Title: High firing rate hypervelocity gun
Inventor: DARDICK DAVID
IPC: F41A1/02
Filed: 1968-09-03
Abstract: 1,248,783. Hypervelocity guns; cartridges and boosters. TRW Inc. 3 Sept., 1968 [1 Sept., 1967], No. 41910/68. Headings F3A and F3C. A hypervelocity gun for firing primary ammunition rounds 32 containing a primary propellant 38 and a projectile 34 and booster ammunition rounds 42 containing a booster propellant 44 comprises a barrel 12 having a bore 14 and breech means 16, 18 for transporting primary ammunition rounds in succession to a primary firing position at the breech end of the barrel and co-axial with the bore thereof and booster ammunition rounds in succession to at least one secondary firing position in which the booster propellant in each booster round is in ignition relation to the bore forward of the breech end of the barrel. The arrangement is such that when a primary round is fired the projectile thereof is propelled forwardly through the bore and the propellant gases from the primary round ignite a booster round in the or each secondary firing position after the projectile has passed the or each position to produce additional propellant gas which enters the bore behind the projectile to further urge it through the bore. In the construction shown the breech means consists of two breech mechanisms 16, 18 each including a rotatable cylinder which is formed with laterally open firing chambers of generally triangular shape. In the firing position the chambers are closed by a firing strap of the associated breech frame 20. The cylinders are driven, step by step and in unison by an electric motor 66 through a Geneva mechanism, the rounds being fired electrically through a cam operated firing circuit (Fig. 5a, not shown). The firing chambers of the cylinders are fed from hoppers 80. The booster ammunition rounds 42 are provided with a co-axially arrayed, perforated tube which forms an intermediate portion of the bore of the barrel. The booster ammunition rounds 42 are further provided with a yieldable, non-combustible case 46 and a combustible cover sleeve (Fig. 4, not shown) the latter to prevent the booster propellant 44 from entering the tube during handling of the rounds. In a further embodiment (Figs. 6 to 8, not shown) the primary breech mechanism comprises a rotatable cylinder having closed chambers and the secondary breech mechanism is of the open chamber type as previously described but the chambers communicate with the bore of the barrel through ports passing through the breech frame and the wall of the barrel. The cylinders are coupled for rotation through gearing. The booster ammunition rounds are provided with an opening along one of its sides, the opening being closed by a combustible cover sheet (Fig. 8, not shown). The gun may also comprise a multi-barrel assembly (Figs 9, 10, not shown). In this case a barrel is provided for each co-operating pair of firing chambers in two open chamber cylinders and the barrels are connected to the cylinders for rotation therewith. The booster ammunition rounds are as those shown in the accompanying Fig.

A refrigerator comprises an outer housing 2 containing a body of foamed plastics insulation 1 provided with inwardly directed projections 5 for supporting an inner casing 3 and for defining therewith an intermediate air space 4 communicating with the interior of the inner casing 3 through openings 6 and 7 to thereby allow air to circulate so as to prevent the formation of condensate in the insulation 1. The projections 5 may be of pyramid shape or alternatively may be in the form of horizontally extending trapezoidal section ribs interrupted in places to provide communication between the air spaces between the ribs. The openings 6 and 7 are in the form of lower and upper rows of slots and are covered by upwardly open channels 8, 9 integral with the inner casing 3. In another construction (Fig. 2, not shown) the rear of the insulation 1 has no projections and is spaced from the rear of the inner casing 3 to form a continuous intermediate air space containing a flat evaporator, a condensate drip channel and a fan. The fan draws air through a single upper air entry opening in the casing 3 into the intermediate air space and out through lower louvred openings. In a further construction, the evaporator is located in a continuous intermediate air space above an apertured roof of the inner casing 3 and a main evaporator is located under the roof of the inner casing.

Abstract: 1287827 Cap frames; guides; jets ZINSERTEXTILMASCHINEN GmbH 21 Sept 1970 [26 Sept 1969] 44873/70 Headings DID and D1F A spinning machine comprises a thread inlet duct 52, a pair of thread delivery ducts 25, 26 and a routing valve 47 for selectively connecting the inlet 52 with either of the outlets 25, 26. The routing valve 47 severs the thread as it moves to change the direction of thread feed. The thread is fed through the device by compressed air. As shown, there are two rotary routing devices 47, 47', the upper one of which can feed the thread through a waste thread discharge duct 55 or toward the main lower routing device. The lower routing device feeds the thread to one of two cap or cup spindles, (Fig. 1 not shown). Severence of the thread during change of direction of feed is ensured by sharp edges on the rotary parts 47, 47' and by spring-loading the adjacent guide ducts 53, 53' against the rotary parts. In an alternative embodiment (Figs. 5, 6 and 7 not shown) a routing device is used to feed the spinning units of a rotating carousel type spinning frame. The threads are fed through pivoted routing members (90) which sequentially pivot between adjacent delivery ducts 65 when the package being formed at the end of one delivery duct is fully wound. In Fig. 7 not shown the routing member feeding station A is about to pivot to station G. The adjacent delivery duct feeds a spindle (at station G) which is empty at that time, and spinning thereby continues. The full package at the end of the first delivery duct (station A) is doffed and that spindle becomes the adjacent empty spindle for the next preceding spinning station B. During pivoting between delivery ducts the routing members (90) pass over discharge ducts (77) which sever a short length of thread from the running threadline. The routing members (90) are mounted on a stationary table but their free ends engage with retractable rods (93) on the rotating carousel so that by the time they are ready to pivot at the completion of a package, the forward pivotal movement occurring prior to the commencement of that package has been reversed by the engagement of the routing member (90) with the rotating retractable pegs (93).
