Title: Improvements in and relating to printing presses
IPC: B41L15/02
Filed: 1921-05-19
Abstract: 184,869. Bullock, C. A. H. May 19, 1921. Addition to 173,041. Inking - apparatus. -Relates to inking- apparatus for the printing - press described in the parent Specification. In one form, Figs. 1 and 3<a>, the inking-roller 14 carried in the arms 11 pivoted to the hinged frame 9 engages, towards the end of its downward travel, cam-faces 6 on the ends of spring-controlled arms 5 pivoted at 7. During this motion a roller 19, carried by the arms 5 and positively rotated by a fixed quadrant 21, receives ink from an adjustable blade-and-roller sump 22<a> 24 and distributes it to the inking-roller 14. The sump is mounted in a spring-controlled sliding carriage 22b depending from which is a trip-lever 26 having a cam end 28 adapted to fulcrum on a fixed stop 27<a>, Fig. 3<a>, and a toe engaging a spring-controlled adjustable stop 27b. The sump roller 24 thus contacts with the roller 19 until, at a point determined by adjustment of the stop 27b the trip 26 is released and the carriage is retracted. Just before reaching its lowest position, the inking-roller 14 rolls on the surfaces 6 so that finally the rollers 14, 19, 24 are all out of contact. The complete inking,apparatus is removably fixed in position by screws 35. In another form Fig 4, ink from a drum 36 is carried to an endless band 18 by a roller 37 mounted on an adjustable spring arm 38 and pressed thereby into a slot in the drum. Alternatively, the roller 37 may be arranged inside the drum. The ink is spread over the band 18 by a roller 42 carried by pivoted spring-pressed arms 41, 43, the frame 9 in its downward travel engaging the arms 41. One side of the frame 9 also strikes a rod 44 and actuates a ratchet lever 30 for advancing the band 18 in the manner described in the parent Specification.

Title: Switchable permanent magnetic holding devices
IPC: H01F7/02
Filed: 1976-04-13
Abstract: 1512315 Magnetic holding devices M BAERMANN 13 April 1976 [19 April 1975] 15031/76 Heading H1P A switchable permanent magnet holding device for a ferromagnetic workpiece comprises (Fig. 1) a laminar stationary permanent magnet 1 with a circular opening centrally thereof, within which a rotatable permanent magnet disc 3 of similar thickness is positioned to present plane surfaces 5, 5a; 6, 6a. The stationary and rotatable magnets develop opposed pole pairs on their respectively opposed surfaces 5, 5a and 6, 6a whose polarities may opose or reinforce, and are divided by a dotted line defining a neutral zone. The magnets are of barium, strontium, or lead ferrite, and formed from the basic powder material by sintering, or injection moulding with a plastic binder and firing. High permeability polar plates 7 are positioned on each side of the magnet assembly 1, 3 and divided into two parts by non-magnetic material 8, e.g. brass or aluminium. Bores 9 accept non-magnetic fixing screws (not shown) and the pole plates concentrate the magnetic force to retain a ferromagnetic object when the polarities of the stationary and rotatable magnets reinforce in corresponding areas of the polar plates, and to release it when on rotation by 180 degrees the polarities are opposed. Lesser rotation operates to vary the retaining magnetic force. The magnet 3 and the pole plates 7 have central apertures for a control shaft and handle (not shown). Plural assemblies may be arranged in tandem packs (Fig. 2, not shown) so that corresponding retaining surfaces of the pole plates present opposite polarities to a ferromagnetic workpiece. In a modification (Fig. 3, not shown) each of the stationary and rotatable magnets is provided with four pairs of poles of opposing polarities and the pole plates are each divided into four parts by cruciform non-magnetic elements, so that the rotatable magnet is turned through 90 degrees between the switched on and switched off conditions of magnetization. The circumferential surfaces of the stationary magnets interposed between the pole plates may be surrounded by a non-magnetic material, e.g. aluminium (Fig. 4, not shown) to present a plane surface. In a further modification plural tandem packs (Fig. 2, not shown) may be assembled side by side perpendicularly to the axes of rotation of the movable magnets with their operating shafts geared together (Fig. 5, not shown).

Title: Improvements in or relating to the production of montan wax products free from asphalt
IPC: C10G73/00
Filed: 1932-05-28
Abstract: Montan wax products free from asphalt are obtained by saponifying the crude or deresinified wax with alkalies and/or earth alkalies, dissolving out the alcohols and soaps of the wax acids by lower alcohols and ketones or by formic or acetic esters of the alcohols, and if required acidifying the soaps, maybe after separation of the wax alcohols.  The saponification and extraction may take place simultaneously.  Solvents specified are methyl, ethyl, and propyl alcohols, acetone, and ethylmethyl-ketone.  For example, 200 kg. of deresinified wax, 1000 litres of 96 per cent. ethyl alcohol, and 30 litres of 50 per cent. aqueous caustic soda are boiled under a reflux condenser or are heated to 100--110 DEG  C. under 5 atmos. pressure for 3--4 hrs., and allowed to cool and settle; the upper layer, alcohols and soaps, is mechanically separated from the lower layer, asphalt, heated to distil off solvent, treated with sulphuric acid to decompose the soaps, washed free from acid, and dehydrated in vacuo. The product may be further refined by the material known under the Registered Trade Mark " Carboraffin " or other adsorbent, or by oxidizing agents, e.g. chromic acid as described in Specification 305,552, [Class 91, Oils &c.]; it may be bleached or the acids thereof converted into alcohols or hydrocarbons by treatment with hydrogen at high pressures and elevated temperatures in presence of catalysts, and the acids may be esterified with mono- or poly-hydric alcohols or converted into metal or other compounds containing the -CO- group.  The asphalt is freed from alkali; it is characterised by high M.P. and viscosity.  In a second example, 50 kg. of deresinified wax, 5 kg. of caustic soda, and 15 kg. of water are maintained at 160 DEG  in an autoclave for 4 hrs., and the product treated with 160 kg. of boiling acetone whereby 7 kg. of wax alcohols are extracted.  The solid residue is treated at 70 DEG  C. with 200 kg. of 80 per cent. ethyl alcohol, allowed to cool and settle, and treated as in Example 1.  Specifications 304,150, [Class 91, Oils &c.], and 354,334 are referred to.
