Title: Improvements in and relating to lighting systems for road vehicles
IPC: B60Q1/14
Filed: 1932-11-12
Abstract: 415,021. Switching systems for motor-vehicle lamps. VASILACHE, S., 14, Boulevard St.-Jacques, Paris. Nov. 12, 1932, No. 32059. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 15, 1933]. [Class 38 (iv).] Head and dim lamps 12, 14 of a vehicle are selectively energized by a relay 10, 6 in the circuit of an amplifier valve 4 the grid-cathode voltage of which is obtained from across a tap in a battery 5, 7 and the junction between a variable resistance 3 and a photo-electric cell 2 in series in the battery circuit. Illumination of the cell 2 by the head lamps of an approaching car causes operation of the relay 10 to de-energize the head lamp 12 and energize the dim lamp 14. A source of visible or invisible radiations 15 is also energized to operate on the photo-cell 2 of the apparatus on the approaching vehicle. A hand switch 17 permits de-energization of the lamps 14, 15 at will and energization of the head lamp 12 for the purpose of signalling. A switch 18 permits permanent illumination of the dim lamp 14.

Title: Improvements in the assembly of ball bearings
Inventor: REINDORP EDWARD
IPC: F16C43/06
Filed: 1959-09-21
Abstract: 885,541. Bearings. TEDDINGTON INDUSTRIAL EQUIPMENT Ltd. Sept. 21, 1960 [Sept. 21, 1959], No. 32086/59. Class 12 (1). In a method of assembling ball bearings, the balls are positioned in the correct spatial relationship for assembly into a cage by jets of fluid under pressure. In an embodiment balls 1 are fed into races 2, 3 and the assembly is supported by an annular rib 4 of a wind-chest 6 which has a circle of equally spaced air jets 5, each of which lifts a ball. A vibrator 7 serves to support the chest 6 and to move the balls to the jets. The cage comprises upper and lower parts 8, 9, the former being assembled first to allow the bearing to be transferred to a table 11 having the lower part 9 thereon which is secured to the upper part 8. The vibrator may be replaced by tangentially-directed air streams which move the balls and/or the races, the latter preferably should be allowed to "float." The supporting of the balls on the jets causes a back-pressure in the supply-line 10 and this could be used as a signal to initiate the automatic assembly of the top half of the cage into the bearing.

Title: Apparatus for feeding the pile board of a sheet separating device
Inventor: LANGE WERNER
IPC: G03B27/58
Filed: 1971-07-08
Abstract: 1283500 Feeding sheets PENTACON DRESDEN KAMERAUND KINOWERKE VEB 8 July 1971 32125/71 Heading B8R A cassette 2, Figs. 1 and 2, containing a pile of sheets 1 and closed by a locking slide 4 is inserted between shutters 7, 8 into a housing above a pile table 11. The slide is withdrawn and the pile falls on to the table. A hand lever 20 is then depressed, and this movement causes the table, which is mounted on parallel pivoted pairs of arms 15 (a, b), 16(a, b) to be lowered, and also causes a member 24 to move in a recess 25 in the table to push the pile against a front stop 40 and a member 31 to push it against a side stop 45. On release of the lever 20, a spring 19 raises the table until the pile moves up into contact with a separator friction roller 39 which moves the sheets in succession between the stop 40 and a bar 41 to feed rollers 42. When all the sheets have been removed, the empty cassette is withdrawn. Slight depression of the lever 20 now releases a latch 33 from a lever 29, and springs return the members 24, 31 to their original positions ready to receive a new pile. In another form, Fig. 5, a reversely rotating member 46 withdraws the top sheet from under a holding member 47 on the front step 48 and bends it by pressure against a rear holding member 50, after which a rotating segment 49 feeds it to the rollers 42. In another form, Fig. 7, two piles of sheets introduced by the means described above, rest on tables 11b, 11c, which are moved by similar mechanism, and two sheets, one separated from each pile by similar mechanism, are brought together to a common pair of feed rollers. The housing is light tight and forms part of a photocopying apparatus.

