Abstract: 286,371. Fitzpatrick, H. D., (U.S. Slicing Machine Co.). Dec. 4, 1926. Cutting slices in succession.-In a slicing-machine of the type in which the substance is placed on an inclined reciprocating support whereby it is fed to the slicing knife, a slice receiver is arranged to reciprocate in timed relationship with the support. As shown in Fig. 2, the slice receiver is connected to the reciprocating support and comprises an inclined trough 48 parallel to the similarly shaped support 37 for the substance, and an abutment plate 49 against which the slices rest. The plate 49 is carried by a rod 42 which also carries prongs 45 to engage the substance, slots being provided in the trough 37, 48 to allow the prongs and abutment to descend in unison as slices are severed. The rod 42 is depressed by a handle 46 to feed the substance towards the knife which is supported in a goose-neck bracket 13, shaped to leave a clear space under the knife. The bracket carries the motor 24 and driving-gear 22, 23 for the knife. A similarly shaped bracket supports a stop plate over which the substance moves on its way to the knife, and which regulates the slice thickness. The plate is of known construction and is pivotally mounted and adjusted by cam means. The troughs 37, 48 are ribbed to minimize friction and are carried on guide rods 12 by brackets 38, 47. The knife 15 is partially enclosed by a slice deflecting plate 25 secured to the knife bracket, and partially by a plate 26 which is extended to form a guard for the knife-driving gear. The knife 16 is of ring form and is screwed to a supporting spider 20 having a belt groove 21. A bearing-bush 16 is held on a stud shaft 14 by a disc 17 secured to the shaft 14 by a screw 18. A stationary cover plate 19 is screwed to the disc 17 and lies within an annular recess near the cutting edge of the knife 15.

Title: Improvements in phase-shifting networks particularly applicable to radio guiding systems
IPC: H03H7/18
Filed: 1939-12-01
Abstract: 536,950. Impedance networks ; directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., and McPHERSON, W. L. Dec. 1, 1939, No. 31247. [Classes 40 (iii) and 40 (v)] A phase-shifting network, particularly applicable to radio beacon systems, is designed to give alternative phase shift values according as a single connection is made or broken, the impedance being the same in each case. The invention depends on the fact that the T-networks shown in Figs 1a, 1b when connected to a load of impedance Z present the same impedance, which may be made equal to Z if X 1 , X, are suitably related, and produce equal and opposite phase chances. As shown in Fig 2a, the series arms EF, FG constitute circuits which are resonant at the input frequency, and the inductances X4 form an antiresonant circuit with a shunt condenser when the contact S is closed. In the latter condition, therefore, the arms EF, FG are of very high impedance and the network is equivalent to that of Fig. 1a. When the contact S is open, on the other hand, the arms EF, FG are of very low impedance and the network is equivalent to that of Fig. 1b, provided the condenser X 3  = 2X 2 X 1 /(2X 2 -X 1 ). The reactance values X4 are not related to the phase shift nor to the load impedance, and are chosen to give the best impedance values with the switch S open and closed. In a modification, the anti-resonant circuit is inductively coupled to the arms EF, FG. The network may be used as an impedance matching network between two impedances Z 1 , Z, by making X 1 , X, numerically equal to each other and to Z 1 , Z 2 , in which case the opening and closing of the contact S alters the phase shift by 180 degrees. The network may be generalized to give any desired phase shift values, the elements X 1 , 2X 1 , X 2 , X 3  being replaced by reactances dependent on those values. Fig. 5 shows a particular form which gives zero phase shift with the contact S open. The networks described are suitable for use in connection with a radio beacon operating on the " dot-dash principle, in which a part of the aerial system acts alternatively as a reflector or director in accordance with the phase of the energy supplied thereto. The change from one radiating condition to the other is thus effected instantaneously by opening and closing of the contact S, which may be operated as required by a control relay.

Title: Control valve for an automobile transmission system of an  automobile
IPC: F16H61/06
Filed: 1975-07-28
Abstract: 1473254 Change-speed control AUTOMOBILWERKE EISENACH VEB 28 July 1975 [26 Aug 1974] 31441/75 Heading F2D A valve for controlling the rates of pressurization and depressurization of hydraulic actuators of a brake and a clutch which establish second and third speed ratios in an automatic change-speed transmission of a vehicle comprises a spool valve element 4 controlling flow of fluid to and from a third speed clutch K, and a spool valve element 5 loaded by a spring 3 and controlling flow to and from a second speed brake B. The valve elements are shown in the positions they occupy when conduits 1, 2 connected respectively with 2-3 and 1-2 shift valves (not shown) are vented, the transmission then operating in low ratio. When the 1-2 shift valve selects second speed it supplies a load-dependent principal pressure to the conduit 2 which communicates with the brake actuator through an unrestricted path 22, 221, 231, 23 and parallel paths with restrictions 223, 21. At the same time a reservoir R1, comprising a spring-loaded differential piston loaded by the principal pressure, is charged. When the pressure which acts in a chamber 55, reaches a value to overcome the spring 3 the valve element 5 is displaced to a position in which an abutment 52 engages the end wall of the chamber 6 and the unrestricted passage 231 is closed so that further build up of pressure is controlled by the restrictions 223, 21. Progression to third speed is initiated when the shift valves pressurize and vent, respectively, the conduits 1, 2. The clutch actuator and a reservoir R2 connected through a restriction 132 are then filled through passages 12, 13 and a parallel passage with restriction 11, and when pressure acting on a surface 42 of the valve element 4 overcomes the pressure in the chamber 55, which falls as the brake actuator is vented through the restrictions 223, 21 and a parallel restriction 234 controlled by a non-return valve 235, the valve element 4 moves to close the passage 12 and the passage leading to the restriction 223. Build up of pressure in the clutch actuator and reservoir R2 then takes place solely through the restriction 11. In the 3-2 shift the brake actuator is pressurized solely through the restriction 21 and the clutch actuator is exhausted solely through the restriction 11 until the falling clutch pressure acting on the surface 42 is overcome by the rising brake pressure in the chamber 55 whereupon the valve element 4 is displaced to open the unrestricted passage 12 and the passage with the restriction 223. Due to the employment of the load responsive principal pressure, to which both reservoirs R1, R2 are subjected, the rates of clutch and brake operation and the engagement pressures are load responsive, being highest during kick-down.

Abstract: 652,259. Pressure gauges; indicating and recording apparatus. SOC. ANON. DES ETABLISSEMENTS J. COCARD. Nov. 28, 1947, No. 31600. Convention date, June 19, 1942. [Classes 106 (ii) and 106 (iv)] In a measuring apparatus an element 1, sensitive to variations in the magnitude to be measured, e.g. speed or pressure, actuates an indicating or recording element successively through different links 2, 5 having different transmission ratios, thus opening out part of the indicating or recording scale relative to the rest. In the pressure gauge shown, a Bourdon tube 1 has a fork 6 at its free end, the arms of which are connected by the links 2, 5 to studs 7, 3 respectively, adjustably fixed on an extension 19 of a gear sector 9 at different distances from its pivot 18. The sector meshes with a pinion (not shown) on an indicating pointer axle 16. The studs 3, 7 engage slots in the links so that only one link is effective at a time, each link acting for a different pressure range. The length of link 5 can be adjusted to alter the point of change-over from one link to the other. The movable pointer may be replaced by a fixed index and a rotating indicating drum, or by a stylus recording on a drum to which is given a rotary and translatory motion. The Specification as open to inspection under Sect. 91 describes also an electric contact on the indicating pointer which engages a fixed contact to close a circuit when a certain pressure is reached. This subject-matter does not appear in the Specification as accepted.
