Abstract: 503,626. Cash registers. NATIONAL CASH REGISTER CO. Oct. 15, 1937, No. 28151. Convention date, Oct. 17, 1936. [Class 106 (i)] Differential mechanism.-A differential mechanism for a cash register or similar accounting- machine comprises an actuator having an inclined slot therein, a plate having a slot inclined substantially at right-angles to the slot in the actuator, and a pivoted latch having a pin projecting through the slots so as to connect the actuator and plate to a driver, the plate being resiliently connected to the actuator to hold the latch in engagement with the driver and to permit the latch to become disengaged from the driver when the actuator is arrested. The invention is described as applied to a machine of the Shipley type forming the subjectmatter of Specification 8119/15, [Class 106 (i)]. The differential mechanism for each amount bank now includes a differential actuator 63, and a latch 102 pivoted on an arm 103, both the actuator and arm being freely mounted on a shaft 94. The latch is connected to the actuator by a stud 104 projecting from the latch into an inclined slot in the actuator. The stud is normally held in the lower right-hand part of the slot by a disc 106 freely mounted on shaft 94 and coupled to the actuator by a spring 107, the disc being provided with a slot 108 embracing the stud 104 and disposed substantially at right-angles to the slot 105. With the stud in this position, the latch takes over a shoulder 109 of a driver that receives a constant clockwise and counterclockwise excursion during each cycle from cams on the main shaft 61. The latch and actuator are thus constrained to follow the clockwise movement of the driver until the actuator is arrested. by the abutment of its face 110 with a zero stop pawl 76 or the stem of a depressed key 62. Continued movement of the driver causes the stud 104 to move along the slot 105, whereby the latch is disengaged from the driver and engaged with one of a series of registering notches 112. During the counterclockwise movement of the driver, a stud 129, projecting therefrom, abuts and restores the actuator. In total-taking operations, the actuator is arrested by the abutment of the transfer tooth 136 of the engaged totalizer pinion 93 with a transfer pawl 137, in the manner described in Specification 506,829.

In Figs 1 and 2, a U-shaped pin 40 provided for retaining the brake pads radially is clipped at 41 to the floating caliper 20. One end of the pins slides in an axial passage 44 provided in a projection 42 forming part of the fixed cylinder casing. After a definite degree of wear of the friction linings the caliper 20 will have been moved a sufficient distance in the direction of arrow 65, Fig. 1, for the pin to press inwards a plunger 57-64, Fig. 2, against the force of a spring 147 until extension 64 comes into contact with a bead 40, thus closing a circuit (not shown) including a luminous or audible warning device disposed, e.g. on the vehicle dashboard. In Fig. 4 a deformable metal strip 71 is permanently electrically connected at one end, 75, 76, and has a Vee-shaped middle portion 77, the assembly being secured to the stationary bearer 11 and protected by a pliable dust-excluder 80. Again, after defined wear, caliper 20, moving in direction 20, moves strip 71 until a contact bead 78 on its free end touches bearer 11, thereby closing a warning circuit as before.

In order to reduce the air turbulence in the empty converters with the drive in the opposite direction where the pump and turbine wheels are rotating in opposite directions which may cause heating flow obstacles are introduced into the flow path to block the passage through the reaction member. In Fig. 2 resilient tongues 29 are spot welded to the reaction member cover disc 33 and obstruct the passage when the converter is empty but are forced aside into contact with the work chamber wall when it is filled. In Fig. 6 a ring slide 45 is inserted into the passage by pressure in an hydraulic cylinder 46 derived from a linked valve 48 which controls the filling and emptying of the chamber. In other embodiments resilient tongues may be directly attached to the blades to obstruct the passages between them when the chamber is empty or alternate blades may be pivotable to obstruct the passages or parts of the blades may be moved to obstruct the intervening passages.

Filed: 1975-12-23
Abstract: 1497600 Controlling input/output devices FUJITSU Ltd 23 Dec 1975 [29 Dec 1974] 52752/75 Heading G4A In data processing apparatus controlling operation of I/O devices designated by preassigned device identification numbers, the input/output devices fall into at least two groups, a first group which may be operated in parallel on a time-sharing basis, each device in this group having an individual location in a control data memory assigned to it, and a second group of devices operated individually, the control data memory storing, at different times when the apparatus is in use, control data for devices of the second group. As described there are three groups, the first of which is connected to a multiplexer channel (MXC, Fig. 1, not shown) and comprise low speed devices, e.g, card readers, punches, line printers transferring data by byte. The second group is connected to a block multiplexer (BMC) and includes magnetic discs and drums which transfer data as a block of bytes. The third group are also connected to a block multiplexer and include tape units transferring data by blocks of bytes. When accessing the memory for control data relating to a device of the first group, address information to read out a unit control word is derived directly from the device identification number. For control data relating to the second group the device identification number is first shifted right by three bits and the first two bits are forced to 1 0 (to indicate a block multiplexer channel), the resulting address being used to access a table from which a seven bit address (and a one bit validity check) is read out. This address is used in conjunction with the three least significant bits of the original device identification number to access the unit control memory. Space is assigned in the control word memory for this group by entering the contents of an assign counter into the pertinent assign table location and using this address to store the unit control word to be employed in the control word store. The assign counter is then incremented before storing the next unit control word. When accessing the memory for control data relating to devices in the third group access is first made to the assign table and then to a one unit control word memory domain. The address read from the assign table indicates that the device is in the third group and a pair of bytes are then read out. Storing of unit control words for this group is under the control of a management program. Circuitry (Fig. 9) for controlling the three types of operation includes a register 103 for the device number, a shifter 106 employed when a device of the second group is accessed and an arithmetic and logic unit 101 to which the contents of the assign table are sent (1) for comparison with the boundary address for Groups 2 and 3, (2) to derive the address for the memory for devices of the second group and (3) to determine which two bytes are to be read for devices of the third group. An error check circuit is also included.
