Patent GB-523284-A (GB)
Title: Improvements in and relating to laundry presses
IPC: D06F71/08
Filed: 1938-12-30
Abstract: 523,284. Ironing-presses; machinery guards. KAHN. L. M., and KAHN, F. J. Dec. 30, 1938, No. 37905. Convention date, Dec. 30, 1937. [Class 138 (ii)] [Also in Group XXIV] An ironing-press comprises a lower buck 16, an upper head 20 resiliently supported from a vertically movable cross-head 34, and a movable intermediate unitary structure 18 comprising a buck 28 and head 30 for co-operation with the head 20 and buck 16 respectively, the upper head moving downward during upward movement of the intermediate member and upward during downward movement of the latter. Whilst the intermediate member is moving into contact with the upper head the lower buck is moved forwardly and upwardly into a convenient loading and unloading position, being restored to the pressing position before the descent of the intermediate member. Heavy pressure is applied to the upper press unit by a cam 118 operated by a fluid pressure cylinder 110 and a similar device is provided for the lower unit. The press may be partly or wholly automatic and in the wholly automatic form shown the control is effected by movement of a guard member 200 linked to the intermediate structure 18. On raising the guard, a rack 212 is lowered somewhat through a pinion operated by the guard. The movement of the rack operates a shaft 250 to swing locking catches 102, 104 out of their press-holding positions and the rack movement also operates in proper sequence valves controlling the supply of fluid pressure to and the exhaust of, the cylinders operating the pressure cams, and to and from the cylinders 56 provided for raising the cross-head carrying the intermediate unit 18. The intermediate unit is connected by cable 68 to the cross-head 34 so that the head 20 and intermediate unit are partly counterbalanced and move in opposite directions along the pillars 10. The supply of fluid pressure to and the exhaust of the cylinder swinging the lower buck to and from its loading and unloading position is also controlled by the rack movement. When the intermediate member is in the upper pressing position reverse movement of the guard raises the rack and thus operates the valves in the reverse direction for releasing the pressure between the upper elements, for swinging the lower buck back from its loading position, for lowering the intermediate member and for raising the lower buck into final pressure position. A locking device may be provided for preventing the upper head from falling if the cables break and other safety devices may be provided for preventing premature descent of the intermediate unit and for stopping the approaching press elements if an operator's hand is in danger of being trapped. These devices, one of which may be mounted on each head, are additional to the guard 200 and control the exhaust of the appropriate cylinder. In a modification, the upper head instead of sliding may be pivotally mounted but it is connected to the intermediate member by cables for movement therewith but in opposite directions as in the other form. Specification 514,743 is referred to.

Title: Improvements in or relating to apparatus for use in telecommunications exchange systems
IPC: H04Q3/00
Filed: 1965-09-07
Abstract: 1,101,588. Automatic exchange systems. SIEMENS A.G. 7 Sept., 1965 [7 Sept., 1964], No. 38083/65. Heading H4K. In an exchange system including a route simulation network for route selection through a switching network which is provided with more than one link between each pair of coordinate switches in adjacent stages, the process of route selection involves two steps the first of which results in the selection of a single switch in each stage and the second of which results in the selection of a single link between the chosen switches in each stage. If the switches of each and every adjacent stage are connected by more than one link, then the step of link selection takes place simultaneously in all of them. The system is applicable to the case where a fully-equipped exchange is provided for less than the theoretically possible full number of subscribers. The system is exactly the same as that described in Specification 1,077,679, but the claims relate to the feature of two step route selection. Particular description, Fig. 8.-The process of " switch selection " occurs as described in the above mentioned Specification. Each of the simulations of the links incoming to a same switch are multipled at the marking centre e.g. WK 311<SP>1</SP> via a respective auxiliary relay Lh viz relays Lh 3, Lh 4, Lh 5, and Lh 6 for the four links between a switch in the B stage and a switch in the C stage. These relays are connected through a chain consisting of their own contacts and the contacts of the link busy relays to the marking centre e.g. W.K. 211<SP>1</SP> of the proceeding stage. In operation, the marking signal reverted from control circuit ES, after the switch selection process, brings up those relays Lh which correspond to first free links whereby the relays Lh of lower priority are disconnected from the chain and the corresponding speech path relays C<SP>1</SP>, B<SP>1</SP> &c. are energized over their operating windings II. In response to the operation of these relays C<SP>1</SP>, B<SP>1</SP> &c., the link busy relays come up so as to release the simulation path through relays Lh and hence release the common equipment.

Title: Improvements in the surface treatment of edible organic material
Inventor: BINDER FRANCIS MARTIN
IPC: A23N7/00
Filed: 1962-10-11
Abstract: In a process for loosening the skins of vegetables, in which the vegetables are heated for a short time with high pressure steam and cooled rapidly by spraying with cold water, the steam is condensed so as to produce a partial vacuum in the treating chamber.  In one form, potatoes are placed in a basket in an autoclave having valves controlling a steam and cold water supply. The steam injection is started manually simultaneously with a timer.  The incoming saturated or superheated steam displaces the air in the autoclave through a valve in the lid.  When the steam pressure is equal to the cold water pressure, the latter is turned on manually or automatically and a one way valve prevents the steam from entering the cold water system. The potatoes may be maintained at 100 p.s.i. for ten seconds.  The timer then shuts off the steam and opens the steam exhaust valve.  As soon as the steam pressure falls below that of the water, cold water is sprayed on to the potatoes.  At 2 p.s.i. a one-way valve in the steam exhaust closes so that, on further cooling no air can be sucked back into the autoclave.  On opening the lid, the water sprays are shut off.  The skins are removed by tumbling the treated potatoes in a perforated drum having internal rubber bristles, through which drum cold water may be passed.

An automatic paralleling system for an A.C. generator comprises a transformer 10 having its primary winding energized from the generator 1 and a supply line 4, any phase, voltage or frequency difference being applied through a rectifier 11 and a Zener diode 15 to a transistor 16. Under asynchronous conditions the rectifier 11 output breaks down the diode 15, the transistor 16 conducts, connecting a conductor 42 to earth through a rectifier 22. The transformer 10 primary voltage is also applied to a pair of identical circuits, one of which comprises a potential divider 23, 24, a rectifier 26, a filter capacitor 27 and another potential divider 28 with its tapping connected to an over-voltage circuit comprising a Zener diode 33 connected to the base of a transistor 34. The tapping is also connected to an undervoltage circuit comprising a Zener diode 29, a rectifier 30 and a resistor 32. When the generator voltage is high, the diode 33 and hence the transistor 34 conduct, connecting the rectifier 36 to earth, and when the voltage is low the bias voltage on rectifier 30 is removed. The rectifiers 22, 30, 301, 36, 361 constitute a coincidence circuit and when they are all non-conducting the voltage on conductor 42 rises and applies a signal to a device 43 which effects closure of the circuitbreaker 6, 7. The device 43 is preferably a bistable circuit or an amplifier.
