Title: Improvements in and relating to extending ladders
IPC: E06C1/54
Filed: 1934-03-23
Abstract: 419,855. Ladders. AHERNE, J. F., Short Quay, and MANNING, T. J., The Rampart, both in Kinsale, Co. Cork, Irish Free State. March 23, 1934, No. 9225. Convention date, April 24, 1933. [Class 20 (ii).] A folding and extending ladder of the lazy-tongs type is provided with means whereby it may be automatically locked and maintained against a folding movement in any desired one of a multiplicity of different extended positions. Each side of the ladder is in the form of a lazy-tongs comprising two series of links 4,5 which are pivotally connected at their ends 8 and midpoints 6 as shown in Fig. 1. At the upper and lower ends, the links 4, 5 at each side are pivoted to a pair of links 2, 3 which are pivoted to a horizontal bar 1. The links 4, 5 are, preferably, of channel-section and have inserted longitudinal wood stiffeners to afford a convenient hand grip. The rungs 7 are, preferably, of T-section and are mounted between the pairs of links 4, 5 intermediate the pivots 6, 8. To provide the automatic lock when the ladder is extended, one or more of the links 4 is enlarged at the pivot 6 as shown at 9 in Fig. 4 for the reception of a fixed ratchet ring 10 having a set of teeth 12 disposed at two diametricallyopposed positions on the ring 10, and the corresponding link 5, Fig. 5, has attached to its centre a flat plate 13 having spring-controlled pawls 14 pivoted thereon for co-operation with the ring 10 when the members are assembled. The arrangement is such that when the ladder is extended, the links 4, 5 are moved in the direction of the arrows 16, 17 respectively, as shown in Fig. 4, and the pawls 14 and teeth 12 engage to lock the ladder against folding. The number of teeth 12 corresponds to the number of locking positions desired. To fold the ladder, the links 4, 5 are first moved further in the direction of the arrows 16, 17 until the pawls 14 clear the teeth 12. A balancing spring 20, which may be provided at each end of the top and bottom bars 1, is disposed in a metal housing 19, Fig. 6, being connected at one end to the housing and at the other end being adapted to bear against the links 2. Rollers may be provided on the uppermost links 2 to bear against the wall or other surface against which the ladder is placed. A stop to prevent over-extension of the ladder consists of a flat bar which is hinged to one member 4 and is provided with a series of holes for the reception of a pin adapted to enter also a hole in an adjacent member 5. The ladder may be fitted with a locking device at all the points of intersection of the members 4, 5 and also at the points of intersection of the members 2, 3 of the base-section.

Title: Baker's bread tin greasing device
IPC: A21B3/16
Filed: 1927-04-05
Abstract: 295,222. Evans, A. R. April 5, 1927. Grant of Patent revoked. Baking trays and the like, greasing.-A device for greasing bakers' bread tins consists of a container for oil or the like, a form for the reception of the tins keyed or otherwise mounted on the container to prevent relative rotation thereon, and means for feeding the oil under pressure from the container to the form. As shown in Fig. 1, the form 25 is carried on a pump plunger 13 which works in a barrel 12 in the container 10. The form consists of a perforated metal frame 26 having one or more layers of felt 27 on its sides. The plunger 13 has a central passage 14, and is prevented from rotating by screws 23 working in slots 24. Ball valves 17, 20 control the oil flow, and the form and plunger are normally retained in the elevated position by a spring 22. In use, a tin is placed on the form and pressed down, the plunger 13 descends and the oil ascends in the passage 14. The oil is deflected toward the sides of the form by a baffle plate 31 and excess oil runs on to triangular plates 29, which assist in holding the felt on to the form, and from thence, down the outside of the plunger into the container through an aperture 33. A filling- cap 11 is provided on the container 10. According to the Provisional Specification, the greasing is effected by contact with a form, or by a spray, or by both the form and the spray. The oil is delivered to the form or spray by gravity, air pressure or a pump.