Title: Improvements relating to the electrical control of bulkhead and like remotely controlled doors
IPC: E05F15/00
Filed: 1936-11-24
Abstract: 485,758. Electromagnetic switches. STONE & CO., Ltd., J., and JAMES, D. E. Nov. 24, 1936, No. 32142. [Class 38 (v)] [Also in Group XXV] In an electric control system for ships' bulkhead doors and like remotely-controlled doors, the control operations are performed in a given sequence and with a given timing by an automatically driven controller switch, the driving of which is initiated by a manual switch. In the arrangement shown, a stepping switch of the kind used in automatic telephony is used, comprising several banks of contacts such as A along which wipers such as a are advanced intermittently, while the switch is in operation, by a ratchet driven by an electromagnet 36; the lowest bank of contacts serves for the operation of the switch, the one above operates an alarm bell, and the remainder control doors. If, in the off position shown, the button 47 is pressed momentarily, the stepping magnet 36 is energized momentarily and on de-energization the wipers are moved on to the first contacts of their banks. The circuit of the bell is thus closed, and a charging circuit for a timing condenser 40 is also closed ; after a definite time the condenser discharges through a neon lamp 42 and a relay 39 which completes a circuit for the stepping relay 36 ; the latter relay also closes contacts 46 to complete the discharge of the condenser. The wipers thus move along the banks of contacts at a speed determined by the condenser 40. and the bell ceases to operate. The doors are brought into operation after intervals of time determined by the connections of their respective banks of contacts. The stepping operation stops while the door mechanisms are still energized to hold the doors closed ; a second operation of the button 47 moves the wipers on one step to the position shown in which all the circuits are broken and the doors are free to be re-opened locally. The apparatus may be arranged for opening some or all of the doors from the central control position, and a selector switch may be used to select one or more of the doors for closing when required.

Title: Improvements in and relating to highly sensitive electric relays
IPC: G01R13/00
Filed: 1933-11-21
Abstract: 427,758. Light - current relays; electromagnetic switches. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN - EN APPARATEN FABRIEKEN MEAF, (formerly NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN), 30, Croeselaan, Utrecht, Holland. Nov. 21, 1933, No. 32521. Convention date, Nov. 21, 1932. [Class 38 (v)] [See also Groups XXXVI, XXXVIII, and XL] In a normally energized relay in which the movable member is normally held in a definite position by the current, an additional force is arranged to act automatically on the movable part as it approaches the zero position on failure of the current, before it initiates a switching operation. In the arrangement shown in Fig. 1, the pointer 1 of an electric measuring instrument carries a small armature 2. When the current in the instrument fails, the pointer is returned towards the zero position by a weak returning force, until the armature is attracted by a magnet 3 which accelerates the pointer to the zero point or beyond it and separates the contacts 4, 5. As employed in a lamp failure alarm system, Fig. 2, the instrument is fed from a source of current 1 which varies in accordance with the light or heat derived from the lamp A, the current normally maintaining the pointer 3 of the instrument at the dotted position. On the failure of the lamp, the decrease in current brings the pointer to or near its zero position in which the armature carried by the pointer comes within the range of attraction of a permanent magnet 5. This ensures a prompt separation of spring contacts 7, 8 by a projection on the pointer engaging the former, so opening the circuit of a relay 15 which by dropping its armature closes contacts 12, 13 in the circuit of an alarm bell B. To restore the pointer to its former position against the attraction of the magnet 5 after the light source A is again in operation, the magnet may be rotatable or a pivoted arm 17 may be rotated in an anticlockwise direction to engage an extension of the pointer. Other arrangements, e.g. remotely controlled electromagnets may be employed for this purpose. The arm 17 may be provided with a bridging contact so that on clockwise rotation it may short-circuit the relay 15. The permanent magnet 5 may be provided with magnetic screening devices to limit the range of its operation in conjunction with the armature carried by the instrument pointer.
