Title: A method of and apparatus for forming cupped annular members for antifriction bearings
IPC: B21K1/04
Filed: 1934-01-29
Abstract: 419,570. Bending, stamping, and forging antifriction bearings. HOFFMANN MANUFACTURING CO., Ltd., New Street, Chelmsford, Essex.-(Assignees of Zimmerman, T., and Schreiber, A. ; 3040, Hart Avenue, Detroit, Michigan, U.S.A.) Jan. 29, 1934, No. 2970. Convention date, Jan. 27, 1933. [Classes 83 (ii) and 83 (iv).] A cupped annular member for an antifriction bearing, is formed from an annular blank 1 centred over a die 3 by a block 2 and resting by its lower outside edge only on a curved end portion 5 of a conical opening 6. A conical plunger 8 engages the upper surface of the blank to turn it inside out as the plunger forces it into the conical opening 6. The taper of the plunger corresponds to that of the opening 6 and the ring is extended axially as it is forced past the end of the conical portion into a cylindrical continuation 4 thereof, a bevelled shoulder 9 on the plunger engaging the upper end of the ring to force its lower end against an inwardly curved portion of the cylinder 4. A recessed plug 11 closes the lower end of the cylinder 4 to support the ring and yet permit the plunger to pass slightly beyond the end thereof. Excess metal flows upwardly between the shoulder 9 and the lower end of the opening 6 and is subsequently machined off leaving a bearing with a conical interior and a cylindrical exterior as shown in Fig. 7. A second blank may be cut from the discarded centre piece of the first blank to form a bearing of less depth, such a blank being disposed within the conical opening 6 and not being subject to the first operation of turning inside out.

Title: Improvements in or relating to the manufacture of mouthpiece cigarettes
Inventor: MOLINS DESMOND WALTER
IPC: A24C5/47
Filed: 1962-01-26
Abstract: 1,019,092. Cigarette making machines. THE MOLINS ORGANISATION Ltd. D. W. Molins and T. Rowlands. Jan. 24, 1963 [Jan. 26, 1962], No. 3097/62. Heading A2C. A method of making mouthpiece cigarettes by uniting a double-length mouthpiece portion M to two cigarette lengths C and then cutting midway through the mouthpiece portion to provide two mouthpiece cigarettes comprises the step of uniting the double-length mouthpiece portion to the two cigarette lengths by means of two relatively narrow adhesive uniting webs B formed from a single web which is longitudinally slit and the two web portions separated, the two webs B being then wrapped around an end portion only of the double-length mouthpiece portion and the adjacent end portion of a cigarette length. A single web of uniting material is fed from a supply reel and may be printed upon before being slit longitudinally into two webs 8a and 8b. The webs are separated to the required distance by guides 9 and 10, adhesive is applied to them and they are then cut transversely to make pairs of uniting bands B which are applied to the mouthpiece-cigarette groups. The groups are then cut midway through the mouthpiece to produce two filter cigarettes.

Title: Improved releasable support mechanism for supporting a liferaft or like load
IPC: B66C1/34
Filed: 1960-01-28
Abstract: 910,904. Hooks; hook fastenings. R.F.D. CO. Ltd., and EDWARDS, D. V. Dec. 22, 1960 [Jan. 28, 1960], No. 3131/60. Classes 44 and 89 (2). [Also in Group XXXIII] A support mechanism for a load, e.g. a boat, on the end of a cable secured to the support pin 18 comprises a latch 16 pivoted at 21 between plates 11 and 12 which releasably engages the shackle 20 of the boat. A locking member 17, which is pivoted at 25, is provided to lock the latch 16 in the supporting position, shown in Fig. 4, by engagement of a projection 26 in a recess 23 of the latch. A spring 27 mounted on the lock at 28 and the plate at 29 is arranged to bias the lock 17 to lock the latch in the boat supporting position and also to release the shackle 20 when the weight of the boat is removed, e.g. on contact with the water. This latter movement is initiated by an occupant of the raft pulling the lanyard 30 to move the locking member 17 out of engagement with the recess 23 during the descent of the boat. The latch 16 remains in the supporting position all the time it is loaded by the weight of the boat. The lanyard 30 is also provided so that the latch 16 may be moved to release the shackle 20 by the occupant of the boat if the latch does not automatically move to this position. The latch 16 may move to the release position under its own weight. The bias spring may be connected between the latch and locking members so as to act directly on the latch to move it to the release position when the load is removed. The locking member may be provided with friction rods which engage the supporting plates so that the member maintains the position to which it is pivoted. The locking member may be adapted to co-operate with a release member on the davit which moves it to the unlocking position at the commencement of the descent.

