Abstract: 1,245,062. Cooling engines in motor vehicles. HONDA GIKEN KOGYO K.K. 21 Aug., 1969 [9 Sept., 1968; 24 Sept., 1968], No. 41733/69. Heading B7H. [Also in Divisions F1 and F3- F4] An air cooled internal combustion engine 3 is mounted transversely at the front of a vehicle in a compartment 1, whereby air ducted to a blower 15 is forced by the blower through passages 9 and 12 surrounding the cylinder head and cylinder body respectively. Internal and external walls of the cylinder head and cylinder body form the passages through which the air is forced and that from the cylinder head is conveyed via ducting 17 to the passenger compartment 2 of the vehicle, its flow being controlled by valve 21. The cylinder body passage is divided by vertical plates (19), Fig. 3 (not shown), extending between the inner and outer walls and between which the air is deflected upwardly, where it is ejected around the cylinder head to assist further cooling of the head. The flow from the blower is through two separate ducts to the respective passages in the cylinder head and cylinder body and a restriction may be inserted in the duct leading to the cylinder body portion so that the flow to the cylinder head is greater than that to the cylinder body. A plate 22 screws the top of the cylinder body portion and prevents air entering the compartment 1 through frontal opening 5 from deflecting the air flowing upwardly from the cylinder body around the cylinder head. Specifications 1,245,061 and 1,245,063 which disclose similar arrangements are referred to.

Abstract: 1451727 Window regulating mechanism FORD MOTOR CO Ltd 27 Sept 1974 [17 Oct 1973] 41999/74 Addition to 1336540 Heading E2M  In a vehicle window regulating mechanism coupled to a vehicle window panel 11 that is divided vertically into independently movable, substantially co-planar, visibility (14) and ventilating (13) sections, a gear sector 19 is pivotally mounted on a first pivot shaft carried by a mounting plate 16 fastened to the inside of a vehicle door and a first regulator arm 23 is freely swingable intermediate its ends on a second pivot shaft 22 journalled in the mounting plate 16 and is coupled at 26 to the ventilating section 13. A second regulator arm 24 is fixedly coupled to the second pivot shaft 22 for swinging movement as the second shaft rotates in the mounting plate and the other end of the second regulator arm 24 is coupled to the visibility section 14. As a drive pinion 18 is rotated in an anticlockwise direction the gear sector 19 moves in a clockwise direction, as viewed in Figure 1, such that the action of a first (29) and a second (34) cam follower mounted on the gear sector 19 operating in cam slots 28 and 36 in the arms 23 and 24 respectively enables the ventilation section 13 to be first lowered to a predetermined position before the visibility section 14 starts to open or move downwardly. Upon rotation of the gear sector in the window closing direction, the visibility section 14 reaches a fully raised position before the ventilation section 13 starts to rise. The window may be operated electrically by motor means (not shown).

Title: Magnetic separator for mixtures of magnetic and non-magnetic material
Inventor: TENPAS EMERSON J
IPC: B03C1/22
Filed: 1966-09-26
Abstract: 1,117,985. Magnetic separators. ERIEZ MFG. CO. 26 Sept., 1966, No. 42944/66. Heading B2J. In a magnetic separator for separating magnetic and non-magnetic materials from a mixture thereof, the mixture is fed from a vibratory feeder 15, Fig. 1, to a lower belt conveyor 8 by which it is carried below an upper belt conveyor 9 above the lower run of which is arranged a magnetic concentrator 11 comprising permanent magnets having poles which extend across the conveyor and are of alternate polarity along the length of the conveyor. The pulley 7 supporting one end of the conveyor 8 has spaced U-shaped or horseshoe permanent magnets around its inner periphery so that poles of alternate polarity are circumferentially spaced around the pulley and extend from one side of the pulley to the other. This arrangement of polarity of the magnets of the pulley 7 and of the concentrator 11 causes agitation of the magnetic material on the conveyor 8 as the mixture is carried between the conveyors, thereby facilitating separation. When the mixture reaches the end of the conveyor, the magnetic material is caused by the magnetic concentrator 11 to adhere to the upper conveyor 9 which carries that material to the end of the concentrator 11 where it is dropped into a hopper 2, while the non-magnetic material falls off the end of the lower conveyor 8 into a hopper 3. The pulley blocks 10 supporting the pulleys 4, 5 of the upper conveyor 9 are vertically adjustable on supports 30, 30<SP>1</SP> in order to vary the spacing between the lower run of the conveyor and the magnetic concentrator 11 and hence to increase or decrease the strength of the magnetic field through the belt. In addition, or alternatively, the strength of the field may be varied by vertical adjustment of the magnetic concentrator by means of a nut and bolt arrangement. Feeding the mixture may be by means of a hopper or, as shown, a conveyor 33 discharging via a chute 34 into the vibratory feeder 15. In the modification shown in Fig. 4, the vibratory feeder 315 feeds the mixture to the lower level of the pulley 307 of the lower belt conveyor 308 so that the magnetic material is picked up by the conveyor 308 and carried along its upper run while some of the non-magnetic material falls down from the end of the feeder 315 into a suitable hopper. The remainder of the non- magnetic material is entrained with the magnetic material and is separated in the manner described with reference to Fig. 1.
