic sheet material and consists of a flexible lower wall 164 bonded at its periphery to a more rigid upper wall 162, the walls defining an inner chamber 192 and an outer annular chamber 194 conforming in shape with the parts 110, 112 of the rotor chamber. In the position shown in Fig. 4, the plunger is depressed against the spring 34 and locked by a pair of spring-loaded latches 32 each having a head 116 engaging behind a lip 72 on the plunger. Maximum displacement. of the plunger relative to the rotor with cap 40 and bag 26 removed is limited by a screw 38. The rotor is detachably secured by means of a quickly releasable coupling 142, 144 on. a cone 134 which is a force fit on the end of a shaft 132 driven by an electric motor. At.the start of an operation the cap 40 is removed, the plunger depressed and locked as in Fig. 4 and a bag 26 inserted in and clamped in the rotor by the cap. A sample of blood is then introduced into the bag through openings 108, 174. The motor is energized to rotate the rotor so that the solids are separated and accumulate in the bag chamber 194 with a small quantity of plasma while pure plasma remains in the chamber 192. As the pressure exerted by the blood, as induced by centrifugal force, increases on the walls of the bag 26, the pressure is transmitted to the plunger 30 which, at a given value of centrifugal force, will move downwards against the force of the spring 34, whereupon the lip 72 on the plunger liberates the heads 116 of the latches 32 which under centrifugal force move outwards against their respective springs. The motor is de-energized resulting in a decrease in centrifugal force transmitted by the blood on to the plunger. The latter then moves upwards under the influence of the spring 34 acting on a spring cone 36 and raises the lower wall 164 of the bag 26 to seal it against the upper wall thereby sealing the chamber 194 from the chamber 192 as shown in Fig. 6. When the rotor stops, the pure plasma is removed for analysis by means of a syringe or pipette inserted through the openings 108, 174. The rotor may have a maximum diameter of 1¢ inches and may rotate up to 20,000 r.p.m. The volume of the blood sample is of the order of 2 mls.

Title: Improvements in or relating to continuously operable ovens
Inventor: HARRIS JOHN HEATON
IPC: G08B17/117
Filed: 1956-05-09
Abstract: When the atmosphere of a continuously operating oven approaches an explosive condition due to the presence therein of inflammable solvent vapours, which are evaporated from work passing through the oven, warning is given by means of an apparatus which withdraws from the oven a continuous stream of the atmosphere therein, and passes this continuous stream through a single chamber in which it is admixed with a gaseous fuel, supplied to the chamber at a constant rate and so predetermined as to form with said continuous stream an explosive mixture only when the solvent vapour content of the stream is of a predetermined value less than that necessary to render the oven atmosphere explosive, and causes the mixture while still in the chamber to move continuously past a source of ignition which is adapted so that when the solvent vapour content reaches or exceeds said predetermined value the ignition explodes the mixture.  The ignition means may be a flame extending into the chamber which initiates a signal operated by an electrical relay supported exteriorly of the chamber to control the on/off operation of a valve through which the gaseous fuel, e.g. coal gas, is admitted to the chamber and heat-responsive means located in the chamber and connected with the said relay to control energization and de-energization thereof.  The relay may also be connected to shut off the oven or to give an audible or visible indication of the danger, e.g. by means of a lamp or a bell.
