Title: Improved apparatus for dispensing towelling
Inventor: HOWLETT EDWARD JOHN
IPC: A47K10/28
Filed: 1965-12-31
Abstract: 1,137,003. Towel roll dispensers. STRATTWELL DEVELOPMENTS Ltd. 24 Jan., 1967 [31 Dec., 1965], No. 55373/65. Heading A4G. In a towel roll dispenser rotation of delivery roll 7 energizes a power-operated mechanism 14 which is unlocked on releasing tension on the clean towelling whereby soiled towelling is withdrawn into the cabinet 1 at 31. On pulling towelling 10 over U-member 30 a U-member 25, 26 is raised from the front cabinet face 3 so that, via cam 27 and linkage 22-24, a pawl 21 engages a ratchet wheel 20 to lock a hollow soiled-towel retraction roller 15. As towelling is delivered between pinch roll 9 and roll 7 a chain 13 winds up a spring attached within roll 15. On releasing the clean towel, member 26 falls under a spring or gravity and allows spring 29 to displace pawl 21 so that roll 15 rotates under the energized spring within and retracts soiled towelling around the back of a towel trough 11 over roll 15 and into space 31, the clean towel lying tight around the bottom front of the cabinet. The next withdrawal of clean towelling winds the soiled towelling on to roll 32 via frictional drive from roll 12. A presser roll 33 for roll 15 is linked at 34, 36 to an upper casing door 2 to facilitate rethreading while a pawl 37 locks ratchet wheel 20 when a lower door 3 is opened. The dispenser may or may not be of the kind in which the delivery roll is locked after a predetermined length of towel has been dispensed.

Abstract: 1275988 Isolators WESTERN ELECTRIC CO Inc 18 Nov 1969 [22 Nov 1968] 56380/69 Heading H1W An isolator for given frequency microwaves employing the properties of a gyromagnetic material, preferably ferrite 16, 17, which fills a conductively bounded channel or wave-guide, has applied a steady magnetic field H DC  with a field gradient across the channel such that the field strength varies from a value less than to a value greater than the field producing gyromagnetic resonance for the material, and the microwaves are applied with their electric vector transverse to the field gradient. The field H DC  is stated to distort the magnetic field of the microwave within the ferrite such that the longitudinal and transverse components are equal in amplitude in a relatively broad region that substantially coincides with the region of resonance. In combination with a microwave strip line an isolator channel may be disposed between the centre conductor and one or each ground plane and as in Fig. 1 the ferrite is bounded by the ground planes 10 and 11 and by side partitions 13 and 14 and is divided by a conductive central divider 15 connected to the centre conductor 12 of the strip line. Capacitative stubs 18, 19 are provided to improve the impedance match. In further embodiments the ferrite is bounded by a conductive foil and may be coupled to the centre conductor 12 by a dielectric material.

Abstract: 1,193,440. Extruding. VICKERS Ltd. 15 March, 1968 [16 Dec., 1966], No. 56558/66. Heading B3P. A hydrostatic extrusion apparatus comprises a pressure vessel 1 having an open ended axial bore 2, 3 defining an extrusion chamber containing hydrostatic fluid 25, a first axially bored ram assembly 9 entering one end of the extrusion chamber and having means 13 for clamping a billet 11 passing therethrough, a second axially bored ram assembly 17 entering the opposite end of the extrusion chamber and carrying an extrusion die 18, and means 5, 6 for pressurizing the hydrostatic fluid 25 to extrude the billet through the die. The billet 11, which may be continuous or may comprise a series of billets, is fed through the bore 10 by a loading ram 12 or by feed rollers (45), Fig. 6 (not shown), after the hydrostatic pressure has been relieved; a spring-loaded split taper collet is used with the ram 12 when extruding continuous billets. Rams 9, 10 are actuated by intensifier pistons 7, 15 connected through pipe 22 with a pump 23 and a pressure release valve 26. Ram 9 has a thin lip 24 which is closed upon the billet by the hydrostatic pressure to provide a seal. The lip 24 may also be used to clamp the billet or the loading ram 12 may serve to support the billet against axial movement. The rams are retracted by pressure fluid admitted to chambers 28, 29 from pumps which-may also control the forward speed of the rams. Alternatively auxiliary single or double acting cylinders may be provided for this purpose and may also be used to determine whether the billet is subjected to positive axial loading in addition to the hydrostatic pressure. The ram 9 may be alternatively of smaller diameter than the ram 17. Instead of the vessel 1 being fixed it may move axially over one of the rams which is then fixed. In a modification, Fig. 2 (not shown), the stepped bores 2, 3 are provided in separate parts (32), (32) of the pressure vessel, or the step between the two parts of the bore may be conical. In another modification, Fig. 4 (not shown) the pipe 22 leading to the outer ends of both intensifiers 4, 5, contains a pressure transformer (35). In another embodiment, Fig. 5, the ram 9a and the vessel 1 are fixed and the ram 17, actuated by piston 15a, slides within a sleeve 39 connected to an annular piston 40. Both sides of piston 15a are interconnected by pipe 22 containing a pump 23 and a pressure transformer 35 consisting of two swash plate units 36, 37 mechanically connected at 38 and whose swash plate inclination can be controlled automatically. Alternatively the sleeve 39 may surround the ram 9a. In a modification, Fig. 6 (not shown), the vessel 1 is movable axially with the ram 17 or independently thereof. In another modification, Fig. 7 (not shown) the sleeve 39 is fixed.

In position (ii), rotation of the stem in the direction of arrow 51 causes diametrically-opposed projections 54, on an axially-slidable clutch wheel 16, to engage an adjusting lever 57 which pivots against the action of a spring 61 so that end 64 of the lever indexes a day star wheel 15. Simultaneously a projection 65 on the lever 57 enters the path of the teeth 53 of a date ring 14 so that clutch wheel teeth 46 slide over the teeth of the date ring without the latter being indexed. With the stem still in position (ii) rotation thereof in the direction of arrow 50 causes teeth 46 to index the date ring 14, but projections 54 do not pivot lever 57 since they merely bend it as shown in Fig. 5. In position (iii) of the stem, teeth 45 on the clutch wheel 16 directly or indirectly drive a minute wheel 47. In this position and also in position (i) of the stem the projections 54 are positioned axially clear of lever 57. In the modification of Fig. 6 (not shown) the spring 61 is omitted and the end of the adjustment lever engaged by projections 54 moves between flanges (72, 73) provided on the clutch wheel. The other end of the adjustment lever is forked and engages the first arm of a further lever (75), the second arm of which, when the stem is in position (ii), can index the day star wheel 15. In a further modification Fig. 7 (not shown) undisclosed means are provided which, upon rotation of the stem in either direction in position (ii), effects the corresponding desired axial movement of the clutch wheel. Projections 54 may be integral with clutch wheel 16 or on a cam ring in frictional engagement therewith. In an alternative arrangement four pegs (91) Fig. 11 (not shown) replace the two projections 54.
