Title: Improvements in or relating to combine harvesters
IPC: A01F12/00
Filed: 1966-03-09
Abstract: 1,143,464. Threshing machines, TEXAS INDUSTRIES Inc. 9 March, 1966 [18 March, 1965], No. 10440/66. Heading A1F. In a combine-harvester means are provided for transferring some of the threshed products to a supervisory station where the efficacy of the threshing action can be checked and remedial action taken if necessary. The machine is conventional, except for the provision of a trough (24) arranged beneath the rear end of the strawrack (5) to receive a sample of the rejected straw and to transfer it, via a duct (23) oscillated by a cam (26) to the lower end of an endless conveyer (14) which carries partly-thrashed product, falling through the dressing-shoe sieves (6), back to the threshing drum (3). The conveyer, which is partitioned longitudinally so that the two samples do not mix, comprises an endless chain carrying paddles which push the products along a wall of the housing. Near its upper end, the housing has a transparent window (28) through which the operator of the machine can observe the products passing, before they fall through a shoot (29) communicating with the elevator (2) feeding the threshing drum (3). In the machine described, the operator is the driver of a self-propelled combine and the window (28) is adjacent to the driver's seat (27), but the arrangement can also be applied to stationary threshers.

Title: Improvements in or relating to apparatus for withdrawing a succession of single sheets, of paper or like material, from a pile of the said sheets
IPC: B65H3/06
Filed: 1925-04-23
Abstract: 250,396. Rose, W.., and Rose Bros. (Gainsborough), Ltd. April 23, 1925. Sheet-separators; pile supports. - Sheets are separated from a. pile 3 contained in a magazine 1, which is adjustable vertically and horizontally, by means of a rotary knurled or grooved friction roller 15 carried by a rotating yoke 11, 17 driven by an electric or other motor. The shaft 13 of the roller 15 is fitted with a spur gear 14 which engages a fixed wheel 16, so that the roller 15 is driven by epicyclic gearing and rotates quickly to feed the bottom sheet past an adjustable plate 17<1> into engagement with sheet-forwarding devices such as positively driven rollers 20. 21. The sheets normally rest on ledges 4 attached to the magazine 1, and to prevent double feed a needle 27 of resilient material such as tempered spring-steel is arranged to pierce the bottom sheets of the pile. The needle 27, Fig. 7, is vertically adjustable by a screw 29 in a holder 28, and is clamped in adjusted position by a screw 30. The holder 28 is adjustable longitudinally relatively to a bracket 31 on the magazine 1 by means of a screw 34, and is clamped in adjusted position by means of a screw 35. The magazine 1 is mounted for adjustment as shown in Fig. 4. A tongue-shaped projection 41 on the magazine 1 engages a vertical groove in a crossmember 36, and is vertically adjustable by means of a screw 42 engaging a threaded opening in the member 36. To effect horizontal adjustment, the cross-member 36 is formed with a groove 37 which is engaged by a bar 39 secured to a fixed bracket 40, and the cross-member 36 is movable longitudinally on the bar 39 by means of a screw. A lock-nut 48 holds the member 36 in its adjusted position.

Title: Improvements in drive mechanisms for injection moulding machines
IPC: B29C45/68
Filed: 1959-03-26
Abstract: 871,637. Injection moulding machines. HEHL, A., HEHL, K., and HEHL, E., [trading as ARBURG FEINGERATEFABRIK O. H. G. HEHL-SOHNE]. March 26, 1959 [June 7, 1958], No. 10728/59. Class 87(2). Mechanism for moving and clamping together the mould parts of an injection moulding machine comprises a clamping plate guided for movement between a fixed clamping plate and thrust plate along parallel bars, a pneumatically or hydraulically operated drive unit which is movable about a pivot, the pivot being adjustably connected to the thrust plate to adapt the maximum opening distance between the clamping plates to the size of the mould, and linkage operatively connecting the drive unit with the movable clamping plate, the said pivot having its axis lying consistently in the mean plane of the mechanism. Air or hydraulic pressure in a cylinder 23 moves a clamping plate 4 along guide bars 2 without tilting it. The guide bars extend between the stationary clamping plate 1 and the thrust plate 5. Some of the components of the mould (not shown) are secured to the movable clamping plate and others to the stationary clamping plate. A pin 6 passes non- rotatably through the thrust plate 5 and is held in position by lock-nuts 7, 8. A double-armed lever 28 is pivoted at 9 to the pin 6 and forms part of a linkage, shown in Fig. 2 in the position where the clamping plates are opened, which comprises also links 17, 19, 21, with duplicate links at the rear, not shown. Pressure fluid in the cylinder 23 causes the piston-rod 30 to descend and the lever 28 to turn about the pivot 9 to a horizontal position, Fig. 1, with the result that the links 19, 21 swing apart, the cylinder 23 moving to a position where its axis is perpendicular to the guide bars. The divergent movement of the levers 17, 18 (not shown) relatively to the double-armed lever 28 is limited by an abutment 27 (which is integral with the double-armed lever 28 and connects its arms) engaging an abutment edge 38 formed on the pin 6. The closing movement of the levers 17 and 18, relatively to the double-armed lever 28, is limited by an abutment edge 39 on the abutment 7 engaging the pin 6. By shifting the pin 6 one way or the other and clamping it by the lock-nuts 7, 8 the distance between the clamping plates may be adjusted to the size of the mould.

In order to transmit rotary motion from an external knob 1 to an element 5 of an instrument such as a potentiometer in a fluidtight housing 7, one wall 4 of the housing is formed as a flexible metallic diaphragm soldered to a non- rotatable axially-movable member 3 having screw connections with the knob 1 and the element 5. As shown, the knob 1 is rotatably mounted in a neck 7<SP>1</SP> of the housing 7 by means of a flange 1<SP>1</SP> and has two projections 2 engaging a double-start thread on the outer end of the member 3. Rotation of the member 3 is prevented by guides 31, 32. The inner end of the member 3 has a single or double-start thread engaging a projection on the element 5, which is rotatable in a support 8. The thread on the inner end of the member 3 is of a pitch different from, preferably coarser than, that on the outer end.

Abstract: 1,145,285. Coating with metals; electrolytic cleaning and charging with hydrogen. NATIONAL RESEARCH DEVELOPMENT CORP. March 14, 1966 [March 17, 1965; Sept. 20, 1965],Nos. 11302/65 and 40087/65. Headings C7B and C7F. In the electroless deposition of Pt or Rh on a Ni or Ni-Fe surface, hydrogen is first introduced into the surface by either contacting with an acid, e.g. hydrobromic or sulphuric or subjecting to a cathodic treatment. The cathodic treatment may be followed by a shorter anodic treatment to make the hydrogen concentration uniform. In an example a nickel sheet is subjected to a cathodic current of 0À06 amps/sq. cm for 2 minutes in a bath of sulphuric and hydrochloric acid and then to an anodic current for 15 seconds. Alternatively an alkali e. g. sodium hydroxide, bath may be used for both a cleaning and hydrogen charging process. The nickel surface may be formed by electroplating on copper using a bath as follows:- (grams) NiSO 4  7H 2  O 60; NaCl 2‹4; boric acid 4‹0; MgSO 4  7H 2 O 8‹8. The electroless plating may be carried out using a solution of chloroplatinic acid or rhodium trichloride with hydrochloric acid, ferrous sulphate and ammonium iron alum as a reclose liquid.
