Title: Improvements in track brakes
IPC: B61K7/04
Filed: 1934-03-12
Abstract: 435,312. Track brakes. VEREINIGTE STAHLWERKE AKT.-GES., 67, Breitstrasse, Dusseldorf, Germany. March 12, 1934, No. 7818. Convention date, March 14, 1933. [Class 103 (i)] Track brakes operated by the weight of the vehicle are mounted on rocking supports 3 inclined to the vertical and are connected to the driving means by a crank 5 and a releasable coupling. The supports 3 may be inclined in the direction of travel of the vehicle or in the opposite direction. The weight of the brake is taken by springs 12. The links may be arranged in the centre or on both sides of the track. The brake is operated through an electromagnetic clutch and worm drive by an electric motor. The motor is automatically disconnected in the braking position and when the clutch is de-energized to release the brake the motor is switched on and runs idly ready for the coupling to be re-energized to move the brake to braking position again. To render the brake inoperative the motor is reversed and in the inoperative position the motor and coupling are de-energized.

Title: Vehicle body with occupant head-protective curtain
IPC: B60R21/06
Filed: 1974-02-21
Abstract: 1452534 Seat head rests GENERAL MOTORS CORP 21 Feb 1974 [7 March 1973] 7954/74 Heading A4J [Also in Division B7] A device for protecting the rearwardly moving head of a passenger comprises a set of parallel tensioned flexible woven straps (or lengths of a single strap) which are normally edge on to the head. In the event of a collision the straps are turned, either by impact of the head or by other means, to form a closed surface which suffers plastics deformation to arrest the head's movement. The arrangement ensures that there is little obstruction to vision in normal circumstances. As illustrated in Fig. 1a, horizontal straps 16 are located in a frame 15 above a front seat. Cords 17 pass through and are secured to the straps to maintain this parallel spacing. As illustrated in Fig. 1b, straps 17a are located above the rear seat and are anchored at their ends to the sides of the vehicle body. In an alternative arrangement (Fig. 5), the straps are vertical, and sets of straps 116, 216 are located over the side window of the vehicle to protect against sideways collision. The straps may, as shown in Fig. 5, be so angled that they interfere with vision to a minimum extent. When each set is made up of separate straps, the ends of the straps may be rigidly anchored by yokes to the vehicle body or to a seat frame. Alternatively the ends of the straps may be pivotally mounted so that the straps can be individually set or so that they can pivot in unison in the manner of a venetian blind. In one arrangement of this kind, Fig. 20 (not shown), the normal angle of the straps can be set manually, the straps then being turned by the impact of the head in a collision. In this case, the straps can also be set to act as a sun blind. In another arrangement, Figs. 13 and 14 (not shown), the straps are spring-biased towards their closed position but are normally retained in their open position by a solenoid armature which is automatically withdrawn in the event of a collision. In yet another arrangement (not shown), the straps are automatically turned by a motor in the event of a collision. When one continuous strap is used, the ends of the strap may be secured to tensioning springs 40, 41 (Fig. 15). When the head hits the strap, the springs elongate to the point where shackles 38, 39 co-operate with a yoke 36 to prevent further movement. Alternatively as shown in Fig. 18, the ends of the strap may be rigidly anchored while the bights between individual runs of the strap pass over portions of a cushion 42 of resilient material.

Title: Improvements in the Sterilization of Food Products.
Inventor: ASHTON THOMAS RICHARD
IPC: A23C9/152
Filed: 1966-02-23
Abstract: 1,164,275. Removing cooked flavour from sterilized foods. EXPRESS DAIRY CO. (LONDON) Ltd. 14 Oct., 1966 [19 Oct., 1965; 2 Nov., 1965; 23 Feb., 1966], Nos. 44156/65, 46360/65 and 7981/66. Heading A2D. The removal of the initial cooked flavour produced in food products when sterilized by an ultra high temperature process is controlled by holding the product, after sterilization, under such conditions of temperature and/or pressure and controlled reduced dissolved oxygen content so as to support oxidation of the sulphydryl and other oxidizable compounds that contribute to the initial cooked flavour, the amounts of oxygen being so controlled that at the end of such oxidation little or substantially no dissolved oxygen remains, thus precluding subsequent long-term oxidative flavour deterioration of the product. The food products may be milk and milk products, creamed rice, soups, fruit juices and purees, alcoholic and non-alcoholic beverages, and baby foods containing cereals. In the examples: (1) a food product is sterilized at about 280‹F. for 1 to 2 seconds, divided into two streams one of which is cooled by indirect heat exchange under pressure to retain its dissolved oxygen and the other cooled by flash evaporation to substantially remove its dissolved oxygen, and the cooled streams are recombined for sterile packaging in gas impermeable containers; (2) separate streams of food product with (a) substantially no oxygen and (b) normal oxygen contents are heat treated and cooled by indirect heat exchange under pressure, the streams being combined before heating, between heating and cooling, or after cooling; (3 and 4) a food product is heated by indirect heat exchange and cooled partly by flash evaporation and partly under pressure; (5) a food product heated by steam injection is divided into two streams one of which is cooled by flash evaporation and then combined with the second stream, optionally after cooling the second stream under pressure.

Abstract: 1,134,133. Coating silica with carbon. QUARTZ & SILICE. Feb.24, 1966 [Feb.24, 1965], No.8234/66. Heading C7F. Silica fibres as they are drawn from a die are coated with carbon by pyrolitic deposition from a carbonaceous atmosphere such as acetylene, propane, butane and methane, the fibres being electrically resistance heated during the coating. According to Fig.1 silica rod 12 is heated by ring heater 14, drawn to fibre 17 and passed through a hydrocarbon atmosphere in a refractory tube 19 which may be 5-30 cms. long. At the tube exit the coated fibre passes through a metal or graphite contact ring 23 which may be heated and the coated fibre may either be sprayed with a stream of inert gas or passed into a cooling tube containing a nitrogen atmosphere. A power supply 25 is connected between the contact 23 and the ring 14 and a potential of 1, 000 volts is applied to the fibre. Instead of contact 23 electrical contact may be made by ionizing the air surrounding the fibre with a flame or with a radioactive material. The fibre is generally maintained at 1000‹-1500‹C. during coating. The coating thickness may be built up by passing the coated fibre through a second tube containing a hydrocarbon atmosphere.