Title: Improvements in Projectiles.
Inventor: KUR EMANUEL FRANCIS
IPC: F42B12/44
Filed: 1916-03-02
Abstract: 103,891. Kur, E. F. March 2, 1916. Projectiles; projectile fuses.-Relates to incendiary projectiles for attacking aircraft and other objects, containing an inflammable gas capable of being ignited bv sparks caused by the abrasion of ferro-cerium. According to the invention, the incendiary charge in a shell is ignited by a longitudinally-sliding spring- controlled rod acting against a charge of ferro-cerium in a chamber provided with apertures to admit the inflammable gas or air Cavities charged with a mixture of aluminium powder and magnetic iron oxide communicate with the sparking- chamber. The projectile comprises a longitudinallv movable rod or striker A acted upon at its enlarged inner end by a spring B. The striker is roughened at the part a', and the end portion, as well as the hole in the nose of the projectile through which it passes, is preferably rifled. Within a chamber C, pyrophoric metal d, preferably attached to springs D, is arranged in contact with the roughened portion of the rod A, so that when the rod moves axially on discharge of the projectile and on impact upon a target, sparks are produced. The sparks ignite a readily inflammable substance which is provided in passages e, and this in turn ignites a charge of aluminium powder and magnetic iron oxide in one or more chambers E. Passages c communicating with the chamber C are formed in the nose of the projectile.

Abstract: 1286439 Vehicle seats RECARD A G 28 Nov 1969 [31 Jan 1969] 3184/72 Divided out of 1285360 Heading A4J [Also in Division F2] A vehicle seat 301 which is connected to a base by a front supporting leg 304 pivotally connected the base and the seat, is provided with a seat belt, one end of which is attached to the back of the seat and an energy dissipating means 308 which absorbs energy when the seat is moved by the weight of the occupant against the seat belt on sudden acceleration or deceleration of the vehicle. The height of the seat may be adjusted by altering the length of rod 307. In a second embodiment, Fig.2 (not shown) a rear leg (315) which is rigid with the seat has its lower end slidably mounted in an upwardly and forwardly inclined slot (320) in a bracket secured to the base (316) and the energy dissipating means (318) is connected between the lower ends of the front and rear legs. In a modification of the second embodiment, Figs.3-4 (not shown) a further supporting leg (331) with a slot (332) therein is connected between the centre of the seat part and the lower end of the rear leg (325), the energy dissipating means (328) being connected between the lower end of the front leg (324) and the slot in the further leg (331). A hook (333) is provided to hold the energy dissipating means in the upper end of the slot in the normal position of the seat and to release the energy dissipating means so that the seat may be tilted forwardly for access to the space behind the seat. In a second modification of the second embodiment, Figs.6-8 (not shown), the slot in which the rear leg is slidable is curved upwardly at the front end thereof, to tilt the seat backwards as it moves forwards, and the seat is held in its normal position by a stop projection (354) on the seat frame (342) resting on the front of the front leg and the front leg (344) is prevented from pivoting forwardly by a shearing pin (355) which forms the energy dissipating means. After this pin is sheared a further stop pin (356) comes into effect; both pins can be withdrawn laterally of the seat to allow it to be moved freely when desired. The shearing pin may be supplemented by other energy dissipating means such as a friction brake at one or each of the pivots of each front leg.