Title: Improvements in centrifugally-armed percussion fuzes
IPC: F42C15/26
Filed: 1958-03-25
Abstract: 828,585. Ammunition fuzes. BREVETS AERO-MECANIQUES S. A. March 25, 1958 [April 6, 1957], No. 9584/58. Class 19(1) A centrifugally armed percussion fuze comprises a casing 3 closed by a plug 10 carrying a detonator 2 and a relay charge 1, a striker 4 being housed in the nose and a disc 5 containing a primer being journalled for rotation in the body of the casing. A diametral passage through the disc houses the primer, the disc being held so that the passage is not aligned with the charge 1 by a split ring 11 engaged in a groove 12 in the disc and slots 13 in extensions 9 of the plug 10. A movable shield 14 covering the relay 1 engages a notch 15 in the disc, so that the journals 6 of the disc are maintained at the forward end of slots 16 in the extensions 9 before a projectile furnished with the fuze is fired. On firing the projectile centrifugal force produced by the spin expands the ring 11, so that the disc becomes free to oscillate. As the disc moves, bringing the primer into alignment with the relay and the striker, it pushes the shield aside and the disc in turn is pushed rearwards by springs 17 bearing against the journals 6 until the primer is adjacent the relay and the fuze is armed for operation on impact. The primer comprises a casing 7 housing a priming charge 8 which may consist of a number of charges of differing compositions.

Title: Process for the production of cellulose ethers
IPC: D06M13/165
Filed: 1964-03-06
Abstract: Cellulose ethers are prepared by treating cellulose with the solution formed by dissolving a mono-, di-, or poly-halogeno ether in dimethyl sulphoxide, dimethyl formamide, or dimethyl acetamide. The ether may be e.g. a mono-a -halogeno alkyl ether wherein the alkyl group is a straight chain, or a bis-halogenomethyl ether of formula Halogen-CH2-O-(CH2)n-CH2-O-CH2 -Halogen. wherein n=0-9, or with di-(chloromethyl) ether, a ,b -dichloro-a ,b -dimethoxy-ethane, and the corresponding bromo- and iodo-ethers. Alkyl, alkenyl, cycloalkyl and aralkyl halogeno-alkyl ethers may also be used.  The cellulose should have a nominal moisture content of a few per cent.  The reaction may be carried out at room temperature.  The reactant is normally used in molar excess over the cellulose. The reaction may proceed till the cellulose is about 30% substituted.  Water-resistant or crease-resistant material results.  The cellulose may be in the form of powder, cotton linters, cotton wool, or cotton cloth, e.g. poplin.  The treatment is performed with or without shaking or stirring.  After treatment the material may be passed through rollers which return excess solution to the bath.  The solvent may be recovered.  The material may be washed with fresh solvent and dried at atmospheric pressure or in vacuo.  The degree of etherification may be determined by estimating formaldehyde formed by hydrolysis with HCl in acetonitrile under reflux.

Abstract: 1,021,566. Making perforated metal strip; punching; corrugating. ROHR CORPORATION. March 6, 1964 [Dec. 11, 1963], No. 9715/64. Headings B3A, B3E and B3W. A metallic ribbon 27 is perforated by needles 67, the tip portions of which are impaled within small rubber ribbon stripping cylinders 72, adjacent needles being staggered, the two rows thus formed being spaced apart by shims 74. An upper back-up plate assembly co-operates with the assembly 51 and comprises a metal bar 54 and a resilient ribbon stripper 58 attached thereto. The needle forms protuberances 56, the material of which doubles back on itself with progressive penetration due to the needle taper (Fig. 12, not shown). Simultaneously with the piercing process the ribbon is first yieldably clamped between the die members 25. The lower spring 38 is stiffer than the upper spring so that on further movement of the die member 23 the sidewall of a new corrugation is formed between tooth 24 of die 20 and a tooth 26 of die 19 when the upper member 25 bottoms on support 11. The remainder of the corrugation is formed between the upper and lower teeth 26 when the lower member 25 bottoms on support 10 (Fig. 1, not shown). The corrugations are stretched by a controlled amount by members 47, 48, to give the required spacing between corrugations and to compensate for any tapering of the corrugations over the width of the ribbon. The member 48 is adjustable at either or both ends relative to the support 11.
